Abstract:

A series of IAP antagonists based on thiazole or benzothiazole amide isosteres was designed and synthesized. These compounds were tested for binding to the XIAP-BIR3 and ML-IAP BIR using a fluorescence polarization assay. The most potent of these compounds, 19a and 33b, were found to have K(i)'s of 20-30 nM against ML-IAP and 50-60 nM against XIAP-BIR3.
