摘要
核磁共振波谱通过检测组成有机化合物分子的原子核跃迁而得到反映核性质的参数以及周围化学环境对这些参数的影响规律.这些参数的相关内容包含了极其详尽的有机化合物分子结构和分子间相互作用的信息,并构成了核磁共振结构解析和生物靶分子-配体相互作用研究的理论基础.在生物医药研发领域内,科研院所和公司企业的研发工作者们一直在努力探索利用核磁共振波谱监测生物靶分子-配体相互作用作为药物发现工具的潜能.本文旨在针对核磁共振波谱在药物发现过程中活性化合物筛选的最新研究进展进行综述.
Nuclear magnetic resonance （NMR） spectroscopy is often valued for its ability to shed light on molecular structure, but its greatest potential in drug discovery probably lies in the information it can reveal about molecular interactions at atomic level. The NMR parameters of the atoms in a compound, such as chemical shift, diffusion coeffi- cient and relaxation time, are highly sensitive to the chemical environment surrounding them. Measuring these parameters therefore can provide information on whether a small molecule binds to a target protein or nucleic acid, and what are the interacting parts of the small molecule and the macromolecular target. The NMR approaches can be used to validate ligand binding and/or to identify potential ligands in the mixtures of compounds. In the last decade, the ability of NMR spectroscopy as a tool to monitor intermolecular interactions in drug discovery has been increasingly appreciated in both acade mia and industry. In this perspective, we highlight some major applications of NMR in drug discovery in this review article, with focus on hit screening.
