The present invention relates to a compound of the following general formula (I): R1—NH—CH(R2)—P(═O)(OR3)—CH2—C(R4)(R5)—CONH—CH(R6)—COOR7 (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 R1 represents a —C(═O)—O—C(R8)(R9)—OC(═O)—R10 group; R2 represents an optionally substituted hydrocarbon-based chain, an aryl or heteroaryl group or a methylene group substituted by a heterocycle; R3 represents a hydrogen atom or a —C(R12)(R13)—OC(═O)—R14 group; R4 and R5 form, together with the carbon that bears them, a saturated hydrocarbon-based ring or an optionally substituted piperidine ring or R4 represents a hydrogen atom and R5 represents a phenyl or a benzyl that is optionally substituted, a heteroaromatic ring or a methylene group substituted by a heterocycle; R6 represents an optionally substituted hydrocarbon-based chain or a phenyl or a benzyl that is optionally substituted; and R7 represents a hydrogen atom or a benzyl, alkyl, heteroaryl, alkylheteroaryl, —CHMe-COOR18, —CHR19—OC(═O)R20 and —CHR19—OC(═O)OR20 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.
