Compounds with biased cytokine profiles: A selection of α‐GalCer derivatives with modifications in the acyl side chain and/or at the galactose 6′‐position were synthesized and assayed for NKTcellactivation. Gal‐6′‐phenylacetamide‐based derivatives substituted with p‐nitro (32), p‐tert‐butyl (34), or o‐, m‐, or p‐methyl groups (40–42) were found to promote polarization biased towards T helper 1 (TH1)
具有偏倚的细胞因子特征的化合物:合成了一些在酰基侧链和/或半乳糖6'-位置有修饰的α-GalCer衍生物,并分析了NKT细胞的活化。GAL-6'-苯基乙酰胺基与取代的衍生物p -硝基(32),p -叔丁基(34),或ø - ,米-或p -甲基组(40 - 42)被发现促进偏振偏置朝着T辅助1(T H 1)的方向发展。
