Management of co- morbid depression in Diabetic patients : A Review

Aswathy Vijayan, Roshin Elizebeth Mathew, Mamen Alex, Veena Vijayan.G

Depression is commonly found as a co-morbid condition in diabetes. The relationship between the diabetes and depression is bidirectional. Coexistence of diabetes and depression is associated with poor symptom control, increased suffering, health care expenditure, disability, decreased quality of life and greater risk of death. Depression in diabetes is under diagnosed and undertreated. Depression adversely effect on both psychological well being and diabetic outcomes. Management of depression in diabetes should be directed toward improving psychological and medical outcomes, and quality of life. Pharmacologic and psychotherapeutic interventions shown to be effective in the management of depression in diabetes, which improve the glycaemic control and reduce the risk of short term complications. Selective serotonin reuptake inhibitors(SSRI), Serotonin norepinephrine reuptake inhibitors, and atypical antidepressants (eg. Buproprion) are preferred pharmacologic interventions for patients with diabetes and depression.

Approaches and advances in transdermal delivery of insulin -A Review

Jigyasa vindru, Aravind Ram AS, D. V. Gowda, Avinash S, Hamsika M, and Atul Srivastava

Even today the most preferred delivery of drugs is still through oral route but because of some inherited limitations with this route, various other routes have been explored including transdermal. Delivery and complete absorption of the drugs is the major concern these days due to various reasons including poor solubility and incomplete bioavailability, this could be due to incomplete presystemic absorption or presystemic degradation. Transdermal drug delivery system is the method by which the drug absorption occurs through the skin primarily for its systemic effect. It provides better therapeutic efficacy and safety for the administration of insulin. Most of the oral anti-diabetic drug exhibit low bioavailability and hence a poor patient compliance. Hence, it can be used as better site for delivery of numerous drugs including proteins and peptides such as insulin.

Type 2 Diabetes Mellitus and Metabolic Syndrome

Dhanya Hariharan, Shibina Shan

Metabolic syndrome is a constellation of interrelated cardio-metabolic risk factors that include Central Obesity, Hyperglycemia, Hypertension and Dyslipidemia. It has been estimated that about 1 in 5 (20.4%) adults in the U.S. have high blood pressure, it is very crucial to evaluate the serious health problems, level of awareness and knowledge about conditions relevant to metabolic disorders. Metabolic syndrome is caused not by genetic defects alone; in most cases, genetic factors predispose a person to a disease, while lifestyle factors determine whether (and when) the disease will develop. Several studies have demonstrated clearly the importance of dietary factors and physical activity level in the development of the metabolic syndrome. Given the same dietary and lifestyle factors, some individuals may be more prone to type 2 diabetes than others because of different genetic backgrounds. At a public health level, more attention must be given to modification of lifestyles of the general public to reduce risk of obesity and T2DM and to increase physical activity. At a clinical level, individual patients with increased metabolic risk need to be identified so that their multiple risk factors can be reduced. Considering the long asymptomatic period often preceding the manifestation of T2DM and CVD, early diagnosis could enable earlier targeted interventions such as implementation of healthy lifestyle changes in nutritional behavior and exercise or pharmacotherapy, thus reducing disease development. A deeper understanding of the underlying gene- interactions In terms of both public health and for individuals and genetic subgroups is therefor needed.

Buccal Route As A Novel Delivery Route

Ankita S. Dhumal, Sudha Rathod, Jagruti J. Karanjavkar

Buccal administration of drugs provides a convenient route of administration for both systemic and local drug actions. However, the preferred site for retentive oral transmucosal delivery systems and for sustained- and controlled-release delivery devices is the buccal mucosa, mainly because of the differences in permeability characteristics between the two regions and the buccal mucosa’s expanse of smooth and relatively immobile mucosa. The buccal mucosa offers excellent possibilities for the (long-term) delivery of suitable drugs, especially for metabolically unstable drugs, such as peptides. In the development of these buccal drug delivery systems, mucoadhesion of the device is a key element. Mucoadhesive polymers have been utilized in many different dosage forms in efforts to achieve systemic delivery of drugs through the buccal mucosa. Buccoadhesive drug delivery is relatively new drug delivery strategy; in this traditional polymers are replaced by novel bioadhesive polymers such as thiomers & lectins etc. to overcome limitation of traditional polymer.

Buccal Mucoadhesive Drug Delivery Systems

Amit Singh, PranshuTangri, Lakshmayya

Buccal drug delivery is the most innovative delivery system which releases the drug to buccal mucosa by avoiding first-pass metabolism in the liver and pre-systemic elimination in the gastrointestinal tract. Buccal route is an attractive route of administration for systemic drug delivery. Buccal bioadhesive films, releasing topical drugs in the oral cavity at a slow and predetermined rate, The mucosa of the buccal cavity is the most easily accessible transmuocosal site. Buccal transmucosal delivery helps to bypass first- pass metabolism by allowing direct access to the systemic circulation through the internal jugular vein.

Understanding Nanotoxicology and Its Implications for Overcoming Challenges in the Development of Nanoparticles

Sachin B. Somwanshi, Unnati R. Bhoye, Ramdas T. Dolas, Kiran B. Kotade, Kiran B. Dhamak, Vinayak M. Gaware

Nanotoxicology is an emerging new multidisciplinary field of science. This new technology deals with measures, manipulates, and manufactures at the atomic, molecular, and supramolecular levels, aimed at creating materials, devices, and systems with fundamentally new molecular organizations, properties, and functions associated with greater strength, stability, chemical and biological activity. They are used in rapidly increasing nanoproducts, nanodevices, electronics, diagnostics and drug delivery systems. They are present in a variety of consumer products such as foods, drugs, cosmetics, food colour additives, food containers, paints and surface coatings. Because of their extremely small size they are capable of entering the human body by inhalation, ingestion, skin penetration, intravenous injections and medical devices, and have the potential to interact with intracellular macromolecules. Because of their greater stability they are anticipated to remain in the body and in the environment for long periods of time. However, information on their potential adverse health effects is very limited at the present time. It is not known at what concentration or size they can exhibit toxicity. Therefore, there are obvious public safety concerns. This has led to the initiation of a new research discipline commonly known as Nanotoxicology. The current review article reveals the concept of Nanotoxicology from nanomedicine and non-medical nanoparticles.

Swapnali Shahaji Khapare, Mayuri Govind Bhandare, Swati Gokul Talele, Anil Jadhav

Hydrogels are cross-linked polymers with the capacity to swell in a fluid medium. Crosslinking in hydrogels happens by synthetic or physical means relying upon the polymer properties and exploratory conditions. Attributable to a vast assortment in concoction structure and crosslinking strategies, different hydrogels have been set up for different applications in pharmaceutical and biomedical fields. This part starts with brief presentation, preferences, detriments, order, sorts of hydrogel are talked about likewise. They are insoluble because of the nearness of compound (tie-focuses, intersections) and/or physical crosslinks, for example, ensnarement’s and crystallites. These materials can be blended to react to various physiological boosts present in the body, for example, pH, ionic quality and temperature. At last, the part finishes up with known hydrogel applications in the pharmaceutical area.1

Formulation Development and Evaluation of Acyclovir Orally Disintegrating Tablets

Sameer S Mundke, Asish Dev

The Mouth Dissolving Drug Delivery Systems was an advancement that came into existence in the early 1970’s and combats over the use of the conventional tablets, syrups, capsules which are the other oral drug delivery systems. Orally disintegrating dosage forms can address the pharmaceutical needs of the paediatric and geriatric patient group having difficulties in swallowing the conventional solid oral dosage forms. Orally disintegrating dosage forms also have the advantage of self medication, pain avoidance hence better patient compliance. Taste masking of bitter drugs is an important parameter. Orally disintegrating dosage forms may have an added advantage of bypassing first pass metabolism. Acyclovir is an antiviral drug used for the treatment of herpes simplex virus (HSV), mainly HSV-1 and HSV-2 and varicella zoster virus. It is a BCS class III drug. Hence an orally disintegrating tablet formulation of acyclovir was prepared by direct compression techniques after incorporating superdisintegrants croscarmellose sodium , sodium starch glycolate and Crossprovidone . Eight formulations were prepared. Tablet containing sodium starch glycolate and croscarmellose sodium showed excellent in vitro dispersion time and drug release as compared to other formulation. After study of eight formulations F8 showed short dispersion time with maximum drug release in 25 min. It is concluded that fast disintegrating acyclovir tablets could be prepared by direct compression using superdisintegrants.

Vijay P. Jodhani, Ankit B. Chaudhary, Pooja J. Parmar, Dhaval B. Patel

A simple, precise and accurate stability indicating RP-HPLC method has been developed and subsequently validated for the simultaneous estimation of Sildenafil citrate and Estradiol valerate in bulk and pharmaceutical formulation. The separation was carried out using C18 column (150mm x 4.6mm, 5μm), mixture of acetonitrile and water 80:20 % v/v as a mobile phase with a flow rate of 1 ml/min and the effluent was monitored at 290 nm using PDA detector. The retention time of Sildenafil citrate and Estradiol valerate were 2.55 min and 5.56 min respectively. The method is linear over the range of 125 - 750 μg/ml and 5 - 30 μg/ml for Sildenafil citrate and Estradiol valerate respectively. The method was found to be precise, accurate and specific during the study. The percentage assay was found to be 100.68 % and 99.58 % for Sildenafil citrate and Estradiol valerate respectively from the tablet formulation. Sildenafil citrate and Estradiol valerate were subjected to stress condition to check the degradation behaviour of them. The drugs undergo degradation under acidic, basic, oxidative and thermal condition. The proposed method enables rapid quantification and simultaneous analysis of both drugs from commercial formulations without any interference of excipients. So, the method can be used for routine analysis of Sildenafil citrate and Estradiol valerate in combined tablet formulation.

The main objective of present investigation is to formulate fast dissolving tablets of Diclofenac sodium and to evaluate flow, mechanical and release properties of diclofenac sodium tablets formulated by using two different super disintegrating agents namely sodium starch glycolate and microcrystalline cellulose. Two batches of formulations were prepared. F1 to F4 are formulated by using SSG with varying concentrations of 10 mg, 20 mg, 30 mg & 40 mg. similarly next four formulations (F5 to F8) were formulated by taking MCC as superdisintegrant with varying concentrations of 10 mg, 20 mg, 30 mg & 40 mg. All the eight formulations are having good flow properties and are prepared by direct compression technique. Compatibility studies were conducted by using FTIR and all the excipients used in the formulation were compatible with the drug. All the eight formulations shows first order release. The dissolution kinetics was presented in Table 5. The dissolution rate followed first-order kinetics as the graphs drawn between log % drug unreleased vs time were found to be linear. The dissolution rate of diclofenac sodium was found to be effected by the concentration of the superdisintegrant (sodium starch glycolate) used in the preparation of tablets. Based on the dissolution rate, the order of drug release from the four formulations was F4> F3> F2> F1. The formulation prepared with 40 mg of sodium starch glycolate (F4) was offered relatively rapid release of diclofenac sodium when compared with other concentrations employed in this investigation.

A Comparative Study of Timolol Maleate 0.5% v/s Latanoprost 0.005% In the Treatment of Primary Open Angle Glaucoma

Shiwani Chouhan, Jaishree Singh, Ashok Kumar Meena

Glaucoma is an optic neuropathy associated with retinal ganglion cell death that results in visual field loss. Elevated intraocular pressure (IOP) is a primary risk factor for the disease. Glaucoma is the second leading cause of blindness worldwide. Primary open angle glaucoma alone accounts for about 75% of all primary glaucoma. Timolol maleate (non selective β adrenergic antagonist) and Latanoprost (prostaglandin analogue) are commonly used drugs. Our aim of study is to compare the ocular hypotensive effect and safety of topical Timolol maleate (0.5%) and Latanoprost (0.005%) in patients of primary open angle glaucoma. A total of 60 patients with primary open angle glaucoma were included and studied for 6 months. One group of patients were given 0.5% timolol maleate eye drops twelve hourly and other group were given 0.005% latanoprost eye drops once a day. In our study both drugs were significantly effective in lowering the intraocular pressure. The mean fall in IOP in Timolol group was 6.69mmHg (26.10%) and in Latanoprost group was 7.20mmHg (28.5%) from pretreatment values. The difference between the values of mean of reduction in IOP from baseline IOP of the two groups was 0.512 mmHg that was statistically insignificant. The systemic and ocular side effects observed in two groups were comparable and both groups were well tolerated. Timolol maleate and Latanoprost both drugs are effective significantly in lowering the IOP, well tolerated and safe with negligible systemic side effects and comparable ocular side effects.

Synthesis, characterization and screening of antimicrobial activity of metal complexes derived from the mannich base, N-(piperidinomethyl)phthalimide

M. Ramesh

A new Mannich base, N-(Piperidinomethyl)phthalimide (L), formed by the condensation of piperidine, formaldehyde and phthalimide, and its Cu(II) complexes have been synthesized. Their structures have been elucidated on the basis of elemental analysis, molar conductance, IR, UV-visible, mass, 1H NMR and 13C NMR, EPR, magnetic and thermal studies. All the complexes exhibit octahedral geometry. Infrared spectral data show that the organic ligand is bidentate, binding through one of the two carbonyl oxygen atoms of the phthalimide moiety and the piperidine ring nitrogen and also the existence of coordinated water molecules. The X band EPR spectra of Cu(II) complexes in DMSO at room temperature were recorded and their salient features are reported. Thermal data of some of the compounds show that the thermal decompositions take place mostly in two steps to produce metal oxides as final residues. Antimicrobial activities of the newly synthesized compounds were also investigated.

Nada H. Bin Hashim, Syed N. Alvi, Muhammad M. Hammami

A simple and precise reversed-phase high performance liquid chromatography (HPLC) method for the determination of meloxicam in human plasma was developed and validated. Using piroxicam as an internal standard (IS), separation was achieved on Symmetry shield RP-18 column. 0.5 ml plasma samples were prepared by protein precipitation using trifluoroacetic acid and acetonitrile. The mobile phase consisted of 0.025 M dibasic potassium phosphate (pH=6.0, adjusted with phosphoric acid), methanol, and acetonitrile (73:5:22, v:v:v) and was delivered at a flow rate of 1.5 ml/min. Eluents were measured using photodiode array detector set at 355 nm. Under these conditions, no interference in blank plasma or of commonly used drugs was observed. The relationship between the concentration of meloxicam in plasma and peak height ratio of meloxicam to the IS was linear over the range of 0.05-2.0 μg/ml. Intra-day and inter-day coefficient of variations (CV) and biases were ≤ 6.0% and ≤ 8.6%, and ±5.9% and ±5.3%, respectively. Extraction recovery of meloxicam and the IS from plasma was ≥80% and 98%, respectively. The method was applied to assess the stability of meloxicam under various clinical laboratory conditions. In processed samples, meloxicam was stable for at least 24 hours at room temperature (≥ 82%) and 48 hours at -20C (≥ 95%). In unprocessed sample it was stable for at least 24 hours at RT (≥ 82%), 16 weeks at -20ºC (≥ 87%), and after three freeze-thaw cycles (≥ 90%). The method is suitable for clinical and bioavailability investigation involving meloxicam concentration in the therapeutic range.

Pharmacist Role In Drug Efficacy & Safety Implementation On FDC; A Pilot Study

Neethu J, Aparna Vitus, Jinsha Jaffar, Shah Divya Rakesh

Most of the patients in current scenario are treated with more than one anti-hypertensives and most often with fixed dose combinations. Hence the use and efficacy of fixed dose combination are controversial and is the most debated issue in Indian perspective The aim of this randomized pilot study was to evaluate the rationality and side effect profile of fixed dose anti-hypertensive combinations used in our hospital. A total of 25 hypertensive patients prescribed with anti-hypertensive FDCs were randomly selected and their outpatient record were monitored and recorded for a period of 2 weeks. The data was then suitably analyzed. Out of the 13 FDCs, only one FDC (7.69%) have its APIs present in both EML of WHO and NLEM of India. There was no established evidence in terms of therapeutic efficacy and safety for the 3 combinations (23.07%).76.92% of FDCs were cost effective when compared with their individual components. 11 FDCs (84.61%) provide published literature on the reduction of either dose of individual drugs or their adverse effects. Only one FDC was found to be irrational in this study. Giddiness (33.33%) was the most frequently seen side effect among the prescribed FDCs. During this limited study period with only 13 anti-hypertensive FDCs, we were able to find an irrational FDC, which clearly show an urgent need to conduct further studies on evaluating the rationality of FDCs as a whole. As a clinical pharmacist, our immense role in evaluating the rationality of FDCs could enable the DCGI to withdraw irrational FDCs from the market.

Topical drug delivery systems have been utilized for centuries for the treatment of local skin disorders. One side the topical applications of the drug provides the potential advantages of delivering drug straightly to the site of action and delivering drug for extended period of time at the effected site that mainly acts at the related regions. On the other hand, topical delivery system elevates the contact time and mean resident time of drug. The aim of the work is to develop & characterize adapalene emulgel formulation. Adapalene emulgel formulations were prepared by dispersing Carbopol 934 in distilled water with constant stirring at a moderate speed, then the pH was adjusted to 6 - 6.5 using Triethanolamine. Evaluation of the adapalene emulgel was carried out for Physical appearance, Rheological study, pH values, Spreadability, Drug content determination, In vitro release study, Accelerated stability studies. It was noticed that all formulations were liquefied and diluted at the end of the experiments, indicating water diffusion through the membrane. The accelerated stability studies were performed according to ICH guidelines for three months & emulgels were found to be stable in differing temperature. The results demonstrate that the release of the drug is dependent on viscosity of the polymer used.

Abass Tolulope R, Adeleye Isaac A, Adongbede Erute M, Adekunle Adedotun A, Seriki Abiodun.T

Endophytic fungi are potential sources of bioactive secondary metabolites that can be exploited for therapeutic purposes. Our study was aimed to identify bioactive secondary metabolites from crude extracts of endophytic fungi of three popular medicinal plants (Alstonia boonei- Ahun, Enantia chlorantha- Awopa and Kigelia africana- Pandoro) that have ethnobotanical history in Nigeria. The endophytic fungi were isolated from the stem barks of the plants using standard procedures. They were later fermented in broth culture, and the extract from the cell free broth of each of the fungi was subjected to Gas-Chromatography Mass-Spectrophotometry (GCMS). The results showed that, twenty-one different compounds were characterised from Aspergillus niger, Macrophomina sp, Trichoderma sp. and Penicillium species. The bioactive compounds include; Griseofulvin, Cinnamic acids, Penicillin, Coumarin, Cubenol, Erythritol among others. The presence of these compounds may contribute to the therapeutic properties of the plants.

Formulation and Evaluation of Oral In Situ Gel of Metronidazole

Priyanka Chauhan, Asish Dev, Seema Desai, Varsha Andhale

Efficient Helicobacter pylori elimination requires delivery of the antibiotic locally in the stomach. High dose of metronidazole (250 to 750 mg) is difficult to incorporate in floating tablets but can simply be given in liquid dosage form. By keeping the above observation in mind, we made an attempt to build up a new raft forming oral in situ gelling system of metronidazole with improved residence time using sodium alginate as gelling polymer to eliminate H. pylori. Methods: oral in situ gelling formulations were prepared using sodium alginate, xanthan gum, calcium carbonate, and sodium bicarbonate. Prepared formulations were evaluated for density, viscosity, floating lag time, floating duration, swelling index and in vitro drug release. Results. All formulations (F1–F12) showed floating within 180 s and had floating duration of more than 24 h. every formulations showed excellent pourability. It was observed that concentration of sodium alginate and xanthan gum had major influence on floating lag time, cumulative percentage drug release and other evaluation parameters. The batch F11 was optimized since it have good pourability with extended release of 10 hrs. Conclusion: oral in situ gelling system of metronidazole can be formulated by use of sodium alginate as a gelling polymer and xanthan gum as release retardant to control the drug release for more than 10 hrs.

Preformulation Studies of Drugs and Excipients for the Formulation of Salmon Fish oil Nanoemulsion Gel for the Treatment of Psoriasis

Sarfaraz Ahmad, Poonam Rishishwar, Nitesh Kumar

Psoriasis is a prolonged, immune-mediated inflammatory skin disease. It is characterized by sharply demarcated, red, scaly, coin-sized skin lesions most often on the elbows, hands, knees, scalp and feet. Around 10% of individuals with psoriasis develop arthritis, which may affect the hands, feet, wrists, ankles, neck and lower back. In some cases joints become deformed, causing significant disability. The worldwide prevalence of psoriasis is around 2%, but studies in developed countries have reported higher incidence rates of on average about 4.6%. In India the prevalence of psoriasis fluctuates from 0.44 to 2.8%, it is two times more common in males compared to females, and most of the patients are in their third or fourth decade at the time of presentation. Nearly two thirds of people with psoriasis have a mild form of the disease, Therefore in most of the cases first line treatment approach is topical. Betamethsone dipropionate (BD) loaded in omega-3- fatty acid fish oil nanoemulsion for the healthier absorption of BD in deeper layer of the skin to stop further progression of inflammatory cycle. For the preparation of nanoemulsion different types of preformulation studies require to perform because every drug has its specific intrinsic chemical and physical property which has been consider before development of pharmaceutical formulation. This property provides the framework for drug's combination with pharmaceutical ingredients in the fabrication of dosage form.

Analytical Comparison of Different Senna Extracts and Determination of Individual Ratios of Sennosides A & B in Various Senna Extracts

Darshani Sonavaria, Neha Palande, Rajashree Rane, Chetna Chotalia, Ashish Suthar

Constipation is a common problem in all types of ages. Cassia angustifolia (Senna) extracts contain anthranoids that are commonly used for constipation and are well known for their laxative properties. Senna leaves or pods are highly rich with Sennosides content A, B, C & D. These Sennosides are hydroxyanthracene glycosides, which work miraculously as a laxative. In the present study, Senna extract from different vendors with variable strengths of sennosides A&B were procured and the relation between residue on ignition (ROI) with that of metals and sennosides A&B was studied. The optimized concentration of senna extracts containing different sennosides A&B content were analyzed on HPTLC to determine the ratios of sennosides A&B from the total sennosides as well as its relation with residue on ignition (ROI). Residue on ignition (ROI) was analysed gravimetrically while content of Calcium was calculated by Complexometric method. Iron content was carried out spectrophotometrically and Sennosides A&B content was carried out using HPTLC. The process control of extraction can be monitored on the basis of ROI. Specified Sennosides and ROI value together can be used in quality specification. Batch to batch variation with respect to efficacy can be avoided by determining the fixed quality norms for content of Sennosides, ratio of sennosides A&B, ROI value and content of Calcium.

Rapid Determination of Acetaminophen levels in Human plasma by High performance liquid chromatography

Reem Alswayeh, Syed N. Alvi, Muhammad M. Hammami

A simple, precise, and rapid high performance liquid chromatography (HPLC) method for the determination of acetaminophen level in human plasma using caffeine as an internal standard (IS) was developed and validated. 0.5 ml plasma samples containing acetaminophen were mixed with 50 µg of the IS. After adding 30 µl of 50% perchloric acid, the mixture was vortexed for one minute and then centrifuged for 5 minutes at 13200 rpm. The clear supernatant was transferred into an auto-sampler vial and 100 µl was injected into the HPLC system with a run time of 7.0 min. The compounds of interest were efficiently separated on Symmetry C18 (4.6 x 150 mm, 5-µm) column, and were detected with a photodiode array detector set at 245 nm. The mobile phase consisted of water, methanol, and acetonitrile (80:10:10, v:v:v) and was delivered at a flow rate of 0.9 ml/min. No interference in blank plasma or by commonly used drugs was observed; and the detection limit of acetaminophen was 0.05 µg/ml. The relationship between acetaminophen concentration in plasma and peak area ratio of acetaminophen /IS was linear (r2 ≥ 0.9991) in the range of 0.1– 40 µg/ml. Intra- and inter-day coefficient of variations (CV) and biases were ≤11.6% and ≤10.8%, and ≤≤14.0 and ≤12.8, respectively. Extraction recovery of acetaminophen and the IS from the plasma samples was ≥99% and 86%, respectively. Using the method, acetaminophen was found to be stable under conditions generally encountered in the clinical laboratory (≥99% and 91% in processed and unprocessed samples, respectively). Further, the method was successfully used to measure acetaminophen level in plasma samples from a healthy volunteer.

Evaluation of cytotoxic and anticancer activity of prodigiosin produced by Serratia Spp.

Phatake Y.B, Dharmadhikari S.M

Red pigment of Bacillus prodigiosus, now known as Serratia marcescens, were first time investigated and named in 1902. The major component was first isolated in pure form in 1929 and in next 5 years investigators elucidated the main structural features of Prodigiosin and culminated in the assignment of structure. In the present study, potent pigment producing bacteria were used which were previously isolated from soil samples collected from different regions of Baramati, Maharashtra, India. The large scale production of Prodigiosin was achieved by using optimized parameters (time of incubation, temperature of incubation, pH of the medium, speed of Agitation, carbon and nitrogen source used etc.). The effect of red pigment on normal cells was assessed by toxicity studies using trypan blue assay. It shows that pigment having very less or no toxic effect on normal cells at various concentrations (5, 10, 15, 20, 25, 30, 35, 40, 45, 50 µg/ml). The effect of various concentrations (7.8, 15.6, 31.25, 62.5, 125, 250 µg/ml) of pigment on human cancerous cells (Lymphocytes) was also determined by using flow cytometry. Apoptosis was quantified by a reduction in cell forward scatter and increase in cell side scatter in flow cytometric analysis. Study revealed that the produced red pigment may be used for production of effective anticancer drug in future.

Protective Role of Nobiletin on Antioxidants Activity and Xenobiotic Metabolizing Enzymes against Benzo(a)Pyrene Induced Lung Cancer and in Swiss Albino Mice

Kasthuri Kannayiram, Dhivya sathyamoorthy, Selvaraj sundramoorthy, Sakthisekaran Dhanapal

About 1,685,210 new cancer cases are expected to be diagnosed in 2016. Superoxide dismutase protect against oxygen free radicals by catalyzing the removal of superoxide radicals hydrogen peroxide mediated LPO. B(a)P induces the oxidation of mitochondrial NADPH. An increase in the NADP+/NADPH ratio, the low availability of substrate NADPH may be responsible for the decrease in the activity of GR. Reduced glutathione, vitamin C and α-tocopherol comprise the non-enzymatic antioxidant components which protects the cells against the deleterious effects of the free radicals. Phase I & II metabolizing enzymes plays an important role in the detoxification of electrophilic toxicants and their induction protects against carcinogenesis and mutagenesis.

Varsha S. Zade, Gajanan V. Korpe

Formamidines, Thiazoles, dithiazolidines, thiadiazines and other ring system derivatives have a long history of applications in pharmaceutical and agrochemical industries. Our interest in the chemistry of the formamidine nucleus and its derivatives prompted us to explore the synthesis of 1-hepta-O-acetyl- β-D-lactopyranosyl-3-H/Aryl formamidines, N-hepta-O-acetyl- β-D-lactopyranosyl-N’-benzothiozolyl formamidines and N-hepta-O-acetyl-β-D–lactopyranosyl formimidic acid alkyl esters by reductive desulphurization of 1-hepta-O-acetyl- β-D–lactopyranosyl–H / aryl thiocarbamides, 1-hepta-O-acetyl-β-D-lactopyranosyl-3-[2-N-substituted benzothiazolyl] thiocarbamides and 1-hepta-O-acetyl-β-D–lactopyranosyl-O-alkyl thiocarbamates respectively using Raney Nickel. The identities of these newly synthesized derivatives have been established on the basis of chemical transformations and IR, 1H NMR and Mass spectral studies. The title compounds have been assayed for their biological activity against gram-positive as well as gram negative microorganisms. These compounds show most promising activity towards these micro-organisms.

Hybrid Triazoles: Molecular Manipulation As Potential Dual Inhibitor Of Growth And Efflux Inhibition In Methicillin Resistant Staphylococcus Aureus

Prasad P. Dixit, Prashant P. Dixit, Shivajirao N. Thore

Efflux inhibition is proven bacterial machinery responsible for removal of bacterial wastage including antibiotics. Recently, efflux inhibitors (EI) have been tested with encouraging results as an adjuvant therapy for treatment of various bacterial invasions especially methicilline-resistant Staphylococcus aureus (MRSA). Although, EI have emerged as innovative approach of treatment for several multi drug resistant bacterial infections including tuberculosis, toxicity profile limits their wider use. To address this issue, we have attempted synthesizing hybrid molecules those results by combining known EI and triazole. This synthesis was aimed to arrive at structure that possesses pharmacophore from known EI. Synthesized molecules were evaluated as growth inhibitors (GI) and Efflux inhibitor of S. aureus. Pharmacologically active compounds were then tested for their cytotoxicity to further narrow down search. Most active compounds 177, 178, 187 and 196 were then tested for their GEI action against MRSA. We arrived at compound 145 as most potent dual inhibitor.
