Steroidal bivalent ligands for the estrogen receptor: Design, synthesis, characterization and binding affinities
摘要:
Steroidal bivalent ligands for the estrogen receptor (ER) were designed using crystal structures of ER alpha dimers as a template. The syntheses of several 17 alpha-ethynylestradiol-based bivalent ligands with varying linker compositions and lengths are described. The binding affinities of these bivalent ligands for ERa and ER beta were determined. In the two series of bivalent ligands that we synthesized, there is a clear correlation between linker length and binding affinity, both of which reach a maximum at the same tether length. Further studies are underway to explore aspects of bivalent ligand and control compound binding to the ERs and their effects on ER dimer formation; these results will be reported in a subsequent publication.

The present disclosure relates to bifunctional compounds, which find utility as modulators of c-Met and/or p38 (target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hippel-Lindau, cereblon, Inhibitors of Apotosis Proteins or mouse double-minute homolog 2 ligand which 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 present disclosure exhibits 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.
