The dopamine D-2 antagonist, Ro 22-1319, inhibits the persistent behavioral syndrome induced by iminodipropionitrile (IDPN) in mice.

Abstract

Chronic administration of beta,beta'-iminodipropionitrile causes a persistent syndrome of excitement, choreoathetoid movements, and circling (the "ECC-syndrome") which persists indefinitely after termination of the IDPN injections. Ro 22-1319 is a specific D-2 dopamine receptor antagonist which was recently synthesized to fit a hypothetical model of the D-2 receptor. Ro 22-1319 inhibited several aspects of the ECC-syndrome, although some of its components, such as backward pedaling and forepaw treading reminiscent of the serotonin syndrome, were exacerbated. These results suggest that several neurotransmitter systems may be involved in the ECC-syndrome.
