An in vitro experiment indicated that DNA single-strand breaks by dimethylarsine were suppressed by the presence of superoxide dismutase and catalase, suggesting that the strand breaks were induced via the production of free-radical species including active oxygens.

In male ICR mice given a single po dose (1500 mg/kg) of DMAA-Na, the activities of mitochondrial superoxide dismutase, glutathione peroxidase, and glucose-6-phosphate dehydrogenase significantly increased at 6 hr or longer after dosing, while cytosolic superoxide dismutase and catalase did not.

Furthermore, the strand breaks after exposure to dimethylarsine were reduced in the presence of catalase and/or superoxide dismutase.

The cytotoxicity of M-2 in HL-60 cells was decreased by the addition of superoxide dismutase, suggesting that the cytotoxicity of M-2 might be due to the production of reactive oxygen species.
