The synthesis and structure-activity relationships of a number of 1,3-bis(aryloxy)propanes, which are in vivo antagonists of LTD4 in the guinea pig, are described. One of these compounds, 4 (Wy-44,329), was not only approximately equipotent with the standard 1 (FPL 55712) in the LTC4 (ID50 = 0.17 and 0.23 mg/kg iv, respectively) and LTD4 (ID50 = 0.11 and 0.15 mg/kg iv, respectively) challenge models
描述了作为豚鼠LTD4体内拮抗剂的多种1,3-双(芳氧基)丙烷的合成与构效关系。其中一种化合物4(Wy-44,329)不仅与LTC4(ID50分别为0.17和0.23 mg / kg iv)和LTD4(ID50 = 0.11和0.15 mg)中的标准品1(FPL 55712)大致相等。分别为/ kg iv)攻击模型,但在卵清蛋白攻击模型中(ID50分别为0.47 mg / kg和4.1 mg / kg iv)具有更大的效力,并且作用时间更长。该化合物是豚鼠回肠的竞争性LTD4拮抗剂(pA2 = 9.4),具有介质释放(大鼠PCA,ID50 = 0.26 mg / kg iv)和5-脂氧合酶(IC50 = 32 microM vs. 5-HETE)抑制活性。
