CA 2651681

The present invention relates to a novel class of aryl-fused spirocyclic compounds. These compounds can inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells. The compounds of the invention may also be useful in the prevention and treatment of TRX-mediated diseases, such as autoimmune, allergic and inflammatory diseases, and in the prevention and/or treatment of diseases of the central nervous system (CNS), such as neurodegenerative diseases. The present invention further provides pharmaceutical compositions comprising the compounds of the instant invention and safe dosing regimens of these pharmaceutical compositions, which are easy to follow, and which result in a therapeutically effective amount of these compounds in vivo.

La présente invention concerne une nouvelle catégorie de composés spirocycliques fusionnés à aryle. Ces composés peuvent inhiber l'histone désacétylase et leur utilisation est appropriée pour induire de manière sélective la différenciation terminale, stopper la croissance cellulaire et/ou induire l'apoptose des cellules néoplasiques, pour ainsi inhiber la prolifération de ces cellules. Ainsi, les composés de l'invention sont utiles pour traiter un patient présentant une tumeur qui se caractérise par la prolifération de cellules néoplasiques. Les composés de l'invention peuvent également être utiles pour prévenir et traiter des troubles dans lesquels la thiorédoxine (TRX) joue un rôle, tels que des troubles auto-immuns, allergiques et inflammatoires, et pour prévenir et/ou traiter des troubles du système nerveux central (SNC) tels que des troubles de neurodégénérescence. L'invention a également pour objet des compositions pharmaceutiques comprenant les composés de l'invention ainsi que des schémas posologiques inoffensifs de ces compositions pharmaceutiques qui sont faciles à suivre et qui conduisent à une administration thérapeutiquement efficace de ces composés in vivo.
