Abstract

Nicotinamide Phospho ribosyltransferase (NMPRTase) is an enzyme catalyses the biosynthesis of NAD+. It is generally expressed more in cancerous cell lines. The inhibitors targeted to NMPRTase reduce the cellular NAD+ concentration which results in apoptosis and cell death, hence can be used to treat cancer. These inhibitors could also target the NAD+ dependent enzymes like sirtuins indirectly, which were implicated in many diseases like diabetes, neurodegeneration and inflammation. Thus designing inhibitors to NMPRTase would be a good strategy to treat various disorders. In the present work, crystal structure of NMPRTase (2GVJ) with 2.1 A o resolution, was employed for the energy based pharmacophore model generation for the crystal ligand (FK866) and virtual screening was carried out using Glide docking (Schrodinger). Commercial databases were used for virtual screening.Top30 potential hits were shortlisted by comparing pharmaophore fitness, docking score and hydrogen bonds with crystal ligand. These top hits are the potential lead compounds for treating cancer and other disorders.
