Cat.No.S8730

Enitociclib (BAY 1251152) is a potent PTEFb/CDK9 inhibitor with an IC50 value of 3 nM for CDK9 and an at least 50-fold selectivity against other CDKs in enzymatic assays. It binds to and blocks the phosphorylation and kinase activity of CDK9, thereby preventing PTEFb-mediated activation of RNA Pol II and leading to the inhibition of gene transcription of various anti-apoptotic proteins.

Mechanism of Action

Targets/IC₅₀/Ki	CDK9 (Cell-free assay) 3 nM
In vitro	Enitociclib (BAY 1251152) (compound 2) significantly inhibits CDK9 and CDK2 with IC50 of 3 nM and 360 nM, respectively, and shows cellular potency in MOLM13 with IC50 of 29 nM.
In vivo	Enitociclib (BAY 1251152) demonstrates excellent efficacy upon i.v. treatment in xenograft models (e.g. MOLM13) in mice and rats. It is currently being evaluated in Phase I studies to determine the safety, tolerability, pharmacokinetics and initial pharmacodynamic biomarker response in patients with advanced cancer.
