  摘要：

  在这项工作中，我们描述了有效的和选择性的基于喹诺酮的组蛋白脱乙酰基酶6（HDAC6）抑制剂的合成。喹诺酮部分已被用作抑制HDAC6的创新生物活性帽基。其合成是通过多组分反应实现的。通过采用计算研究对这些产物的效能和选择性进行了优化，从而发现了二乙基氨基甲基衍生物7g和7k是最有希望的命中分子。在细胞研究中对这些化合物进行了研究，以评估其对结肠癌（HCT-116）和组织细胞性淋巴瘤（U9347）癌细胞的抗癌作用，显示出良好至极好的效能，并通过凋亡诱导导致肿瘤细胞死亡。小分子7a，7g和7k能够强烈抑制细胞质HDAC酶，略微抑制核HDAC酶，分别增加微管蛋白和组蛋白3的赖氨酸9和14的乙酰化。化合物7g还能够增加HCT-116细胞中的Hsp90乙酰化水平，从而进一步支持其HDAC6抑制特性。这些分子的细胞毒性和致突变性检测显示出安全的特性；此外，化合物7k的HPLC分析显示出良好的溶解性和稳定性。
