benzyloxyalkyl-substituted 1,2,3-triazolyl α-GalCer analogues are reported. The novel α-GalCer analogues activate invariant natural killer T (iNKT) cells via CD1d mediated presentation, which was confirmed by in vitro tests performed on iNKT hybridomas incubated with CD1d proteins. When tested on isolated murine splenocytes, the T1204B and T1206B compounds stimulated higher levels of both IFN-γ and IL-4 cytokine
已知用1,2,3-三唑连接基取代α-GalCer结构中的酰胺部分会引起偏向Th2免疫的反应,并且在其酰基或植物鞘氨醇结构末端含有糖环的糖脂会表现出增强的Th1免疫反应。在当前的研究中,报道了苄氧基烷基取代的1,2,3-三唑基α-GalCer类似物的聚焦文库的合成和免疫学筛选。新颖的α-神经酰胺类似物激活不变的自然杀伤T(我NKT)通过介导的CD1d介绍,这证实了细胞体外试验上执行我与CD1d蛋白孵育的NKT杂交瘤。在离体鼠脾细胞上进行测试时,与α-GalCer相比,T1204B和T1206B化合物在体外刺激了更高水平的IFN-γ和IL-4细胞因子表达。
