| abstract |
The present invention relates to a compound of the following general formula (I): R 1 —NH—CH(R 2 )—P(═O)(OR 3 )—CH 2 —C(R 4 )(R 5 )—CONH—CH(R 6 )—COOR 7 (I) or a pharmaceutically acceptable salt of the latter, an isomer or a mixture of isomers in any proportions, especially a mixture of enantiomers, and in particular a racemic mixture, for which R 1 represents a —C(═O)—O—C(R 8 )(R 9 )—OC(═O)—R 10 group; R 2 represents an optionally substituted hydrocarbon-based chain, an aryl or heteroaryl group or a methylene group substituted by a heterocycle; R 3 represents a hydrogen atom or a —C(R 12 )(R 13 )—OC(═O)—R 14 group; R 4 and R 5 form, together with the carbon that bears them, a saturated hydrocarbon-based ring or an optionally substituted piperidine ring or R 4 represents a hydrogen atom and R 5 represents a phenyl or a benzyl that is optionally substituted, a heteroaromatic ring or a methylene group substituted by a heterocycle; R 6 represents an optionally substituted hydrocarbon-based chain or a phenyl or a benzyl that is optionally substituted; and R 7 represents a hydrogen atom or a benzyl, alkyl, heteroaryl, alkylheteroaryl, —CHMe—COOR 18 , —CHR 19 —OC(═O)OR 20 and —CHR 19 —OC(═O)OR 20 group. The present invention also relates to the use of these compounds as a medicinal product, and in particular for the treatment of pain, more advantageously neuropathic and neuroinflammatory pain, to their method of synthesis and also to the compositions containing them. |
