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

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

Several nitriles have been demonstrated to cause hair cell loss in the inner ear of the rat, but the susceptibility of other species to this toxic effect has not been investigated. Adult male Swiss mice were administered (po) control vehicle

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.

Condensation of beta-amino-alpha,gamma-dicyanocrotononitrile (1) with acetophenone gave 2-amino-4-phenylpenta-1,3-diene-1,1,3-tricarbonitrile (2). The latter product was used in a series of heterocyclization reactions with different reagents such as diazonium salts, hydrazines, hydroxylamines and elemental sulfur to give pyridazine, pyrazole, isoxazole and thiophene derivatives
