Micro needles: A Novel Trend for Transdermal Delivery technology

Patel Brijesh P, Priya Raina, Shah Devarshi, Parikh RK

The transdermal route of drug delivery overcomes many of the limitations associated with the more common oral and parenteral routes. Micro needles are micronized needles made from biodegradable polymer, ranging from 25 to 2000 µm in height, made up of variety of the material and shape. Advantages associated with micro needles are ease of use, controlled drug delivery, avoidance of first pass metabolism and lack of pain. However, transdermal drug delivery is limited due to the barrier provided by our skin known as stratum corneum which is the outermost non-viable layer of the epidermis. Microneedles were developed with the advantage that these can deliver the drug in a non- invasive painless manner and along with this overcome stratum corneum. The upper layer of the skin is penetrated by the microneedles without reaching the nerve, there by delivering drug transdermally in a painless manner. The present poster discusses the various fabrication techniques of micro needles using microelectromechanical system the design, material consideration and the application of micro needles in transdermal drug delivery system.

Novel Technologies Mark the Future of Insulin

Priya Raina, Patel Brijesh P, Shah Devarshi, Parikh RK

Diabetes mellitus  is a chronic disease that is characterized by inadequate pancreatic insulin secretion or poor insulin directed mobilization of glucose by target cells. Population affected with diabetes has increased from 108 million in 1980 to 422 million till date. So, it is clearly evident that the rate is alarming and diabetes has now become a global problem. Diabetes is seventh leading cause of death globally. Insulin therapy in diabetes is the commonest and the most effective therapy. Conventional methods like subcutaneous or the oral route are having several shortcomings like the pain and invasion associated with injections, oral degradation of insulin, infection, etc. Among all the demerits hypoglycemia is the major issue especially nocturnal hypoglycemia as the patient cannot monitor the level of glucose at night. To overcome these detriments there is a need for insulin delivery through novel technologies.  Many novel technologies have been proposed like the painless smart patch, Clicksoft microinjection device, pens, pumps, modified oral delivery oral delivery, inhaled insulin, etc. for the delivery of insulin.  Many other novel devices and routes are being developed. This review discusses the glimpse of these novel technologies with their pros and cons.

An Overview On Alzheimer’s Disease: Causes, Symptoms, And Its Treatment

Ravikrindi Sridhar, I. Lakshmi anusha, M.Aashritha, K.Teja, K.N.S.Karthik

Alzheimer’s disease is a degenerative brain disease and the most common cause of dementia. Dementia is also caused by other diseases and conditions. it is characterized by decline in memory , language , problem solving and other cognitive skills that effects a person’s ability to perform everyday activities. This decline occurs because nerve cells (neurons) in parts of the brain involved in cognitive function have been damaged and no longer function normally , In Alzheimer’s neuronal damage eventually affects parts of the brain that enable a person to carry out basic bodily functions such as walking and swallowing . People in the final stages of the disease are bed-bound and required around  the-clock care .Alzheimer’s disease is ultimately fatal.1

Emulgel- Novel Strategy for Delivery of Hydrophobic Drugs

Prashant B. Dalvi, Ramesh D.Bhusal

When gels and emulsions are used in combined form the dosage form are referred as emulgel. Also there has been incredible interest for the utilization of novel polymers and drug molecules. A one of the feature of topical drug delivery is the immediate availability of the skin as  target organ for diagnosis and treatment. Among the different group of semisolid planning, the utilization of gel has extended both in cosmetics and in the pharmaceuticals. Although Gel has many advantages, there is many limitation in delivery of hydrophobic drugs, so to overcome this limitation an emulsion base novel approach is being most used. That is emugel system used so that even a hydrophobic moiety can enjoy the unique properties of gels and having characteristics of dual control release i.e. emulsion as well as gel. The formulation is prepared by various polymer which behave as an emulsifer and thickening agent because of gelling capacity of these compounds give rise to stable emulsions and creams by diminishing surface and interfacial pressure while in the meantime expanding the thickness of the aqueous phase. In order to understand the potential of emulgel as delivery vehicles, this review gives an overview of the ideal properties, formation, and characterization of emulgels. So this can be use as analgesics and antifungal drugs, as superior topical drug delivery systems over present conventional systems available in market.

A Comprehensive Review on Controversies In Immunisation Vaccination

Neethu J, Clinton Baby, Avinash.M, Akhil Babu

Childhood vaccination is our primary method to promote public health. Concerns and controversies about vaccination and vaccine safety had led some parents to decline recommended vaccination of their children 4.This study systematically reviewed the literatures on controversies in childhood immunization 2. The objective of our study is to assess the controversies and risk benefit ratio of vaccination from the available data 4.  Data resources were collected from existing articles, electronic citations and existing reviews. Supportive to some personal beliefs of parents and their trust to other systems of medicine like homoeopathy there are reports of ill effects of vaccines(poliomyelitis by oral polio vaccine, encephalitis by measles vaccine) . Some other disorders had also been reported with or without evidence. But most of the studies concludes that the benefits of immunization far outweighs risk. The risk of many diseases and mortality rate had decreased in present era due to vaccination. A dramatic example of the benefits generated by vaccination is evident in the context of diphtheria. During the 1930s an average of 61,000 cases of the disease were experienced each year in England and Wales, resulting in the deaths of approximately 3,000 individuals 3 .Studies shows that after taking immunisation ,during the first three years and nine months of the 1980s there were 15 notified cases of diphtheria and only one death. Poliomyelitis routine immunisation for infants has been pursued in England and in the 1980s only 10 cases of acute poliomyelitis have been notified to the authorities from an average of 2827 notified cases in 1956.  Educating parents about vaccine preventable diseases as well as the vaccines may be one of the ways to impart the importance of vaccines to the health of their child 1.

2D QSAR Study For 1-Aryloxy-3-(N4-Piperazinyl) Propan-2-OLS

Ganesh B.Gajeli, Sanjay.B.Wagh

Last three decades enormous work has been carried out on computational chemistry. The projects given for discovery of New Chemical Entities by these methods and gets a safe, potent drug molecule. However, the commercial output for the pharmaceutical company with these methodologies is negligible. Most of the drugs discovered in medicinal chemistry are accidentally. Thus synthesis of focused compound libraries and their pharmacological screening by efficient methods becomes powerful tool for drug discovery. But some additional points are required to move towards aryloxypropanolamines As 1-Aryloxy-3-(N4-substituted piperazinyl) propan-2 OLS (aryloxypropanolamines) shows β-adrenergic receptor antagonist activity (β-blockers), these chemical entities are applicable in management of various diseases due to their therapeutic effects. The main clinical indications of β-blockers are in the area of cardiovascular diseases, such as hypertension, angina pectoris, myocardial infarction and cardiac arrhythmias1-4. However, some β-blockers readily access the brain because of their lipophilicity and can influence some central nervous system functions. Therefore, Propranolol has been used for the treatment of anxiety syndromes, prophylaxis of migraine headaches, schizophrenia, alcohol withdrawals and tremors5-8. Looking at the biological profile of various aryloxypropanolamines (also Enciprazine) molecule, synthesis of various derivatives of Enciprazine having different aryloxy moiety and amine moiety (by taking different N- alkyl/aryl substituted piperazine) was planned to get safe, potent or new activity molecules.

Suresh Kumar Raju Vidyadharani, Ravoori Sreenivasulu

A rapid, sensitive, precise, and accurate HPLC method coupled with a photodiode array detector was developed, optimized, and validated for the estimation of everolimus in bulk and tablet dosage forms. The chromatographic separation was achieved using a kromosil C8 column (200 mm × 4.6 mm i.d., 5 μm particle size) at 30°C temperature. The isocratic mobile phase consisted of 0.1M dipotassium hydrogen phosphate and methanol (60:40, v/v). The mobile phase was delivered at 1.0 ml/min and the analyte was monitored at 277 nm. The method was successfully validated in accordance to International Conference on Harmonization. The retention time of everolimus was found to be 3.496 min, and the calibration curve was linear in the concentration range of 50-150 μg/ml (R2 = 0.9992). The limit of detection and the limit of quantitation were found to be 0.109 μg/ml and 0.364 μg/ml, respectively.  The proposed method is accurate (percent recoveries were in the range of 99.56-100.09%) and precise (percent relative standard deviation - 0.047 %). No chromatographic interferences from the tablet excipients and components of mobile phase were found. The proposed method was found to be suitable for the quantitative determination of everolimus in tablet dosage forms.

The Mutagenic Effect of the Diethyl Sulphate and Dimethyl Sulphate for in vitro regeneration to okra (Abelmoschus Esculentus l. Moench)

Elena Bonciu

The creation of genetic variability through the use of chemical mutagenic factors which increase the frequency of in vitro mutations to okra is not very frequently mentioned in scientific literature. This is why we have undertaken this study on the assessment of the in vitro regeneration in okra subject to the action of two chemical mutagens: Diethyl sulphate and Dimethyl sulphate. With a 0.1 ppm concentration, Diethyl sulphate had a low stimulative effect on the regeneration of okra in vitro, while this mutagen inhibited in vitro regeneration to some extent for 0.2 ppm and 2 ppm concentrations. On the other hand, the chemical mutagen Dimethyl sulphate resulted in an obvious decrease in the percentage of regenerated neoplantlet for all the three concentrations, but for the 2 ppm concentration in particular, and this negative effect was also seen in the case of the multiplication rate, through subculture. Moreover, the strongly mutagenic action of Dimethyl sulphate was also suggested by the appearance of a larger number of chromosome aberrations in the meristematic tissues of okra grown in vitro under the influence of this chemical mutagen, compared to Diethyl sulphate. Thus, in the case of okra culture in vitro, Dimethyl sulphate is a stronger mutagen compared to Diethyl sulphate and, hence, this one can be used to induce mutagenicity to okra, and any mutations may be speculated for the modern and quick improvement of this significant species, both at a nutritional and therapeutic level.

Floating matrix tablets were prepared by  wet granulation technique using  varying concentrations of different grades of gel forming polymers like HPMC K100, HPMC K15, HPMC K4M with sodium bicarbonate as gas generating agent and evaluated for the physico-chemical parameters, floating lag time, total floating time, in vitro dissolution study and swelling studies. The physico-chemical properties of all the formulations were found to be within the prescribed official limits. FTIR study reveals that there was no interaction between drug and excipients. The amount of drug released from various FDDS formulations was found to be in the order of HPMC K100M > HPMC K15M > HPMC K4M. From among all the formulations, the formulation LF-9 with 30% HPMC K15M showed the best result in terms of the required lag time (82±5 sec) and floating duration of 12 h and releasing 99.5% of the drug in 12 h and is considered as the ideal formulation. The dosage form can control the release, avoid dose dumping and extend the duration of action of a drug with prolonged floating time.

Novel Synthetic Unnatural β3 aminoacids via acid hydrolysis of diazepinones as Synthons for Antibiotics

Muniraj Krishnaveni Yuvapriya*1.Periasamy Selvakumar1. Chandrasekar Balachandran

A convenient two-step method for the preparation of β3-amino acids is described.  This paper describes an efficient and straightforward two-step synthetic sequence leading in excellent yields to a relatively inaccessible lipophilic β3-amino acids with antimicrobial potential  from easily available starting materials. Schmidt reaction of substituted piperidin-4-ones with HN3 generated in situ afforded the corresponding diazapinones. Acid hydrolysis of chosen diazapinones yielded β3-amino acids. Selective cleavage of only the lactam bond is achieved using 4N HCl-MeOH (1:1) mixture   leading to the formation of N-alkyl β3-amino acids in quantitative yields. synthesized  aminoacids are subjected to antimicrobial activity for gram positive, gram negative bacteria, fungi. compounds  3e & 3h  possess excellent antimicrobial and antifungal activity comparable to standard streptomycin and ketoconazole. Therefore obtained β3-amino acids serves as a scaffold for  synthetic  antibiotics  as they have desired structural moieties necessary for antibiotic action. Further refinement of  the β3-amino acids  using  either conjugation or structural modification or incorporation of these aminoacids into synthetic peptides would bring about excellent antimicrobial activity.

Development and validation of a method for densitometric analysis of umbelliferone, β-sitosterol and methoxsalen in polyherbal formulation

Deepa Iyer, U. K. Patil

Herbal medicines are generally available as a mixture of more than one plant constituent. It is important to quantify the maximum possible number of markers in such herbal formulations by which the quality of the formulations may be assessed. TLC densitometric methods were developed using High performance thin layer chromatography for the quantification of the three marker compounds, umbelliferone, β-sitosterol and methoxsalen, from the polyherbal tablet formulation. Solvent systems were optimized to achieve best resolution of the marker compounds from the other components of the sample.  From the various solvent systems tried, the one containing toluene: ethyl acetate: methanol: formic acid (3: 3: 0.2: 0.8) gave best resolution of umbelliferone (Rf=0.35), β-sitosterol (Rf=0.47) and methoxsalen (Rf=0.6) in the presence of the other compounds in the polyherbal tablet sample and enabled the quantification of the marker compounds. The methods were validated in terms of precision, repeatability and accuracy. The method was found to be suitable for the quantification of these marker compounds in polyherbal formulation.

Designing of Triazolethione Nucleus Derivatives as Gamma-Amino butyric Acid (GABA) Activators Using Pharmacophore Modeling, 2D-QSAR, and Molecular Docking Approach

Meena K Yadav, Laxmi Tripathi, Diptendu Goswami

New Chemical Entities (NCEs) were designed using information from pharmacophore profile of known anticonvulsants. Binding affinities of designed NCEs were studied on gamma-aminobutyric acid (GABA-alpha) using docking studies. Two Dimensional (2D) Quantitative Structure–Activity Relationship (QSAR) studies were performed for correlating the chemical composition of triazolethione analogs and estimation of their anticonvulsant activity using Multiple Linear Regression (MLR) Analysis.  ADMET properties were also predicted. These four basic strategies (pharmacophore mapping, QSAR, docking & ADMET screening) were implemented to evaluate the performance of derivatives. Although predicted Ki through QSAR model showed significant mild activity for GABA. Conclusively compounds, 2, 6, 7, 8, 9, 10, 11, and 20 were observed to be most feasible to activate GABA for anticonvulsant activity.

QHPTLC Method for the Estimation of Santalum Album In Padoladi Ghritham- A Polyherbal Ayurvedic Formulation

P.N.Presannakumaran, P.Jayasekhar

A Quantitative High Performance Thin Layer Chromatography (QHPTLC) method was developed for the estimation of ‘Candana’ (Santalum album), one of the herbal ingredients present in the Ayurvedic polyherbal formulation ‘Padoladi Ghritham’. For this, both the methanol extracts of ‘Candana’ crude drug and Padoladi Ghritham were run using a mobile phase Chloroform : Isopropyl alcohol : Toluene (8:1:1, v/v/v) on a silica G 60 F254 stationary phase. Methanol extract of Candana  gave a spot with Rf value of 0.76. The methanol extract of Padoladi Ghritham also gave a spot with Rf value of 0.76. The chemical equivalency of these two spots was revealed by the same pattern of the UV spectrum with a λmax of 290 nm. Then the estimation was done graphically by preparing Quarter Standard, Half Standard, Normal Standard, and Double Standard of the formulation. A calibration plot was drawn between the concentration of standards and peak area of the reference spots. The concentration of Candana in the samples was found from the corresponding AUC obtained for the reference peak of the samples. A regression coefficient of 0.989 was obtained. The developed QHPTLC method is a simple and accurate one and can be used as a tool for the quantification of each ingredient in a polyherbal formulation.

An Overview of Some Sudanese Medicinal Plants having or Expected to have a Potential Antileishmanial Activity

Ahmed A. M. Ali, Mona S. Mohammed, Wadah J. A. Osman, Ahmed M. Musa

Infections caused by protozoa of the genus Leishmania are a major worldwide health problem with high morbidity and mortality in developing countries especially Sudan. The incidence of the disease has amplified since the emergence of AIDS. Since the discovery of the first drugs for Leishmaniasis treatment (i.e., pentavalent antimonials), up to now the search for substances with antileishmanial activity, without toxic effects, and able to overcome the emergence of drug-resistant strains still remains as the current goal. Moreover, in the absence of a vaccine there is a crucial need for effective drugs to replace/supplement those in current use. The plant kingdom is undeniably treasured as a source of new medicinal agents.   A thorough review of the literature on Sudanese plant extracts of natural origin either showing antileishmanial activity or expected to have, depending on the phytochemical screening is presented in this article. The review include 12 plants, their geographical distribution, the parts utilized, the type of extract, and the organism tested. The level of activity exhibited by the extracts depended largely on the type of solvent used for the extraction and the plant part used. Tannins demonstrated to be the key element of the antileishmanial properties and it is highlighted as potential source through the search for new Sudanese antileishmanial medicinal plants. The array of Sudanese medicinal plants that have demonstrated antileishmanial activity suggests that the hope to discover novel antileishmanial drugs is high.

Design and Evaluation of Tacrolimus by Using Liquisolid Technology

Chitta.Venkateswararao, J.Venkata Suresh, J. Praveen Kumar, G.Nagarjuna Reddy

Liquisolid technique is a new approach for delivery of drugs through oral cavity. This technique is suitable for poorly or water insoluble drugs and also for immediate or sustained release formulations. The technique is based upon the admixture of drug loaded solutions or liquid drug with appropriate carrier and coating materials to convert into acceptably flowing and compressible powder. The selection of non-toxic hydrophilic solvent, carrier, coating excipients and its ratios are independent of the individual chemical entities. Indirectly its leads to enhancement of bioavailibity. Liquisolid tablet of drug Tacrolimus were prepared by using PG, PEG 200, PEG 400, glycerin, Tween 80 and Span 80, as non volatile liquid vehicle, respectively. Tacrolimus is an immunosuppressive drug, which have poor water solubility and low bioavailability, so it is suitable for liquisolid technique. Also Tacrolimus is having daily dose 5-10 mg once a daily. FTIR and DSC studies reveal that there was no possible interaction between drug and tablet excipients. All the formulation was evaluated for disintegration time, hardness and friability time, in-vitro dissolution study.

Antidiabetic Activity of Gnetum Gnemon Fruits Against Type 2 Diabetes

Roslizam Binti Said, J Anbu Jeba Sunilson, Azian Abd Latiff, K Anandarajagopal

Type 2 diabetes occurs when the body becomes resistant to insulin or doesn't make enough insulin. The major treatment approach for diabetes is the use of synthetic drugs and insulin. However the side effects associated with the use of synthetic agents attracts the attention of drug discovery professionals to search an effective treatment using natural products. Malaysian plants and herbs have been used as medicinal agents and studies have proved their significance in the treatment of diabetes.  As the fruits of Gnetum gnemon (family: Gnetacea) locally known as melinjo are traditionally used to control diabetes by Malaysian and Indonesian tribes, the present study was aimed to evaluate the folklore claim about G. gnemon fruits to treat diabetes. Hexane extract (GGHE), chloroform extract (GGCE), ethanol extract (GGEE) and water extract (GGWE) were obtained by successive extraction using soxhlet extractor. The preliminary phytochemical analysis was carried out to perceive phytoconstituents in G. gnemon extracts. Diabetes was induced in albino rats by single dose of streptozotocin (60 mg/kg b.wt. i.p.) followed by nicotinamide (120 mg/kg b.wt. i.p.). Streptozotocin-induced diabetic rats were separately treated with GGHE, GGCE, GGEE and GGWE at dose of 400 mg/kg b.wt. and standard drug, glibenclamide (10mg/kg) respectively by oral administration for 14 days and antidiabetic potential of the extracts were assessed. Prelimary phytochemical screening showed the presence of flavonoids, terpenoids, phenolic compounds and tannins. Oral administration of diabetic rats exhibited significant (P
