Design, Synthesis and Evaluation of 5-pyridin-4-yl-2-thioxo-[1,3,4]oxadiazol-3-yl Derivatives as Anti-angiogenic Agents Targeting VEGFR-2.

Background: Angiogenesis is physiological process in embryogenesis, organ development, endometrial vasculature in menstrual cycle and wound healing. Angiogenesis has also been associated with several pathological conditions such as cancer, arthritis, atherosclerosis, etc. Out of the many growth factor responsible for angiogenesis, vascular endothelial growth factor (VEGF) is one of the most important and positive regulator of angiogenesis with its distinct specificity for vascular endothelial cells.

Warfarin therapy--why one dose does not fit all!

We report an Indian adult female patient with Deep Vein Thrombosis (DVT), in whom it was difficult to achieve and maintain target INR on warfarin (oral anticoagulant) by conventional doses. Pharmacogenomics study for warfarin revealed that she had Homozygous mutant for CYP2C9 *3(CYP2C9 *3/*3) and Heterozygous mutant for VKORC 1(1639G >A) {genetic polymorphism double defect}. This conferred a greater sensitivity to her warfarin therapy in an otherwise conventional dose regime used in most patients, making her management challenging.

Polysaccharide enriched immunomodulatory fractions from Tinospora cordifolia (Willd) miers ax hook. f. & Thoms.

Tinospora cordifolia is used in Ayurveda as "Rasayanas" to improve the immune system and the body resistance against infections. Polysaccharides are the main constituents which are considered to be responsible for immune enhancement. In this study, immunomodulatory activity of three polysaccharide enriched fractions was evaluated using the polymorphonuclear leukocyte function test.
