Patent

CA 2497632

The invention relates to compounds having formula (I), which are characterised in that: X denotes oxygen or sulphur; Y denotes oxygen, -NH or -N(C¿1?-C¿6?)alkyl; R¿a? denotes hydrogen, halogen, (C¿1?-C¿3?)alkyl, hydroxy, or (C¿1?-C¿3?)alkoxy; R¿b? denotes hydrogen, halogen, or (C¿1?-C¿3?)alkyl; A denotes phenyl, pyridyl, (C¿5?-C¿6?)cycloalkyl or (C¿5?-C¿6?)cycloalkenyl; R¿1? and R¿2? each denote a group selected from hydrogen, halogen, cyano, nitro, halogenoalkyl, halogenoalkoxy, alkyl, alkenyl, alkynyl, -OR¿4?, -NR¿4?R¿5?, -S(O)¿n?R¿4?, -C(O)R¿4?, -C0¿2?R¿4?, -O-C(O)R¿4?, -C(O)NR¿4?R¿5?, -NR¿5?-C(O)R¿4?, -NR¿5?-S0¿2?R¿4?, -T-CN, -T-OR¿4?, -T-OCF¿3?, -T-NR¿4?R¿5?, -T-S(O)¿n?R¿4?, -T-C(O)R¿4?, -T-C0¿2?R¿4?, -T-O-C(O)R¿4?, -T-C(O)NR¿4?R¿5?, -T-NR¿4?-C(O)R¿5?, -T-NR¿4?-S0¿2?R¿5?, -R¿6?, and -T-R¿6?, wherein n, T, R¿4?, R¿5? and R¿6? are as defined in the description; and R¿3? denotes a -R¿7? or -U-R¿11 ?group, wherein R¿7? denotes hydrogen, alkyl, aryl, cycloalkyl or heterocycle, U denotes a linear or branched alkylene chain and R¿11? is as defined in the description. The invention also relates to the optical isomers thereof or the addition salts of same having a pharmaceutically-acceptable base or acid. The invention further relates to the use of said compounds as an inhibitor of metalloproteinase and, more specifically, of metalloproteinase-12.
