A small molecule that mimics the metabolic activity of copper-containing amine oxidases (CuAOs) toward physiological mono- and polyamines.

Primary aliphatic biogenic amines have been successfully oxidized using a quinonoid species that mimics the metabolic activity of copper-containing amine oxidase (CuAO) enzymes. Especially, high catalytic performances were observed with aminoacetone, a threonine catabolite, and methylamine, a metabolite of adrenaline, and with the primary amino groups of putrescine and spermidine which are both decarboxylation products of ornithine and S-adenosyl-methionine. Furthermore, contrary to flavine adenine dinucleotide (FAD)-dependent amine oxidase enzymes, no activity was found toward secondary and tertiary amines.
