IDPN (3,3'-iminodipropanenitrile) is a neurotoxin with ototoxic and hepatotoxic effects. It causes irreversible movement disorder.[1][2][3]
Ototoxicity
[edit]IDPN has been shown to kill vestibular hair cells, disrupting normal vestibular function, in rats,[4] mice, guinea pigs, and frogs.[5] In rodents, the loss of vestibular function results in balance-related deficits, including circling behavior, retropulsion, and head bobbing, as well as weight loss.[5] Type I hair cells are more sensitive to IDPN toxicity than Type II hair cells.[4] No regeneration of vestibular hair cells was observed, thus these effects can be considered to be irreversible.[4]
IDPN has also been shown to kill cochlear hair cells, affecting auditory function.[6] IDPN-induced hearing loss covered a broad range of frequencies.
