Patent

CA 2422377

This invention describes novel pyrazole compositions comprising a pharmaceutically acceptable carrier and a compound of formula VIII, wherein Z1 is N or C-R9, Z2 is N or CH, and Z3 is N or C-Rx, provided that one of Z1 and Z3 is nitrogen; G is Ring C or Ring D; Ring C is selected from a phenyl, pyridinyl, pyrimidinyl, pyridazinyl, pyrazinyl, or 1,2,4-triazinyl ring, wherein said Ring C has one or two ortho substitutents independently selected from -R1; Ring D is a 5-7 membered monocyclic ring or 8-10 membered bicyclic ring selected from aryl, heteroaryl, heterocyclyl or carbocyclyl; and Rx, R1, R2, R2', R3 and R9 are as described inthe specification. The compounds are useful as protein kinase inhibitors, especially as inhibitors of aurora-2 and GSK-3, for treating diseases such as cancer, diabetes and Alzheimer's disease.

L'invention concerne de nouvelles compositions de pyrazole qui contiennent un excipient pharmaceutiquement acceptable et un composé représenté par la formule VIII, dans laquelle Z?1¿ représente N ou C-R?9¿, Z?2¿ représente N ou CH, et Z?3¿ représente N ou C-R?x¿, à condition que Z?1¿ ou Z?3¿ représente azote ; G représente le noyau C ou le noyau D ; le noyau C est sélectionné dans le groupe comprenant un noyau phényle, pyridinyle, pyrimidinyle, pyridazinyle, pyrazinyle, ou 1,2,4-triazinyle, ce noyau C comportant un ou deux substituants en ortho sélectionnés indépendamment dans le groupe comprenant -R?1¿; le noyau D est un noyau monocyclique doté de 5 à 7 chaînons ou un noyau bicyclique doté de 8 à 10 chaînons, sélectionné dans le groupe comprenant aryle, hétéroaryle, hétérocyclyle ou carbocyclyle ; et R?x¿, R?1¿, R?2¿, R?2'¿, R?3¿ et R?9¿ sont tels que décrits dans la spécification. Ces composés sont utiles comme inhibiteurs de protéine kinase, notamment comme inhibiteurs d'aurora-2 et de GSK-3, pour traiter des maladies telles que le cancer, le diabète et la maladie d'Alzheimer.
