Sulfiram is a very weak aldehyde dehydrogenase (ALDH) inhibitor, with an IC50 value of 413 µM against Saccharomyces cerevisiae ALDH. As a photochemical precursor, Sulfiram undergoes photoconversion to form Disulfiram (HY-B0240), a potent ALDH inhibitor. Sulfiram inhibits the dimerization of the extracellular domain fragment (amino acid residues 230-624) of amyloid precursor protein (APP), alters the monomer-dimer equilibrium, induces conformational changes in the fragment, and enhances the production of sAPPalpha via alpha-cleavage of APP. Sulfiram can be used in research related to scabies and Alzheimers disease[1][2].
