| Bioactivity | 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]. | ||||||||||||
| Invitro | BS-181 (0-40 μM; 72 hours) inhibits cancer cells growth, it is against Breast cancer cell lines growth with IC50 values ranging from 15.1 μM to 20 μM, it is against Colorectal cancer cell lines growth with IC50 values ranging from 11.5 μM to15.3 μM and is against lung, osteosarcoma, prostate and liver cancer cell lines with IC50 values ranging from 11.5 μM to 37.3 μM, respectively[1].BS-181 (0-50 μM; 4 hours) shows inhibition of phosphorylation of the RNA polymerase II C-terminal domain (CTD) at serine 5 (P-Ser5). It down-regulates CDK4 and cyclin D1 expression while does not effect other CDKs and cyclins[1].BS-181 (0-50 μM; 24 hours) shows an increase in cells in G1, accompanied by a reduction in cell numbers in S and G2/M at low concentrations. At higher concentrations, however, cells accumulates in the sub-G1, indicative of apoptosis[1]. Cell Proliferation Assay[1] Cell Line: | ||||||||||||
