A novel series of heteroarylmethoxyphenylalkoxyiminoalkylcarboxylic acids was studied as leukotriene biosynthesis inhibitors. A hypothesis of structure-activity optimization by insertion of an oxime moiety was investigated using REV-5901 as a starting point. A systematic structure-activity optimization showed that the spatial arrangement and stereochemistry of the oxime insertion unit proved to be
研究了一系列新的杂芳基甲氧基苯基烷氧基亚氨基烷基羧酸作为白三烯生物合成抑制剂。以REV-5901为起点,研究了通过插入肟部分来优化结构活性的假说。系统的结构活性优化表明,肟插入单元的空间排列和立体化学对抑制活性很重要。在大鼠胸膜炎模型中,有希望的前导物S-(E)-11抑制完整人类嗜中性白细胞中LTB(4)的生物合成,IC(50)为8 nM,并且在体内具有优越的口服活性(ED(50)= 0.14 mg / kg)和大鼠过敏反应模型(ED(50)= 0.13 mg / kg)。在肺部炎症模型中,S-(E)-11阻止了LTE(4)的生物合成(ED(50)为0.1 mg / kg)和嗜酸性粒细胞流入(ED(50)为0.2 mg / kg)。
