BS-181 hydrochloride Usage And Synthesis

Uses

BS-181 is a potent and selective CDK7 inhibitor (IC50=21 nM) than Seliciclib (HY-30237). BS-181 is also against CDK2, CDK5 and CDK9 with IC50 values of 880, 3000 and 4200 nM, respectively (fails to block CDK1, 4 and 6). BS-181 inhibits a panel of cancer cells growth (IC50=11.5 μM-37.3 μM) and induces cell apoptosis. BS-181 has the potential for the research of cancer therapy[1][2].

Definition

ChEBI: N5-(6-aminohexyl)-N7-(phenylmethyl)-3-propan-2-ylpyrazolo[1,5-a]pyrimidine-5,7-diamine is a pyrazolopyrimidine.

in vivo
