Some pyridazinone and phthalazinone derivatives and their vasodilator activities
Özet
In this study, 6-[(4-arylidene-2-phenyl-5-oxoimidazolin-1-yl)phenyl]-4,5- dihydro-3(2H)-pyridazinone and 4-[(4-arylidene-2-phenyl-5-oxoimidazolin-1-yl) phenyl]-1(2H)-phthalazinone derivatives were synthesized by reacting 6-(4-aminophenyl)-4,5-dihydro-3(2H)-pyridazinone or 4-(4-aminophenyl)-1(2H)- phthalazinone compound with different 4-arylidene-2-phenyl-5(4H)-oxazolone derivatives. The vasodilator activities of the compounds were examined both in vitro and in vivo. Some pyridazinone derivatives showed appreciable activity.
