    A simple method of transforming clalssical tricyclic antihistaminics into nonsedative antiallergic agents with equal potency in rats and guinea-pigs is described. A series of [4-(5H-dibenzo[a, d]cyclohepten-5-ylidene)-piperidino]alkanoic acid derivatives (6a) and related compounds (6b-f) were synthesized and examined for antiallergic and antihistaminic activities and effects on the central nervous system (CNS) in comparison with the corresponding N-methyl derivatives (2a-f). N-Alkylcarboxylic acids (6a-f) showed stronger inhibitory effects on 48h homologous passive cutaneous anaphylaxis (PCA) in rats than 2a-f, and also were less effective in prolongation of the sleeping time on hexobarbital-induced anesthesia in mice in comparison with 2a-f. As a result of further modification, it was found that introduction of an oxygen atom into the central ring of the tricyclic system in amphoteric compounds enhanced their antiallergic and antihistaminic activities. 3-[4-(6H-Dibenz[b, e]oxepin-11-ylidene)piperidino]propionic acid (6c) exhibited strong inhibitory effects on 48h homologous PCA in rats (ED50=0.067mg/kg, p.o.) and on histamine-induced bronchoconstriction in anesthetized guinea-pigs (ED50=0.0085mg/kg, p.o.), and thus is a promising candidate as an antiallergic agent.
    描述了一种将经典三环抗组胺药物转化为具有相同效力的无镇静抗过敏剂的简单方法,适用于大鼠和豚鼠。合成了一系列[4-(5H-二苯并[a, d]环庚烯-5-亚基)-哌啶基]烷酸衍生物(6a)及相关化合物(6b-f),并与相应的N-甲基衍生物(2a-f)比较了其抗过敏和抗组胺活性以及对中枢神经系统(CNS)的影响。N-烷基羧酸(6a-f)在大鼠48小时同源被动皮肤过敏反应(PCA)中的抑制作用强于2a-f,并且在小鼠六氟巴比妥诱导麻醉的睡眠时间延长方面效果不如2a-f。进一步修饰的结果发现,在两性化合物的三环系统中心环中引入氧原子增强了它们的抗过敏和抗组胺活性。3-[4-(6H-二苯并[b, e]氧烯-11-亚基)哌啶基]丙酸(6c)在大鼠48小时同源PCA中表现出强的抑制作用(ED50=0.067mg/kg,口服),以及在麻醉豚鼠中对组胺诱导的支气管收缩的抑制作用(ED50=0.0085mg/kg,口服),因此是一个有前景的抗过敏剂候选物。
