Because of the sedative, anxiolytic, and analgesic effects, this herb is currently sold in pharmacies in many countries. However, our understanding of these biological effects at the molecular level is still lacking. Alkaloids detected inE. californicacould be hypothesized to act at GABAAreceptors, which are widely expressed in the brain mainly at the inhibitory interneurons. Electrophysiological studies on a recombinantα1β2γ2GABAAreceptor showed no effect ofN-methyllaurotetanine at concentrations lower than 30 μM. However, (S)-reticuline behaved as positive allosteric modulator at theα3,α5, andα6isoforms of GABAAreceptors. The depressant properties of aerial parts ofE. californicaare assigned to chloride-current modulation by (S)-reticuline at theα3β2γ2andα5β2γ2GABAAreceptors. Interestingly,α1,α3, andα5were not significantly affec...

Phenyl radicals, produced in the cathodic reduction as well as during the photolysis of iodonium salts, were trapped by nitroso-tert-butane ('BuNO) and nitrosodurene (ND) spin traps. However, no phenyl radicals could be detected by ESR during the irradiation of diphenyliodonium iodide, or during its electrochemical reduction, in the presence of C ,. This indicates that prior trapping of phenyl radicals to 'BuNO and ND spin trap agents, their trapping by fullerenes occurred. The radical mechanism of electrochemical and photochemical phenylation of C , using iodonium salts are discussed and these two phenylation techniques are compared.
