The present disclosure relates to bifunctional compounds that serve as degraders (and/or inhibitors) of the estrogen receptor (target protein). In the present disclosure, the bifunctional compounds, which contain a target protein (estrogen receptor) binding moiety and a E3 ubiquitin ligase (CRBN) binding moiety, are directed to bind to both estrogen receptor and CRBN, such that the ER is placed in close proximity to the E3 ligase to mediate ubiquitylation of the target protein followed by degradation of the target protein by the proteasome. The present disclosure provides methods for synthesizing the herein disclosed bifunctional compounds, and their pharmacological activities associated with degradation or inhibition of the target protein. Further, the present disclosure teaches the utilization of such compounds in a treatment for proliferative diseases, including cancer, particularly breast cancer, and especially ER+ breast cancer.
本公开涉及具有双重功能的化合物,可作为雌激素受体(靶蛋白)的降解物(和/或抑制剂)。在本公开中,所述的双功能化合物包含一个靶蛋白(雌激素受体)结合基团和一个E3泛素连接酶(CRBN)结合基团,被指导结合到雌激素受体和CRBN上,使得ER与E3连接酶靠近,从而介导靶蛋白的泛素化,然后通过蛋白酶体降解靶蛋白。本公开提供了合成此处所述的双功能化合物的方法,以及与靶蛋白的降解或抑制相关的药理活性。此外,本公开还教导了在增殖性疾病(包括癌症,特别是ER+乳腺癌)的治疗中利用这些化合物的方法。
