methamphetamine lethality in rats than 1, while it was as weak in inhibitory activity of apomorphine-induced stereotype in rats (ED50 greater than 500 mg/kg, p.o.) as 1. On the other hand, N-[(1-ethyl-2-pyrrolidinyl)methyl]-2-methyl-5-methylthio-2, 3-dihydrobenzofuran-7-carboxamide (30) showed a classical neuroleptic profile with a potency comparable to haloperidol in antagonistic activity on apomorphine-induced
合成了一系列具有稳定分子内氢键的2,3-二氢苯并呋喃-7-羧酰胺,并在药理学模型中评估了其抗精神病活性。其中,N-[((1-丁基-2-吡咯烷基)甲基] -2-甲基-5-氨磺酰基-2,3-二氢苯并呋喃-7-羧酰胺(15)显示出与sulpiride(1 )和比1更高的亲脂性。化合物15对阿扑吗啡诱导的小鼠过度活动(ED50 = 30 mg / kg,口服)的拮抗活性比对甲基苯丙胺致死力的增强作用强11倍,而对15如阿斯吗啡对大鼠的刻板印象抑制作用弱(ED50大于500 mg / kg,口服)为1。另一方面,N-[(1-乙基-2-吡咯烷基)甲基] -2-甲基- 5-甲硫基-2,3-二氢苯并呋喃-7-羧酰胺(30)在对阿扑吗啡诱导的小鼠过度活动的拮抗活性方面表现出与氟哌啶醇相当的经典抗精神病药(ED50 = 0.65 mg / kg,口服)。还讨论了结构-活性关系。
