its potent and selective profile in preclinical psychopharmacological tests. It blocked CAR in rats with an AB50 of 14 mg/kg po, showed weak affinity for the D2 receptor site (Ki = 104 nM), and showed differential potency in antagonizing apomorphine-induced stereotyped behavior (ED50 = 11 mg/kg ip) and climbing behavior (ED50 = 4 mg/kg ip). Such activities are suggestive of antipsychotic efficacy combined
合成了几种新颖的取代γ-咔啉,并在一系列体外和体内药理试验中进行了研究,以确定潜在的抗精神病活性。大多数化合物在阻断大鼠条件性回避反应(CAR)方面具有口服活性,但没有拮抗阿扑吗啡诱导的刻板印象行为。化合物17(Wy-47,384)是一种具有3-(3-吡啶基)丙基侧链的γ-咔啉,由于其在临床前心理药理学测试中的有效和选择性特征,因此被选作非典型抗精神病药。它在AB50为14 mg / kg po的大鼠中阻断CAR,对D2受体位点的亲和力较弱(Ki = 104 nM),并且在拮抗阿扑吗啡定型行为方面表现出不同的效力(ED50 = 11 mg / kg ip)和攀爬行为(ED50 = 4 mg / kg ip)。
