Biological Activity for PR 619

PR 619 is a broad spectrum, reversible DUB inhibitor. Exhibits limited activity against other proteases. Induces accumulation of polyubiquitinated proteins, but has no direct inhibitory effect on the proteasome. Cytotoxic in HEK293T and colorectal cancer cells. Stabilizes microtubule network in oligodendroglial cells.
