Identification of phyto-compounds from Mangifera indica as inhibitors of 17β-hydroxysteroid dehydrogenase: a computational approach against prostate cancer.

Prostate cancer (PrCa) is a serious health concern for the affected people and, there is an increasing demand for a viable therapy that can address the limitations of current treatments with minimal or no adverse effects. This study aims to evaluate phytocompounds extracts of Mangifera indica as a potential therapy development for prostate cancer. Herein, molecular docking, QSAR, molecular mechanics/generalized born surface area (MM/GBSA) estimation, ADME screening, and molecular dynamics (MD) simulation were performed using the Schrodinger suite to identify 17β-hydroxysteroid dehydrogenase antagonist from Mangifera indica. The results showed that fisetin (-11.669), riboflavin (-10.918), quercetin (-10.843), gallic acid 6-phenylhexyl ester (-10.817), cianidanol (-10.608), (-)-epicatechin (-10.603), ellagic acid (-10.522), Butin (-10.124) in kcal/mol were predicted to possess greater inhibitory activities against the protein target based on their high binding energies and remarkable stability compared to the standard drug, docetaxel (-7.374 kcal/mol). Fisetin (-718.37), and riboflavin (-722.37) also have better induce fit score than docetaxel (-714.02) in kcal/mol with better pharmacokinetics profile compared to the standard drug.MD simulation over 100 ns predicts that Fisetin forms stable interactions with vital residues at the catalytic site of the protein. The observations from this study predict fisetin as a putative antagonist of 17β-hydroxysteroid dehydrogenase and should be experimentally verified as a lead compound for prostate cancer therapy.
