Effects of MPTP-like compounds on mitochondrial respiration, activity of NADH-ubiquinone oxidoreductase (complex I) and on ATP synthesis were reported. Mitochondria prepared from mouse whole brains were used. The compounds tested include tetrahydroisoquinoline (TIQ), tetrahydropapaveroline (THP), tetrahydropapaverine (THPV), and salsolinol. TIQ

The in vivo effect of amantadine, chlorpromazine and reserpine on testicular aldehyde dehydrogenase (T-ALDH) was studied as a function of mouse strain. The effect of Leu-enkephalin and tetrahydropapaverine on rodent T-ALDH was also studied in vivo. The in vitro effect

Protective effects of quinic acids from Aster scaber on tetrahydropapaveroline (THP)-induced cell toxicity were evaluated in rat C6 glioma cells. Among 4 quinic acid derivatives tested, (-) 4,5-dicaffeoyl quinic acid (QA3) exhibited the highest protective effect against THP-induced cell toxicity.

Since the discovery of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism, it has been postulated that (a) MPTP-like toxin(s) such as 1,2,3,4-tetrahydroisoquinoline (TIQ) may induce Parkinson's disease. As the neuronal degeneration in MPTP-induced parkinsonism is thought to be caused by the inhibition of the

The inhibitory effects of tetrahydropapaverine on serotonin biosynthesis in serotonin-producing murine mastocytoma P815 cells were investigated. Tetrahydropapaverine at concentration ranges of 5-20 microM decreased serotonin content in a concentration-dependent manner in P815 cells and showed 42.1% inhibition of serotonin content
