Abstract

The invention concerns compounds of formula (I), wherein A is a group of formula (a) or (b), wherein: R represents a hydrogen or halogen atom, a —S(O)z(C1–C4)Alk wherein z is 0, 1 or 2, a —NHSO2(C1–C4)Alk, —SO2NH(C1–C4)Alk, —NHSO2—(C1–C4)Alk-phenyl or —NHSO2-phenyl group, said phenyl capable of bearing a halogen atom, a (C1–C4)Alk group or a (C1–C6)alkoxy group; R1 represents a hydrogen atom or a —(C1–C4)Alk, —CO(C1–C4)Alk, —(C1–C4)Alk-phenyl or —CO-phenyl group, said phenyl capable of bearing a halogen atom or a —(C1–C4)Alk or (C1–C6)alkoxy group; R2 is a hydrogen atom, a —SO2(C1–C4)Alk, —SO2—(C1–C4)Alk-phenyl, —SO2-phenyl group, or a —(C1–C4)Alk group; X completes a saturated or unsaturated cycle of 5 to 8 atoms, capable of bearing one or two —(C1–C4)Alk groups and/or two carbonyl groups; R3 and R′3 represent each independently a hydrogen or halogen atom, a —(C1–C6)Alk, hydroxy, —CN, —(C1–C6)alkoxy, —COR4 or Y—CR8R9—COR4 group; Y represents O or CH2; R4 represents a hydroxy, (C1–C6)alkoxy or —NR5R6 group; R5 and R6 independently represent a hydrogen atom, a —(C1–C4)Alk, group, aryl or heteroaryl optionally substituted by a R7 group, aralkyl or heteroaralkyl optionally substituted…
