Both the S and R enantiomers of (E)-13-hydroxy-10-oxo-11-octadecenoic acid (1) and (E)-10-oxo-11-octadecen-13-olide (2) had similar IC50 values against P388 mouse leukemia cells; i.e. the stereochemistry of the asymmetric center of 1 and 2 had no influence on the cytotoxic activity. Bioassay results of various compounds related to 1 and 2 suggests that the 10-oxo and lactone moieties of 2 were important for enhancing the cytotoxicity.
(E)-13-羟基-10-氧代-11-十八烯酸(1)和(E)-10-氧代-11-十八烯-13-内酯(2)的 S 和 R 对映体对 P388 小鼠白血病细胞的 IC50 值相似,即 1 和 2 的不对称中心的立体化学结构对细胞毒性活性没有影响。与 1 和 2 有关的各种化合物的生物测定结果表明,2 的 10-氧代和内酯分子对增强细胞毒性非常重要。
