reaction pathway. The conformations (5C8 or 8C5) of 1–3 were assigned on the basis of the 1H NMR studies. All compounds were found to be potent inhibitors of various glycosidase enzymes with Ki and IC50 values in the micromolar/nanomolar concentration range and further substantiated by molecular docking studies. The effect of synthesized iminosugars 1–3 on the cytokine secretion of IL-4, IL-6, and IFN-γ
新季吲哚里的亚氨基糖,具有羟甲基在环交界处,即,C-8A-羟甲基-1- deoxycastanospermine同源1A,2A,3A和它们的3-氧代类似物1B,2B,和图3b通过使用分子内还原aminocyclization合成/的内酰胺d甘露糖/ d -葡萄糖衍生的C5-γ叠氮基酯作为关键步骤,其中所述吲哚里骨架的两个环都以一个锅煮以下级联反应路径建立。构象(5 ç 8或8 Ç 5)的1 -在1 H NMR研究的基础上分配了3个。发现所有化合物都是各种糖苷酶的有效抑制剂,其K i和IC 50值在微摩尔/纳摩尔浓度范围内,并通过分子对接研究进一步证实。合成的亚氨基糖的影响1 - 3对IL-4,IL-6和IFN-γ的细胞因子的分泌进行评价。发现所有化合物的T H1偏倚均会增加T H1 / T H2细胞因子比率(IL-6和IL-4)表明它们作为免疫刺激剂的功效。我们的研究表明,吲哚izidin
