DESIGNING OF 2, 5-DISUBSTITUTED-1,3,4-THIADIAZOLE DERIVATIVES FOR THEIR ANTICONVULSANT POTENTIAL

QSAR is the study of quantitative relationships between biological activity and the physicochemical properties of a common parent structure molecule. CS chemoffice software utilized for QSAR of series. The reported IC50 values were converted to negative log IC50 values, which were correlated with various descriptors. Upon stepwise, multiple, and sequential regression analysis of descriptor, the statistically significant QSAR equations were obtained. The correlation between the physicochemical parameters and the biological activity were found using the least squares method. The equations having good correlation coefficient (r2), F-test value, SD values and minimum variance were validated by the cross validation method and IC50 and pIC50 values were calculated using Valstat. 5-Benzenesulphonamido-1,3,4-thiadiazol-2-sulphonamide, was designed as parent structure

Evaluation of Polyherbal Anticancer Tablets: A Review

Cancer is a malignant abnormal growth of cells, one of the most dreaded and complex diseases. It concerns with several tempo spatial changes in cell composition, which finally lead to neoplasia. Various types of cancers have been reported. Chemotherapy, radiation, and/or surgery may cure them. Herbal remedies are supposed to be harmless as they cause fewer complications and are less likely to habitual. Antioxidant compositions of therapeutic plants show the anticancer activity and therefore, use of different proportions of the active components to formulate various standardized preparation with single or multiple components for their synergistic effects play a crucial role in curing cancer. Evaluation parameters to assess the in vitro anticancer activity includes Caspase-3, Caspase-9, alamar blue, LDH assay, XTT assay, sulforhodamine-B assay, MTT assay, DNA fragmentation assay, neutral red uptake cytotoxic assay, tryphan blue assay. Evaluation of dried extract or granules includes bulk density, tapped density, Carr’s index, Hausner’s ratio, angle of repose while the tablets evaluated by drug-excipient compatibility study by FT-IR, stability studies, hardness, thickness, weight variation, friability, disintegration time and dissolution test

Phytochemical Investigation and Pharmacological Evaluation of Solanum xanthocarpum Endowed with their potential Activity

The study was done to assess the in-vitro antibacterial potential of various extracts was studied and compared with ciprofloxacin as the standard and shows significant action against E. coli, B. substilis S. aureus, S. pyrogenes, P. aeruginosa, and S. typhi. Anti-fungal potential of the aqueous extract also studied using miconazole as standard and shows significant action against A. niger and C. albicans. Anthelmintic potential of the aqueous and ethanolic extracts was also studied on earthworms, Eudrillus eugeniae using albendazole as standard and shows moderate activity. In the present study in-vitro free radical scavenging activity of whole plant material performed. Various crude extracts of S. xanthocarpum was prepared by successive maceration process using various solvents such as; chloroform, petroleum ether (60-80o), acetone, ethanol and distilled water. Each one extract have been chosen to study the free radical inhibitory activity by DPPH radical scavenging method. The preliminary phytochemical screening of extracts showed that sterols, alkaloids, glycosides, tannins, saponins, phenolic compounds, carbohydrates and proteins were present in the plant. Petroleum ether, chloroform, acetone, ethanol and distilled water extracts showed 52.69, 46.15, 21.08, 52.72 and 44.35 % respectively compared to standard ascorbic acid. Acetone extract showed poor inhibition of DPPH radical compared to standard and other extracts also
