Claim:
A compound of general formula (I): wherein: (2) and (3) indicate two of the possible asymmetric centers in the molecule; X is a hydrogen atom, a primary amine NH 2 or secondary amine NHR wherein R is an alkyl or arylalkyl group; R 1 is: a hydrogen atom, a group S-R′ in which R′ represents an alkyl, aryl, (aryl)alkyl, cycloalkyl or (cycloalkyl)alkyl group, or one of these groups substituted with at least one fluorine or other halogen atoms, or with a CF 3 —; or a group S—CH[CH(R 2 )X]—CO—R 3 with R 2 and R 3 as defined below; R 2 is an alkenyl, alkynyl, cycloalkyl, (cycloalkyl)alkyl, aryl or (aryl)alkyl group, substituted with a COOH or COOR″ group, with R″ being an alkyl, aryl, (aryl)alkyl, cycloalkyl or (cycloalkyl)alkyl group, substituted with at least one fluorine or other halogen atom, or with a CF 3 group; R 3 is: a group NHR 4 in which R 4 represents an alkyl, cycloalkyl, (cycloalkyl)alkyl, aryl, (aryl)alkyl, heteroaryl or (heteroaryl)alkyl group; or an amino acid residue or a peptide chain (AA) n R 5 in which: n is equal to 1 or 2 R 5 is OH, NH 2 or NHR′″ with R′″ being an alkyl, cycloalkyl, (cycloalkyl)alkyl, aryl, (aryl)alkyl, heteroaryl or (heteroaryl )alkyl group, AA is an amino acid residue of formula (II) N(R 6 )—(CH 2 ) m —CH(R 7 )—(CH 2 ) p —CO (II) in which: m=0 or 1, p=0 or 1, R 6 is a hydrogen atom, a methyl or another alkyl group; and R 7 is an alkyl, (aryl)alkyl or (heteroaryl)alkyl group, or one of these groups substituted with one or more halogen atoms and/or one or more group(s) selected from OH, OCH 3 or other alkoxy or CF 3 , it being understood that, when n is equal to 2, the two amino acid residues AA may be identical or different; and the addition salts or enantiomeric forms thereto.
