Description
General description
A cell-permeable thiophenylethanone that is shown to inhibit USP7 and USP47 deubiquitinase activity (IC₅₀ = 8.01 & 8.74 µM, respectively), while exhibiting much reduced affinity toward ATXN3, BAP1, and USP1, and displaying no inhibitory activity toward other known PR-619 (Cat. No. 662141) targets (IC₅₀ >50 µM). Both P22077 and PR-619 are shown to increase overall protein polyubiquitination in HEK293T cells in a dose- and time-dependent manner (20 to 150 µM; 0.5 to 20 h), however PR619 treatment results in upregulation of both K⁴⁸- and K⁶³-linked, while P22077 exposure results in mainly enrichment of K⁴⁸-linked polyUb chains.
