| abstract |
The invention concerns compounds of formula (I) wherein: the pair (A, B) represents (N, N), (N, C) or (C, N); n = 0 if A represents a nitrogen atom, if not, n = 1; m = 0 if B represents a nitrogen atom, if not m = 1; R1 and R2 independently of each other, represent a hydrogen atom, a C1-C6 alkyl, a C2-C6 alkenyl, or a cyclo C3-C6 alkyl group; Ar1 represents a phenyl radical or a pyridyl radical substituted by the groups R3, R'3 and R''3; Ar2 represents a phenyl radical substituted by the groups R4 and R' 4', wherein R3, R'3, R''3, R4 and R'4, independently of one another, represent a hydrogen atom, a halogen atom, a C1-C4 alkyl, hydroxy, a C1-C4 alkoxy, a cyano, a nitro, a perfluoro C1-C2 alkyl, an amino, a C1-C4 alkylamino, a di-(C1-C4 alkyl)-amino, a C1-C4 alkoxycarbonyl amino, a (C1-C4 alkoxycarbonyl) (C1-C4 alkyl)-amino, aminosulphonyl, a C1-C4 alkyl-aminosulphonyl or a di(C1-C4 alkyl)-aminosulphonyl group; and their salts, N-oxides and hydrates. Said compounds have therapeutic applications. |
