DeBio-1143, also known as AT-406, ARRY-334543and SM-406, is an orally bioavailable inhibitor of IAP (Inhibitor of Apoptosis Protein) 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). This may restore and promote the induction of apoptosis through apoptotic signaling pathways. AT-406 may work synergistically with cytotoxic drugs to overcome tumor cell resistance to apoptosis.
