Patent ID: 8362057

Claim:
A compound of the formula (I): in which R represents a group chosen from: —OH, —OR e and —NR a R b ; and R a and R b , which may be identical or different, are independently chosen from a hydrogen atom and a radical Z, or alternatively may form, together with the nitrogen atom that bears them, a saturated or unsaturated 5- or 6-membered ring optionally containing from 1 to 3 heteroatoms, the said ring optionally being substituted by 1 to 3 groups chosen from Y; and R e represents a (C 1 -C 8 )alkyl radical, optionally substituted by one or more groups independently chosen from halogen, (C 1 -C 8 )alkyl, (C 1 -C 8 )alkoxy, (C 3 -C 8 )cycloalkyl and (C 6 -C 14 )aryl; and R 1 represents one of the following groups: and R 2 represents a substituted or unsubstituted aryl radical; and -A-X-D- represents a group in which, independently between A, X and D: A represents a divalent group obtained after abstraction of a hydrogen atom from a (C 1 -C 20 )alkyl, optionally substituted by one or more groups chosen from Y; and D represents a bond; and X represents a divalent group obtained after abstraction of a hydrogen atom from a monovalent radical chosen from: (C 6 -C 14 ) aryl, which may itself be optionally substituted by one or more groups chosen from Y; (C 5 -C 14 )heteroaryl, which may itself be optionally substituted by one or more groups chosen from Y, this heteroaryl group comprising one or more heteroatoms chosen from N, O and S; (C 3 -C 8 )cycloalkyl, which may itself be optionally substituted by one or more groups chosen from Y; (C 4 -C 8 )cycloalkenyl, which may itself be optionally substituted by one or more groups chosen from Y; and (C 3 -C 8 )heterocycloalkyl, which may itself be optionally substituted by one or more groups chosen from Y, this heterocycloalkyl group comprising one or more heteroatoms chosen from N, O and S; and Y represents a radical chosen from hydroxyl, thio, halogen, cyano, trifluoromethoxy, trifluoromethyl, carboxyl, carboxymethyl or carboxyethyl, (C 1 -C 8 )alkyl, (C 1 -C 8 )alkoxy, (C 1 -C 8 )alkylamino, (C 6 -C 14 )aryl, (C 6 -C 14 )aryloxy, (C 6 -C 14 )aryl(C 1 -C 8 )alkoxy, amino, oxo and carbamoyl; and Z represents a group chosen from: (C 1 -C 20 )alkyl optionally substituted by one or more groups chosen from Y; (C 2 -C 20 )alkenyl, optionally substituted by one or more groups chosen from Y; (C 6 -C 14 )aryl or (C 6 -C 14 )aryl(C 1 -C 20 )alkyl, the aryl group of each of these groups itself optionally being substituted by one or more groups chosen from Y; and (C 6 -C 14 )heteroaryl or (C 6 -C 14 )heteroaryl(C 1 -C 20 )alkyl, the heteroaryl group of each of these groups itself optionally being substituted by one or more groups chosen from Y, this heteroaryl group comprising one or more heteroatoms chosen from N, O and S, or the possible tautomeric forms thereof and the possible enantiomers, diastereoisomers, epimers and organic or mineral salts thereof.
