    (-)-Macrolactin A、(+)-Macrolactin E 和 (-)-Macrolactinic Acid 的全合成:Stille 交叉偶联化学练习
    摘要:
    强效抗病毒剂 (-)-macrolactin A (1) 和两个相关的家族成员 (+)-macrolactin E (5) 和 (-)-macrolactinic acid (7) 的全合成已经实现,利用统一的、收敛和高度立体控制的策略。广泛使用钯催化的 Stille 交叉偶联反应来构建三种分离的二烯(包括大环化),这是成功策略的基石。这些天然产物的全合成不再通过发酵获得,证实了它们的相对和绝对立体化学,并为进一步的生物学研究提供了可能的类似物。

    Total Synthesis of Macrolactin A with Versatile Catalytic, Enantioselective Dienolate Aldol Addition Reactions
    摘要:
    A highly convergent total synthesis of macrolactin A (1) utilizes modern asymmetric catalytic C-C coupling methods. The longest linear sequence in the route is 16 steps with an average yield of 86% per step. This total synthesis is valuable, because 1, which has been shown to possess activity against HIV, is not readily accessible from its natural source, a taxonomically unclassified deep-sea bacterium.

  • Stereocontrolled Synthesis of (−)-Macrolactin A

    The total synthesis of (-)-macrolactin A, a 24-membered macrolide, has been achieved using a newly developed 1,3-diol synthon for the introduction of two key stereogenic centers. The synthon was derived from sequential use of the Noyori asymmetric reduction followed by chiral sulfoxide methodology. Tellurium-derived cuprate organometallics offered an efficient and highly stereoselective means for installation

    BmmI could specifically attach C3-C5 alkyl acid thioesters onto 7-OH of MLN A, and also exhibits substrate promiscuity towards acyl acceptors with different scaffolds. Crystal structure of BmmI covalently linked with succinyl group and systematic mutagenesis highlighted the role of an oxyanion hole-like geometry in the recognition of carboxyl-terminated acyl donors. Engineering of this geometry expanded
    Macrolactins (MLNs) 是一类重要的抗黄斑变性和抗肿瘤药物。丙二酰化/琥珀酰化 MLNs 更重要,因为它们具有克服多重耐药细菌的功效。然而,催化这种反应的酶仍然是个谜。在此,我们破译了负责此步骤的 β-内酰胺酶同源物 BmmI。BmmI 可以特异性地将 C3-C5 烷基酸硫酯连接到 MLN A 的 7-OH 上,并且还表现出对具有不同支架的酰基受体的底物混杂性。BmmI 与琥珀酰基共价连接的晶体结构和系统诱变突出了氧阴离子孔状几何形状在识别羧基端酰基供体中的作用。这种几何结构的工程扩大了其底物范围,R166A/G/Q 变体可识别多达 C12 烷基酸硫酯。BmmI 与酰基受体 MLN A 的结构揭示了 Arg292 在识别大环内酯底物方面的重要性。此外,建立了 BmmI 催化的酰基转移反应的机制,揭示了 Lys76 在控制酰基供体和催化方面的灵巧作用。我们的研究揭示了酰基转移

    The present invention relates to an anti-inflammatory use of macrolactin compounds such as macrolactin A, 7-O-malonyl macrolactin A and 7-O-succinyl macrolactin A, which are produced from a novel Bacillus strain of Bacillus polyfermenticus KJS-2 (KCCM10769P). The macrolactin compounds provided by the present invention were confirmed to greatly suppress the expression and formation of inducible nitric oxide synthetase (iNOS) and cyclooxygenase-2 (COX-2) which are proteins related to the formation of inflammatory mediators, and to accordingly inhibit the formation of nitric oxide (NO) and of prostaglandin E2 (PGE2) which are the metabolites of the proteins. In addition, the macrolactin compounds provided by the present invention were confirmed to have excellent effects in inhibiting the formation of tumor necrosis factor-alpha (TNF-α), interleukin-1β (IL-1β), interleukin-6 (IL-6) and granulocyte macrophage colony-stimulating factor (GM-CSF), which are pro-inflammatory cytokines. Therefore, the macrolactin compounds produced by the Bacillus polyfermenticus KJS-2 strain according to the present invention can provide excellent anti-inflammatory agents.
