The neurotoxic compound crotononitrile has two isomeric forms, cis and trans. We compared the effects of these two isomers isolated by distillation from the commercially available mixture. Adult male Long-Evans rats were administered vehicle control, cis-crotononitrile (80, 100, and 120

Several alkylnitriles are toxic to sensory systems, including the vestibular system, through yet undefined mechanisms. This study addressed the hypothesis that the vestibular toxicity of cis-crotononitrile depends on CYP2E1-mediated bioactivation. Wild-type (129S1) and CYP2E1-null female mice were exposed to cis-crotononitrile

Nitriles are widely used in industry as plastics, solvents, and synthetic intermediates. It has been shown that the thermal degradation of acrylonitrile-based plastics leads to the emission of a great variety of nitriles. Exposure of humans and experimental animals to

Animals exposed to 3,3'-iminodipropionitrile (IDPN) or to several similar nitriles develop a permanent syndrome of behavioral abnormalities. The present work addressed the hypothesis that this syndrome is caused by a toxic effect of these nitriles on the peripheral vestibular system.
