  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。

  The present disclosure relates to bifunctional compounds, which find utility as modulators of estrogen receptor (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a cereblon, Von Hippel-Lindau ligase-binding moiety, Inhibitors of Apotosis Proteins, or mouse double-minute homolog 2 ligand, which binds to the respective E3 ubiquitin ligase, and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.
