  恶二唑取代的萘并[2,3-b]噻吩-4,9-二酮类化合物是角质形成细胞过度增殖的有效抑制剂。三环醌骨架和恶二唑取代基的构效关系。

  摘要：

  合成了恶二唑取代的萘并[2,3-b]噻吩-4,9-二酮的新型类似物，其中三环醌骨架被较简单的部分系统取代，例如结构较少的环和开链形式，而恶二唑环得以维持。另外，探索了原始的1,2,4-恶二唑环的变体。总的来说，完整的三环醌对于有效抑制人角质形成细胞的过度增殖至关重要，而类似的蒽醌则没有活性。而且，恶二唑环本身不足以引起活性。但是，恶二唑环中杂原子位置的重排导致了高效抑制剂，化合物24b是该系列中最有效的类似物，在纳摩尔范围内显示出IC50。此外，
