Abstract

A series of hybrid compounds of bestatin (1) and actinonin (3), which promote degradation of cellular inhibitor of Apoptosis protein 1 (cIAP1), were designed and synthesized. Structure-activity relationship studies indicated that absolute configuration, hydrophobicity at the alpha-position of the internal amide carbonyl group, and the presence of a small substituent at the alpha-position of the ester group are important factors for the expression of potent cIAP1 degradation-promoting activity. HAB-5A (30b) showed the most potent activity (IC(50)=0.53 microM) among the compounds prepared.
