Background:

LDC000067 (LDC067) is a novel specific inhibitor of CDK9 with IC50 value of 44 ± 10 nM [1].

Cyclin-dependent kinase 9 (CDK9) is a cyclin-dependent kinase. CDK9 and cyclin T form the positive transcription elongation factor b (P-TEFb) complex for RNA polymerase II and functions by phosphorylating the C-terminal domain of the largest subunit of RNA polymerase II [1].

LDC000067 (LDC067) is a novel and highly specific CDK9 inhibitor. LDC000067 exhibited selectivity for CDK9 over other CDKs in the range of 55-fold (vs. CDK2) to over 230-fold (vs. CDK6 and CDK7). LDC067 also inhibited transcription in a dose-dependent and ATP-competitive manner. In whole cells, LDC000067 induced the tumor suppressor protein p53 activation and apoptosis. LDC000067 also selectively reduced short-lived mRNAs, including those that encode regulators of apoptosis and proliferation such as MYC and MCL1 [1].
