Chloral hydrate, the aldehyde dehydrogenase 2 inhibitor, however had the opposite effects, which could suggest that acrolein contributed to DAS hepatocyte cytotoxicity.

Decadienal-induced cytotoxicity was also more increased by mitochondrial ALDH2 inhibitors than acrolein and was more increased by decreasing mitochondrial NAD+ with rotenone or decreased by increasing mitochondrial NAD+ with oxaloacetate.

This mitochondrial enzyme metabolizes toxic biogenic and environmental aldehydes, including the endogenously produced 4-hydroxynonenal (4HNE) and the environmental pollutant acrolein, and also bioactivates nitroglycerin.
