in vivo leukotriene biosynthesis inhibitory potency for a group of these hydroxamic acids were investigated. While most of the compounds examined were potent in vitro inhibitors of 5-lipoxygenase, their in vivo potencies varied widely. This discrepancy was usually attributable to differences in bioavailability. Substitution patterns are described that produce potent, orally active inhibitors of leukotriene
异羟肟酸的羰基和氮取代基的性质对这些化合物的生物学特性具有重大影响。与具有相反排列的异羟肟酸相比,具有附加在羰基上的甲基等较小基团和相对较大的氮取代基的异羟肟酸酯通常在体内具有更长的持续时间,产生更高的血浆浓度,并且通常是更有效的体内白三烯生物合成抑制剂。研究了描述这些一组异羟肟酸的体外5-脂氧合酶抑制活性和体内白三烯生物合成抑制能力的构效关系。尽管所检查的大多数化合物是5-脂氧合酶的有效体外抑制剂,但它们的体内效力差异很大。这种差异通常归因于生物利用度的差异。描述了产生有效的,口服活性的白三烯生物合成抑制剂的取代模式。
