Biological Activity

CDK inhibitor E9 is a novel CDK inhibitor that can overcomes ABC-mediated resistance of THZ1, functions as a potent, non-covalent inhibitor of CDK9 and a covalent inhibitor of CDK12.
CDK inhibitor E9 does not serve as a substrate for either ABCB1 or ABCG2, while avoiding ABC transporter-mediated efflux.
CDK inhibitor E9 decreases the phosphorylated and total RNAPII in THZ1R NB and lung cancer cells (IC50=8-40 nM), accompanied by decreased MYC and MCL1 expression, exerts its cytotoxic effects through covalent modification of cysteine 1039 of CDK12.
