It is important to find more effective and safer immunosuppressants, because clinically used immunosuppressive agents have significant side effects. A series of N‐substituted iminosugar derivatives were designed and synthesized, and their immunosuppressive effects were evaluated by the CCK‐8 assay. The results revealed that iminosugars 10 e and 10 i, that is, (3R,4S)‐1‐(4‐heptyloxylphenylethyl)pyrrolidine‐3
重要的是找到更有效,更安全的免疫抑制剂,因为临床上使用的免疫抑制剂具有明显的副作用。设计并合成了一系列N取代的亚氨基糖衍生物,并通过CCK-8分析法评估了它们的免疫抑制作用。结果显示亚氨基糖10 e和10 i,即(3 R,4 S)-1-(4-庚氧基氧基苯基乙基)吡咯烷-3,4-二醇和(3 R,4 S)-1- [2- (2-氯-4-(p -tolylthio) -苯基-1-基)乙基]吡咯烷-3,4-二醇,分别表现出对小鼠脾细胞增殖的最强的抑制作用(IC 50 = 2.16和2.48μ米分别),而在亲水头附近(化合物10 j – n)含有酰胺基的亚氨基糖则没有抑制作用。进一步的研究表明,对脾细胞增殖的抑制作用可能来自抑制IFN-γ和IL-4细胞因子。我们的结果表明合成的亚氨基糖,特别是化合物10e中和10 I,保持电位免疫抑制剂。
