  摘要：

  4,5-二氢-6-(取代基)苯基-3(2H)-吡啶并酮化合物和6-(取代基)苯基-3(2H)-吡啶并酮化合物及其药用盐可作为强心和降压药物。这些化合物在狗体内可显著增加心肌收缩力。这些化合物还可导致自发性高血压大鼠的血压降低。这些化合物是通过将取代的γ-氧基苯丁酸与适当取代的肼反应制备的，从而提供4,5-二氢-6-(取代基)苯基-3(2H)-吡啶并酮，然后将其脱氢为6-(取代基)苯基-3(2H)-吡啶并酮。中间体4,5-二氢-6-(取代基)苯基-3(2H)-吡啶并酮和6-(取代基)苯基-3(2H)-吡啶并酮均可作为强心和降压药物。

  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 y-oxobenzene-butanoic 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 4,5-dihydro-6-(substituted)-phenyl-3(2H)-pyridazinones and the 6-(substituted)-phenyl-3(2H)-pyridazinones are useful as cardiotonic and antihypertensive agents. The compounds have the formula: where represents a double or single bond and A is anyone of five types of heterocyclic ring-containing radicals, and R2, R3 and Y are hydrogen or various substituents.
