(alphaGalCer, KRN7000) has been identified as a modulator of immunological processes through its capacity to bind iNKT cells mediated by CD1d molecules. Some analogues in while the amide group in alphaGalCer is replaced with ester or ether groups were synthesized from d-arabinitol or l-ribose to evaluate their ability to activate iNKT cells. Ester analogues 30a, 31a, and 61 showed activity for IFNgamma
α-半乳糖苷神经酰胺(alphaGalCer,KRN7000)由于具有结合CD1d分子介导的iNKT细胞的能力,已被鉴定为免疫过程的调节剂。从d-阿拉伯糖醇或l-核糖合成了alphaGalCer中的酰胺基被酯或醚基取代时的一些类似物,以评估其激活iNKT细胞的能力。酯类似物30a,31a和61显示出对iNKT细胞产生IFNγ和IL-4的活性,而α-半乳糖基神经酰胺的醚(31b)和4-甲氧基酯(76)类似物对iNKT细胞没有活性。
