3-Aminopyrazole inhibitors of CDK2/cyclin A as antitumor agents. 1. Lead finding.
P.Pevarello, M.G.Brasca, R.Amici, P.Orsini, G.Traquandi, L.Corti, C.Piutti, P.Sansonna, M.Villa, B.S.Pierce, M.Pulici, P.Giordano, K.Martina, E.L.Fritzen, R.A.Nugent, E.Casale, A.Cameron, M.Ciomei, F.Roletto, A.Isacchi, G.Fogliatto, E.Pesenti, W.Pastori, A.Marsiglio, K.L.Leach, P.M.Clare, F.Fiorentini, M.Varasi, A.Vulpetti, M.A.Warpehoski.
Abnormal proliferation mediated by disruption of the normal cell cycle mechanisms is a hallmark of virtually all cancer cells. Compounds targeting complexes between cyclin-dependent kinases (CDK) and cyclins, such as CDK2/cyclin A and CDK2/cyclin E, and inhibiting their kinase activity are regarded as promising antitumor agents to complement the existing therapies. From a high-throughput screening effort, we identified a new class of CDK2/cyclin A/E inhibitors. The hit-to-lead expansion of this class is described. X-ray crystallographic data of early compounds in this series, as well as in vitro testing funneled for rapidly achieving in vivo efficacy, led to a nanomolar inhibitor of CDK2/cyclin A (N-(5-cyclopropyl-1H-pyrazol-3-yl)-2-(2-naphthyl)acetamide (41), PNU-292137, IC50 = 37 nM) with in vivo antitumor activity (TGI > 50%) in a mouse xenograft model at a dose devoid of toxic effects.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time.
