基于片段的药物发现(FBDD)涉及针对具有临床意义的大分子靶标筛选低分子量化合物。这些化合物是药物开发的起点。在过去的15年里,FBDD已经发展并越来越受欢迎。在本文中,使用X射线晶体学在基于片段的筛选(FBS)背后的原理和技术将被描述,包括片段库设计和使用同步辐射和机器人技术进行高通量X射线数据收集。本文将详细介绍晶体学在FBS中的一些最新应用,包括药物靶点β-分泌酶、苯乙醇胺N-甲基转移酶、磷酸二酯酶4A和Hsp 90的研究。这些例子提供了项目的例子,其中晶体学是简单的或困难的,以及其他筛选方法可以帮助克服衍射质量所必需的晶体学的限制。
Fragment-based drug discovery (FBDD) concerns the screening of low-molecular weight compounds against macromolecular targets of clinical relevance. These compounds act as starting points for the development of drugs. FBDD has evolved and grown in popularity over the past 15 years. In this paper, the rationale and technology behind the use of X-ray crystallography in fragment based screening (FBS) will be described, including fragment library design and use of synchrotron radiation and robotics for high-throughput X-ray data collection. Some recent uses of crystallography in FBS will be described in detail, including interrogation of the drug targets β-secretase, phenylethanolamine N-methyltransferase, phosphodiesterase 4A and Hsp90. These examples provide illustrations of projects where crystallography is straightforward or difficult, and where other screening methods can help overcome the limitations of crystallography necessitated by diffraction quality.
