apomorphine-induced emesis in dogs, apomorphine-induced stereotypy in rats, and amphetamine-induced circling in lesioned rats. This lack of nonselective, dopamine-receptor blocking effects makes 2e attrative as a potential neuroleptic.
描述了1'-[3-(4-氟苯甲酰基)丙基] -3-苯基螺[异苯并呋喃-1(3H),4'-哌啶](2a)和八个卤素和甲氧基类似物的合成。在大鼠的Sidman规避范式中,该化合物一般比口服氯丙嗪更有效,而比haloperido更低。1'-[3-(4-氟苯甲酰基)丙基] -3-(4-氟苯基)螺[异苯并呋喃-1(3H),4'-哌啶](2e)在此测试中达到氟哌啶醇的渗透压,表现出在抑制猴回避方面也很活跃。化合物2e在拮抗狗中由阿扑吗啡引起的呕吐,大鼠中由阿扑吗啡引起的刻板症以及在患病大鼠中由苯丙胺引起的盘旋中的活性比氟哌啶醇低得多。缺乏非选择性的多巴胺受体阻断作用使2e成为潜在的精神抑制药。
