Item Type: Article


Irreversible inhibitors that modify cysteine or lysine
residues within a protein kinase ATP binding site
offer, through their distinctive mode of action, an
alternative to ATP-competitive agents. 4-((6-(Cyclohexylmethoxy)-9H-purin-2-yl)amino)benzenesulfonamide (NU6102) is a potent and selective ATP-competitive inhibitor of CDK2 in which the sulfonamide
moiety is positioned close to a pair of lysine residues.
Guided by the CDK2/NU6102 structure, we designed
9H-purin-2-amine (NU6300), which binds covalently to CDK2 as shown by a co-complex crystal
structure. Acute incubation with NU6300 produced
a durable inhibition of Rb phosphorylation in SKUT1B cells, consistent with it acting as an irreversible
CDK2 inhibitor. NU6300 is the first covalent CDK2 inhibitor to be described, and illustrates the potential
of vinyl sulfones for the
