  Histone deacetylase 6 (HDAC6) is a peculiar HDAC isoform whose expression and functional alterations have been correlated with a variety of pathologies such as autoimmune disorders, neurodegenerative diseases, and cancer. It is primarily a cytoplasmic protein, and its deacetylase activity is focused mainly on nonhistone substrates such as tubulin, heat shock protein (HSP)90, Foxp3, and cortactin, to

  组蛋白脱乙酰基酶6（HDAC6）是一种特殊的HDAC亚型，其表达和功能改变已与多种病理学相关，例如自身免疫性疾病，神经退行性疾病和癌症。它主要是一种细胞质蛋白，其脱乙酰酶活性主要集中在非组蛋白底物上，例如微管蛋白，热休克蛋白（HSP）90，Foxp3和cortactin等。HDAC6的选择性抑制在健康细胞中不显示细胞毒性作用，通常与I类HDAC同工型的抑制有关。在这里，我们描述了带有五杂环中央核心的新型有效和选择性HDAC6抑制剂的设计和合成。
