The main mechanism of immunotoxic effect of acrylonitrile is mediated through inhibition of T lymphocyte esterases and a (3) component of cytochrome c oxidase of immunocyte mitochondrial respiration enzymes, which is important for prevention and treatment of immune disturbances caused by this toxin.

We have investigated the signs of toxicity and effect of equitoxic LD50 doses of saturated and unsaturated aliphatic mono- and dinitriles on tissue and blood cyanide levels, tissue glutathione levels and cytochrome c oxidase activities.
Hepatic and blood cyanide levels 1 h after treatment were highest following malononitrile (MCN) and decreased in the order of propionitrile (PCN) greater than KCN greater than butyronitrile greater than acrylonitrile (VCN) greater than allylcyanide greater than greater than fumaronitrile greater than acetonitrile.

Furthermore, curcumin effectively prevented AN-induced decrease in cytochrome c oxidase activity in both liver and brain.

The cytochrome c oxidase (CcOx) activities in the brains and livers of the rats treated with AN or AN + acetone were significantly lower than those in the normal control rats and the rats treated with DCE, whereas the CcOx activities in the brains and livers of rats with decreased CYP2E1 activity were significantly higher than those in AN-treated rats.
