Substituted 4,5-dihydro-6-(substituted)-phenyl-3(2H)-pyridazinones and 6-(substituted) phenyl-3(2H)-pyridazinones

Substituted 4,5-dihydro-6-(substituted)phenyl-3(2H)-pyridazinone compounds and 6-(substituted)phenyl-3(2H)-pyridazinone compounds and pharmaceutically acceptable salts thereof are useful as cardiotonic and antihypertensive agents. Said compounds cause a significant increase in myocardial contractility in the dog. Said compounds also cause a decrease in blood pressure in the spontaneously hypertensive rat. Said compounds are produced by reacting substituted γ-oxobenzenebutanoic acids with suitably substituted hydrazines to provide 4,5-dihydro-6-(substituted)phenyl-3(2H)-pyridazinones which are dehydrogenated to 6-(substituted)phenyl-3(2H)-pyridazinones. Both the intermediate 4,5-dihydro-6-(substituted)phenyl-3(2H)-pyridazinones and the 6-(substituted)phenyl-3(2H)-pyridazinones are useful as cardiotonic and antihypertensive agents.
