5-lipoxygenase activating protein (FLAP) based on MK-0591. Emphasis was made on modifications to the nature of the link between the indole and the quinoline moieties, to the substitution pattern around the two heterocycles and to possible replacements of the quinoline moiety. Lead optimization culminated in (3-[1-(4-chlorobenzyl)-3-(t-butylthio)-5-(pyridin-2-ylmethoxy)-ind ol-2-yl]-2,2-dimethylpropanoic
本文报道了基于MK-0591的5-脂氧合酶激活蛋白(FLAP)抑制剂的SAR研究。强调了对吲哚和喹啉部分之间的连接性质的修饰,两个杂环周围的取代方式以及喹啉部分的可能取代。铅优化最终达到(3- [1-(4-氯苄基)-3-(叔丁硫基)-5-(吡啶-2-基甲氧基)-吲哚-2-基] -2,2-二甲基丙酸(18k ),作为有效吸收的白三烯的有效抑制剂,在功能模型中具有良好的吸收性和活性。
