基于片段的药物发现方法越来越受欢迎,因为它们提供的药物先导物比传统的高通量筛选具有更高的配体效率。然而,现有的片段检测方法并没有解决基于片段的配体发现的核心问题:如何通过二级片段最佳地延伸一级配体?动态筛选方法通过使用蛋白质靶标作为配体组装的模板来解决这个问题,从而从低亲和力片段产生高亲和力结合物。这篇综述总结了动态筛选方法的最新工作,该方法导致了针对各种靶标的几种高亲和力结合物的开发。讨论了已发表方法的优点和局限性,并强调了动态筛选方法对药物发现过程的可能贡献。
Fragment-based methods for drug discovery are increasingly popular because they provide drug leads with greater ligand efficiency than conventional high-throughput screening. However, established methods for fragment detection do not address the central question in fragment-based ligand discovery: how can a primary ligand be optimally extended by a secondary fragment? Dynamic screening methods solve this issue by using a protein target as a template for ligand assembly, thus yielding high-affinity binders from low-affinity fragments. This review summarizes recent work on dynamic screening methodology, which resulted in the development of several high-affinity binders for various targets. Strengths and limitations of the published approaches are discussed and possible contributions of dynamic screening methodology to the drug discovery process are highlighted.
