SK&F 96365 has been widely used as an inhibitor of transient receptor potential (TRP) calcium channels in various physiological settings. However, growing evidence suggests that SK&F 96365 affects several cellular and molecular processes via uncharacterized off-target mechanisms. In this study, we showed that SK&F 96365 induces apoptosis and autophagy in A7r5 vascular smooth muscle cells. The combined suppression of apoptosis and autophagy provoked necrosis rather than rescued cell death in the cells treated with SK&F 96365. In addition, we found that SK&F 96365 inhibits Akt-mTOR signaling pathways, which is comparable with the efficacy of other known Akt inhibitors. Our findings suggest that SK&F 96365 can be a useful agent for delineating the molecular mechanisms underlying crosstalk among cell death pathways. © 2011.
