α-GalCer analogues featuring a phytoceramide 3- and 4-amino group have been synthesized. A Mitsunobu reaction involving phthalimide was employed for the introduction of the amino groups at the 3- and 4-positions of suitable phytosphingosine-derived precursors. The influence of these modifications on the interaction with the T-cell receptor of NKT cells was investigated, as well as the capacity of the
已经合成了具有植物神经酰胺 3- 和 4- 氨基的 α-GalCer 类似物。使用涉及邻苯二甲酰亚胺的 Mitsunobu 反应在合适的植物鞘氨醇衍生前体的 3 位和 4 位引入氨基。研究了这些修饰对与 NKT 细胞的 T 细胞受体相互作用的影响,以及氨基修饰的类似物在体内给药后诱导细胞因子反应的能力。
