Chloral-derived β-carbolines, which are structurally similar to the dopaminergic neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP, 5), are discussed to contribute to neuronal cell death in idiopathic Parkinson’s disease. The cytotoxic

Separation and stereochemical attribution of the two enantiomers of the neurotoxin 1-trichloromethyl-1,2,3,4-tetrahydro-β-carboline (TaClo) has been achieved by applying chromatography on a chiral phase HPLC column in hyphenation with circular dichr

An improved sensitive assay for the determination of the dopaminergic and serotonergic neurotoxin 1-trichloromethyl-1,2,3,4-tetrahydro-β-carboline (TaClo) is presented, based upon on-line coupling of high-performance liquid chromatography with elect

From the rare West African liana, Dioncophyllum thollonii (Dioncophyllaceae), the known acetogenic tetralones, cis - and trans -isoshinanolone, were isolated. Exemplarily on this material, a new ruthenium-catalyzed oxidative degradation procedure, re

The DNA-damaging effect of the potent dopaminergic neurotoxin ‘TaClo’ (1-trichloromethyl-1,2,3,4-tetrahydro-β-carboline) is reported. After irradiation (300 nm, 350 nm) of cell-free pBR322 DNA in the presence of TaClo, single-strand breaks were

An undescribed fungus of the genus Microsphaeropsis, isolated from the Mediterranean sponge Aplysina aerophoba, produces two new betaenone derivatives (1, 2) and three new 1,3,6, 8-tetrahydroxyanthraquinone congeners (5-7). The structures of the comp
