We report the toxic effects of 3,4-dimethoxyphenylethylamine (DMPEA), and tetrahydropapaverine (THP) on the rat nigrostriatal system; THP is a tetrahydroisoquinoline compound which may be derived from DMPEA by conjugation of DMPEA and its oxidative metabolite, dimethoxyphenylacetaldehyde; both are potent inhibitors

This review surveys the discovery of endogenous alkaloids in mammals. The formation of morphine in mammalian brain was assumed in 1970. The existence of morphine was demonstrated by radioimmunoassay. Identification of morphine was performed by spectroscopic methods. The isolation of

We report neurotoxic effects of papaverine, tetrahydropapaverine, dimethoxyphenylethylamine (DMPEA), and 1-methyl-4-phenylpyridinium ion (MPP+) on dopaminergic neurons in ventral mesencephalic-striatal co-culture. These compounds have been reported as mitochondrial toxins which may be implicated in the etiology and pathogenesis of Parkinson's disease.

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.

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
