Patent ID: 8546402

Claim:
A compound of formula 1 wherein: R1 represents one or more identical or different substituent(s), each representing, independently, a hydrogen atom or a halogen atom, or a C 1-4 alkoxy group or an OH group, or a C 1-4 alkyl group or an —O(CH 2 ) n O— group in which n=1 or 2; R2 represents a hydrogen atom or a C 1-4 alkyl group; A and B represent, independently, either a nitrogen atom or a carbon atom; R3 represents a hydrogen atom or one or more identical or different substituent(s) selected from the group consisting of: a halogen atom, a C 1-4 alkyl group, a C 1-4 alkoxy or C 1-4 thioalkoxy group, an —O(CH 2 ) n O— group in which n=1 or 2, an NO 2 group, an NHSO 2 R4 group, an NHR5 group, an OH group, a C 1-4 haloalkyl group, a CN group, a C 1-4 alkoxycarbonyl group, a C 1-4 alkylcarbonyl group, a C 1-4 hydroxyalkyl group and a benzyl or phenyl substituent optionally substituted by a C 1-4 alkoxy or a C 1-4 alkyl group or a halogen atom, or R3 constitutes a ring fused with the benzene ring carrying it, selected from the group consisting of a naphthalene, an indole, a benzimidazole, a carbostyril, a benzoxazolone and a benzimidazolone; R4 represents a C 1-4 alkyl group or a C 1-4 dialkylamino group or a C 1-4 alkoxyalkyl group or a C 1-4 dialkylaminoalkyl group or a phenyl or phenyl-C 1-4 alkyl group, R5 represents a hydrogen atom or a C 1-4 alkylcarbonyl group or a C 1-4 alkoxy-carbonyl group, or a pharmaceutically acceptable salt thereof.
