摘要

The present invention relates to compounds of formula (I): (see formula I) in which: .cndot. B1, B2 represent a carbon or nitrogen atom, .cndot. X, Y, X1 and Y1 represent a group chosen from hydrogen, halogen, hydroxy, alkoxy, nitro, cyano, trihaloalkyl and NR a R b in which R a and R b are as defined in the description, .cndot. R1 represents a hydrogen atom or an alkyl group, .cndot. R2 represents a group chosen from hydrogen atom, alkyl, -OR "a, NR'a R'b, -OT a-OR" a, -NR "a-T a-NR'a R'b, NR" aC (O) -T a H, -OC (O) -T a H, -OT a-NR a'R b ', -NR "a-T a-OR" a-NR "a-T a-CO2R "a, -NR" aC (O) -T a-NR'a R'b in which R'a, R'b, R "a and T a are as defined in the description, .cndot. R3, R4 represent a hydrogen atom or an alkyl group, .cndot. A represents a group of formula -CH (R5) -CH (R6) -, -CH = C (R7) -, -C (R7) = CH-, -C (O) -CH (R8) -, -CH (R8) -C (O) - in which R5, R6, R7 and R8 are as defined in the description, their isomers defined in the description, N-oxides, as well as their addition salts with an acid or a pharmaceutically acceptable base. The invention also relates to pharmaceutical compositions containing the compounds of formula (I).
