Uses
A purine derivative which inhibits cyclin-dependent kinases and induces G1 arrest.
Definition
ChEBI: Olomoucine is a 9H-purine that is substituted by a (2-hydroxyethyl)nitrilo, benzylnitrilo and a methyl group at positions 2,6 and 9, respectively. It is a cyclin-dependent kinase inhibitor. It has a role as an EC 2.7.11.22 (cyclin-dependent kinase) inhibitor. It is a member of 2,6-diaminopurines and a member of ethanolamines.
Biological Activity
Cyclin-dependent kinase inhibitor that competes for the ATP binding site of the kinase. Selectively inhibits cdc2/cyclin B (IC 50 = 7 μ M), cdk2/cyclin A (IC 50 = 7 μ M), cdk2/cyclin E (IC 50 = 7 μ M), cdk/p35 kinase (IC 50 = 3 μ M) and ERK1/MAP kinase (IC 50 = 25 μ M). Arrests human fibroblasts in the G1 phase.
Biochem/physiol Actions
Olomoucine is a purine derivative which inhibits cyclin-dependent kinases and induces G arrest.
Enzyme inhibitor
This ATP site-competitive purine derivative (FW = 298.35 g/mol; CAS 101622-51-9), systematically named 6-benzylamino-2-[2-hydroxyethylamino]- 9-methylpurine, is a potent inhibitor of cyclin-dependent kinases, with an IC50 value of 7 μM for both cdk1 and cdk2 and an IC50 value of 3 μM for cdk5, arresting cells in G1. Olomoucine also inhibits cytokinin 7b-glucosyltransferase.
