Provided herein are bifunctional compounds that bind tau protein and/or promote targeted ubiquitination for the degradation of tau protein. In particular, provided are compounds that can bind tau protein, a protein whose aggregation is implicated in a variety of neurodegenerative disease (e.g., tauopathies), and can promote its degradation by recruiting an E3 ubiquitin ligase (e.g., Cereblon), which can ubiquitinate tau protein, marking it for proteasomal degradation. Also provided are radiolabeled forms of the bifunctional compounds, pharmaceutical compositions comprising the bifunctional compounds, methods of detecting and/or diagnosing neurological disorders, methods of detecting and/or diagnosing pathological aggregation of tau protein (e.g., in the central nervous system), methods of treating and/or preventing neurological disorders, and methods of promoting the degradation of tau protein by E3 ubiquitin ligase activity in a subject by administering a compound or composition described herein.
本文提供了一种双功能化合物,可以结合tau蛋白和/或促进定向泛素化以降解tau蛋白。具体来说,提供了可以结合tau蛋白的化合物,tau蛋白的聚集与多种神经退行性疾病(例如tau病变)有关,并且可以通过招募E3泛素连接酶(例如Cereblon)促进其降解,后者可以泛素化tau蛋白,标记其进行蛋白酶体降解。还提供了双功能化合物的放射标记形式、包含双功能化合物的药物组合物、检测和/或诊断神经疾病的方法、检测和/或诊断tau蛋白的病理性聚集的方法(例如在中枢神经系统中)、治疗和/或预防神经疾病的方法,以及通过给予本文描述的化合物或组合物在受试者中促进E3泛素连接酶活性降解tau蛋白的方法。
