Advances in Pyrazole Based Scaffold as Cyclin-dependent Kinase 2 Inhibitors for the Treatment of Cancer.

The transformation of a normal cell into a tumor cell is one of the initial steps in cell cycle deregulation. The cell cycle is regulated by cyclin-dependent kinases (CDKs) that belong to the protein kinase family. CDK2 is an enchanting target for specific genotype tumors since cyclin E is selective for CDK2 and the deregulation of specific cancer types.
