A series of novel benzoheterocyclic [(methoxyphenyl)amino]oxoalkanoic acid esters has been prepared. These compounds were tested as inhibitors of rat polymorphonuclear leukocyte 5-lipoxgenase (LO) in vitro and as inhibitors of leukotriene D4 (LTD4) and ovalbumin (OA) induced bronchospasm in the guinea pig (GP) in vivo. In general, inhibitory activity against 5-LO, LTD4, and OA was broadest for ben
已经制备了一系列新颖的苯并杂环[(甲氧基苯基)氨基]氧代链烷酸酯。这些化合物在体外试验中作为大鼠多形核白细胞5-脂氧合酶(LO)的抑制剂,以及白三烯D4(LTD4)和卵清蛋白(OA)诱导的豚鼠(GP)支气管痉挛的抑制剂。通常,对于含苯并噻唑的类似物(对苯并噻唑大于苯并咪唑比对苯并恶唑,苯并呋喃要大得多)对5-LO,LTD4和OA的抑制活性最广。最有效的5-LO抑制剂4-[[[3-(2-苯并噻唑基甲氧基)-苯基]羟基氨基] -4-氧代丁酸甲酯(7)的IC50为0.36 microM。但是,化合物7与OA相比没有活性。体内最有效的化合物4-[[[3-[(1-甲基-2-苯并咪唑基)甲氧基]苯基]-氨基] -4-氧代丁酸甲酯4,在十二指肠内以50 mg / kg的浓度分别抑制LTD4-和OA诱导的支气管痉挛分别达到83%和60%。在Ames分析中使用五种细菌菌株(TA1535,TA1537,TA1
