  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 Pd-catalyzed Suzuki coupling reactions of a series of aryl chlorides and aryl bromides containing basic nitrogen centers with arylboronic acids in water in the absence of added base are reported. The reactions proceed either partially or entirely under acidic conditions. After surveying twenty-two phosphorus ligands, high yields of products were obtained with aryl chlorides only when a bulky ligand

  据报道，在不添加碱的情况下，水中一系列含碱性氮中心的芳基氯化物和芳基溴化物与水中的芳基硼酸进行钯催化的Suzuki偶联反应。反应在酸性条件下部分或全部进行。在调查了二十二个磷配体后，只有在庞大的配体2-（二叔丁基-膦基）-1-苯基-1 H上，芳基氯化物才能获得高收率的产品。使用了吡咯（cataCXium®PtB）。相反，在不存在添加的碱和添加的配体的情况下，芳基溴化物产生高产率的产物。为了完全探索酸性条件下的Suzuki偶联过程，使用几种模型底物在缓冲的酸性介质中进行了一系列反应。在cataCXium®PtB的存在下，4-氯苄基胺在缓冲的pH 6.0下产生了高收率的产品；在缓冲pH 5.0和更低的条件下，产量急剧下降。产量的下降归因于Pd-配体络合物的分解，这是由于在较酸性的水性介质中配体的质子化所致。相反，在没有添加配体的情况下，4-氨基-2-氯吡啶在缓冲的pH 3.5和4下产生定量产率
