Abstract

Abstract A series of 5′-phenyl-3′ H-spiro [indoline-3, 2′-[1, 3, 4] thiadiazol]-2-one analogs were synthesized and their Bcl-2 protein inhibitory activities were studied. The lead compound was originally identified using a fluorescence polarization-based competitive binding assay. Among the 10 compounds investigated, 1k showed good binding affinities to Bcl-xL and Mcl-1, with inhibition constants of 8.9 μmol/L and 3.4 μmol/L, respectively. ...
