NSC 632839 is a nonselective inhibitor of isopeptidases with IC50 values of 45 μM, 37μM, and 9.8μM, respectively for USP2, USP7, and SENP2 [1].

NSC 632839 is reported to have activity against the purified isopeptidases. It inhibits not only DUB (USP2, USP7) but also deSUMOylase (SENP2). It is also shown to inhibit cleavage of an Ub mimetic (z-LRGG-AMC) by transformed fibroblast lysates. However, NSC 632839 has no inhibition to the reporter enzyme PLA2, suggesting the inhibition is selective for isopeptidases [1].

NSC 632839 prevents removal of ubiquitin chains from polyubiquitinated proteins, inhibiting ubiquitin-dependent, proteasome-mediated degradation. It activates apoptosis in an apoptosome-independent manner [2, 3].
