Background:

Dinaciclib is a potent cyclin-dependent kinase (CDK) inhibitor with IC50s for CDK2, CDK5, CDK1 and CDK9 at 1 nM, 1 nM, 3 nM, and 4 nM, respectively. [1] It is in phase I or II clinical trials for various cancers.

Dinaciclib interacts with the acetyl-lysine recognition site of bromodomains. [2] Inhibition of CDK 1 suppresses Rb phosphorylation, leading to cell cycle arrest and apoptosis. [3]

Dinaciclib is active against a broad spectrum of human tumor cell lines in vitro and in vivo. It has great potential to improve cancer chemotherapy.
