Our previous reports have highlighted the first-generation leukotriene B4 (LTB4) receptor antagonist SC-41930 (7-[3-(4-acetyl-3-methoxy-2-propylphenoxy)propoxy]3,4- dihydro-8-propyl-2H-1-benzopyran-2-carboxylic acid) which has potent oral, topical, and intracolonic activity in various animal models of inflammation. Extensive structure-activity relationship studies, in which a series of heterocyclic
我们以前的报道强调了第一代白三烯B4(LTB4)受体拮抗剂SC-41930(7- [3-(4-乙酰-3-甲氧基-2-丙基苯氧基)丙氧基] 3,4-二氢-8-丙基- 2H-1-苯并吡喃-2-羧酸)在各种动物炎症模型中具有有效的口服,局部和结肠内活性。广泛的结构-活性关系研究,其中探索了SC-41930的甲基酮官能团的一系列杂环取代,确定了SC-50605(7- [3- [2-(2-环丙基甲基)-3-甲氧基-4- (4-噻唑基)苯氧基]丙氧基] -3,4-二氢-8-丙基-2H-1-苯并吡喃-2-羧酸)作为一系列噻唑的优化类似物。发现SC-50605在LTB4受体结合,趋化性和脱粒试验中比SC-41930显着更有效。通过口服,局部,静脉内和结肠内给药途径,它在结肠炎和表皮炎症的动物模型中也显示出非常好的活性。通过手性色谱法获得了SC-50605的拆分对映异构体,它们均显示出良好的体外和体内活性。
