  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.

  使用小分子靶向 von Hippel-Lindau E3 泛素连接酶以破坏 VHL/HIF-1α 相互作用

  摘要：

  E3 泛素连接酶结合蛋白质靶标，导致其泛素化和随后的降解，由于其出色的底物特异性，是有吸引力的药物靶标。然而，小分子抑制剂的开发已证明极具挑战性，因为调节 E3 连接酶活性需要靶向蛋白质-蛋白质相互作用。通过合理的设计，我们生成了第一个靶向 von Hippel-Lindau 蛋白 (VHL) 的小分子，VHL 是 E3 连接酶的底物识别亚基，也是癌症、慢性贫血和缺血的重要靶点。我们还获得了与我们最有效的抑制剂结合的 VHL 的晶体结构，证实该化合物模拟了转录因子 HIF-1α（VHL 的底物）的结合模式。

  E3 ubiquitin ligases are attractive targets in the ubiquitin–proteasome system, however, the development of small-molecule ligands has been rewarded with limited success. The von Hippel–Lindau protein (pVHL) is the substrate recognition subunit of the VHL E3 ligase that targets HIF-1α for degradation. We recently reported inhibitors of the pVHL:HIF-1α interaction, however they exhibited moderate potency

  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.
