(p-Amylcinnamoyl)anthranilic acid (3a) had moderate antagonist activities against LTD4-induced smooth muscle contraction on guinea pig ileum and LTC4-induced bronchoconstriction in anesthetized guinea pigs. Modifications were made in the hydrophobic part (cinnamoyl moiety) and the hydrophilic part (anthranilate moiety) of 3a. A series of 8-(benzoylamino)-2-tetrazol-5-yl-1,4-benzodioxans and 8-(ben
(p-戊基肉桂酰基)邻氨基苯甲酸(3a)对LTD4-诱导的豚鼠回肠平滑肌收缩和LTC4诱导的豚鼠支气管收缩具有中等程度的拮抗活性。对3a的疏水部分(肉桂酰基部分)和亲水部分(邻氨基苯甲酸酯部分)进行了修饰。揭示了一系列的8-(苯甲酰基氨基)-2-四唑-5-基-1,4-苯并二恶烷和8-(苯甲酰基氨基)-2-四唑-5-基-4-氧代-4H-1-苯并吡喃。白三烯C4和D4的有效拮抗剂。在这两个系列中,ONO-RS-347(18k)和ONO-RS-411(19h)分别是最有效和口服活性的拮抗剂。讨论了构效关系。
