straightforward method for the simultaneous preparation of (2S,3R,2′R)- and (2S,3R,2′S)-2′-hydroxy-ceramides (2′-OHCer) from (2S,3R)-sphingosine acetonide precursors and racemic mixtures of 2-hydroxy fatty acids (2-OHFAs) is described. The obtained 2′-OH-C4-, -C6-, -C12-, -C16-Cer and 2′-OH-C6-dhCer pairs of diastereoisomers were characterized thoroughly by TLC, MS, NMR, and optical rotation. Dynamic and multidimensional
用于同时制备的简单方法(2小号,3 - [R,2' - [R )-和(2小号,3 - [R,2'小号)-2'-羟基神经酰胺从(2'- OHCer)(2小号, 3 - [R)-鞘氨醇丙酮前体和 2-羟基脂肪酸 (2-OHFA) 的外消旋混合物进行了描述。获得的 2'-OH-C4-、-C6-、-C12-、-C16-Cer 和 2'-OH-C6-dhCer 对非对映异构体通过 TLC、MS、NMR 和旋光度进行了彻底表征。动态和多维 NMR 研究提供的证据表明,2'-OHCers 的极性界面比在相应的非羟基化类似物中观察到的更扩展和更刚性。对于 (2' R )- 和 (2' S )-2'-OH-C6-Cers 及其二氢类似物,观察到 MCF7 细胞生长抑制的立体特异性特征。(2' R )-异构体比 (2' S )-异构体更具活性(IC 50 ∼3 μM/8 μM 和 IC 50分别为 ∼8 μM/12
