Mitoguazone 2HCl | Polyamine biosynthesis inhibitor / SAM decarboxylase inhibitor

Mitoguazone (31959-87-2) is a potent and reversible inhibitor of S-adenosylmethionine decarboxylase (SAMD or AdoMetDC).1,2 SAMD is a component of the polyamine-biosynthetic pathway, thus inhibition may lead to changes in polyamine metabolism.3 Mitoguazone has also been shown to inhibit diamine oxidase and induce spermidine/spermine N-acetyltransferase.4,5 Mitoguazone has been looked at as a potential anti-cancer treatment because of it's ability to inhibit polyamine synthesis.6
