Ubiquitin specific protease 7 (USP7, HAUSP) has become an attractive target in drug discovery due to the role it plays in modulating Mdm2 levels and consequently p53. Increasing interest in USP7 is emerging due to its 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 co-crystallography. Initial hits were identified via fragment-based screening, scaffold-hopping and hybridization exercises. Two distinct sub-series are described along with associated SAR trends, as are initial efforts aimed at developing compounds suitable for in vivo experiments. Overall these discoveries will enable further research into the wider biological role of USP7.
