Antagonist Comments
AZD5582 is a peptide mimetic. It consists of a dimeric structure, with sequences based on the AVPI motif of DIABLO (aka Smac; Q9NR28). DIABLO is a peptide of mitochondrial origin and is an endogenous pro-apoptotic antagonist of IAP protein function.
Immunopharmacology Comments
Cellular inhibitors of apoptosis proteins BIRC2 and BIRC3 are required for efficient caspase-1 activation by the inflammasome [6], and represent novel drug targets in inflammatory processes [7].
