  公开（公告）日：2018-05-10

  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。
