Synthesis and biological evaluation of 5'-phenyl-3'H-spiro-[indoline-3,2'-[1,3,4]oxadiazol]-2-one analogs

引用

Chinese Chemical Letters 2013年第10期24卷 929-933页

作者： Hua-Quan Liu de-cai wang Fei Wu Wei Tang Ping-Kai Ouyang School of Pharmaceutical Science Nanjing University of Technology College of Life Science and Pharmaceutical Engineering Nanjing University of Technology

A series of 5＇-phenyl-3＇H-spiro[indoline-3,2＇-[l,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, I k showed good binding affinities to Bcl-xL and Mcl-l, with inhibition constants of 8.9 μmol/L and 3.4 μmol/L, respectively. While compound lc achieved tight binding affinities to Bcl-xL （Ki= 0.16 μmol/L）, has the potential to be a new lead compound.
