AT-406 is an orally bioavailable inhibitor of IAP family of proteins with potential apoptotic inducing and antineoplastic activity. AT-406 selectively inhibits the biological activity of IAP proteins, including X chromosome-linked IAP (XIAP), the cellular IAPs 1 (c-IAP1) and 2 (c-IAP2) and melanoma inhibitor of apoptosis protein (ML-IAP).
GDC-0152 is a second mitochondrial activator of caspases (Smac) mimetic inhibitor of IAPs (Inhibitor of Apoptosis Proteins) with potential antineoplastic activity.
AZD5582 is an antagonist of the inhibitor of apoptosis proteins (IAPs), which binds to the BIR3 domains cIAP1, cIAP2, and XIAP with IC50s of 15, 21, and 15 nM, respectively.
