title: [Charge-transfer complexes of indolalkylamine and ergoline derivatives].
abstract: Charge-transfer complexes of 1,3,5-trinitrobenzene and pyromellitic dianhydride with indolalkylamines (5-hydroxytryptamine, dimethyltryptamine, etryptamine) and with ergoline derivatives having antiserotonin activity (methysergide, methylergometrine, metergoline, nicotergoline) were studied. The value of the association constant of indole derivatives with trinitrobenzene is influenced by variations on the chain; on the contrary, with pyromellitic dianhydride - only etryptamine and dimethyltryptamine form CT-complexes - the different behaviour can not be correlated with any particular structural characteristics. The association constant values of ergoline derivatives with trinitrobenzene are of the same order of magnitude as that of serotonin; with pyromellitic dianhydride only metergoline and nicotergoline form CT-complexes.
