USP7-IN-8 (example 81) is a selective ubiquitin-specific protease 7 (USP7) inhibitor with an IC50 of 1.4 μM in an Ub-Rho110 assay. USP7-IN-8 shows no activity against USP47 and USP5. USP7-IN-8 has anticancer effects[1]. USP7 or HAUSP (herpesvirus-associated USP) is a ubiquitin specific protease or a deubiquitylating enzyme that cleaves ubiquitin from its substrates. USP7 is a eubiquitinase (DUB) that controls cell proliferation by altering the stability of Mdm2, p53, PTEN and FOXO4[1].
