configuration of optically active compounds was unequivocally established by X‐ray crystallographic analysis and comparative chiral HPLC‐UV profile. All compounds of the series were tested for formyl peptide receptor (FPR) agonist activity, and four were found to be active, with EC50 values in the micromolar range.

本文描述了 C5-甲基哒嗪系列的三种外消旋体和相应的非手性类似物的合成,以及纯对映异构体的分离及其绝对构型分配。为了获得旋光化合物,研究了使用四种手性固定相(CSP:Lux Amylose-2、Lux Cellulose-1、Lux Cellulose-2 和 Lux Cellulose-3)的 HPLC-UV 直接色谱分离方法。使用直链淀粉三(5-氯-2-甲基苯基氨基甲酸酯) (Lux Amylose-2) 实现了最佳分辨率,在半制备规模上分离了单个对映异构体,对映异构体过量,适用于生物测定。通过 X 射线晶体学分析和比较手性 HPLC-UV 图谱明确确定了旋光化合物的绝对构型。微摩尔范围内的50 个值。手性 25:400–408,2013 年。© 2013 威利期刊公司。
