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

The effects of tetrahydropapaverine (THP) and papaverine (PAP), an O-methylated analogue, on rat liver alcohol dehydrogenase (L-ADH) and aldehyde-dehydrogenase (L-ALDH) were studied in vitro. The action of THP on these enzymes was also evaluated in vivo in conjunction with its

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 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

1. In the present work, the properties of 3-methyl isoquinoline, 3,4-dihydropapaverine, tetrahydropapaverine and tetrahydropapaveroline were compared with those of papaverine and laudanosine. The work includes functional studies on rat isolated aorta contracted with noradrenaline, caffeine or KCl, and a determination
