Syntheses were conducted of novel benzimidazole derivatives that suppress histamine release from mast cells, inhibit 5-lipoxygenase, and possess antioxidative action. Among the compounds synthesized, 1-[2-[2-(4-hydroxy- 2,3,5-trimethylphenoxy)ethoxy]ethyl]-2-(4-methyl-1- homopiperazino)benzimidazole (22) potently suppressed histamine release from rat peritoneal mast cells triggered by the antigen-antibody
合成了新的苯并咪唑衍生物,这些衍生物可抑制组胺从肥大细胞中释放,抑制5-脂氧合酶并具有抗氧化作用。在合成的化合物中,1- [2- [2-(4-羟基-2,3,5-三甲基苯氧基)乙氧基]乙基] -2-(4-甲基-1-高哌嗪基)苯并咪唑(22)有效抑制组胺的释放抗原抗体反应触发大鼠腹膜肥大细胞中的表达,抑制大鼠嗜碱性白血病1(RBL-1)细胞中的5-脂氧合酶,并阻止Fe(3 +)-ADP诱导大鼠肝中NADPH依赖性脂质过氧化微粒体,除了拮抗组胺引起的豚鼠回肠的收缩。
