inflammation-related human diseases. Soybean lipoxygenase-1 is the archetypical example of known lipoxygenases. Here we report the synthesis of linoleic acid and (11,11)-d2-linoleic acid which are combinatorially labeled at the vinylic positions (9, 10, 12, and 13). Combinatorial labeling schemes allow for the simultaneous determination of KIEs in enzymatic reactions using NMR. Substrates are, thus, available
哺乳动物脂氧合酶与多种炎症相关的人类疾病有关。大豆脂氧合酶-1 是已知脂氧合酶的典型例子。在这里,我们报告了亚油酸和 (11,11)-d2-亚油酸的合成,它们在乙烯基位置(9、10、12 和 13)进行了组合标记。组合标记方案允许使用 NMR 同时测定酶促反应中的 KIE。因此,底物可用作脂氧合酶动力学同位素效应 (KIE) 研究中详细机制的探针。
