    新型氧杂蒽酮类抗菌剂:半合成、生物学评价和作用机制
    摘要:
    α-Mangostin (α-MG) 已证明对革兰氏阳性细菌显示出有效的活性。然而,α-MG 的酚羟基对抗菌活性的贡献仍然不清楚,严重阻碍了结构修饰的选择以开发更多潜在的基于 α-MG 的抗菌衍生物。在此,设计、合成并评估了 21 种 α-MG 衍生物的抗菌活性。结构活性关系(SARs)显示酚基的贡献顺序为C3>C6>C1,C3处的酚羟基对抗菌活性至关重要。值得注意的是,与母体化合物 α-MG 相比,10a由于其更高的选择性和不溶血,以及在动物皮肤脓肿模型中更有效的抗菌功效,在 C1 处具有一个乙酰基的化合物表现出更高的安全性。我们的证据进一步表明,与 α-MG 相比,10a具有更强的膜电位去极化能力,并导致更多的细菌蛋白泄漏,这与透射电子显微镜 (TEM) 观察到的结果一致。转录组学分析表明,这些观察结果可能与参与膜通透性和完整性生物过程的蛋白质合成受到干扰有关。总的来说,我们的研究结果为开发基于

  • Chemistry of α-mangostin. Studies on the semisynthesis of minor xanthones from <i>Garcinia mangostana</i>

    alpha-Mangostin is the major prenylated xanthone from Garcinia mangostana and it has been used also in recent times as starting material for the semisynthetic preparation of various biologically active derivatives. Its structure is characterised by the presence of few functional groups amenable to chemical manipulations, but present in the molecule in multiple instances (three phenolic hydroxyl groups, two prenyl chains and two unsubstituted aromatic carbons). This study represents a first approach to the systematic investigation of the reactivity of alpha-mangostin and describes the semisynthesis of some minor xanthones isolated from G. mangostana.
  • Cytotoxic and NF-κB Inhibitory Constituents of the Stems of <i>Cratoxylum cochinchinense</i> and Their Semisynthetic Analogues

    A new caged xanthone (1), a new prenylxanthone (2), seven known xanthones, and a known sterol glucoside were isolated from the stems of Cratoxylum cochinchinense, collected in Vietnam. Compounds 1 and 2 were determined structurally by analysis of their spectroscopic data. In addition, five new (10 and 16-19) and eight known prenylated xanthone derivatives were synthesized from the known compounds a-mangostin (3) and cochinchinone A (6). Several of these substances were found to be cytotoxic toward HT-29 human colon cancer cells, with the most potent being 3,6-di-O-acetyl-alpha-mangostin (8, ED50, 1.01 mu M), which was tested further in an in vivo hollow fiber assay, but found to be inactive at the highest dose used (20 mg/kg; ip). Of the substances evaluated in a NF-kappa B p65 inhibition assay, 1,3,7-trihydroxy-2,4-diisoprenylxanthone (5) exhibited the most potent activity (IC50, 2.9 mu M). In a mitochondrial transmembrane potential assay, two new compounds, 1 (IC50, 3.3 mu M) and 10 (IC50, 1.4 mu M), and two known compounds, 3 (alpha-mangostin, IC50, 0.2 mu M) and 11 (3,6-di-O-methyl-alpha-mangostin, IC50, 0.9 mu M), were active. A preliminary analogue development study showed that 3,6-diacetylation and 6-benzoylation both slightly increased the cytotoxicity of a.-mangostin (3), whereas methylation reduced such activity. In contrast, neither acetylation, benzoylation, nor methylation enhanced the cytotoxicity of cochinchinone A (6).

    α-Mangostin (α-MG) has demonstrated to display potent activities against Gram-positive bacterial. However, the contribution of phenolic hydroxyl groups of α-MG to the antibacterial activity remains obscure, severely hampering selection of structure modification to develop more potential α-MG-based anti-bacterial derivatives. Herein, twenty-one α-MG derivatives are designed, synthesized and evaluated
