Investigations on Binding Pattern of Kinase Inhibitors with PPARγ : Molecular Docking, Molecular Dynamic Simulations, and Free Energy Calculation Studies

Peroxisome proliferator-activated receptor gamma (PPAR gamma) is a potential target for the treatment of several disorders. In view of several FDA approved kinase inhibitors, in the current study, we have investigated the interaction of selected kinase inhibitors with PPAR gamma using computationalmodeling, docking, and molecular dynamics simulations (MDS). The docked conformations and MDS studies suggest that the selected KIs interact with PPAR gamma in the ligand binding domain (LBD) with high positive predictive values. Hence, we have for the first time shown the plausible binding of KIs in the PPAR gamma ligand binding site. The results obtained from these in silico investigations warrant further evaluation of kinase inhibitors as PPAR gamma ligands in vitro and in vivo.
