Abstract

Five phenyl-substituted derivatives and analogues of 1, 2, 3, 4, 5, 6-hexahydroazepino [4, 5- b] indole, 5, a major fragment of ibogaine (1), were synthesized and tested for binding to monoamine transporters, the NMDA receptor-coupled cation channel, and dopamine and opioid receptors. All five derivatives, 9 and 17a-d, displayed 8-10-fold higher affinity at the DA transporter than ibogaine and noribogaine (4). At the serotonin transporter, two ...
