A series of novel [[(naphthalenylmethoxy)- and [[(quinolinylmethoxy)phenyl]amino]oxoalkanoic acid esters have been prepared. These compounds were tested as inhibitors of rat polymorphonuclear leukocyte (PMN) 5-lipoxygenase (LO) in vitro and as inhibitors of ovalbumin (OA) and leukotriene D4 (LTD4) induced bronchospasm in the guinea pig (GP) in vivo. Many naphthalenyl compounds were potent inhibitors
已经制备了一系列新型的[[((萘基甲氧基)-和[[(喹啉基甲氧基)苯基]氨基]氧代链烷酸酯。在体外测试了这些化合物作为大鼠多形核白细胞(PMN)5-脂氧合酶(LO)的抑制剂以及卵白蛋白(OA)和白三烯D4(LTD4)诱导的豚鼠(GP)支气管痉挛的抑制剂。GP中许多萘化合物是5-LO的有效抑制剂,而一些喹啉基化合物是LTD4介导的支气管痉挛的有效抑制剂。最有效的萘化合物4-[[[3-(2-萘甲氧基甲氧基)苯基]羟基氨基] -4-氧代丁酸甲酯(6v)在5-LO分析中的IC50为0.6 microM。体内最有效的化合物4-[[[3-(2-喹啉基甲氧基)苯基]羟基氨基] -4-氧代丁酸甲酯(6e)的ED50为3.3 mg / kg,为27。分别针对LTD4-和OA引起的支气管痉挛分别为4 mg / kg(十二指肠内)。当作为LTD4诱导的分离GP气管螺旋带收缩的拮抗剂进行测试时,显示6e是竞争性抑制剂,pKB值为5
