Abstract. A series of tricyclic, conformationally constrained Smac mimetics have been designed, synthesized, and evaluated. The most potent compound 6 (WS-5) binds to XIAP, cIAP-1, and cIAP-2 with Ki of 18, 1.1, and 4.2 nM, respectively. Compound 6 antagonizes XIAP in a functional assay, induces cIAP-1 degradation, inhibits cell growth with an IC50 of 68 nM in the MDA-MB-231 cancer cell line, and effectively induces cancer cells to undergo apoptosis.
