    先前已证明,分枝杆菌的磷脂酰肌醇甘露糖苷(PIM)提取物可抑制小鼠的过敏性气道炎症。为了帮助确定活性的结构要求,合成了PIM1(2)(1),PIM1(6)(2)和PIM2(3),并测试了它们在变应性哮喘小鼠模型中抑制细胞炎症的能力。合成的PIM在哮喘模型中均能有效抑制气道嗜酸性粒细胞增多,其中PIM1(6)最有效。观察到所监测的所有炎性细胞的抑制,表明细胞炎的普遍阻断。非甘露糖基化磷脂酰肌醇(PI)没有抑制作用,表明至少一个α-d-甘露聚糖基对活性是必需的。

Here, we report the efficient synthesis of all PIMs including phosphatidylinositol (PI) and phosphatidylinositol mono- to hexa-mannoside (PIM1 to PIM6). Robust synthetic protocols were developed for utilizing bicyclic and tricyclic orthoesters as well as mannosyl phosphates

The optical resolution of racemic 3,4,5,6-tetra-O-benzyl-myo-inositol to enantiomers was accomplished via diastereomeric menthoxyacetic esters. Iodonium ion-promoted glycosylation has been used for the preparation of chiral mannosyl-myo-inositol. Bis(diisoprop

    reports that the NPOE and (NPGAC) donors frequently react at only one of the two hydroxy groups in good yield, whereas the corresponding benzylated donor (NPGALK) is less discriminating, and frequently gives lower yields. In a key experiment to examine the basis of the selectivity, it was found that the highly hindered C3 OH of 4,6-O-benzylidene methyl a-D-altropyranoside was selectively glycosylated
    Angyal 实验室 1965 年发表的一篇文章报道说,四苄基肌醇的顺式邻位二醇基团与赤道 OH 处的酰化剂发生区域选择性反应,有时仅与酰化剂反应,但与轴向 OH 处的烷化剂反应。Fraser-Reid 及其同事最近的报告表明,对于四-O-苄基肌醇的反式-1,3-二醇以及二-O-丙基甘露喃糖苷的 C2-C4 羟基也发现了这种选择性. 此外,后者的工作人员报告说区域选择性可以扩展到糖苷化反应。因此,正戊烯基原酸 (NPOE) 和 2-O-酰基正戊烯基糖苷 (NPGAC) 供体在赤道 OH 处优先反应(如果不是排他性的),而 2-O-烷基对应物 (NPGALK) 则产生混合物,通常主要糖苷化发生在轴向 OH。本手稿检查了几种邻二醇,并报告说 NPOE 和 (NPGAC) 供体经常仅在两个羟基中的一个上反应,产率很高,而相应的苄基化供体 (NPGALK) 区分度较低,并且经常给出较低的产

    (R)-Tuberculostearic acid (2) was synthesized in seven steps from (S)-citronellol (5). The carbon chain of 2 was assembled by copper-catalyzed cross coupling of (S)-citronellol tosylate (6) and hexylmagnesium bromide; subsequent ozonolysis and reaction with 6-benzyloxyhexylmagnesium bromide furnished alcohol 10. Functional group manipulation afforded (R)-2 in 49% overall yield from 5. DCC coupling of (R)-2 with 3-O-benzyl-1-O-palmitoyl-sn-glycerol (16), followed by hydrogenolytic removal of the benzyl group and treatment with benzyl bis(diisopropyl)phosphoramidite, afforded phosphoramidite 20. Tetrazole-mediated coupling of 20 with PIM1 head group 21 gave 22, and subsequent debenzylation afforded phosphatidylinositol mono-mannoside, PIM1 (23). Similarly, coupling of 20 and 24 and removal of the benzyl protecting groups gave PIM2 (1c). Both 23 and 1c have a clearly defined acylation pattern, which was confirmed by mass spectrometry, with sn-1 palmitoyl and sn-2 tuberculostearoyl groups on the glycerol moiety. Both 23 and 1c were shown to modulate the release of the pro-inflammatory cytokine, IL-12, in a dendritic cell assay.
