title: Alterations in motor behaviour produced by the isomers of 3-PPP in the MPTP-treated marmoset.
abstract: Alterations in motor activity induced by the isomers of 3-(3-hydroxyphenyl)-N,n-propylpiperidine (3-PPP) were studied in normal and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-treated marmosets. In both normal and MPTP-treated animals motor activity was suppressed in a dose-dependent manner by the administration of (-)-3-PPP. In control animals (+)-3-PPP caused biphasic changes in motor activity, namely suppression of activity in low doses but stimulation at higher doses. In contrast (-)-3-PPP only caused locomotor stimulation in MPTP-treated marmosets. (+)-3-PPP may potentially be of use as a post-synaptic dopamine agonist drug in Parkinson's disease.
