Abstract: There is disclosed: a compound of formula (I), a method of preparation for this compound and pharmaceutical compositions thereof, wherein: ---- represents a single bond or no bond R0 represents H, hydroxy group, or a linear or branched (C1-C6) alkoxy group; R1 and R2, which are identical or different, each represents: hydrogen, halogen, linear or branched (C1-C6) alkyl group, linear or branched (C1-C6) alkoxy group, hydroxy group, linear or branched (C1-C6) polyhaloalkyl group, nitro group, amino group optionally substituted by one or two linear or branched (C1-C6) alkyl groups, group of formula (II) wherein m represents an integer from 1 to 4, or R1 and R2 form together with the carbon atoms carrying them an aromatic or non-aromatic mono- or bi-cyclic group having from 5-12 ring members and optionally containing 1 or 2 heteroatoms selected from O, S and N; R3 represents H or a group of formula R4 wherein R4 represents: - an aryl group, - a heteroaryl group, - a (C3-C8) cycloalkyl group, - a linear or branched (C1-C6) alkyl group optionally substituted by an aryl group, by a heteroaryl group, by a hydroxy group, by a linear or branched (C1-C6) alkoxy group, or by a group of formula NR5R6 wherein R5 and R6 (which are identical or different) each represents a linear or branched (C1-C6) alkyl group or a linear or branched (C1-C6) hydroxyalkyl group, or R5 and R6 form together with the nitrogen atom carrying them a nitrogen heterocycle,- a group of formula COR7, wherein R7 represents one of the following groups: o aryl, o linear or branched (C1-C6) alkyl (optionally substituted by a group of formula NR8R9 wherein R8 and R9, which are identical or different, each represents a linear or branched (C1-C6) alkyl group or a linear or branched (C1-C6) hydroxyalkyl group, or form together with the nitrogen atom carrying them a nitrogen heterocycle), o amino optionally substituted by one or more groups aryl, heteroaryl or linear or branched (C1-C6) alkyl (optionally substituted by a group of formula NR8R9), o OR10 wherein R10 represents H or an aryl group or linear or branched (C1-C6) alkyl (optionally substituted by a group of formula NR8R9), X represents O or S or a -CH2 - or -CH2-CH2- group; Ar represent an aryl, heteroaryl or aryl-(C1-C6) alkyl group in which alkyl is linear or branched; wherein aryl is phenyl, biphenyl, naphthyl or tetrahydronaphthyl (each of those groups being optionally substituted as defined in the specification), heteroaryl is an aromatic mono- or bi-cyclic group having from 5-12 ring members and containing 1-3 heteroatoms selected from O, S and N (each of these heteroaryl groups being optionally substituted as defined in the specification),  and nitrogen  heterocycle is a saturated monocyclic group having from 5-7 ring members and containing 1-3 heteroatoms selected from O, S, and N, where one of the heteroatoms of the nitrogen heterocycle must be N; their optical isomers, hydrates, solvates and pharmaceutically acceptable addition salts thereof.
