SM-164 | B1816

SM-164 is a potent cell-permeable and bivalent Smac mimetic which binds to a XIAP protein with a Ki value of 0.56 nM, and binds to cIAP-1 and cIAP-2 proteins with Ki values of 0.31 and 1.1 nM, respectively. It displays antitumor properties through inducing degradation of cellular inhibitor of apoptosis protein (cIAP)-1/2, antagonizing X-linked inhibitor of apoptosis protein (XIAP) and inducing TNFα–dependent apoptosis in tumor cells.
