Diabetes is a non communicable chronic metabolic disease characterized by high blood glucose level in the body. Targeting alpha amylase to control diabetes has long been studied. This study focused on developing pharmacophore model for set of inhibitor that possess anti amylase activity based on previous studies. Developing a pharmacophore model for these compound yields a hypothesis of ADDRR. Furthermore 3D QSAR model is carried out with good correlation activity for training set as .98 and test set as .92. Database screening for the developed model list out top compounds. High throughput virtual screening is performed for this top compound set. Two ligands quercetin 3-glucosyl rhamnosyl galactoside and rhodionin is found to have good binding affinity over alpha...

The experiment was performed at the Department of Pharmacology in collaboration with the animal house Microbiology Department, Bangladesh Agricultural University, Mymensingh during the period from Jan 2005 to May 2005. To complete the research work following steps were followed.The aim of this study was to assess the possible comparative efficacy of Turmeric (Halud), Garlic (Rashun) and Aloe (Ghrita kumari) with Antibiotic Nebanol (Neomycin Sulphate and Bacitracin Zinc) on artificially induced wound in 2.5 cm length and 0.5 cm depth were made on the two thigh muscles an experimental model. Twenty five guinea pigs of both sexes age ranged between 6 to 8 months were divided into five groups (each group containing five animals). The first, second and third groups received herbal medicine e.g.; Turmeric paste, Garlic paste, Aloe gel and fourth group received Antibiotic Nebanol powder (Neomycin Sulphate and Bacitracin Zinc) respectively. The fifth/control groups were observed without medicine. Turmeric, Garlic, Aloe & Nebanol treatment reduced the wound within 12, 15, 17 & 14 days respectively. On the other...

Tithonia diversifolia was collected from 27 localities of Côte d’Ivoire. The oils of the leaves and stems obtained by hydrodistillation using Clevenger-type apparatus have been studied by GC and GC-MS. The identified components accounted for 91.4% – 96.9% of leaves and 93% – 95.6% of stems. The content of the main components varied from sample to sample. α-pinene (0.9 – 47.4%), limonene (0.5 – 65.5%), (Z)-β-ocimene (0.0 – 35.9%) and 3-methyl-2 (2-methylbuthenyl) furan (0 – 94%) were noted as major components of the oil from the leaves. Whereas, the stem oil was rich in α-pinene (5.8 – 89.8%), sabinene (0. – 5.2%), β-pinene (0.3 – 10.5%), limonene (1.3 – 36.5%), (Z)-β-ocimene (0 – 39.3%), thymol (0 – 4%) and spathulenol (0.1 – 11.8%). Due to the chemical polymorphisme, the results of oil obtained from leaves and stems were submitted to hierarchical cluster, principal components analysis and discriminant factoriel analysis which allowed the distinction of two groups within the oil samples of each organ. According to the essential oil from...

A simple, rapid, specific, precise and accurate UV Spectrophotometric method for simultaneous estimation of Serratiopeptidase and Diclofenac sodium in bulk and tablet formulation has been developed. UV Spectrophotometric method was developed for the simultaneous estimation of Serratiopeptidase and Diclofenac sodium in tablet formulation. In present work, simple, sensitive, accurate and economical spectroscopic method has been developed for the estimation of Serratiopeptidase and Diclofenac sodium in bulk and its pharmaceutical dosage forms. An absorption maximum was found to be at 275nm for Diclofenac sodium and 264nm for serratipeptidase with the solvent Ethanol 99.99%. Diclofenac sodium follows beer’s law in the range of 5-50μg/ml with correlation coefficient of 0.998 and Serratiopeptidase in the range of 5-50μg/ml with correlation coefficient of 0.995. Results of the analysis were validated for accuracy, precision, LOD, LOQ and were found to be satisfactory. The proposed method is simple, rapid and suitable for the routine quality control...

Warfarin and coumarin containing drugs act on Vitamin K epoxide reductase to show its anti-coagulant activity. In this study, three different series of 5- hydroxy coumarin containing phenyl, furan and pyran substituents at third position were designed. Molecular docking studies were performed to determine binding modes and affinities of ligand molecule towards Vitamin K epoxide reductase. In docking studies pair wise linear potential (PLP score) was used as a scoring function and systematic search method to find out bio active conformer. Ligand 2B, 2C, 2D, 2E, 3C, 3D has shown more negative binding energies, which reflects its affinity towards a vitamin K epoxide reductase. Ligand 1A, 1E, 3D has shown maximum hydrogen bond interactions as compared to warfarin. Tyr178, Thr72, Met111, Glu115amino acid residues were involved in the ligand-protein interactions. Hydroxy, methoxy, ethoxy and methyl substitutions has played major roles in the ligand-protein interaction. Therefore, 3-substituted -5-hydroxy coumarins could be served as good drug candidates for anticoagulant activity and additional experimental studies are warranted to locate their importance as...
