Description: | THZ531 is a covalent inhibitor of both CDK12 and CDK13 with IC50s of 158 nM and 69 nM, respectively. |
In Vitro: | The results from Kinase assays demonstrate that THZ531 potently inhibits CDK12 and CDK13 with IC50s of 158 nM and 69 nM, respectively; whereas inhibition of CDK7 and CDK9 is more than 50-fold weaker with IC50s of 8.5 and 10.5 µM, respectively. THZ531 treatment leads to a dramatic and irreversible decrease in Jurkat cell proliferation with an IC50 of 50 nM. FACS cell cycle analysis following treatment with escalating doses of THZ531 displays a dose and time-dependent increase in the number of cells exhibiting sub-G1 content. At 50 nM THZ531, no increase in the percentage of apoptotic cells is observed over DMSO control for the time course of the experiment. Higher doses of THZ531 leads to pronounced Annexin V signal with 30 to 40% annexin V-positively stained cells by 72 hrs. A dramatic reduction in elongating Pol II following THZ531 treatment is also observed[1]. |
