Bifunctional compounds, which find utility as modulators of B-cell lymphoma 6 protein (BCL6; target protein), are described herein. In particular, the bifunctional compounds of the present disclosure contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand that 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 bifunctional compounds of the present disclosure exhibit 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.
本发明描述了双功能化合物,其作为B细胞淋巴瘤6蛋白(BCL6;靶蛋白)的调节剂。特别是,本发明中的双功能化合物一端含有与相应的E3泛素连接酶结合的Von Hippel-Lindau、cereblon、凋亡蛋白抑制剂或小鼠双分钟同源蛋白2的配体,另一端含有与靶蛋白结合的部分,使得靶蛋白被置于泛素连接酶附近,以促进靶蛋白的降解(和抑制)。本发明中的双功能化合物展示了与靶蛋白降解/抑制相关的广泛药理活性。可以通过本发明中的化合物和组合物治疗或预防由靶蛋白聚集或积累引起的疾病或失调。
