Background

K03861 is a type II inhibitor of CDK2. The cyclin-dependent kinase holoenzymes contain a catalytic subunit, the Cdk, a family of regulatory subunits, and the cyclins. Cdks are the catalytic subunits of the mammalian heterodimeric serine/threonine kinases progression, Cyclin-dependent kinases (CDKs) play important roles in the cell cycle regulation, transcription, and neuronal function. CDKs are frequently deregulated in some human tumours. The inhibitors targeted CDK are thought to prevent cell proliferation regulating cyclin-CDK complexes. The central role of CDKs in cell cycle regulation makes them a promising target for studying inhibitory molecules that can modify the cell proliferation [1].

K03861 is an aminopyrimidine-phenyl urea inhibitor of CDK2. The type II inhibitor CDK2 cocrystal structure of CDK2 with the inhibitor K03861 revealed a canonical type II binding mode. The type II inhibitors could compete with the binding of cyclins. The residues important for the type II inhibitors may be distant to the ATP binding pockets. The crystal structure of this complex may provide a foundation for the cyclin-competitive CDK2 inhibitors [2].
