important for Hsp90 inhibition. Thus, chimeric analogues of novobiocin and derrubone were constructed and evaluated. These studies confirmed that the functionality present at the 3-position of the isoflavone plays a critical role in determining Hsp90 inhibition and suggests that the bicyclic ring system present in both novobiocin and derrubone do not share similar modes of binding.
天然产物新生霉素和德鲁酮均已证明对 Hsp90 有抑制作用,并且已为每个支架建立了结构-活性关系。鉴于这些化合物具有几个关键的结构特征,我们假设将每种元素的结合可以提供对 Hsp90 抑制重要的结构特征的洞察。因此,构建并评估了新生霉素和德鲁酮的嵌合类似物。这些研究证实异黄酮 3 位存在的功能性在决定 Hsp90 抑制方面起着关键作用,并表明新生霉素和德鲁酮中存在的双环系统不具有相似的结合模式。
