Synthesis of unnatural analogues, that contain (S)-3-hydroxytetradecanoyl moieties in place of the corresponding natural (R)-isomers, of both lipid A and its biosynthetic precursor, designated precursor Ia or lipid IVA, has been achieved through our recently developed procedure. (S)-3-Hydroxytetradecanoic acid was prepared from its racemate through the optical resolution by the use of a lipase and
合成非天然类似物,含有 (S)-3-羟基十四烷酰基部分代替相应的天然 (R)-异构体,脂质 A 及其生物合成前体,指定前体 Ia 或脂质 IVA,已通过我们最近开发的程序。(S)-3-羟基十四烷酸是通过使用脂肪酶和随后的分级重结晶通过光学拆分从其外消旋体制备的。脂质 A 的 (S)-酰基类似物表现出比相应的天然脂质 A 稍强的白细胞介素 6 诱导活性,生物合成前体的 (S)-酰基类似物在抑制白细胞介素 6 诱导方面的活性远高于天然前体。白细胞介素-6 脂多糖。
