Abstract. The compound 1-methylphenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxin found as a contaminant in certain street drugs. Individuals using these drugs can develop symptoms similar to those of Parkinson’s disease. 1–3 The symptoms have been attributed to MPTP, which is known to produce Parkinsonian symptoms in some animals 4,5 and which Author: B.

Abstract. 1-Methylphenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxic side product formed in the chemical synthesis of desmethylprodine opioid analgesic, which induces Parkinson disease. The analogues had a different rank order of inhibition of human plasma BzAO compared with the rank order of inhibition of bovine plasma BzAO found previously. MPTP and 1-methyl(2-methylphenyl)-1,2,3,6-tetrahydropyridine (2'-CH 3-MPTP), which are potent nigrostriatal toxins, were weak inhibitors of human plasma by: 3.

The ability of this substance to destroy neurons suggests that an environmental toxin similar to MPTP may be . In animal experiments, only MPTP analogues that preserved the N-methylphenyl-1,2,3,6-tetrahydropyridine structure were active as dopaminergic neurotoxins.

Abstract. Inadvertent self-administration by drug abusers of l-methylphenyl-l,2,3,6- tetrahydropyridine (MPTP), a side reaction product formed during the illicit synthesis of a synthetic narcotic analogue of meperidine, led to the discovery that MPTP produces in humans a movement disorder which closely re- sembles Parkinson’s disease (D avis et al.
