Many 5- (3-amino-2-hydroxypropoxy) -3, 4-dihydro-8-hydroxy-2 (1H) -quinolinone derivatives were synthesized and examined for positive inotropic activity on the canine heart. These compounds were prepared by the reaction of 8-alkoxy-5- (2, 3-epoxypropoxy) -2 (1H) -quinolinone derivatives and various amines. Among them, 3, 4-dihydro-8-hydroxy-5-[3- (1, 1, 3, 3-tetramethylbutylamino) propoxy] -2 (1H) -quinolinone hydrochloride (IIIf) was found to have potent positive inotropic activity with a relatively minor increase in heart rate.
研究人员合成了许多 5-(3-氨基-2-羟基丙氧基)-3,4-二氢-8-羟基-2 (1H) -喹啉酮衍生物,并考察了它们对犬心脏的正性肌力活性。这些化合物由 8-烷氧基-5-(2,3-环氧丙氧基)-2 (1H) -喹啉酮衍生物和各种胺反应制备而成。其中,3, 4-二氢-8-羟基-5-[3-(1, 1, 3, 3-四甲基丁氨基)丙氧基] -2 (1H) -喹啉酮盐酸盐(IIIf)具有强效的正性肌力活性,心率增加相对较小。
