  potential involvement in oncogenic pathways as well as possible roles in both metabolic and immune disorders in addition to viral infections. Potent, novel, and selective inhibitors of USP7 have been developed using both rational and structure-guided design enabled by high-resolution cocrystallography. Initial hits were identified via fragment-based screening, scaffold-hopping, and hybridization exercises

  泛素特异性蛋白酶7（USP7，HAUSP）由于在调节Mdm2水平（进而调节p53）中的作用，已成为药物发现中的引人注目的靶标。由于USP7可能参与致癌途径以及除病毒感染外在代谢和免疫疾病中的可能作用，因此人们对USP7的兴趣也越来越高。USP7的强效，新型和选择性抑制剂已通过高分辨率共结晶技术的合理设计和结构指导设计得到开发。最初的命中是通过基于片段的筛选，支架跳跃和杂交练习来确定的。描述了两个不同的子系列以及相关的结构-活性关系趋势，以及旨在开发适用于体内化合物的初步努力实验。总体而言，这些发现将有助于进一步研究USP7的更广泛的生物学作用。
