4-[[2-(1H-imidazol-1-yl)-1-[[(4-methoxyphenyl)methoxy]methyl] ethoxy]methyl]benzoic acid (5m) were prepared and evaluated as thromboxane synthase inhibitors. A series of esters of 5m showed a parabolic relationship between lipophilicity and inhibition of TxB2 generation in intact platelets, with activities up to 50 times greater than that of dazoxiben. However, on administration to rabbits the ethyl ester 5d had a
制备了4-[[2-(1H-咪唑-1-基)-1-[[(4-甲氧基苯基)甲氧基]甲基]乙氧基]甲基]苯甲酸的类似物(5m),并作为血栓烷合酶抑制剂进行了评估。一系列5m的酯显示亲脂性与完整血小板中TxB2生成的抑制之间呈抛物线关系,其活性高达达唑西本的50倍。然而,在给药于兔子时,乙酯5d的作用时间很短,这是由于其快速的新陈代谢和通过脱酯作用和β-葡糖醛酸糖化作用的排泄作用。用其他潜在的药效基团取代羧酸酯基团的尝试未成功。
