SNX-2112 is an Hsp90 inhibitor which is currently undergoing multiple phase 1 clinical trials; however, its mechanism of action needs to be further elaborated. Here we investigated the effects of SNX-2112 in A-375 cells. SNX-2112 induced the degradation of multiple Hsp90 client proteins, activated both the mitochondrial-mediated and death receptor-mediated apoptotic pathways, downregulated Bcl-2 and Bcl-xL, upregulated Bid, cleaved caspase-9, caspase-7, caspase-3 and PARP, and activated caspase-8. The general caspase inhibitor, z-VAD-fmk, did not completely abolish SNX-2112-induced cell death. SNX-2112 induced autophagy in a time- and dose-dependent manner via Akt/mTOR/p70S6K inhibition. SNX-2112 induces significant apoptosis and autophagy in human melanoma A-375 cells, and may be an effective targeted therapy agent.
