Patent

CA 2148361

The invention relates to heterocyclic carbamates of formula (I) in which X denotes a nitrogen atom or the group CR4 and Y denotes a nitrogen atom or the group CR5, where R2 and R3 independently of one another stand for radicals of the following meaning: hydrogen atoms, C1- to C6- lower alkyl radicals, C1- to C6- lower alkoxy radicals, C1- to C6- lower alkylthio radicals, halogen atoms, nitro groups, hydroxyl groups, trifluoromethyl radicals, cyano radicals, sulpho radicals, C1- to C6- lower alkylsulphonyl groups, carboxylic acid groups, C1- to C6- lower alkoxycarbonyl radicals, C1- to C6- lower alkoxycarbonyloxy radicals, acetamido radicals, benzamido radicals or the group -N(R6)R7, m and n independently of one another stand for a hydrogen atom or a C1- to C6 lower alkyl radical, and in which R1, R4 and R5 have the meanings given in the description; their use as antithrombotics and as inhibitors of enzymes breaking down connective tissue, in particular granulocyte elastase.

L'invention se rapporte à des carbamates hétérocycliques de formule (I) dans laquelle X représente un atome d'azote ou le groupe CR4, Y représente un atome d'azote ou le groupe CR5, R?2¿ et R?3¿ représentent indépendamment l'un de l'autre des radicaux ayant la notation suivante : atomes d'hydrogène, radicaux alcoyle inférieur en C¿1? à C¿6?, radicaux alcoxy inférieur en C¿1? à C¿6?, radicaux alkylthio inférieur en C¿1? à C¿6?, atomes d'halogène, groupes azote, groupes hydroxyles, radicaux trifluorométhyle, radicaux cyano, radicaux sulfo, groupes alkylsulfonyle inférieur en C¿1? à C¿6?, groupes acide carboxylique, radicaux alcoxycarbonyle inférieur en C¿1? à C¿6?, radicaux alcoxycarbonyloxy inférieur en C¿1? à C¿6?, radicaux acétamido, benzamido ou le groupe -N(R6)R7; m et n représentent indépendamment l'un de l'autre un atome d'hydrogène ou un radical alcoyle inférieur en C¿1? à C¿6?, et R?1¿, R?4¿ et R?5¿ ont les notations données dans la description. L'invention concerne également l'utilisation de ces carbamates en tant agents antithrombotiques et en tant qu'inhibiteurs des enzymes de dislocation du tissu conjonctif, en particulier de la granulocyte-élastase.
