  Is NMR Fragment Screening Fine-Tuned to Assess Druggability of Protein–Protein Interactions?

  摘要：

  Modulation of protein-protein interactions (PPIs) with small molecules has been hampered by a lack of lucid methods capable of reliably identifying high-quality hits. In fragment screening, the low ligand efficiencies associated with PPI target sites pose significant challenges to fragment binding detection. Here, we investigate the requirements for ligand-based NMR techniques to detect rule-of-three compliant fragments that form part of known high affinity inhibitors of the PPI between the von Hippel-Lindau protein and the alpha subunit of hypoxia-inducible factor 1 (pVHL:HIF-1 alpha). Careful triaging allowed rescuing weak but specific binding of fragments that would otherwise escape detection at this PPI. Further structural information provided by saturation transfer difference (STD) group epitope mapping, protein-based NMR, competitive isothermal titration calorimetry (ITC), and X-ray crystallography confirmed the binding mode of the rescued fragments. Our findings have important implications for PPI druggability assessment by fragment screening as they reveal an accessible threshold for fragment detection and validation.

  Compounds & Methods for the Enhanced Degradation of Targeted Proteins & Other Polypeptides by an E3 Ubiquitin Ligase

  摘要：

  本发明涉及双功能化合物，其作为靶向泛素化的调节剂具有实用性，特别是作为本发明的双功能化合物对各种被降解和/或受到抑制的多肽和其他蛋白质的抑制剂。具体而言，本发明涉及含有一端结合泛素连接酶的VHL配体，另一端结合靶蛋白的基团的化合物，使得靶蛋白靠近泛素连接酶以促使该蛋白的降解（和抑制）。本发明展示了与本发明化合物相关的广泛的药理活性范围，与靶向多肽的降解/抑制一致。

  The present invention relates to bifunctional compounds, which find utility as modulators of targeted ubiquitination, especially inhibitors of a variety of polypeptides and other proteins that are degraded and/or otherwise inhibited by bifunctional compounds of the present invention. In particular, the present invention is directed to compounds, which contain on one end a VHL ligand that binds to the ubiquitin ligase and on the other end a moiety that 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. The present invention exhibits a broad range of pharmacological activities associated with compounds of the present invention, consistent with the degradation/inhibition of targeted polypeptides.
