Normal progression through the cell cycle requires the sequential action of cyclin-dependent kinases (CDK1, CDK2, CDK4 and CDK6). Deregulation of CDK activity is a feature of almost all cancers and has led to the development of CDK inhibitors as anticancer agents. As such, CDK7 is an target for the anticancer drug development. Computer modeling of CDK7 was used to design potential potent CDK7 inhibitor, which is BS-181.
In vitro: Testing of other CDKs as well as another 69 kinases showed that BS-181 only inhibited CDK2 at concentrations lower than 1 μM, with 35-fold less potently (IC50 880 nM) than CDK7. BS-181 inhibited the phosphorylation of CDK7 substrates in MCF-7 cells, led to cell cycle arrest and apoptosis to inhibit the growth of cancer cell lines, and showed antitumor effects in vivo .
In vivo: BS-181 was stable in vivo after i.p. administration of 10 mg kg-1. The same dose of drug inhibited the growth of MCF-7 human xenografts in nude mice. BS-181 is the first example of a potent and selective CDK7 inhibitor with potential as an anticancer agent .
Clinical trial: Currently no clinical data are available.
