Biological Activity for Disulfiram
Disulfiram is an inhibitor of aldehyde dehydrogenase that displays antialcoholism activity. Shown to reversibly stimulate Ca2+-ATPase activity and inhibit V-ATPase (EC50 = 26 μM). Also inhibits expression of MMP-2 and MMP-9 and displays anti-invasive activity. Pyroptosis inhibitor; binds gasdermin D (GSDMD) and inhibits pore formation. Also inhibits SARS-CoV-2 main protease (Mpro; IC50 = 9.35 μM) and inhibits viral replication in Vero cells in vitro.

Recombinant Aldh1 was used in a standard fluorometric reporter assay with NAD+ as a cofactor, reaction velocity measured as relative changes in fluorescence. Disulfiram was added immediately prior to assessing activity. We noted decreasing velocity rates over time supporting this as a time-dependent/ irreversible inhibitor of Aldh enzymes.
Pre-incubation of recombinant enzyme will lead to full depletion of activity. Observed IC50 (initial) at approximately 50 uM.
