2, 4-Diamino-[E]-6-[2-(3-pyridyl)ethenyl]1, 3, 5-triazine (3a), leukotriene C4 (LTC4) antagonist, was found to possess a protective effect of HCl·ethanol-induced gastric lesions. Analogues of 3a were synthesized and evaluated for the effect as well as antagonistic activity against LTC4-induced contraction. Seven compounds (3a-d, f-h) exhibited a potent protective effect on gastric lesions which was considered to be based on the antagonistic activity against LTC4. The structure-activity relationships of the derivatives (3a-k) are discussed.
2, 4-二氨基-[E]-6-[2-(3-吡啶基)乙烯基]1, 3, 5-三嗪(3a)是白三烯C4(LTC4)拮抗剂,被发现对盐酸乙醇引起的胃损伤具有保护作用。研究人员合成了3a的类似物,并评估了其对LTC4引起的收缩的作用和拮抗活性。七种化合物(3a-d,f-h)对胃损伤表现出有效的保护作用,这被认为是基于对LTC4的拮抗活性。讨论了衍生物(3a-k)的结构-活性关系。
