Monoamine receptor interaction profiles of 4-aryl-substituted 2,5-dimethoxyphenethylamines (2C-BI derivatives).

Certain ring-substituted phenethylamines produce psychedelic effects mainly through serotonin 5-HT2A receptors. 2C-BI derivatives, a class of 4'-aryl substituted 2,5-dimethoxyphenethylamines, were tested for binding and activity at monoamine receptors and transporters. Several 2C-BI compounds bound strongly to human serotonergic and adrenergic receptors and to rat and mouse trace amine-associated receptor 1. 2C-BI-8 and 2C-BI-12 activated serotonin 5-HT2A and 5-HT2B receptors at submicromolar concentrations, while only 2C-BI-1 and 2C-BI-7 activated human trace amine-associated receptor 1. 2C-BI-3 and 2C-BI-4 interacted weakly with monoamine transporters. The high affinities at the 5-HT2A receptor suggest a sterically tolerant binding pocket, and potent partial activation by 2C-BI-8 and 2C-BI-12 indicates potential psychedelic effects similar to other 2C compounds.
