Many (1-piperazinylcarbonyl)-2(1H)-quinolinone derivatives were synthesized and examined for positive inotropic activity on the canine heart. Among them, 3, 4-dihydro-6-[4-(3-oxo-3-phenylpropyl)-1-piperazinylcarbonyl]-2(1H)-quinolinone (XXIj) and 3, 4-dihydro-6-[4-(oxo-4-phenylbutyl)-1-piperazinylcarbonyl]-2(1H)-quinolinone (XXIl) were found to have potent activity.
合成了多种(1-哌嗪基羰基)-2(1H)-喹啉酮衍生物,并对其在犬心脏上的正性肌力活性进行了检查。其中,3, 4-二氢-6-[4-(3-氧代-3-苯基丙基)-1-哌嗪基羰基]-2(1H)-喹啉酮 (XXIj) 和 3, 4-二氢-6-[4-(氧代-4-苯基丁基)-1-哌嗪基羰基]-2(1H)-喹啉酮 (XXIl) 被发现具有强效活性。
