The anti-ulcer activity of aqueous extract of Annona squamosa leaves was investigated on a indomethacin induced ulcer models in wistar rats. In model the common parameter determined was ulcer-index. aqueous extract of dosage 175, 350 mg/kg p.o produced significant inhibition of gastric lesions induced by indomethacin induced ulcers. The extract 175mg/kg & 350mg/kg showed significant (p<0.01) reduction in gastric volume, free acidity and ulcer index as compared to control. This present study indicate that Annona squamosa leaves extract have potential anti ulcer activity. This results may further suggests that aqueous extract was found to posses antiulcerogenic as well as ulcer healing property,which might be anti secretory...

The present study was designed to investigate the antidiabetic potential of different extracts of Berberis aristata bark, in alloxan induced diabetic male wister albino rats (150-250g), Diabetes was confirmed after 5 days of single intraperitoneally injection of alloxan (140 mg/kg of body wt.) in 12 hours previously fasted rats. Petroleum ether extract of Berberis aristata (PEBA) (100 & 400 mg/kg, body wt.) & Ethanolic extract of Berberis aristata (EEBA) (100 & 400 mg/kg, body wt.) and the standard drug glibenclamide (10 mg/kg, body wt.) were given orally in 0.5% Tween 80 after 5 days of alloxan treatment daily for 20 days, except the normal and diabetic control group (n=6). Blood was collected from the retro orbital sinus of the rats for glucose, total cholesterol and triglyceride level determination on 1st, 5th, 10th and 20th days. PEBA (100 & 400 mg/kg, body wt.) showed significant reduction in blood glucose level (266.3 ± 0.9700 to 118.1 ± 0.9375mg/dl & 271.3 ± 0.6983 to 111.6 ± 0.8072 mg/dl, respectively), total cholesterol (92.40±0.7711mg/dl...

Punica granatum L. belongs to the family Punicaceae, which is originating from the Middle East, extending throughout the Mediterranean, eastward to China and India. Punica granatum has been used extensively as a traditional medicine in many countries for the treatment of dysentery, diarrhea, helminthiasis, acidosis, hemorrhage and respiratory pathologies. In addition, P. granatum is reported to have antioxidant, anti-atherosclerotic and antiviral properties. The dried pomegranate peels (20gms) were extracted using water (100ml) & ethanol (100 ml). The Ethanolic Extract of Punica granatum (EPG) was active against the tested bacteria. EPG demonstrated promising antibacterial activity against tested gram positive and gram negative bacteria. The E. coli and S. aureus shows more susceptibility to...

A new series of 2, 5-disubstituted-1, 3, 4-oxadiazole derivatives were synthesized using appropriate methods & structures of the synthesized compounds were confirmed by IR,NMR & Mass spectral data.. These ligands were prefiltered for their drug likeness properties by Lipinski’s rule of 5 and it was found that all the ligands satisfied the rule of 5 for oral bioavailability.The prefiltered ligands were subjected for docking studies using integrated web server called docking server to investigate the interactions between the target compounds and the amino acid residues of the Glycogen synthase kinase-3β. The docking studies were done using auto dock between computationally designed 2,5-disubstituted 1, 3, 4-oxadiazole derivatives and Glycogen synthase kinase-3beta (GSK-3β) protein. The Calculated free energy of binding and estimated inhibition constants (Ki) were remarkable when compared with the standard GSK-3 inhibitors. It is calculated by the Lamarckian Genetic Algorithm (LGA). These values & the proposed interactions suggested that the 2, 5-disubstituted-1, 3, 4-oxadiazole derivatives are excellent inhibitors of...

Some new series of 3-(4-substituted-phenyl)- 2-thioxo-2,3-dihydroquinazolin-4(1H)-one, 3-(4-substituted-phenyl)-2-(methylthio)quinazolin-4(3H)-one and 3-(4-substituted-phenyl)-2-hydrazinylquinazolin-4(3H)-one were synthesized by cyclization of 4-substituted-phenylcarbamodithioate with methyl anthranilate followed by reaction with dimethylsulphate and then prepared compound was refluxed with hydrazinehydrate respectively. The starting material 4-substituted-phenylcarbamodithioate was synthesized from 4-substituted-aniline. The title compounds were investigated for antibacterial and antifungal activity by disc diffusion technique. Compound IIa, IIb and IIIa showed moderate activity against B. subtilis, E. coli and A. niger as compared to standard drug. Compound IIIb and Iva exhibited good activity against A. niger. Compound IIIc and IVc was found to be most active compound against E. coli and moderately active against B. subtilis and A. niger, of the prepared...
