Patent

CA 2200871

The invention concerns aniline derivatives of formula (I) wherein m is 1, 2 or 3 and each R1 includes halogeno, hydroxy, amino, hydroxyamino, ureido, trifluoromethoxy and (1-4C)alkyl; n is 0, 1, 2 or 3 and each R2 includes halogeno, trifluoromethyl, hydroxy, amino, nitro, cyano and (1-4C)alkyl; X is a group of the formula CO, C(R3)2, CH(OR3), C(R3)2-C(R3)2, C(R3)-C(R3), C=C, CH(CN), O, S, SO, SO2, CONR3, SO2NR3, NR3CO, NR3SO2, OC(R3)2, SC(R3)2, C(R3)2O or C(R3)2S wherein each R3 is independently hydrogen or (1-4C)alkyl; and Q is a phenyl or naphthyl group or a 5- or 6-membered heteroaryl moiety containing 1, 2 or 3 heteroatoms selected from oxygen, nitrogen and sulphur, or a pharmaceutically- acceptable salt thereof; processes for their preparation, pharmaceutical compositions containing them, and the use of the receptor tyrosine kinase inhibitory properties of the compounds in the treatment of proliferative disease such as cancer.

Dans cette formule, m vaut 1, 2 ou 3 et chaque R<1> représente halogéno, hydroxy, amino, hydroxyamino, uréido, trifluorométhoxy et (1-4C) alkyle; n vaut 0, 1, 2 ou 3 et chaque R<2> représente halogéno, trifluorométhyle, hydroxy, amino, nitro, cyano et (1-4C) alkyle; X est un groupe de la formule CO, C(R<3>)2, CH(OR<3>), C(R<3>)2-C(R<3>)2, C(R<3>)=C(R<3>), C=C, CH(CH), O, S, SO, SO2, CONR<3>, SO2NR<3>, NR<3>CO, NR<3>CO2, OC(R<3>)2, SC(R<3>)2, C(R<3>)2O ou C(R<3>)2S, où chaque R<3> est indépendamment hydrogène ou (1-4C) alkyle; et Q est un groupe de phényle ou de naphthyle ou une fraction hétéroarylique à 5 ou 6 éléments comprenant 1, 2 ou 3 hétéroatomes choisis parmi l'oxygène, l'azote et le soufre. L'invention concerne également un sel de la présente formule qui soit acceptable sur le plan pharmaceutique; des procédés pour leur préparation, des compositions pharmaceutiques à base de ces substances, et l'utilisation des propriétés inhibitrices du récepteur de tyrosine-kinase des composés dans le traitement de maladies à évolution chronique telles que le cancer.
