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 cereblon 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.
本文描述了双功能化合物,其作为B细胞淋巴瘤6蛋白(BCL6;目标蛋白)调节剂而发挥作用。具体而言,本公开的双功能化合物在一端含有结合到各自E3泛素连接酶的小脑球蛋白
配体,而在另一端含有结合到目标蛋白的基团,从而将目标蛋白置于泛素连接酶的近旁,以实现目标蛋白的降解(和抑制)。本公开的双功能化合物表现出与目标蛋白的降解/抑制相关的广泛的药理活性。使用本公开的化合物和组合物治疗或预防由目标蛋白的聚集或积累引起的疾病或障碍。
