CDK9-IN-37

CDK9-IN-37 (Compound 24) is a CDK9 inhibitor with high selectivity, demonstrating an EC50 of 5.5 nM and minimal inhibition of other CDK subtypes. It shows significant antiproliferative activity against acute myeloid leukemia cells MOLM-13, with an IC50 of 0.034 μM. CDK9-IN-37 suppresses CDK9 signaling, reducing RNAP II CTD (Ser2) phosphorylation, downregulating the anti-apoptotic protein McI-1, inducing apoptosis, and causing cell cycle arrest at the G2/M phase. This compound is applicable in the research of acute myeloid leukemia (AML) .
