    A 5-aryl-1H-pyrazole molecular scaffold was designed to ligate the ATP binding site of cyclin dependent kinase 2 (CDK2) on the basis of crystallographic information. A search of the compound collection of Novartis using this scaffold as substructure query led to the identification of PKF049-365 as a representative of a new class of inhibitors of the cell cycle kinases CDK1/2. The three-dimensional structure of CDK2 in complex with PKF049-365 was subsequently determined by protein crystallography and refined to 1.53 A resolution. The X-ray analysis confirmed the binding mode expected from the design hypothesis. In addition, it revealed an alternative binding orientation involving a second tautomeric form of the inhibitor that was not envisaged during the design stage.
