Phenylacetamido-pyrazoles and, more particularly, N-(5-cycloalkyl-1H-pyrazol-3-yl)phenylacetamido derivatives, optionally further substituted as reported in the description; or pharmaceutically acceptable salts thereof; are useful in the treatment of cell proliferative disorders, e.g. cancer, associated with an altered cell cycle dependent kinase activity.
Inhibitors of cyclin-dependent kinases (CDK) such as CDK2/cyclin A-E are currently undergoing clinical trials to verify their potential as new anticancer agents. In a previous article we described the lead discovery process of a 3-aminopyrazole class of CDK2/cyclin A-E inhibitors. The endpoint of this process was PNU-292137, a compound endowed with in vivo antitumor activity in a mouse tumor xenograft
