This study evaluates the efficacy of two newly developed selective CDK9 inhibitors (CDK9i) across a panel of TNBC cell lines. MDA-MB-453, MFM-223, MDA-MB-468 and MDA-MB-231 TNBC cells were treated with increasing concentrations of two novel and highly selective CDK9 inhibitors and the effect on proliferation, apoptosis and expression of CDK9 targets determined. MDA-MB-453 and -468 cells showed significant growth inhibition with as little as 150 nM of CDK9i, evident 3 days afte...
