The inhibitor of apoptosis (IAP) proteins are critical regulators of cancer cell survival, which makes them attractive targets for therapeutic intervention in cancers. Herein, we describe the structure-based design of IAP antagonists with high affinities and selectivity (>2000-fold) for c-IAP1 over XIAP and their functional characterization as activators of apoptosis in tumor cells ...
