A new series of 11-substituted 6,11-dihydrodibenz[b,e]oxepin derivatives was synthesized and evaluated for antiallergic activity. Convenient methods for the preparation of sulfides from alcohols were developed. Structure-activity relationships are described. Compound 7, 11-[2-(dimethylamin)ethyl]thio-6,11-dihydrodibenz[b,e] oxepin-2-carboxylic acid hydrochloride, was the most potent in the rat passive
合成了一系列新的11-取代的6,11-二氢二苯并[b,e] oxepin衍生物,并评估了其抗过敏活性。开发了从醇制备硫化物的简便方法。描述了构效关系。化合物7、11- [2-(二甲基氨基)乙基]硫基-6,11-二氢二苯并[b,e] oxepin-2-羧酸盐酸盐在大鼠被动皮肤过敏反应试验中最有效(ED50 = 0.92 mg /公斤)。它对豚鼠的过敏性支气管狭窄有很强的抑制作用(ED50 = 0.029 mg / kg po),对H1受体的拮抗作用(Ki = 14 nM)几乎没有中枢神经系统的副作用。另外,对前列腺素D2诱导的豚鼠气管分离收缩的拮抗作用(pA2 = 5.73)是新的抗过敏药的一种有吸引力的作用机制。
