Description: BS-181 is a highly selective CDK inhibitor for CDK7 with an IC(50) of 21 nmol/L. Testing of other CDKs as well as another 69 kinases showed that BS-181 only inhibited CDK2 at concentrations lower than 1 micromol/L, with CDK2 being inhibited 35-fold less potently (IC(50) 880 nmol/L) than CDK7. In MCF-7 cells, BS-181 inhibited the phosphorylation of CDK7 substrates, promoted cell cycle arrest and apoptosis to inhibit the growth of cancer cell lines, and showed antitumor effects in vivo.
