effort to understand the structure–activity relationships, we have carried out syntheses of 26 new KRN7000 analogues incorporating aromatic residues in either or both side chains. Structural variations of the phytosphingosine moiety also include varying stereochemistry at C3 and C4, and 4-deoxy and 3,4-dideoxy versions. Their biological activities are described.
KRN7000 是 APC 的 CD1d 蛋白的重要配体,KRN7000/CD1d 复合物可以刺激 NKT 细胞释放多种生物活性细胞因子。为了理解结构-活性关系,我们合成了 26 个新的 KRN7000 类似物,它们在一个或两个侧链中加入了芳香族残基。植物鞘氨醇部分的结构变化还包括 C3 和 C4 以及 4-脱氧和 3,4-双脱氧形式的不同立体化学。描述了它们的生物活性。
