  The present disclosure relates to bifunctional compounds, which find utility as modulators of tau protein. In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a VHL or cereblon ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds tau protein, such that tau protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of tau. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of tau protein. Diseases or disorders that result from aggregation or accumulation of tau protein are treated or prevented with compounds and compositions of the present disclosure.

  本公开涉及双功能化合物，其作为tau蛋白的调节剂具有实用性。具体而言，本公开涉及含有一端结合到E3泛素连接酶的VHL或cereblon配体，另一端结合到tau蛋白的双功能化合物，使得tau蛋白与泛素连接酶靠近，以实现tau蛋白的降解（和抑制）。本公开展示了与tau蛋白降解/抑制相关的广泛药理活性。本公开的化合物和组合物用于治疗或预防由tau蛋白聚集或积累导致的疾病或紊乱。

  The description relates to cereblon E3 ligase binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present disclosure. In particular, the description provides compounds, which contain on one end a ligand which binds to the cereblon E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

  该描述涉及cereblon E3连接酶结合化合物，包括包含相同成分的双功能化合物，这些化合物作为靶向泛素化的调节剂具有实用价值，尤其是抑制剂，可降解和/或以其他方式抑制根据本公开的双功能化合物。特别是，该描述提供了化合物，其一端含有与cereblon E3泛素连接酶结合的配体，另一端含有与目标蛋白结合的部分，使目标蛋白位于泛素连接酶附近以降解（和抑制）该蛋白。可以合成表现出广泛药理活性的化合物，与几乎所有类型的靶向多肽的降解/抑制一致。
