are constituents of the mycobacterial cell wall and possess immunomodulatory activities. Certain PIM derivatives have immunoprotective activity and are of interest as anti‐inflammatory agents. In order to identify simplified analogues of PIMs that retain this interesting activity, we have prepared a series of new analogues based either on an acyclic or on a heterocyclic scaffold that replaces the inositol
磷脂酰肌肌醇甘露糖苷(PIM)是分枝杆菌细胞壁的组成部分,具有免疫调节活性。某些PIM衍生物具有免疫保护活性,并作为抗炎药受到关注。为了鉴定保留这种有趣活性的PIM的简化类似物,我们基于无环或杂环骨架替代了肌醇部分,制备了一系列新的类似物,并评估了这些化合物对LPS诱导释放的抑制作用巨噬细胞对一氧化氮和促炎细胞因子的影响 发现肌醇部分可以被氮杂-环醇(三羟基-哌啶)或草酸-环醇(三羟基-四氢吡喃)单元有利地取代,并且携带OH的碳的构型没有显着作用。
