Patent ID: 8288433

Claim:
A compound selected from those of formula (I): wherein: R 1 represents a hydrogen atom or a â€”COOR group wherein R represents a linear or branched (C 1 -C 6 )alkyl group or an aryl-(C 1 -C 6 )alkyl group in which the alkyl moiety may be linear or branched; R 2 represents a group G or a linear or branched (C 1 -C 6 )alkyl group substituted by a group G, wherein G represents a â€”(CH 2 ) n -A-(CH 2 ) m â€”Bâ€”(CR 4 R 5 ) p â€”(CH 2 ) o â€”R 6 group wherein: n is 0, 1, 2 or 3, m is 0, 1, 2 or 3, p is 0 or 1, o is 0, 1 or 2, R 4 and R 5 , which may be identical or different, each represent a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group, wherein one of the groups â€”CH 2 â€” or â€”CR 4 R 5 â€” of the G chain may equally be replaced, if desired, by a phenylene, â€”PhC(O)â€” or â€”PhC(O)Oâ€” group, wherein Ph denotes phenyl, A and B, which may be identical or different, each represent a bond, a nitrogen atom or a group: wherein R 7 represents a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group, and R 6 represents a group wherein R 8 , R 9 and R 10 , which may be identical or different, each represent a hydrogen atom or a linear or branched (C 1 -C 6 )alkyl group unsubstituted or substituted by an amino group, or R 8 and R 9 together form a linear or branched (C 1 -C 6 )alkylene chain; and R 3 represents a hydrogen atom, a linear or branched (C 1 -C 6 )alkyl group or an NO 2 group, its enantiomers, diastereoisomers, and addition salts thereof with a pharmaceutically acceptable acid or base.
