CDK9-IN-47
CDK9-IN-47 is an orally active and selective CDK9 inhibitor with an IC50 of 1.4 nM. CDK9-IN-47 inhibits tumor cell proliferation, migration and invasion, and induces apoptosis. CDK9-IN-47 can be used for the research of triple-negative breast cancer.

Biological Activity
CDK9-IN-47 (compound HS34) (72 h) potently inhibits the proliferation of various breast cancer cell lines, and exhibits no cytotoxicity against normal cardiomyocytes and hepatocytes after 72 h of treatment (GI50 > 10 μM)[1].
CDK9-IN-47 (0.1-1.0 μM; 24 h) ablates the clonogenic potential of MDA-MB-231 and 4T1 triple-negative breast cancer (TNBC) cells in a dose-dependent manner[1].
CDK9-IN-47 (0.1-3.0 μM; 8-24 h) induces dose-dependent apoptosis and inhibits cell migration and invasion abilities in MDA-MB-231 and 4T1 triple-negative breast cancer (TNBC) cells[1].
CDK9-IN-47 (0.1-1.0 μM; 8 h) selectively inhibits CDK9-driven transcription processes in MDA-MB-231 and 4T1 triple-negative breast cancer (TNBC) cells, which is characterized by decreased levels of p-Ser2 CTD, downregulated expression of c-Myc and Mcl-1, and reduced cyclin T1 levels[1].
