Mitochondrial release of cytochrome c triggers apoptosis via the assembly of a multimeric complex including caspase-9, Apaf-1, and other components, sometimes called the apoptosome.¹ Library screens have identified small molecules that activate the apoptosome by binding to one or more of its components. CAY10443 is one such molecule. In a cell free, multi-component assay, it activated caspase-3 with an EC₅₀ of 5 µM.² These apoptotic activators represent therapeutic lead compounds for the development of antitumor drugs.
