BS-181 HCl Chemical Properties,Usage,Production

Biological Activity

normal progression through the cell cycle requires the sequential action of cyclin-dependent kinases cdk1, cdk2, cdk4, and cdk6. direct or indirect deregulation of cdk activity is a feature of almost all cancers and has led to the development of cdk inhibitors as anticancer agents.bs-181 is a highly selective cdk7 inhibitor with ic50 of 21 nm. ; >40-fold selective for cdk7 than cdk1, 2, 4, 5, 6, or 9.

in vitro

bs-181, inhibited cak activity with an ic50 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 μmol/l, with cdk2 being inhibited 35-fold less potently (ic50 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 [1].

in vivo

bs-181 was stable in vivo with a plasma elimination half-life in mice of 405 minutes after i.p. administration of 10 mg/kg. the same dose of drug inhibited the growth of mcf-7 human xenografts in nude mice. bs-181 therefore provides the first example of a potent and selective cdk7 inhibitor with potential as an anticancer agent [1].
