The present investigation was undertaken to test the hypothesis that known metabolites of the phenylethylamine hallucinogen 1-(2,5-dimethoxy-4-methylphenyl)-2-aminopropane (DOM) are pharmacologically active. This hypothesis was tested by evaluating the ability of racemic DOM metabolites 2-O-desmethyl DOM (2-DM-DOM) and 5-O-desmethyl DOM (5-DM-DOM) to substitute for the stimulus properties of...

Radioligand-binding studies were performed to ascertain the actions of noribogaine, a suspected metabolite of ibogaine, on opioid receptors. Consistent with previous results, ibogaine showed highest affinity for kappa opioid receptors (Ki = 3.77 +/- 0.81 microM), less affinity for mu receptors (Ki = 11.04 +/- 0.66 microM) and no affinity for delta receptors (Ki > 100 microM). Noribogaine showed...

Assays using radioligands were used to assess the actions of ibogaine and harmaline on various receptor types. Ibogaine congeners showed affinity for opiate receptors whereas harmaline and harmine did not. The Ki for coronaridine was 2.0 microM at mu-opiate receptors. The Kis for coronaridine and tabernanthine at the delta-opiate receptors were 8.1 and 3.1 microM, respectively. Ibogaine,...

The data presented herein appear to strongly implicate the brain 5HT2 receptor as the site-of-action of the hallucinogenic PIAs and LSD. If so, this discovery represents a major step in understanding the molecular pharmacology of hallucinogenic drugs. Using radioactive hallucinogenic drugs, detailed properties of brain 5HT2 receptors indicating the interaction of 5HT2 receptors with GTP-binding...
