The Bcl-2 family proteins include pro- and antiapoptotic factors acting as critical arbiters of apoptotic cell death decisions in most circumstances. Evasion of apoptosis is one of the hallmarks of cancer, relevant to tumorigenesis as well as resistance to cytotoxic drugs, and deregulation of Bcl-2 proteins was observed in many cancers. Since Bax-mediated induction of apoptosis is a crucial mechanism in cancerous cells, we aimed at conducting in silico analysis on Bax in order to predict the possible interactions for anticancer agents. The present report depicts the binding mode of aloe-emodin and its structurally modified derivatives onto Bax. The structural information about the binding site of Bax for docked compounds obtained from this study could aid in screening and designing new anticancer agents or selective inhibitors for chemotherapy against Bax.
