Chemical Synthesis and Biological Evaluation of 18-Methoxycoronaridine (18-MC) as a Potential Anti-addictive Agent

Current Medicinal Chemistry - Central Nervous System Agents August 1, 2001 Upul K. Bandarage, Martin E. Kuehne, Stanley D Glick 8 citations

Ibogaine (1a), one of the psychoactive indole alkaloids found in the root bark of the West African shrub, Tabernanthe iboga, has purported efficacy in treating multiple forms of drug abuse. A single oral treatment with ibogaine or its salts, in the doses of 6 to 19 mg / kg, or a series of four treatments may, respectively, eliminate addictive behavior for up to 6 months or three years In rats,...

18-Methoxycoronardine attenuates nicotine-induced dopamine release and nicotine preferences in rats.

Psychopharmacology October 1, 1998 Stanley D Glick, Isabelle M Maisonneuve, K E Visker et al. 45 citations

Two studies were conducted to assess, in vivo, potential anti-nicotinic effects of the iboga alkaloid ibogaine and its synthetic congener 18-methoxycoronaridine (18-MC). As previously demonstrated for ibogaine, using microdialysis, pretreatment (19h beforehand) with 18-MC (40 mg/kg, i.p.) significantly attenuated nicotine-induced dopamine release in the nucleus accumbens of awake and freely...

Time-dependent interactions between iboga agents and cocaine.

European Journal of Pharmacology October 8, 1997 Isabelle M Maisonneuve, K E Visker, G L Mann et al. 20 citations

The purpose of this study was to clarify the effects of iboga agents on cocaine-induced hyperactivity. Both inhibition and enhancement of cocaine-induced activity by ibogaine have been reported. In the present study, rats were treated with either ibogaine (40 mg/kg, i.p.), noribogaine (40 mg/kg, i.p.), 18-methoxycoronaridine (40 mg/kg, i.p.), or saline, 1 or 19 h prior to the administration of...

Attenuation of alcohol consumption by a novel nontoxic ibogaine analogue (18-methoxycoronaridine) in alcohol-preferring rats.

Pharmacology, biochemistry, and behavior October 1, 1997 Amir H Rezvani, David H Overstreet, Y Yang et al. 78 citations

We previously reported that single administration of ibogaine, an indol alkaloid with antiaddictive properties, dose dependently reduced alcohol intake in three strains of alcohol-preferring rats. The present study examined the effect of different doses of a newly developed nontoxic ibogaine analogue, 18-methoxycoronaridine (18-MC), on alcohol intake. Selectively bred alcohol-preferring rats...

Structurally modified ibogaine analogs exhibit differing affinities for NMDA receptors.

European Journal of Pharmacology August 8, 1996 Richard T. Layer, P Skolnick, C M Bertha et al. 48 citations

Based on both preclinical findings and anecdotal evidence in man, the psychoactive indole alkaloid ibogaine has been suggested to have anti-addictive properties. Previous studies indicate that blockade of NMDA receptors may mediate at least some of the putative anti-addictive actions of ibogaine. The potencies of a series of ibogaine analogs to inhibit...

18-Methoxycoronaridine, a non-toxic iboga alkaloid congener: effects on morphine and cocaine self-administration and on mesolimbic dopamine release in rats.

Brain Research May 6, 1996 Stanley D Glick, Martin E. Kuehne, Isabelle M Maisonneuve et al. 118 citations

Ibogaine, a naturally occurring iboga alkaloid, has been claimed to be effective in treating addiction to opioids and stimulants, and has been reported to inhibit morphine and cocaine self-administration in rats. However, ibogaine also has acute nonspecific side effects (e.g. tremors, decreased motivated behavior in general) as well as neurotoxic effects (Purkinje cell loss) manifested in the...
