identified as a powerful modulator of immunological processes through its capacity to bind CD1d molecules and specifically activate invariant natural killer (NK)-like T cells (iNKT cells). This paper describes the synthesis of 1, the analogous alpha-galactosyl-ceramide 3, and its short chain analogue 'OCH' (2), by use of the 4,6-di-O-tert-butylsilylene (DTBS) protecting group to produce a powerful alpha-galactosylating
α-半乳糖苷神经酰胺(1)通过结合CD1d分子并特异性激活不变的自然杀伤(NK)样T细胞(iNKT细胞),已被认为是免疫过程的有力调节剂。本文通过使用4,6-二-O-叔丁基亚甲硅烷基(DTBS)保护基来描述1,类似的α-半乳糖基神经酰胺3及其短链类似物'OCH'(2)的合成产生强大的α-半乳糖基化剂。体内实验证实这些化合物以CD1d依赖性方式是iNKT细胞的有效和选择性激活剂,每种诱导细胞因子释放的独特过程。这种合成策略将允许产生新的衍生物,用于研究iNKT细胞活化的机制。
