  The description relates to MDM2 binding compounds, including bifunctional compounds comprising the same, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins which are degraded and/or otherwise inhibited by bifunctional compounds according to the present invention. In particular, the description provides compounds, which contain on one end a ligand which binds to the MDM2 E3 ubiquitin ligase and on the other end a moiety which binds a target protein such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of that protein. Compounds can be synthesized that exhibit a broad range of pharmacological activities consistent with the degradation/inhibition of targeted polypeptides of nearly any type.

  描述涉及MDM2结合化合物，包括包含相同结构的双功能化合物，这些化合物可作为靶向泛素化的调节剂，特别是根据本发明抑制各种多肽和其他蛋白质的化合物。具体而言，描述提供了一种化合物，其一端含有结合到MDM2 E3泛素连接酶的配体，另一端含有结合到靶蛋白的基团，使得靶蛋白与泛素连接酶靠近，以促使该蛋白的降解（和抑制）。可以合成出一系列具有广泛药理活性的化合物，与几乎任何类型的靶向多肽的降解/抑制一致。
