A series of furo[3,2-b]indole carboxylic acids, tetrazoles, and carbamoyltetrazoles was prepared and tested in vitro with use of a model of active pulmonary anaphylaxis, the modified Schultz-Dale Test (SDT). In this model, isolated guinea pig lung strips are repeatedly challenged with antigen in the presence of an antihistamine (H1). Most of the acidic furo[3,2-b]indoles tested inhibited the leukotriene-mediated
制备了一系列呋喃[3,2-b]吲哚羧酸,四唑和氨基甲酰基四唑,并使用活性肺过敏模型(改良的舒尔茨-戴尔试验(SDT))进行了体外试验。在此模型中,在抗组胺药(H1)的存在下,用抗原反复攻击分离的豚鼠肺带。测试的大多数酸性呋喃[3,2-b]吲哚以剂量相关的方式抑制白三烯介导的肺收缩。与N-甲基类似物(IC50大于或等于22.0 microM)相比,具有N-苯基取代基的化合物对SDT的抑制作用更强(IC50小于或等于5.0 microM)。大多数N-苯基类似物在SDT中比Fisons的介质释放抑制剂procrocromil(FPL-57,787; IC50 = 6.3 microM)更有效。最有力的愤怒[3,2-b]吲哚是在C-7处未被取代且被N-苯基,2-氨基甲酰基四唑和3-烷氧基取代基取代的那些。在10-30 microM的浓度下,所有测试的羧酸酯类似物均较弱或无活性。
