As an important bioactive molecular backbone, drimane meroterpenoids have drawn a great deal of attention from both pharmacologists and chemists. Inspired by the prevalidated success of conformational restriction in the discovery of novel pharmaceutical leads, two distinct tetracyclic drimane meroterpenoids, (−)-pelorol and (+)-aureol, were synthesized from the inexpensive starting material (−)-sclareol
作为一种重要的生物活性分子骨架,杜马烷类萜引起了药理学家和化学家的广泛关注。受构象限制在发现新型药物先导物中预先验证的成功的启发,通过 10 和 8 从廉价的起始材料 (-)-香紫苏醇合成了两种不同的四环二甲基苯萜类化合物 (-)-pelorol 和 (+)-aureol。总产率分别为 5.6% 和 5.4%。温和的条件、操作设施和可扩展性不仅使天然产物本身及其模拟物的合成和生物探索成为可能。首次农化探索表明(−)-pelorol和(+)-aureol对立枯丝核菌具有良好的抗真菌活性,EC 50值分别为7.7和6.9 μM。这表明四环二甲基亚萜类化合物是发现抗真菌先导化合物的有价值的模型。
