  report the synthesis of a series of new sorbicillinoid analogues and assessed their anti-inflammatory activities. Our results reveal that side chain substitution with (E)-2-butenoyl, (E)-3-(4-fluorophenyl)-2-propenoyl, and (E)-3-(3,4,5-trimethoxyphenyl)-2-propenoyl significantly enhanced the inhibitory effects of the derivatives on nitric oxide (NO) production and inducible NO synthesis (iNOS) expression

  最近，我们展示了从海洋真菌中分离出的山梨醇类化合物的潜在抗炎作用。在这里，我们报告了一系列新的山梨霉素类似物的合成，并评估了它们的抗炎活性。我们的结果表明侧链被 (E)-2-丁烯酰基、(E)-3-(4-氟苯基)-2-丙烯酰基和 (E)-3-(3,4,5-三甲氧基苯基)-2 取代-丙烯酰基显着增强了衍生物对小鼠巨噬细胞中脂多糖 (LPS) 刺激的一氧化氮 (NO) 产生和诱导型 NO 合成 (iNOS) 表达的抑制作用。进一步的化学衍生表明，单甲基间苯二酚骨架在抑制 LPS 诱导的培养细胞炎症反应方面比二甲基间苯二酚骨架效果更好。在 29 种合成的山梨霉素类似物中，化合物图4b和12b表现出最强的抗炎活性，有望开发成可作为有效抗炎剂探索的先导化合物。

  作者：Kelly A. Volp、Diane M. Johnson、Andrew M. Harned

  DOI：10.1021/ol201211f

  日期：2011.9.2

  A concise (12 step) total synthesis of sorbicillactone A and 9-epi-sorbicillactone A is reported. Unlike typical routes to the sorbicillinoids, this strategy does not start from sorbicillin and allows for the production of the bicyclic core on a multigram scale. The intramolecular conjugate addition of a tethered malonate serves as an effective means of introducing the lactone ring and provides a synthetic
