CUDC-427, also known as, GDC-0917, is an orally available, monovalent mimetic of second mitochondrial-derived activator of caspases (Smac/DIABLO) and inhibitor of IAPs (Inhibitor of Apoptosis Proteins) with potential antineoplastic activity. Smac mimetic CUDC-427 binds to the Smac binding groove on IAPs, including the direct caspase inhibitor X chromosome-linked IAP (XIAP) and the cellular IAPs 1 and 2. This inhibits the activities of these IAPs and promotes the induction of apoptosis through apoptotic signaling pathways.

Additional Information

 CUDC-427 is currently developed by Curis, Inc , who licensed from Genentech. CUDC-417 is an orally bioavailable small molecule that triggers tumor cell apoptosis by selectively antagonizing IAP proteins. CUDC-427 was designed to mimic the endogenous IAP antagonist, second mitochondria-derived activator of caspases/direct IAP-binding protein (Smac/DIABLO) that is released into the cytoplasm in response to pro-apoptotic stimuli. CUDC-427 has demonstrated single-agent and combination therapy anti-tumor activity in mouse xenograft tumor models when administered orally, and IND-enabling safety studies have shown it to be well tolerated when dosed daily by oral administration, potentially enabling sustained target inhibition.  CUDC-427 is currently developed by , who licensed from Genentech.
