With the aim of developing a novel neuroleptic drug, a series of ω-(4-phenyl-1-piperazinyl)-alkoxy-2 (1H)-quinolinone derivatives have been synthesized and tested for anti-methamphetamine and anti-epinephrine activities. Most of the derivatives were found to possess a potent antimethamphetamine activity in the jumping behavior test on mice treated with 3-(3, 4-dihydroxyphenyl)-L-alanine (L-DOPA) and methamphetamine, or in the lethality test with methamphetamine-treated mice. They also showed relatively high anti-epinephrine potency depending on the nature or number of substituents on the phenyl group in the 4-phenyl-1-piperazinyl moiety; some of these compounds induced only weak catalepsy in mice. Among them, 7-3-[4-(2, 3-dimethylphenyl)-1-piperazinyl]propoxy}-2 (1H)-quinolinone (OPC-4392), which was suggested to be a dopamine autoreceptor agonist, was selected for further investigations. The structure-activity relationships are also discussed.
为了开发一种新型的神经安定药物,合成了一系列ω-(4-苯基-1-哌嗪基)-烷氧基-2(1H)-喹啉酮衍生物,并测试了它们的抗甲基苯丙胺和抗肾上腺素活性。大多数衍生物在3-(3, 4-二羟基苯基)-L-天冬氨酸(L-DOPA)和甲基苯丙胺处理的小鼠的跳跃行为测试中显示出强效的抗甲基苯丙胺活性,或者在甲基苯丙胺处理的小鼠的致死性测试中表现出显著效果。它们还表现出相对较高的抗肾上腺素效能,这取决于取代基在4-苯基-1-哌嗪基上的性质或数量;其中一些化合物在小鼠中仅引起轻微的强直症。在这些化合物中,7-3-[4-(2, 3-二甲基苯基)-1-哌嗪基]丙氧基}-2(1H)-喹啉酮(OPC-4392),被认为是一种多巴胺自受体激动剂,已被选定用于进一步研究。同时,本文也讨论了结构-活性关系。
