在过去的二十年中,基于片段的先导发现(FBLD)已被证明对各种靶标,甚至是具有挑战性的蛋白质-蛋白质相互作用(PPI)系统都是富有成效的。核磁共振(NMR)光谱起着至关重要的作用,从最初的基于片段的筛选到铅的产生,因为它能够探测目标和低分子量片段之间固有的弱相互作用。在这里,我们回顾了NMR FBLD过程从最初的图书馆建设,导致一代。我们描述了有关片段库设计,配体和蛋白质观察筛选,蛋白质-配体结构模型生成的技术方面。对于弱粘合剂,初始命中到铅的演变可以引导从NMR光谱检索的结构信息,包括化学位移扰动,转移pseudocontact位移,和顺磁弛豫增强。这一观点探讨了从弱片段筛选命中到具有挑战性的PPI靶点的有效线索的结构引导优化。
Fragment-based lead discovery (FBLD) has proven fruitful during the past two decades for a variety of targets, even challenging protein–protein interaction (PPI) systems. Nuclear magnetic resonance (NMR) spectroscopy plays a vital role, from initial fragment-based screening to lead generation, because of its power to probe the intrinsically weak interactions between targets and low-molecular-weight fragments. Here, we review the NMR FBLD process from initial library construction to lead generation. We describe technical aspects regarding fragment library design, ligand- and protein-observed screening, and protein–ligand structure model generation. For weak binders, the initial hit-to-lead evolution can be guided by structural information retrieved from NMR spectroscopy, including chemical shift perturbation, transferred pseudocontact shifts, and paramagnetic relaxation enhancement. This perspective examines structure-guided optimization from weak fragment screening hits to potent leads for challenging PPI targets.
