泛素系统包含许多疾病和病症的大量潜在药物靶标,包括神经退行性疾病、免疫性疾病、代谢性疾病和发育性疾病以及多种癌症。尽管多年的研究,相对较少的临床抑制剂或特异性化学探针的蛋白质内的泛素系统存在,许多有趣的靶蛋白尚未探索。基于片段的药物发现(FBDD)使用共价和非共价方法,通过小文库提供有效和广泛的化学空间覆盖。再加上结构生物学和蛋白质组学的进步,FBDD现在提供了一个全面的筛选平台,在泛素系统中发现抑制剂。在这篇简短的综述中,我们总结了FBDD的当前范围以及它如何应用于泛素激活(E1),泛素缀合(E2),泛素连接酶(E3)和去泛素化(DUB)酶。我们还讨论了FBDD的最新前沿,以及它们如何被应用于抑制剂和新的化学探针的发现,并提供功能的泛素系统的见解。
The ubiquitin system contains a wealth of potential drug targets for many diseases and conditions, including neurodegenerative, immune, metabolic and developmental diseases, as well as multiple cancers. Despite years of research, relatively few clinical inhibitors or specific chemical probes for proteins within the ubiquitin system exist, with many interesting target proteins yet to be explored. Fragment-based drug discovery (FBDD) offers efficient and broad coverage of chemical space with small libraries, using covalent and non-covalent approaches. Coupled with advances in structural biology and proteomics, FBDD now provides a thorough screening platform for inhibitor discovery within the ubiquitin system. In this mini review, we summarise the current scope of FBDD and how it has been applied to ubiquitin-activating (E1), ubiquitin-conjugating (E2), ubiquitin ligase (E3) and deubiquitinating (DUB) enzymes. We also discuss the newest frontiers of FBDD and how they could be applied to enable inhibitor and novel chemical probe discovery and provide functional insight into the ubiquitin system.
