Topoisomerase enzymes are highly expressed in cells which undergo rapid multiplication. Inhibition of this enzyme represents a potential therapeutic approach for diseases such as cancer. In order to understand the structure activity correlation of 2, 4, 6 pyridine based topoisomerase inhibitor, we have carried out a combined pharmacophore modelling, 3D-QSAR studies, molecular docking and virtual screening studies. A five point pharmacophore with hydrogen bond acceptor (A), hydrogen bond donor (D) and three aromatic rings (R 5, R 6, R 7) was used to derive a predictive atom based 3d-qsar model. The generated model had showed good correlation coefficient for training set and test set (R2=0.91and Q2=0.827). It was also validated using enrichment factor (EF) and goodness of hit score (GH score) and was used for virtual screening of compounds from ‘zinc drug like database’. Docking study of the hits retrieved from virtual screening revealed the binding affinity of these inhibitors at the active site of topoisomerase enzyme. In silico ADME predictions was also performed. These findings provide a set...

Aim: The present study investigates the effect of Ramipril on blood sugar level and interaction with the oral anti-diabetic drugs in alloxan induced diabetic rats. Method: Rats were divided into 10 groups (n = 6) where Group I –II were normal and Group III –X were diabetic. Ramipril at the dose of 0.9 mg/kg body weight were administered to the normal and diabetic rats. In diabetic groups, the Ramipril was given concomitantly with the each of three Oral anti-diabetic drugs to find-out the effect on blood sugar level .All drugs administered orally once a day for 13 days and at the end of the experimentation Oral Glucose Tolerance Test (OGTT) was conducted. Results: It was observed that in normal rats the Ramipril slightly reduced the blood sugar level which was insignificant (P>0.05) except at ‘30’ min time point. In contrast in, it exhibited the anti-hyperglycemic activity significantly (P≤0.01) at all-time points in alloxan induced diabetic rats. Conclusion: The present study has concluded that The Ramipril has significant anti-hyperglycemic activities...

Aim: Cellulite treatment incorporates iso-slim complex to reload the skin with minerals and trace elements to achieve absolute effectiveness in treating cellulite condition. The revitalizing effect of anticellulite helps to refine and reshape the silhouette and give the body a more toned, defined and firmer appearance. Aim of present work was to develop and investigate a novel delivery system for the fatty skin in the form of liposome delivery system. Method: Phosphatidylcholine, Cholesterol and iso-slim complex were dissolved in chloroform/methanol (2:1, v/v) mixture and subsequently transferred into a pear-shaped flask connected to a Rotavapor (Buchi- type). Rotary evaporation method was used for the formulation of liposomes. Result: Liposome prepared was evaluated for particle size measurement, percent drug entrapment, formulation of dosage forms, Stability Study and in vivo study. Optimized batch had particle size 18.62 um, percent drug entrapment 96.70%. Hence, optimized was batch further evaluated for in vivo study and stability study. Conclusion: The present study has been a satisfactory attempt to formulate and evaluate liposome of iso-slim complex...

Ayurvedic formulations are used to treat a wide variety of diseases including Diabetes Mellitus Standardization of Herbal Formulation is Essential in order to assess the Quality of drugs. The Present Study Reports for Standardization of Eight Herbal Anti-diabetic drugs- Momordica charantia (seeds), Syzigium cumini (seeds), Trigonella foenum (seeds), Azadirachta indica (leaves), Emblica officinalis (fruits),Curcuma longa (rhizomes), Gymnema sylvestre (leaves),Pterocarpus marsupium (heart-wood) individually and in the form of Polyherbal marketed samples of Baidyanath Madhumehari Churna, Shivayu Madhuhari Churna and were compared to the in-house preparation for Physicochemical properties as per WHO Guidelines. The Limits obtained from the different Physicochemical Parameters of the individual Eight Herbal drugs and the Marketed Formulations could be used as Reference Standard for Standardization of the Anti-diabetic drugs in a Quality Control...
