Some pyrrole substituted aryl pyridazinone and phthalazinone derivatives and their antihypertensive activities
Özet
In this work, some 2-nonsubstituted/2-methyl-/2-(2-acetyloxyethyl)-6-[4- (substituted pyrrol-1-yl)phenyl]-4,5-dihydro-3(2H)-pyridazinone, derivatives and 2-nonsubstituted/2-methyl- 4-[4-(substituted pyrrol-1-yl)phenyl]-1(2H)- phthalazinone derivatives were synthesised by reacting hexan-2,5-dion or 1-aryl-3-carbethoxypent-1,4-diones with corresponding 2-substituted/ nonsubstituted 6-(4'-aminophenyl)-4,5-dihydro-3(2H)-pyridazinone or 2-substituted/nonsubstituted-4-(4'-aminophenyl)-(2H)-phthalazinone under Paal-Knorr pyrrole synthesis conditions. The antihypertensive activities of the compounds were examined both in vitro and in vivo. Some pyridazinone derivatives showed appreciable activity
