Quinazolines have been identified as inhibitors of CDK4/D1 and CDK2/E. Aspe
cts of the SAR were investigated using solution-phase. parallel synthesis.
An X-ray crystal structure was obtained of quinazoline 51 bound in CDK2 and
key interactions within the ATP binding pocket are defined. (C) 2001 DuPon
