CA 2336968

The invention is related to compounds of general formula (I), wherein R is methyl, ethyl, n-propyl, iso-propyl, n-butyl or allyl; R' is methyl, methoxy, fluoro, chloro, bromo, trifluoromethyl, or OCH x F y, wherein x = O - 2, y = 1 - 3 with the proviso that x + y = 3; R" is hydrogen, fluoro or chloro; with the proviso that R" is fluoro or chloro only when R' is fluoro; R4 is hydrogen or pharmaceutically acceptable inorganic or organic cations; R5 is ethyl, n-propyl, iso-propyl, methoxy, ethoxy, chloro, bromo, trifluoromethyl, OCH x F y, or OCH2CH x F y wherein x = 0 - 2, y = 1 - 3 with the proviso that x + y = 3; R6 is hydrogen; or R5, and R6 taken together are methylenedioxy; and any tautomer thereof. The invention also relates to pharmaceutical compositions containing a compound of general formula (I) together with a pharmaceutically acceptable carrier. Included are also processes for the preparation of the compounds of formula (I), as well as methods for the treatment of mammals suffering from diseases resulting from autoimmunity and pathological inflammation by administering of a compound having formula (I) to said mammal.

L'invention concerne des composés de formule générale (I), dans laquelle R représente un méthyle, éthyle, n-propyle, iso-propyle, n-butyle ou allyle; R' représente un méthyle, méthoxy, fluoro, chloro, bromo, trifluorométhyle ou OCHxFy où x = 0 - 2, y = 1 - 3 à condition que x + y = 3; R'' représente un hydrogène, fluoro ou chloro à condition que R'' représente un fluoro ou chloro uniquement lorsque R' représente un fluoro ou chloro; R4 représente un hydrogène ou des cations inorganiques ou organiques pharmaceutiquement acceptables; R5 représente un éthyle, n-propyle, iso-propyle, méthoxy, éthoxy, chloro, bromo, trifluorométhyle, OCHxFy ou OCH2CHxFy où x = 0 - 2, y = 1 - 3 à condition que x + y = 3; R6 représente un hydrogène; ou R5 et R6, pris ensemble, représentent un méthylènedioxy; et leur tautomère. L'invention concerne aussi des compositions pharmaceutiques contenant un composé de formule générale (I) et un support pharmaceutiquement acceptable. Font aussi l'objet de cette invention les procédés de préparation des composés de formule (I) et les procédés de traitement des mammifères souffrant de maladies dérivées de l'auto-immunité et d'inflammations pathologiques par l'administration d'un composé de formule (I) audit mammifère.
