Patent

CA 2367866

This invention concerns a bicyclic compound of Formula (I), wherein: G is N, CH or C(CN); ring X is a 5- or 6-membered fused heteroaryl ring which contains 1, 2, or 3 heteroatoms selected from oxygen, sulphur and nitrogen; m is 0 - 2; R1 is a group such as hydroxy, halo, trifluoromethyl, cyano, mercapto, nitro, amino, carboxy and carbamoyl; each of R2 and R3 is hydrogen, halo, C1-6alkyl, C2-6alkenyl or C2-6alkynyl; R4 is a group such as hydrogen, hydroxy, C1- 6alkyl, C1-6alkoxy, amino and N-C1-6alkylamino; R5 is a group such as hydrogen, halo, trifluoromethyl, cyano, nitro, amino and hydroxy, and q is 0 - 4; or a pharmaceutically acceptable salt or an in vivo cleavable ester thereof; processes for its preparation, a pharmaceutical composition containing it and its use in the treatment of diseases or medical conditions mediated by cytokines.

La présente invention concerne un composé bicyclique représenté par la formule (I) dans laquelle: G désigne N, CH ou C(CN); le cycle X désigne un cycle hétéroaryle condensé à 5 ou 6 chaînons contenant 1, 2, ou 3 hétéroatomes sélectionnés dans le groupe formé par l'oxygène, le soufre et l'azote; m désigne un nombre de 0 à 2 R?1¿ désigne un groupe tel que hydroxy, halo. trifluorométhyle, cyano, mercapto, nitro, amino, carboxy et carbamoyle; R?2¿ et R?3¿ désignent chacun un hydrogène, un halo, un alkyle en C¿1-6?, un alcényle en C¿2-6? ou un alkynyle en C¿2-6?; R?4¿ désigne un groupe tel que hydrogène, hydroxy, alkyle en C¿1-6?, alcoxy en C¿1-6?, amino et N-C¿1-6? alkylamino; R?5¿ désigne un groupe tel que hydrogène, halo, trifluorométhyle, cyano, nitro, amino et hydroxy; Et q désigne un nombre de 0 à 4. L'invention concerne également un sel de ce composé acceptable du point de vue pharmaceutique, ainsi qu'un ester de ce composé pouvant être clivé in vivo; l'invention concerne aussi ses procédés de préparation, une composition pharmaceutique le contenant et son utilisation pour le traitement de maladies ou d'états pathologiques associés aux cytokines.
