  • Computer Modelling and Synthesis of Deoxy and Monohydroxy Analogues of a Ribitylaminouracil Bacterial Metabolite that Potently Activates Human T Cells

    5-(2-Oxopropylideneamino)-6-d-ribitylaminouracil (5-OP-RU) is a natural product formed during bacterial synthesis of vitamin B2. It potently activates mucosal associated invariant T (MAIT) cells and has immunomodulatory, inflammatory, and anticancer properties. This highly polar and unstable compound forms a remarkably stable Schiff base with a lysine residue in major histocompatibility complex class I-related
    5-(2-氧代丙基亚基)-6-d-核糖基尿嘧啶(5-OP-RU)是在细菌合成维生素B2的过程中形成的天然产物。它有效激活粘膜相关的不变T(MAIT)细胞,并具有免疫调节,炎症和抗癌特性。这种高度极性和不稳定的化合物在抗原呈递细胞中表达的主要组织相容性复合物I类相关蛋白(MR1)中与赖酸残基形成非常稳定的席夫碱。受5-OP-RU的核糖基部分与MAIT细胞上的MR1和T细胞受体(TCR)结合的重要性启发,在计算机上去除了每个OH。DFT计算和MD模拟显示,C3'-OH与尿嘧啶N1H之间存在非常稳定的氢键,这极大地限制了每个核糖基-OH的柔韧性和位置,可能会影响它们与MR1和TCR的交互。通过使用脱氧策略和动力学控制的亚胺形成,合成了4-OP-RU的四个单脱氧核糖基和四个单羟基烷基类似物,作为探测T细胞活化机制的新工具。

    We report the first total synthesis of trachycladines A (10 steps, 34.2% overall yield) and B (11 steps, 35.0% overall yield) by using 5-deoxy-1,2,3-tri-O-acetyl-β-D-ribofuranose as the starting material. The critical step was the SnCl4 assisted regio- and steroselective deprotection of perbenzylated 1-O-methyl-5-deoxyribofuranose. The enzyme adenylate deaminase (EC 3.5.4.6) was successfully applied to the chemoenzymatic synthesis of trachycladines B.

  • Synthesis and Cytokine Modulation Properties of Pyrrolo[2,3-<i>d</i>]-4-pyrimidone Nucleosides
    作者:Guangyi Wang、Robert C. Tam、Esmir Gunic、Jinfa Du、Josie Bard、Bharati Pai
    DOI:10.1021/jm000035+
    日期:2000.6.1
    A series of pyrrolo[2,3-d]pyrimidone nucleosides were synthesized and evaluated for their ability to enhance Type 2 cytokines and to suppress Type 1 cytokines in human T cells activated in vitro. Compounds 16b, 16c, 16d, 18c, and 19b induced substantial enhancement of IL-4 (a Type 2 cytokine) levels while three compounds (16b, 16c, and 16f) showed significant suppression of IFN gamma (a Type 1 cytokine) levels. The results revealed a strict structural requirement for the nucleoside-mediated enhancement of IL-4. Modifications of the ribofuranose moiety of the nucleosides either abolished or dramatically reduced the activity. Both the 5'-hydroxy and 5-carboxamidine are crucial for the activity. Of the few nucleoside analogues that demonstrated enhancement on Type 2 cytokine production, 7-(beta-D-ribofuranosyl)pyrrolo[2,3-d]-4-pyrimidone-5-carboxamidine (16c) showed a dramatic enhancement (>200%) of IL-4 levels and a significant enhancement (36%) of IL-5 levels. Moreover, this compound showed substantial suppression of the Type 1 cytokines, IFN gamma (42%), IL-2 (54%), and TNF alpha (55%). Similarly, compound 16b showed a substantial enhancement of IL-4 (46%) and suppression of IL-2 (35%), IFN gamma (30%), and TNF alpha (26%). To our knowledge, these are the first nucleoside analogues that induce a Type 2 cytokine bias in T cells. The cytokine modulation property of 16c and 16b merits the therapeutic evaluation of these compounds in treating diseases in which immunopathology is associated with polarized Type 1 cytokine responses.
