CA 2329703

This invention provides bicyclic heterocycles that are useful for treating cell proliferative disorders, such as cancer and restenosis, as well as angiogenesis and atherosclerosis. We have now discovered a group of bicyclic compounds that are potent inhibitors of cyclin-dependent kinases (cdks), growth factor-mediated kinases, and non- receptor kinases. The compounds are readily synthesized and can be administered by a variety of routes, including orally, and have sufficient bioavailability for clinical use. This invention provides compounds of Formula (I), where Z is N or CH; G is N or CH; W is NH, S, SO, or SO2, R1 includes phenyl and substituted phenyl, R2 includes alkyl and cycloalkyl, R3 includes alkyl and hydrogen, R8 and R9 include hydrogen and alkyl, and the pharmaceutically acceptable salts thereof. This invention also provides pharmaceutical formulations comprising a compound of Formula (I) together with a pharmaceutically acceptable carrier, diluent, or excipient therefor.

La présente invention concerne des hétérocycles bicycliques utiles aussi bien dans le traitement de troubles dus à une prolifération cellulaire, tels que le cancer et la resténose, que dans ceux relatifs à l'angiogénèse et à l'athérosclérose. Ces composés bicycliques sont de puissants inhibiteurs de kinases dépendantes de la cycline (cdks), de kinases dépendantes du facteur de croissance, et de kinases non réceptrices. Les composés sont facilement synthétisés et peuvent être administrés par des voies différentes, y compris orale, et ils possèdent une biodisponibilité suffisante pour un usage clinique. L'invention concerne des composés et leurs sels, acceptables sur le plan pharmaceutique, de formule (I), dans laquelle Z est un N ou un CH; G est un N ou un CH; W est un NH, un S, un SO, ou un SO2, R<1> comprend un phényle et un phényle substitué; R<2> comprend un alkyle et un cycloalkyle; R<3> comprend un alkyle et un hydrogène, R<8> et R<9> comprennent un hydrogène et un alkyle. Cette invention concerne aussi des formulations pharmaceutiques qui comprennent un composé de formule (I), et un support acceptable sur le plan pharmaceutique, un diluant ou un excipient.
