Rajendra M. Kawade, Nitin B. ghiware, Mahavir H. Ghante, Shripad M. Malwatkar, Sudhir M. Vadvalkar, Avinash K. Dhadwe, Rushikesh V. Choudhary

Kalanchoe pinnata (Family: Crassulaceae) is an important plant which has many traditional medicinal uses. The main objective of this literature review was to give advance information for the drug discovery research for K. pinnata. It was found that this plant showed various pharmacological activities such as anthelmentic, immunosuppressive, wound healing, hepatoprotective, antinociceptive, anti-inflammatory, antidiabetic, nephroprotective, antioxidant activity, antimicrobial activity, analgesic, anticonvulsant, neuropharmacological and antipyretic. Anthelmentic activity was found due to the presence of tannins of the extract of K. pinnata and steroid glycosides such as bufadienolide showed wound healing activity. It was also found that the different flavonoids, polyphenols, triterpenoids and other chemical constituents of the plant were responsible for the antinociceptive, antiinflammatory and antidiabetic properties. Quercetin had a marked protective effect on cadmiuminduced nephrotoxicity and possessed potent oral efficacy against cutaneous leishmaniasis. The two new novel flavonoids such as 5Methyl 4, 5, 7 trihydroxyl flavone and 4, 3, 5, 7 tetrahydroxy 5-methyl 5 Ipropenamine anthocyanidines could be responsible for the antimicrobial activity of K. pinnata. Five bufadienolides (1-5) isolated from the leaves of K. pinnata were potential cancer chemopreventive agents. Quercitrin, a flavonoid, is a critical component of K. pinnata extract against an extreme allergic reaction. This literature review gave the evidence based information regarding the pharmacognostical, phytoconstituents and pharmacological activity of the medicinal plant, K. pinnata which could help researchers for more advanced qualitative research.

Approaches for improvement of vesicular system-Pro-vesicular drug delivery

Gangadhar Veerapu, Gangadharappa.HV, B Nagashubha

Drug delivery systems using colloidal particulate carriers such as liposomes and niosomes have distinct advantages over conventional dosage forms. This class of drug carrier systems will likely play an increasingly important role in drug delivery. However, there remain significant problems like instability in the general application of liposomes and niosomes for drug delivery. Pro vesicular drug delivery developed to overcome the stability problems associated with vesicular drug delivery systems composed of water soluble porous powder as a carrier drug is dissolved in an organic solvent to produce free-flowing granular product. To overcome the limitations (especially chemical and physical stability) of vesicular drug delivery systems like liposomes, niosomes, trans-ferosomes, and pharmacosomes, the pro-vesicular approach was introduced. The present article gives a brief overview of introduction on proliposomes, Pro-niosomes, Dry granular liposomes, mixed micellar proliposomes, Pro-transferosomes and its applications.

Review On: High-Throughput Screening Is An Approach To Drug Discovery

Ashok A. Hajare, Sachin S. Salunkhe, Sachin S. Mali, Sonali S. Gorde, Sameer J. Nadaf, Sachin A. Pishawikar

High-Throughput Screening (HTS) is an approach to drug discovery that has gained widespread popularity over the last two decades and has become a standard method for drug discovery in the pharmaceutical industry. Progress from traditional one-compound-at-a time approach, low throughput screening to high throughput screening involving fully automated robotic systems, enables testing of large numbers of compounds daily for different activities in miscellaneous areas of biology. HTS reveals screening of more than 100,000 samples per day. Compared to traditional drug screening methods, HTS is characterized by its simplicity, rapidness, low cost, and high efficiency. Identification of good hits using HTS can minimize the time span of drug discovery noticeably. However, synthetic chemistry for lead optimization and the low throughput of secondary assays for defining the crucial pharmacological properties of active compounds, limits the overall rate of identification of candidate molecules for clinical evaluation. Coupling of compound library with wide chemical diversity along with HTS shows massive drug discovery potential, but to be successful screening technique it depends on several factors. These include the number and quality of validated targets, the number and diversity of compounds in the collections, and the ability to screen these in a timely and cost effective manner using robust informative assays. In this review we have discussed the types of HTS assays, assay miniaturization automation and different detection techniques like fluorescence resonance energy transfer (FRET), fluorescence polarization (FP), homogeneous time resolved fluorescence (HTRF) etc.

Swati A. Pagar, Dattatreya M. Shinkar, Ravindra B.Saudagar

Quality by design is an essential part of the modern approach to pharmaceutical quality. Quality by design (QbD) is more scientific, risk based, holistic and proactive approach in pharmaceutical development for FDA and pharmaceutical industry in drug development. Quality by Design (QbD) is everything you do to directly to promote, prove safety, efficacy and quality of your product from proof of concept to the point at which costumer are buying on regular basics. This novel concept of QbD promotes industries in understanding product and manufacturing process starting with product development which aims basically building quality in product, not by testing it. A company needs to define desire product performance profile [Target product Profile (TPP), Target Product Quality Profile (TPQP)] and identify critical quality attributed (CQA) under this concept of QBD during designing and development of a product. On the basis of information obtained company can build consistent product quality by monitoring and updating its manufacturing processes. This systematic approach to product development and manufacturing has received a great deal from traditional approach. The purpose of present article is to discuss the concept of pharmaceutical Quality by Design (QbD) and describe how it can be help to ensure pharmaceutical quality.

Over the past few decades, there has been an increased interest for innovative drug delivery systems to improve safety, efficacy and patient compliance, thereby increasing the product patent life cycle. There are novel types of dosage forms that act very quickly after administration. The basic approach used in development tablets is the use of superdisintegrants like Cross linked carboxymelhyl cellulose (Croscarmeliose), Sodium starch glycolate (Primogel, Explotab), Polyvinylpyrrolidone (Polyplasdone) etc. which provide instantaneous disintegration of tablet after administration. Immediate release liquid dosage forms and parenteral dosage form have also been introduced for treating patients. Liquid dosage form can be suspensions with typical dispersion agents like hydroxypropyl methylcellulose, AOT (dioctylsulfosuccinate) etc. The development of immediate release therapy also provides an opportunity for a line extension in the marketplace, A wide range of drugs (e.g., neuroleptics, cardiovascular drugs, analgesics, antihistamines, and drugs can be considered candidates for this dosage form. In this regard, immediate release formulations are similar to many sustained release formulations that are now commonly available. oral film dosage form not only has certain advantages of other fast disintegrating systems but also satisfies the unmet needs of the market. The present review emphasizes on the potential benefits, design and development of robust, stable, and innovative orally immediate and their future scenarios on a global market as a pharmaceutical dosage form.

Nasal Microspheres as a Potential Carrier in Nasal drug delivery

Digambar Yashawant Mali, Ajay Gorakhnath Vishwakarma, Mrs.Swati Gokul Talele, Rajendra Tryambak Mogal

Micro-particulate systems have already shown their potential as a carrier in delivery of many therapeutic molecules. Due to this potential, such systems are now most preferred over other conventional systems of drug delivery. Micro-carriers (Microspheres) shows features like controlled release, improvement in the residence time and thus enhancing bioavailability of administered drug. Nasal microspheres are now a day’s becoming more popular for delivery of many therapeutic moieties. For building of microparticulate systems polymers from natural and synthetic origins are generally used. Drugs which are not suitable for oral administration due to high first pass effect (i:e presystemic metabolism), instability in gastrointestinal tract can be successfully delivered via nasal route. Systems like mucoadhesive microspheres provide sufficient time for drug to remain in contact with mucosal membrane so as to increase their absorption. This is the basic underlined reason suggests why most of the polar drugs have shown improvement in the bioavaibility when compared with their conventional intranasal formulations. This review mainly focuses on the basic aspects of microspheres as a potential carrier in the drug delivery.

Similarities and Differences between different proton-pump inhibitor formulations for the treatment of gastro esophageal reflux disease – A Review

Subrahmanyam PVRS, Chinna Reddy P, Jithan Akunuru2 and Satyanarayana K

Gastro esophageal reflux disease is a chronic, recurrent disease that affects millions of people worldwide. Proton pump inhibitors are a group of drugs whose main action is a pronounced and long-lasting reduction of gastric acid production. These drugs are utilized in the treatment of many conditions such as Dyspepsia, Peptic ulcer disease, Gastro esophageal reflux disease. Currently proton pump inhibitors are available in both oral and injectable formulation. Proton pump inhibitors are substituted benzimidazoles that inhibit gastric acid secretion via inhibition of the gastric H+/K+ ATPase pump. Although there are some differences in pharmacokinetics and binding affinity for the pump, these drugs are comparatively similar in their efficacy in treatment of gastric diseases. The delayed release proton pump inhibitors effectively suppress gastric acid secretion and successfully treat acid-related disorders. Each differs somewhat in its formulations. The difference in the formulations has not been translated into clinical advantages over the delayed release proton pump inhibitors. Novel multiple formulations approaches are required for proton pump inhibitors to enhance acid suppression. Although the individual proton pump inhibitors have similar efficacy in many cases, differences between them should be considered when choosing a treatment regimen.

A Review on In Vitro Methods and Factors Affecting Nasal Drug Absorption

Prashant Suresh Devmore, Bhagyashree Tulashidas Chothe, Ravikumar Prabhakar Kamble, Pravin S. Waghchoure, Saurabh Vinod Raut, Raghwendra R. Waghmode

Nasal drug delivery is an excellent approach for avoiding first pass effect of oral dosage form. It offers a direct systemic delivery of drugs. Nasal administration can therefore be used as an alternative to oral administration for example tablets and capsules if a fast effect is desired or if the drug is extensively degraded in the gut or liver. The primary goal of this article is to study factors affecting nasal drug absorption and the in-vitro methods available for nasal absorption of drugs. There are many in-vitro models for testing absorption studies and it has many advantages over in-vivo methods such as a controlled environmental study of epithelial cell growth and differentiation, drug transport pathways and mechanisms are elucidated easily, it has very fast means of evaluating drug permeability and to minimize expensive use of animals. Cell culture and cell line models were found to be best for nasal in-vitro absorption studies. Similar results are obtained from in-vitro studies. So by using in-vitro methods one can mimic the in-vivo conditions. It avoids disadvantages of in-vivo study. It was concluded that in-vitro models mimics the results of in-vivo study. But up till now no any system is superior to one another. Keywords- In-vitro methods, nasal drug absorption, PDMS and Culture models.

Apoorva Agarwal, Priyanka Bhat, Vandana Jugran Negi, Ankush Sundriyal

Over the past decade, numerous limitations of conventional dosage forms had attracted researchers to find a rational and appropriate drug delivery system. Microsponges were developed and studied as a novel programmable delivery system which is intended to deliver drug in controlled release pattern. It also aims epidermal localization of topical drug therapy to reduce their side effects by limiting systemic absorption through skin. Drug loaded microsponges are microporous beads, typically 10-25 µm in diameter which can entrap a wide variety of actives and can be formulated as creams, lotions, gels, ointments, powders, soaps. Microsponge formulations can increase product stability, enhance aesthetic qualities, and provide formulation flexibility and stability. Moreover, their non-antigenicity, non-toxicity, non-mutagenicity and non-biodegradability make them favourable candidates. Microsponge approach has also been applied in oral therapy, bone, tissue & cartilage engineering and showed remarkable results. This article provides description about the nature of microsponges, their characteristics, preparation, applications and commercial market status globally.

Studying the Effect of Genetic Diversity in Samples of Iraqi Arthritis Patients on Response to Drug Treatment Using RAPD/PCR Technology

Amina Nimaa Al-Thwani, Ibtsam Adnan Ibraheam El-Baghdadi

Rheumatoid arthritis (RA) is an autoimmune disorder of unknown etiology, despite therapy may result in progressive joint destruction, deformity that lead to disability, and even premature death in some cases. Random Amplified DNA Polymorphism (RAPD) technology showed high efficiency in investigating the genetic diversity between healthy control group and RA patients and detecting the genetic diversity among RA patients and the effect of this diversity on the patients response to the drugs regimens used to treat RA. The primers GATGACCGC and ACAACGCCTC showed the best ability to discrimate between the healthy subjects and the RA patients, and the primers GATGACCGC, ACAACGCCTC and CAGCACCCAC showed the best ability to detect the genetic diversity among RA patients and detecting the effect of this diversity on the patients' response to treatments. Analysis of the resulted pattern of amplifications through the Unweighted Pair Group Method with Arithmetic mean (UPGMA) algorithm program revealed an important thing which is the fact that RAPD technology is an important relatively cheap and available technology that can be used in pharmacogenomics because of the fact that there is an association between the genetic content of the patients and their response to different treatment regimen.

Surveillance of Multi-drug resistance of Salmonella Typhimurium strains. Twenty years review.

Naxhije Hila, Klementina Puto

Today all over the world Salmonella typhimurium is one of the most frequent causes of food poisoning in humans. The antimicrobial resistance of salmonellas has increased rapidly during the last decade, creating a serious threat to the treatment of infectious diseases. This study will introduce the multi-drug resistance of 2931 Salmonella typhimurium strains isolated in patients diagnosed with salmonellosis or in carriers of salmonellas in the region of Elbasan, Albania during 1985-2004. All Salmonella typhimurium strains isolated during this period have been tested using impregnated discs with the most common used antimicrobial agents. S.typhimurium strains have shown resistance toward antibiotics as follows: Te+S, 64.04%, Te+C, 58.24%; S+C, 55.85%, Te+S+C, 53.46% while the multi-drug resistance shown is 87.17%. This multi-drug resistance of the strains isolated during 1985-2004 is comparable with the data represented by some native and international authors.

In-vitro Efficacy Analysis of Few Essential Oils for their Antibacterial Activity against Methicillin Resistant Staphylococcus Aureus

Shuchi Kaushik, Preeti, Bhatnagar, Raghvendra Kumar Mishra, Archana Shrivastav, Sudhir Kumar Jain, Rajesh Singh Tomar

Hospital acquired infections are commonly associated with Methicillin Resistant Staphylococcus aureus infection and treating these infections with chemotherapy is very perilous. The augment of multidrug-resistant strains makes it necessary to discover new classes of antimicrobials and compounds that restrain their resistance mechanisms. In the past few decades, the search for new anti-infective agents has betrothed many research groups in the field of ethno pharmacology. Many focus on determining the antimicrobial activity of plant extracts found in folk medicine, essential oils or isolated compounds. There are a large number of species that have been and are still used as medicinal plants, particularly in folk medicine. In the present study, we analyse the possibility of essential oils as potential antimicrobial crude drugs as well as a source for natural compounds that act as new anti-infectious agents.

Tripura Sundari P, Gaud RS, Richa Shah

Drug delivery via nanoparticle-based carriers has shown promising results for different types of diseases. Delivery of anti-gout agents into body is a mature line of investigation that has yet to realize its full potential. In this study we report on the development of a delivery platform for febuxostat. The work presented here describes the development of nanoparticles based on compritol. The method employed for the preparation of SLN is micro emulsification technique followed by high pressure homogenization. Phase diagram was developed to know the region of stable micro emulsion formation. Eight different formulas were developed with different concentrations of lipid, surfactant and aqueous concentrations. The developed formulations were evaluated for particle size distribution, zeta potential, entrapment efficiency, DSC thermal analysis and in vitro drug release studies. Among all the formulations developed, F3 formulation is showing better drug entrapment efficiency and controlled release of drug up to 24h. There was 12 fold increase in the solubility of drug in the developed formulation. The solid lipid nanoparticles of febuxostat can be prepared by using simple micro emulsification technique. The formulations had shown better release profile and solubility characteristics.

Ruhul Kayesh, Md. Sharif Hasan, Md. Zakir Sultan

A rapid and stability indicating ion-pair reversed phase high performance liquid chromatographic method was developed for qualitative and quantitative estimation of three oxicam drugs: tenoxicam, meloxicam and lornoxicam. The method was validated according to ICH, FDA and USP guidelines with respect to accuracy, precision, specificity, linearity, solution stability, robustness, sensitivity and system suitability. The method was developed by using an isocratic condition of mobile phase comprising buffer pH 6.5 [tetra butyl ammonium hydroxide (0.008M) and sodium 1-heptane sulfonate (0.003M)] and acetonitrile in a ratio of 65:35 v/v ratio at a flow rate of 1.5 mL/min over C-18 (ODS, 250 x 4.6 mm) column at ambient temperature. The method showed linear response with correlation coefficient (r2) value of 0.999. The recoveries for all drugs were found more than 99% which demonstrated the accuracy of this method. Intraday and inter-day precision studies of the new method were less than the maximum allowable limit (RSD%£ 2.0). Forced degradation studies were carried on to check its stability indicating property. All the drugs gave sharp peaks within 7min with excellent symmetry and high resolution. Therefore, a rapid, sensitive and stability indicating ion pair RP-HPLC method was developed for simultaneous separation of tenoxicam, meloxicam and lornoxicam in their any combination or in bulk raw materials.

Abdelhady S, El Ashmawy N, El Bahrawy H, Fouad H

A potential mechanism of NSAID-mediated anti-proliferative activity may be through the induction of NAG-1. The present study was conducted to investigate the possible role of selective and non-selective COX inhibitors in inflammation associated angiogenesis and apoptosis. Wistar rats were classified into 5 experimental groups; 9 rats each. Group (1) normal control and group (2) injected s.c. with 0.3 % carrageenan in muscle. Groups (3, 4 and 5) were injected s.c. with carrageenan and at the same time given orally 10 mg/Kg Celecoxib, 12.5 mg/Kg Nimesulide or 10 mg/Kg Sulindac, respectively. NAG-1 gene expression in the liver was measured by RT-PCR. Serum TNFα and muscle caspase-3 were measured by ELISA.Immunohistochemical detection of VEGF in the muscle was investigated. Carrageenan untreated rats showed insignificant change in NAG-1 gene expression compared with control group. Serum TNFα and muscle caspase-3 as well as VEGF expression in carrageenan untreated group were significantly increased compared with normal control rats. In Sulindac treated group, NAG-1 gene expression in the liver and muscle caspase-3 were significantly increased compared with Celecoxib and Nimesulide groups. TNFα serum level was significantly decreased in Nimesulide and Celecoxib treated groups compared with carrageenan and Sulindac groups. The examined NSAIDs proved proapoptotic and antiangiogenic effects.

The present study was carried out in fabricating gastro retentive formulation of an antipsychotic drug using semi synthetic and natural polymers. Floating tablets were prepared by direct compression method using directly compressible microcrystalline cellulose as vehicle. Gum Xanthan and hydroxypropyl methylcellulose (HPMC E4M) were used as polymers for sustaining the drug release and sodium bicarbonate was used as an effervescent agent. Tablets were characterized for their pre compression and post compression parameters. Floating characteristics like floating lag time, floating time were evaluated and were considered as one of the factor for selecting the best formulation. The in vitro release studies were carried out in pH 1.2 buffer for 8hrs. The content uniformity was found to be within the compendial requirements and the release was extended for more than 8hrs. The best fit release kinetics was achieved with zero order followed by higuchi and non-fickian diffusion. The release of Quetiapine fumarate was significantly influenced by the concentration of polymer.

Effect of Iontophoresis On In-vitro Transdermal Delivery of Tramadol, A Centrally Acting Analgesic

Hiral Shah, Jigar Shah, Bharadia Praful

The aim of the present work was to characterize the in vitro transdermal absorption of tramadol hydrochloride (TH) through pig ear skin. Studies of electrical and physicochemical factors acting on the permeation kinetics of in vitro iontophoresis were performed. Iontophoresis increased the transdermal permeation flux of TH as compared to the diffusion. Increase in applied current density or enhanced the flux of the drug. Continuous current was more potent than pulsed current in promoting TH transdermal permeation. Increasing the frequency or on:off ratio of pulse current induced an enhancement of the flux through the skin. The binary system did not cause an enhancement in the permeation of TH compared to water alone. An increase in donor drug loading dose or increasing the duration of current application resulted in enhancement of the drug flux. Based on these results, and taking into account the pharmacokinetics of TH, therapeutic drug plasma levels could be achieved via transdermal iontophoresis using a reasonably sized (around 20 cm2) patch.

Formulation Development of Fixed Dose Combination of Metoprolol Succinate Extended Release Pellets and Atorvastatin Calcium Immediate Release Drugs

Anil Kumar chandragiri, Thirupathi Kaluvala, Vijaykumar Nagabandi 2 Kranthi Raju palle

The main objective of current research work was to develop a stable pharmaceutically equivalent combined dosage form of immediate release Atorvastatin calcium and extended release Metoprolol succinate formulation, which is comparable to that of innovator’s. Combination therapy affords the physician and the patient the opportunity to more effectively treat diseases that may stem from more than one cause. When used correctly and appropriately, combination therapy leads to better outcomes than mono therapy by treating more than one cause of the disease and/or by synergistically enhancing the action of one of the component drugs. The purpose of the study was to develop a capsule of Atorvastatin calcium (IR) and Metoprolol succinate (ER) having different release pattern, which is indicated for the management of hypertension. The study was planned in three stages. In the first stage three batches (A1, A2, and A3) of immediate release blend of Atorvastatin calcium was prepared using pre-gelatinized starch as super disintegrate. In the second stage, nine batches (M1-M9) of Metoprolol succinate sustained release pellets were prepared using various polymers and levels of coatings as rate retardants. Preformulation studies were performed after granulation. In the third stage capsules were evaluated for weight variation, drug content, and disintegration time and in vitro drug release using RP-HPLC. FTIR studies revealed no disturbances in the principle peaks of pure drugs and it confirms the integrity and compatibility of pure drugs with their excipients.

Determination of Darifenacin in Human Plasma by a Novel LC–MS/MS method by using Protein Precipitation technique

Boligarla Gopi Kalyan Kumar, Vasu Babu Ravi, Sesharatnam Padala 3 and N. Y. Sreedhar

In this paper the authors proposed a simple, sensitive and selective liquid chromatography–tandem mass spectrometry (LC–MS/MS) assay method for the determination of darifenacin in human plasma. This method employed solifenacin as an internal standard (IS). Analyte and the IS were extracted form 200 µL of human plasma using protein precipitation technique. The chromatographic separation was achieved on a C18 column by using a mixture of acetonitrile and 5mM ammonium formate in 0.01% formic acid (90:10, v/v) as the mobile phase at a flow rate of 1.0 mL/min. The linearity of the method was established in the concentration range 0.05–20.5 ng/mL with r2 ³ 0.99. The intra–day and inter–day precision (%CV) and accuracy results in three validation batches across five concentration levels were well within the acceptance limits. The validated method was successfully applied to a pharmacokinetic study in humans under fasting condition with 15 mg darifenacin extended release tablet.

Seema Rai, Preethi G Pai, Rajeshwari S, Ullal Sheetal D, Nishith RS, Yogesh Belagali

Mucuna pruriens commonly known as cowhage plant has been claimed to possess various beneficial effects like anti-parkinsonian, anti-tumor, neuroprotective, antioxidant, anti-diabetic and antidepressant activities. Previous studies have reported that Mucuna pruriens contains L-DOPA and 5-hydroxy tryptophan (5-HT) as a major constituent with higher concentration in seeds. However, literature search revealed no scientific data on its anxiolytic activity. So the present study was designed to evaluate the anxiolytic activity of Mucuna pruriens in a murine model. Wistar albino rats were divided into five groups (n=6). Mucuna pruriens administered at doses of 250,500,750mg/kg/day orally, was compared with the standard drug Diazepam (1.0mg/kg/day, oral) fed for 14 days. Three pharmacologically validated models elevated plus maze, bright and dark arena and open field test were used.

Wagh J yoti G orakh, Dharmendra Ahuja, Banerjee A ngshu

Alprazolam (ALP) is benzodiazepine derivative which produce symptomatic relief of anxiety and tension state resulting from a stressful enviourment or emotional factors. The First method was based on simultaneous equation method. In the proposed simultaneous equation method, the signals were measured at 222.0 nm and 227.0 nm corresponding to the absorbance maxima of ALP and FLU in methanol. The method was validated statistically. Recovery study was performed to confirm the accuracy of the method. This method is suitable technique for the reliable analysis of commercial formulation containing combination of ALP and FLU. Simplicity, sensitivity and rapidity of simultaneous equation method render it suitable for routine analysis for ALP and FLU from their combination dosage forms. The Second method was based on absorbance ratio method (Q. analysis). The absorbance was measured at two-wave lengths 222.0 nm (max) of ALP and 227.0 nm, which is an isoabsorptive point, were found adequate for quantification. The method is validated statistically. The recovery more than 99% with low SD suggests the accuracy of the method. In addition, the above-proposed UV spectroscopic methods are simple, easy to apply, low cost, does not use polluting reagents and requires relatively inexpensive instruments.

Optimization of the In Vitro Transcorneal Release and the In Vivo IOP-Lowering Effects of Latanoprost Ophthalmic Gel Formulations Using Azone™ as a Penetration Enhancer and Carbopol-974® as a Mucoadhesive

Mohsen. Afouna, ashraf Naim

The objectives of this study were to maximize; a) the in vitro transcorneal release, b) the IOP-lowering effect and, c) the duration of action, of Latanoprost acid (LAT) ophthalmic gels. The in vitro transcorneal release of LAT from a 1st set of gel formulations that containing different concentrations of Azone™ (as enhancer) with fixed concentration of C-974® (as mucoadhesive) were studied. Formulation that showed greatest permeability parameters at lowest Azone™ concentration was selected for preparation of a 2nd set of ocular gels containing various C-974® concentrations. The in vitro transcorneal release was assessed, and the best C-974® concentration required for preparation of formulations that can be conceded as ideal ophthalmic LAT gels hve been pinpointed and scaled up for in vivo IOP-lowering efficacy study using TONO-PEN™ AVIA tonometer in rabbits for 4-consecutive days. Various test formulations have showed significant but varied augmentations in both, in vitro and in vivo results. Formulations (GAZ-4) & GC-4 have shown the highest therapeutic IOP lowering effects; i.e., (7.8±1.8), (6.5±2.1), respectively. Particularly noteworthy with both formulations the IOP base-line didn’t re-established after 24 hours, and their durations of action in the single-dose study were 47±2.25, and 48±1.5, respectively. The in vitro release, onset, magnitude & duration of action of action of LAT gels have been enhanced and extended for up to 2-day with two gel formulations. Nonetheless, the success in developing a novel ophthalmic formulation depended for great extent upon the crucial net outcomes of a very sensitive interplay/balance between the drug and additives.

Carbopol® and Chitosan Coated Nanoparticles with In-Situ Loaded Indomethacin

Velichka Andonova, George Georgiev, Vencislava Toncheva, Daniela Karashanova, Plamen Katsarov, Margarita Kassarova

Indomethacin-loaded nanoparticles (IMC-NPs) were obtained by emulsifier-free radical polymerization of vinyl acetate (VAc) in the presence of indomethacin (IMC) in the aqueous solution of Carbopol® (Cbp) or chitozan (CH). The purpose of this study was to investigate the influence of nature and quantity of the added to the reaction system polymer on IMC loading and its kinetic release properties in terms of the future development of topical ophthalmic formulations. CH was chosen as a cationic polysaccharide and Cbp as an anionic crosslinked polymer. TEM and DLS were used to observe the morphology and to determine the average particle size which was in the range of 178.20÷297.90 nm and the polydispersity index (PDI) which was within 0.149÷0.339. A monomodal particle size distribution (PSD) was observed for the CH-coated NPs and bimodal PSD was observed in the models, obtained in the presence of Cbp. FTIR analysis showed that the models were a result of interactions with hydrogen bonds. UV-spectroscopy was used for the determination of IMC inclusion and in vitro release characteristics. The results of release kinetic analyses showed that IMC was released from the investigated models following the first order. The polymer shell (Cbp or CH) around the pVAc–core had an impact on the rate and degree of the released drug.

NCE-9 Inhibits Protein Tyrosine Phosphatase Ptp1B and Prevents Hypertriglyceridemia and Hepatic Steatosis In Fructose Fed Rats

Chandrashekhar L Athare, Ghanshyam B Jadhav, Chandrashekhar D Upasani

Fructose consumption from sucrose and high-fructose corn syrup have Increased both plasma insulin and leptin act in the central nervous system in the long-term regulation of energy homeostasis. Because fructose does not stimulate insulin secretion from pancreatic β cells, the consumption of foods and beverages containing fructose produces smaller postprandial insulin excursions than does consumption of glucose-containing carbohydrate. Because leptin production is regulated by insulin responses to meals, fructose consumption also reduces circulating leptin concentrations. The combined effects of lowered circulating leptin and insulin in individuals who consume diets that are high in dietary fructose could therefore increase the likelihood of weight gain and its associated metabolic sequelae. In addition, fructose, compared with glucose, is preferentially metabolized to lipid in the liver. Fructose consumption induces insulin resistance, impaired glucose tolerance, hyper insulinemia, hyper triacylglycerolemia, and hypertension in animal models. The data in humans are less clear. Although there are existing data on the metabolic and endocrine effects of dietary fructose that suggest that increased consumption of fructose may be detrimental in terms of body weight and adiposity and the metabolic indexes associated with the insulin resistance syndrome, much more research is needed to fully understand the metabolic effect of dietary fructose in humans. We investigated the effects of NCE-9 on fructose-induced hypertriglyceridemia and liver steatosis in rats. NCE-9 reduced serum TG and VLDL levels and also improve glucose intolerance in fructose-fed rats. This PTP1B inhibitory property may be a promising therapeutic strategy for NCE-9 to treat fructose-induced hepatic steatosis.

Parth Patel, Priya Varshney, Megha Shah, Vijya Parmar

Two simple, accurate, precise, reproducible, requiring no prior separation and economical procedures for simultaneous estimation of difluprednate and moxifloxacin hydrochloride in combined dosage form have been developed. First method employs formation and solving of simultaneous equation using 241nm and 288 nm as two analytical wavelengths for both drugs in distilled water. The second method is a Q value analysis based on measurement of absorptivity at 241nm and 264nm (as an ISO-absorptive point). Difluprednate at their respective λmax 241 nm and 288 nm and at iso-absorptive point 264 nm shows linearity in a concentration range of 10-20 μg/mL and similarly moxifloxacin at their respective λmax 288 nm and 241 nm and at iso-absorptive point 264 nm shows linearity in a concentration range of 1-5 μg/mL. The results of the analysis have been validated statistically.

Vanitha Kalappan, Dhanapal Sakthisekaran, Aruldass Ilakkia, Kuppusamy Periyasamy, Kuppusamy Basker, Sundaramoorthy Selvaraj

Breast cancer is one of the most serious problems in oncology. It is a leading cause of death among women in many countries. Environmental factors, of either biological or chemical origin, may act as initiators and promoters of the carcinogenesis. Chemical carcinogens such as 7,12-dimethylbenz[a] anthracene [DMBA],benz[a]pyrene [BP], and N-nitroso-N-methylurea are commonly employed to initiate and promote neoplastic transformation in experimental animals. DMBA is well established as a highly potent carcinogen. Cancer chemoprevention is recognized as the most promising and novel approach to prevent, inhibit or reverse the carcinogenic processes by intervention with natural products or synthetic chemical substances. Taurine is a sulfur containing beta amino acid with a wide range of vital, biological functions, ranging modulation, cell membrane stabilization to bearing an antioxidant and scavenging agent. In from neuro the last decade it has been widely used in the field of oncology as a chemo protective agent against hepatocarcinogenesis and colon carcinogenesis. The aim of this study was to get insight into the process of chemo resistance acquisition for a better understanding of the breast cancer therapy. Therefore, the current study has been undertaken to examine the effect of taurine on DMBA induced breast cancer in rats. At the end of the experimental period, the homogenized breast tissue was investigated and recorded the body weight, tumor weight and antitumor activity of Taurine in the experimental rats. Overall, these results suggested that the taurine treatment provided antioxidant defense with strong chemopreventive activity against the genesis of DMBA-induced mammary carcinoma.

Nanosilver Fabrication Mediated by Exopolysaccharides from Pseudomonas fluorescens and Its Biological Activities

Abdul Razack Sirajunnisa, Duraiarasan Surendhiran

Synthesis of silver nanoparticle (SNP) has become an emerging trend in the field of nanotechnology. Here a greener method was approached to develop silver nanoparticles using extracted exopolysaccharides (EPS) from Pseudomonas fluorescens, a soil isolate from rhizosphere of the medicinal plant, Catharanthus roseus. The exopolysaccharide acted as a reducing and stabilizing agent in converting silver nitrate to silver nanoparticles. The fabricated SNPs were characterized by UV-Visible Spectroscopy, Scanning Electron Microscopy (SEM) and FT-IR Spectroscopy. The FT-IR analysis revealed that proteins present in the polysaccharide served as a capping agent. This simple process was carried out for 5 days at room temperature at optimum pH 7. The dried SNP sample is found to be stable for more than 6 months. The present work also focused on SNPs’ antimicrobial effect by agar well diffusion technique and antioxidant activity by DPPH method. The EPS reduced SNP was found to be more active against Gram negative than Gram positive and also worked in inhibiting Candida sp. DPPH radical scavenging effect of SNP was highly effective than standard at a maximum concentration of 1mg/ml. The investigation thus showed that EPS stabilized SNP could be employed in several pharmaceutical purposes.

This investigation deals with the formulation of sustained release niosome based system of silver sulfadiazine for the treatment of burn and thereby decreasing the dosing frequency which is really important for severe burn patient as every reapplication is very painful to them. In this investigation, the effect of different processing variables on entrapment efficiency of drug was evaluated. The vesicle size, photomicroscopy, in vitro release, scanning electron microscopy, stability and in vitro antimicrobial activity of niosomal vesicles formed were also characterized. Niosomes were developed from span 60 and cholesterol in different molar ratio by ether injection, thin film hydration and non solvent methods. Results indicated that the niosomes manufactured with span 60 and cholesterol in 50:50 molar ratio using 100mg of drug by thin film hydration method gives highest entrapment of 92.11%. The method of preparation and contents of cholesterol as well as drug were found to affect the entrapment. The optimized niosomal formulation exhibited significantly retarded in vitro release of 98.04% over 28 hours by a higuchi controlled mechanism. The in vitro antimicrobial study using Staphylococcus aureus revealed that niosomal formulation of silver sulfadiazine shows better zone of inhibition (18mm) in comparison to conventional dosage form (17mm). In conclusion this study showed that the niosomal formulation can be used as promising sustained release approach for the topical delivery of silver sulfadiazine in the treatment of burn.

Neha Sharma, Rahul Parakh, Dhruva Sharma, Preksha Sharma, Pooja Sharma, Neelima Sharma

The objective of this study was to assess the drug utilization pattern and cost analysis among the inpatients of medical intensive care unit (ICU) of NIMS hospital, Jaipur. After taking Ethics permission , records of 356 patients admitted in the medical ICU of a NIMS hospital were noted. Demographic profile, commonly prescribed drugs as per Anatomical Therapeutic Chemical Classification (ATC) and WHO core indicators were assessed from the records. Out of 356 inpatients, 224(62.9% ) were males . Most of the patients were in the age group of 61-70 for males 51-60 for females. Most commonly prescribed drugs were antibiotics followed by i.v. fluids. The average number of drugs per prescription was 11.99. Out of 4271 drugs prescribed, 1152(26.97%) were prescribed by generic names. Drugs on WHO EML were only 41% while that of NLEM 2011 were 68% . Drugs used as fixed dose combination were 19.26%. Average cost per prescription was INR 1975. Median length of stay was 6 days. Inspite of the fact that respiratory complications are one of the leading cause of death in critically ill patients and rational drug use plays a pivotal role in reverting the condition , there is a lack of pioneer drug utilization studies in this field. This study gives a message to adopt a cost effective and rational use of drug.

Xyloglucan Calcium Alginate (Ca) Coated Microbeads of Aceclofenac Sodium For Oral Controlled Drug Delivery

K.M. Manjanna, B. Shivakumar, K. S. Rajesh

The aceclofenac sodium loaded calcium alginate (CA) based microbeads prepared by ionotropic external gelation technique with calcium chloride as cross-linking agent. Calcium alginate microbeads represent a useful tool for oral sustained/ controlled drug delivery but show several problems, mainly related to the stability, and rapid drug release at higher pH that, in most cases, is too fast due to increase porosity. To overcome such inconveniences, which was to develop CA microbeads coated with xyloglucan (XG) as drug release modifier to improve stability and prolong the drug release. The mean particle sizes of drug-loaded microbeads were found to be in the range 476.45±12 to 765.10 ± 0.22. The drug entrapment efficiency was obtained in the range of 62.24±0.66 to 102.75 ± 0.87.The shape and surface characteristics were determined by scanning electron microscopy (SEM). No significant drug-polymer interactions, physical changes and crystallinity of the drug in the formulations were determined by FT-IR spectroscopy, differential scanning calorimetry (DSC) and X-ray powder diffraction [XPRD]. In-vitro drug release profiles of microbeads were pH dependent and were analyzed by different kinetic models. The mechanism of drug release from microbeads depends on swelling and erosion process resulting CA microbeads was diffusion controlled followed by First order kinetics and whereas CA microbeads coated with XG approaching to near Zero- order kinetics.

Pradip P. Deohate

A facile synthesis of 1,4-bis-(6-arylimino-[1,2,4]-triazolo-(3,4-b)-[1,3,4]-thiadiazol-3-yl)-benzenes have been carried out by reacting 1,4-bis-(4-amino-3-mercapto-4H-[1,2,4]-triazol-5-yl-benzene with N-aryl isocyanodichlorides followed by the basification with dilute ammonium hydroxide solution. 1,4-bis-(4-amino-3-mercapto-4H-[1,2,4]-triazol-5-yl-benzene was synthesized by the interaction of terephthalic acid dihydrazide with carbondisulphide and potassium hydroxide followed by the addition of hydrazine hydrate. The acetylation of bis-triazolo-dithiadiazines afforded di-acetyl derivatives. The structures of synthesized compounds have been established on the basis of chemical transformation, elemental analysis, equivalent weight determination and IR, 1H-NMR, mass spectral studies. The title compounds have been assayed for their antimicrobial activity against gram-positive as well as gram-negative micro-organisms.

Evaluation of Hepatoprotective Activity of Methanolic Extract of Justicia Beddomei (Clarke) Bennett Against INH and Rifampicin Induced Hepatotoxicity

Akash Marathakam, Kannappan N, Santhiagu A

The hepatoprotective effects of Methanolic Extract of Justicia Beddomei (MEJB)on Isoniazid and Rifampicin (INH and RIF) induced hepatotoxicity and the probable mechanism(s) involved in this protection were investigated in rats. Male wistar rats were divided in to five groups and used for the study. Hepatotoxicity was induced in animal models and was compared with the protective effect of standard drug Silymarin. In the present study it was noted that the administration of INH, Rifampicin decreased the level of total protein, albumin and increased the level of liver enzymes AST, ALT, ALP and TC. These parameters were brought back to the near normal level in control group treated with MEJB. The histopathological studies also revealed that treatment with Methanolic Extract of Justicia Beddomei (MEJB) showed a protection against injuries due to the effect of INH, Rifampicin. These results suggets that MEJB showed significant hepatoprotective activity against Isoniazid and Rifampicin induced hepatotoxicity and this might be due to the presence of flavanoids and phenolics. Further research is sought to explore the mechanism of action and phytoconstituents responsible for the pharmacological action.

Quality by Design Approach for Development of Verapamil Hydrochloride Floating Matrix Tablet.

YB Bansod, YN Dholariya, AE Shirsat, CL Bhingare, SA Shrivastav

Verapamil hydrochloride has a short half-life 2.8 to 7.4 hours, a narrow absorption window and is mainly absorbed in proximal areas of GIT. The present investigation aimed to formulate a floating drug delivery system of Verapamil Hydrochloride by Quality by design approach. In risk assessment, the effects of process and formulation variables on particle drug release and floating lag time were investigated. Design of experiments (DoE) and multivariate data analysis were used to identify important process and formulation parameters. A 22 factorial design in replicate was employed to produce controlled release floating tablet. The effect of critical formulation variables i.e. levels of HPMC K15M and gas generating agent (i. e. Sodium bicarbonate and citric acid) on % Drug release after 12 hr (% DRel12) and floating lag time (FLT) were analyzed. Verapamil HCl tablets were evaluated for hardness, friability, weight variation, drug content, floating behavior and drug release studies were conducted in 0.1 N HCl (pH 1.2) at 37 ± 0.5OC. The tablets showed acceptable physicochemical properties. The two independent variables studied exhibited a significant influence (P < 0.05) on % DR 12 Hr and FLT. Numerical and graphical optimization technique employing design space approach was used to develop a new formulation by setting constrains on the dependent and independent variables. The experimental values of % DR 12 Hr and FLT for optimized batch were found to be in close agreement with those predicted by mathematical model. Experimental values obtained from the optimized formulations were in both cases close to the predicted values, thus confirming the validity of the generated mathematical model. These results demonstrated the effectiveness of the proposed floating tablet, as well as the usefulness of the QbD approach for the development of Verapamil floating tablet with optimized properties.

In Vitro Hepatoprotective Activity of Limnanthemum Indicum [Whole Plant] Against Paracetamol Induced Toxicity Using Brl-3a Cell Line

Jyothi.Y, Sangeetha.D, Kiran Kumar.K

Liver plays a major role in detoxification. Any injury to it or impairment of its function may lead to many implications on one’s health. Management of liver diseases is still a challenge to modern medicine. The allopathic medicine has little to offer for the alleviation of hepatic ailments whereas the most important representatives are of phytoconstituents. The work presented in this paper is on plant Limnanthemum indicum which is reported that the whole plant is traditionally used as hepatoprotective. The study was aimed at evaluation of the hepatoprotective activity of the whole plant of Limnanthemum indicum on the BRL3A (Rat, Liver cell line) cell line. The various solvent extracts were tested for its inhibitory effect on BRL3A (Rat, Liver cell line) cell line. The percentage viability of the cell line was carried out. The cytotoxicity of Limnanthemum indicum on rat liver cell was evaluated by the MTT assay [(3-(4,5 dimethylthiazole –2 yl)-2,5 diphenyl tetrazolium bromide) assay]. The principle involved is the cleavage of tetrazolium salt MTT into a blue coloured derivative by living cells which contains mitochondrial enzyme succinate dehydrogenase However, the information available on the pharmacological activity of the plant is very limited. Hence, it was proposed to carry out a preliminary in vitro analysis of the hepato protective activity of the plant. Out of the various extracts evaluated, ethanolic extract of Limnanthemum indicum gave promising results.

Determination of three dimensional structure of scaA protein, a virulence factor of Streptococcus gordonii by homology modelling and design of inhibitors for scaA protein

Kannan I, Gomathi. GD, Sambandam Cecilia, Jayalakshmi M, Premavathy RK, Shantha S

Streptococcus gordonii are one among the early colonisers of tooth surfaces of humans and are present in coronal plaque, gingival crevices and buccal and pharyngeal mucosal surfaces. One of the main virulence factor that is involved in S. gordonii adhesion and coaggregation is ScaA protein. Inactivation of scaA genes resulted in both impaired growth of cells and inhibition of Mn2+ intake. Thus the inhibitors of ScaA protein can act as an effective drug against S. gordonii especially in the prevention and treatment of infective endocarditis and dental caries. The three dimensional structure of ScaA protein is predicted by homology modelling. It is the method to determine 3D structure of protein with the help of 3D structure of homologous proteins. Softwares used are Modeller 9.11 and Easy modeller 2.0 GUI. A total of 500 ligands in 2D format were derived from myricetin with the help of software ACD chemsketch. Rapid virtual screenings of these compounds were performed in the docking tool iGEMDOCK v2.0. Based on the binding energy a total of three ligands were selected for the further study. Three ligands thus generated possessed very good docking energy. Thus three ligands with good inhibitory properties were generated among which 5-[3,4-dihydroxy-6-(pyridin-2-yl)-8aH-chromen-2-yl]benzene-1,2,3-triol, a novel compound is found to be very excellent drug candidate based on the molecular docking studies and its ADME properties.

Chittanahalli N. Sudhamani, Halehatty S. Bhojya Naik, Kalligundi R. Sangeetha Gowda1 and M. Giridhar

Fe(II) complexes [Fe(mqs)(B)2](PF6)(1)-(3) of 2-thiol 4-methylquinoline and phenanthroline bases (B), viz 1,10-Phenanthroline (phen in 1), Dipyrido[3,2-d:2',3'-f]quinoxaline (dpq in 2) and Dipyrido[3,2-a:2′,3′-c]phenazine (dppz in 3) have been prepared and characterized. The DNA-binding behaviors of these three complexes were investigated by absorption spectra, viscosity measurements and thermal denaturation studies. The DNA-binding constants for complexes 1, 2 and 3 were determined to 2.4 x104, 1.3 x 105 and 4.2 x105 M-1, respectively. The experimental results suggest that these complexes interact with DNA through groove binding mode. The photo induced cleavage studies shows that the complexes possess photonuclease property against pUC19 DNA under UV–Visible irradiation via a mechanistic pathway involving formation of singlet oxygen as the reactive species. Antibacterial PDT for E. coli strain, the control group showed a significantly higher (p0.05) in the CFU counts. The complex (3)/Light group presented a significant decrease in the CFU counts (p

Effect of Milnacipran and Atorvastatin Alone and In Combination In Rodent Model of Inflammatory Pain

Sachin Bansal, Savithiri Shivakumar, Manoj Ande, Pratima Srivastava

5-Hydroxytryptamine (serotonin) (5-HT) and norepinephrine (NE) are implicated in modulating descending inhibitory pain pathways in the central nervous system. Milnacipran (MLN) is a selective and potent dual 5-HT and NE reuptake inhibitor (SNRI). In the present study, the effects of HMG-CoA reductase inhibitor atorvastatin (ATR) on antidepressant- induced anti-nociception have been investigated. Anti-nociceptive effects were evaluated using formalin test in rats after administration of atorvastatin and milnacipran alone as well as in combination. Fifty microlitre of 2.5% formalin solution was injected subcutaneously into the plantar surface of the right hind paw and nociceptive behavior was observed up to 45 min in the blocks of 5 min. Milnacipran induced a dose-dependent anti-nociception in the first phase as well as in the second phase of the formalin test at the dose levels of 10, 20, 40 and 60 mg/kg, p.o.. Milnacipran significantly attenuated the duration of licking and licking frequency both in second phase. Atorvastatin (1, 5, 10 and 20 mg/kg, p.o.) did not inhibit the nociceptive behavior of formalin significantly when treated alone. A combination of sub-therapeutic doses of the milnacipran (20 and 40 mg/kg, p.o.) with atorvastatin (10 and 20 mg/kg, p.o.) potentiate anti-nociception induced by antidepressant significantly. It is concluded that the atorvastatin modulate the antidepressant-induced anti-nociception in formalin induced inflammatory pain model. However, studies in chronic models of neuropathic pain are required to evaluate the efficacy of milnacipran and atorvastatin combination in rats.

Chitrarekha Girish Kulkarni, Vaibhav Sampatrao Madane, Shital Tanaji Jadhav

Modern synthetic medicines are highly effective in curing various diseases, but many of them show significant side effects. A large number of Indian herbs are claimed to possess anthelmintic properties. However, systematic study and standardization of activities are lacking. The present investigations are undertaken to evaluate and standardize anthelmintic activities of common Indian herbs. Aqueous and ethanolic extracts of Plumbago zeylanica, Myristica fragrance and Saraca asoca are studied with respect to in vitro anthelmintic activity against Eisenia foetida and Pheretima posthuma. Results are expressed in terms of time for paralysis and time for death. Albendazole (20mg/ml) is used as a reference standard. Ethanolic extract of Saraca asoca (50 mg/ml) proved to be the best death inducer against Eisenia foetida, whereas ethanolic extract of Plumbago zeylanica at concentration 50mg/ml showed highest anthelmintic activity against Pheretima posthuma.

Exposures of Long Intake of Aspartame on Free Radical Scavenging Enzymes in Blood cells and Neutrophil Functions of immunized wistar albino rats.

Arbind Kumar Choudhary, Rathinasamy Sheela Devi

The artificial dipeptide sweetener aspartame [APM; L- aspartyl-L- phenylalanine methyl ester] is present in many products especially unsweetened and sugar products. These products are frequently utilized by people trying to lose weight or patients with diabetes. Concern relating to the possible adverse effect has been raised due to aspartames metabolic components. Aspartame is rapidly and completely metabolized in humans and experimental animals to aspartic acid (40%), phenylalanine (50%) and methanol (10%). Methanol, a toxic metabolite is primarily metabolized by oxidation to formaldehyde and then to formate these processes are accompanied by the formation of superoxide anion and hydrogen peroxide. This study focus is to understand whether the oral administration of aspartame (40 mg/kg b.w) for 90 days, have any effect on membrane bound ATPases in RBC, antioxidant status in blood cell and neutrophil function of rats. To mimic human methanol metabolism, folate deficient rats were used. After 90 days of aspartame administration, shows a significant change in membrane bound ATPases, antioxidant level and immune response. This study concludes that oral administration of aspartame (40mg/kg b.w) for longer duration may cause oxidative stress in blood cell and altered the neutrophil function

Kotha Arun Kumar, Vemuri Pavan Kumar, Sumanth T N

Medicinal plants and their secondary metabolites have been used since last few centuries as remedies to treat diseases and disorders. As per WHO report (1993), 80% of world population continues to depend on medicine isolated from medicinal plants. Presently there is an increasing interest in herbal medicine related to isolation, characterization and pharmacological screening of extracts obtained from medicinal plants. The ethanolic extract of Leucas indica var. martinicensis was studied for preliminary phytochemical screening and anthelmintic activity at various concentrations (i.e., 10mg/ml, 25mg/ml, 50mg/ml, 100mg/ml) by using adult Indian earth worm, pheretima posthuma from in nalgonda region. Phytochemical Screening revealed the presence of Alkaloids, carbohydrates, and saponins. The mean paralysis time and mean death time for each sample was calculated and compared with the Albendazole which is taken as standard. The result was found that Leucas indica var. martinicensis had an anthelmintic activity which was greater than standard Albendazole.

The prepared copolymer solution is dropped in to 2% CaCl2. The beads are hardened by cross linking with a common cross-linking agent, glutaraldehyde. The beads are characterized by Fourier transform infra-red spectroscopy and scanning electron microscopy. Additionally quality control tests such as swelling index, bead water uptake, entrapment efficiency and drug release studies are performed. The extent of cross-linking is studied in terms of the size and release characteristics of the beads. Most of the formulations indicated erosion based release pattern. The size of the beads ranged from 250 to 400 µm. The entrapment efficiency of the formulation ranged from 73.6% to 94.50%.

Synthesis, Antibacterial Activity and Preliminary QSAR Studies of Diaryl Sulfones

Ashwini Wani, Supriya Mahajan

Sulfones are known to possess various biological activities. Their great potential as bioactive compounds, combined with the easy method of synthesis, make this class a strong candidate for the production of medicines economically. This article deals with the synthesis of a series of ten diaryl sulfones, their antibacterial activity, individually, synergistic antibacterial activity with trimethoprim against E. coli and preliminary QSAR studies. The antibacterial activity was performed by agar diffusion method, against Gram positive and Gram negative bacteria. Few derivatives exhibited antibacterial activity comparable to or better than the standard, sulphamethoxazole, against Gram negative organisms (E. coli and S. dysentrae). Sulfones being folic acid inhibitors, their synergistic effect was checked with trimethoprim on E. coli. Most of the compounds exhibited synergistic effect with trimethoprim, which was better than the combination of trimethoprim and sulfamethoxazole (1:5). Quantitative structure activity relationships studies were performed by multiple linear regression analysis. The antibacterial activity of sulfones was found to correlate well with their dipole moment and ionization potential.

An Efficient RP-HPLC Method for the Simultaneous Quantitative Determination of Artemether and Lumefantrine In Human Plasma by using Dad Detection

Vikas Payal, Animesh Kumar, Navdeep Kaur Gill, Dheeraj Kumar, Ganti S Sarma

Artemether-lumefantrine (ART-LUME) off late has become the first-line treatment for uncomplicated malaria in many Sub-Saharan Africa, Asia and America. Vigorous monitoring of the therapeutic efficacy of this treatment is needed. This requires high-quality studies following standard protocols; ideally, such studies should incorporate measurement of drug levels in human plasma in biological matrices. A specific and reliable isocratic mode RP-HPLC method has been developed and validated for simultaneous determination of artemether (ART) in combination with lumefantrine (LUME) in human plasma using diode array detector (DAD) at 238 nm. The analyte was separated on NUCLEOSIC-CN Cyano coloumn (150 mm × 4.6 mm, particle size 5 μm) using a mobile phase consisting of acetonitrile and acidic buffer (adjusted to pH 2.5 with H3PO4 – 2 %) in the ratio of 37: 63 v/v and flow rate was 1 ml/min. The method is linear over a range of 100-1600 µg/ml (r2 ≥ 0.999) and 1-16µg/ml (r2 ≥0.998) for the assay of ART and LUME respectively. Itraconazole (ITZ) (10µg/ml) was used as internal standard. The retention times of ART and LUME was found to be 4.3 min and 14.3 respectively. Mean extraction recovery for ART and LUME were 87.3 % and 89.1 %, respectively. Inter and intraday coefficients of variation for ART and LUME were ≤ 10%. The lower limits of quantification for ART and LUME were 0.22 and 0.66 μg/ml, respectively. The results of the study showed that the proposed RP-HPLC validated method described is efficient and has the necessary accuracy and precision for the rapid quantitative simultaneous determination of ART and LUME in human plasma and is thus highly suitable for use in pharmacokinetic /bioavailability/bioequivalence studies in healthy human subjects.

Effect of the probiotic yeast Saccharomyces boulardii on Giardia lamblia and electrolyte ratio in mice.

Sabaa Tahir Mohamed, Hamzia Ali Ajah

The principal objective for our study was to evaluate the efficacy of Saccharomyces boulardii against Giardia lamblia infection and investigated the mechanism of this anti diarrheal effect on electrolyte (sodium,potassium and chloride) changes compared with metronidazole by using mice models.A single oral dose of S.boulardii of up to 5 x106cfu/0.1 of viable cells reduced parasite appear in feces and disappear completely at the 7th day compared with metronidazole the cysts parasite continued till 8th day. The yeast also caused increased potassium and sodium while decrease chloride level in serum. The histo morphological study findings showed in the group which was given S. boulardii the majority of intestinal villi return to normal shape. These finding indicated that S.boulardii may be effective in treating giardiasis also has specific effects on electrolyte secretary response.
