Diminazene is a diamidine that is cytotoxic to protozoa, including Trypanosoma, Babesia, and Cytauxzoon. Diamidines, including diminazene, affect a variety of enzymes and modulate interactions between nucleic acids and proteins. Diminazene inhibits diamine oxidase with a Ki value of 13 nM. In Trypanosoma, transport proteins are important in the effectiveness of diminazene. In rats and in vitro, diminazene enhances the enzymatic activity of angiotensin-converting enzyme 2.
