Synthesis of several 1,5-Anhydro-d-fructose (1,5-AF) derivatives to evaluate inhibitory activities of the inflammasome was carried out. Recently, 1,5-AF reported to suppress the inflammasome, although with only low activity. We focused on the hydration of 2-keto form of 1,5-AF and speculated that this hydration was the cause of low activity. Therefore, we synthesized some 1,5-AF derivatives that would not be able to form the dimer conformation and can be expected to have high activity against inflammasome, and then evaluated their inhibitory activities with respect to the NLRP3 inflammasome by using mouse bone marrow-derived macrophages and human THP-1 cells. As a result, some synthesized 2-keto form compounds had much higher inhibitory activities with respect to the NLRP3 inflammasome than did 1,5-AF.

几个1,5-脱水-的合成d -fructose（1,5- AF）衍生物的炎性进行评价抑制活性。近来，据报道1，5-AF抑制炎症小体，尽管活性低。我们着眼于2-酮形式的1,5-AF的水合，并推测这种水合是低活性的原因。因此，我们合成了一些1,5-AF衍生物，这些衍生物将无法形成二聚体构象，并且有望对炎症小体具有较高的活性，然后通过使用小鼠骨髓-核糖核酸评估它们对NLRP3炎症小体的抑制活性。衍生的巨噬细胞和人类THP-1细胞。结果，某些合成的2-酮形式的化合物对NLRP3炎性小体的抑制活性比1,5-AF高得多。
