Abstract: Caveolin-1 (Cav-1) is 22 kDa caveolae protein, acts as a scaffold within caveolar membranes, interacts with Gα-protein and thereby regulates their activity. Earlier studies reported elevated caveolin-1 levels in the serum of prostate cancer patients. Secreted Cav-1 promotes angiogenesis, cell proliferation and anti-apoptotic activities in prostate cancer patients. This study was designed to explore Cav-1 as a target for prostate cancer therapy using computational approach. Molecular docking, structural base molecular modelling and molecular dynamics simulations were performed to investigate Cav-1 inhibitors. A predictive model was used for virtual screening against ZINC database of biogenic compounds. Stability of the active site residues of Cav-1 was estimated by IFD and 100 ns long molecular dynamic simulations. The reported compounds showed significant binding and thus can be considered potent therapeutic inhibitors of Cav-1. Thus, further investigative studies on the biochemical interactions of Cav-1 would provide a valuable insight into its probable therapeutic applications.
