Structure-Based Design, Synthesis, and Evaluation of Conformationally Constrained Mimetics of the Second Mitochondria-Derived Activator of Caspase That Target the X-Linked Inhibitor of Apoptosis Protein/Caspase-9 Interaction Site
摘要:
A successful structure-based design of conformationally constrained second mitochondria-derived activator of caspase (Smac) mimetics that target the XIAP/caspase-9 interaction site is described. The most potent Smac mimetic 12d has a K-i of 350 nM for binding to the XIAP BIR3 domain protein. 12d is found to be effective in enhancing apoptosis induced by cisplatin in PC-3 human prostate cancer cells.
