Synthesis and biological activity of new resveratrol derivative and molecular docking: dynamics studies on NFkB.

Resveratrol (RVS) is a naturally occurring antioxidant, able to display an array of biological activities. In the present investigation, a new derivative of RVS, RVS(a), was synthesized, and its biological activity was determined on U937 cells. It was observed that RVS(a) showed pronounced activity on U937 cells than RVS.

Comprehensive structural and functional characterization of Mycobacterium tuberculosis UDP-NAG enolpyruvyl transferase (Mtb-MurA) and prediction of its accurate binding affinities with inhibitors.

Tuberculosis (TB) remains the most frequent and important infectious disease causing morbidity and death in the world. One third of the world's population is infected with Mycobacterium tuberculosis (Mtb), the etiologic agent of TB. The bacterial enzyme MurA catalyzes the transfer of enolpyruvate from phosphoenolpyruvate (PEP) to uridine diphospho-N-acetylglucosamine (UNAG), which is the first committed step of bacterial cell wall biosynthesis.
