A series of indenopyrazoles 8 and 9 were designed and synthesized as EGFR tyrosine kinase inhibitors by in silico high-throughput screening. Compounds 8b and 8d showed significant inhibition of A431 cell growth (GI50 = 0.062 and 0.057 μM, respectively). Compounds 8b and 9a showed inhibitory activity toward both EGFR and VEGFR-2 (KDR) tyrosine kinases, whereas 8d inhibited VEGFR-2 tyrosine kinase, exclusively.

The identification of indeno[1,2-c]pyrazol-4-ones as inhibitors of cyclin-dependent kinases (CDKs) has led to the discovery of a series of novel and potent compounds. Herein, we report the effects of substitutions at C3 of the indeno[1,2-c]pyrazol-4-one core with alkyls, heterocycles, and substituted phenyls. Substitutions at the para position of the phenyl ring at C3 were generally well-tolerated; however, larger groups were generally inactive. For alkyls directly attached to C3, longer chain substituents were not tolerated; however, shorter alkyl groups and cyclic alkyls were acceptable. In general, the heterocycles at C3 gave the most potent analogues. One such heterocycle, 24j, was examined in detail and was determined to have a biological profile consistent with CDK inhibition. An X-ray crystal structure of one of the alkyl compounds, 13q, complexed with CDK2 was determined and showed the inhibitor residing in the adenosine 5′-triphosphate pocket of the enzyme.
