Compounds of the formula
and pharmaceutically acceptable salts thereof, in which A is -N = N-NH-, -X-C(R2) = N-. -N = C(R2)-X-, -X-CH(R2)-C(R2) = N- or -N=C(R2)-CH(R2)-X-,wherein X is sulphur, oxygen or a nitrogen moiety (preferably NH) and R2 is hydrogen, amino, substituted amino, C1-6alkyl, substituted acylamino or one of the following groups:
wherein Ra is hydrogen, amino substituted amino, Ci-6alkoxy,a heterocyclic five membered ring or -NHCOR', wherein R' is C1-6alkyl, aryl or heterocyclic five membered ring, Rb is hydrogen. C1-6alkoxy, C1-5alkylthio or hydroxy, Rc is hydrogen, C1-6alkyl or oxygen, Rd is C1-6alkyl or oxygen, Re is hydrogen. hydroxy or C1-5alkoxy, and Rf is C1-6alkyl with the proviso that when two R2 groups are present in the A group, at least one of them is hydrogen, B is -(CH2)m-C(R3R4)-(CH2)n-, -C(R3)=CH-, -CH=C(R3)-, -O-[C-(R3R4)]n-, -[C(R3R4)n-O-. -S-[C(R3R4)]n or -[C(R3R4)]n-S-, wherein R3 and R4, which can be independently the same or different, are hydrogen, C1-6alkyl, aryl (preferably phenyl) or pyridyl and m and n are independently zero or 1; D is either oxygen or sulphur; the two R-groups are independently hydrogen, C1-6alkoxy. C1-6a[kyl, amino, acylamino, substituted acylamino, nitro, halogen, cyano, -CHO, carboxy, carbamoyl; R1 is hydrogen or C.-salkyl or R and R: together form a fused 6-membered heterocyclic ring. Said compounds are effective in the treatment of congestive heart failure.
