Abstract
Prostate cancer is one of the frequently diagnosed cancers in men. In prostate cancer, initiation to the appearance of symptoms is a very long period. Due to its high latency period it paved the way for the chemoprevention. Chemopreventive drugs quickly and effectively eliminate pre-malignant cells by inducing apoptosis. In this context, the present study utilized an integrated approach of in silico and in vivo analysis to find an effective chemopreventive drug, which induces apoptosis. Three phytocompounds from Gymnema sylvestre were screened against anti-apoptoic proteins (Bcl-2 and Bcl-xl) through in silico analysis and the best compound was identified as dihydroxy gymnemic triacetate. Its chemopreventive activity was analyzed in the N-methyl-N-nitrosourea and Testosterone-induced Sprague-Dawley rats. The result indicates that anti-apoptotic proteins (Bcl-2, Bcl-xl) level were significantly increased in cancer-induced animals compared to control whereas treatment with dihydroxy gymnemic triacetate supplementation significantly maintained the protein expression in par with control rats. This study suggests that dihydroxy gymnemic triacetate may act as a potential chemopreventive agent in targeting the prostate cancer. Thus, these findings may open novel prospective in cancer chemoprevention.
