2-Aminoquinazoline inhibitors of cyclin-dependent kinases

The inhibition of cyclin-dependent kinase 4 (Cdk4) causes cell cycle arrest and restores a checkpoint that is absent in the majority of tumor cells. Compounds that inhibit Cdk4 selectively are targeted for treating cancer. Appropriate substitution of 2-aminoquinazolines is demonstrated to produce high levels of selectivity for Cdk4 versus closely related serine-threonine kinases.
