  烟内酯类似物抗 TMV 的合成及构效关系研究

  摘要：

  最初提出的 (±)-烟内酯 A 结构的合成是一种具有三个连续手性中心的强效抗病毒木脂素，从丙烯酸甲酯开始分 5 步合成。合成的关键步骤包括 In 催化的区域选择性烯丙基化和 Mn 催化的 Mukaiyama 水合反应。我们的合成策略还使我们能够获得其他三种差向异构体并研究构效关系。合成化合物的核磁共振数据与分离样品的核磁共振数据不匹配，表明烟内酯 A 的结构仍有待重新分配。评估了所有合成目标化合物的抗烟草花叶病毒 (anti-TMV) 活性。生物测定结果表明，(±)-8-去甲基烟内酯 A 显示出与市售药物宁南霉素相似的抗 TMV 活性，

  New antifungal scaffold derived from a natural pharmacophore: Synthesis of α-methylene-γ-butyrolactone derivatives and their antifungal activity against Colletotrichum lagenarium

  摘要：

  Thirty new and thirty-four known analogues were designed and synthesized to improve the potential use of the alpha-methylene-gamma-butyrolactone ring, a natural pharmacophore. All structures were confirmed by H-1 and C-13 NMR, MS, and single-crystal X-ray diffraction analyses. The results of antifungal and cytotoxic activity indicated that the synthesized analogues showed significant inhibitory activity and limited selectivity. Compound 45 exhibited the highest antifungal activity with IC50 = 22.8 mu M but moderate cytotoxic activity with IC50 = 28.5 mu M (against BGC823 cell line) and 7.7 mu M (against HeLa cell line). Analysis of structure-activity relationships revealed that the incorporation of an aromatic ring into the beta, gamma positions of the lactone ring improved antifungal activity, and that the introduction of electron-withdrawing groups into the aromatic rings increased the activity compared with electron-donating groups. The above results identified 4-phenyl-3-phenyl-2-methylenebutyrolactone (33) as a lead scaffold for discovering and developing novel and improved crop-protection agents. (C) 2013 Elsevier Ltd.

  Design, synthesis, and evaluation of α-methylene-γ-butyrolactone analogues and their evaluation as anticancer agents is described. SAR identified a spirocyclic analogue 19 that inhibited TNFα-induced NF-κB activity, cancer cell growth and tumor growth in an ovarian cancer model. A second iteration of synthesis and screening identified 29 which inhibited cancer cell growth with low-μM potency. Our data

  The zinc/silver-graphite mediated Dreiding-Schmidt reactions between aldehydes and the 2-bromomethyl-acrylate derived sultamamides (+)/(-)-28 or (+)/(-)-30 gave the corresponding substituted alpha-methylene-gamma-butyrolactones with ee's up to 90%. Enantiomerically pure compounds were obtained by semipreparative HPLC using a chiral stationary phase. (C) 1997 Elsevier Science Ltd.
