UCH-L1 Inhibitor is an isatin O-acyl oxime compound reported to act as a potent, reversible, competitive, and active site-directed inhibitor of UCH-L1 with greater selectivity over UCH-L3. For a UCH-L3 inhibitor, please see sc-204370.Additionally, UCH-L1 Inhibitor may act to increase proliferation of UCH-L1 expressing tumor cell line SH-SY5Y. Potentially useful for studying the roles of UCH-L1 in cancer, Parkinsons disease, and other neurological disorders. Permeability may vary from cell type to cell type.
