To characterize the interaction of coronaridine congeners with human (h) α3β4 nicotinic acetylcholine receptors (AChRs), structural and functional approaches were used. The Ca(2+) influx results established that coronaridine congeners noncompetitively inhibit hα3β4 AChRs with the following potency (IC50's in μM) sequence: (-)-ibogamine (0.62±0.23)∼(+)-catharanthine (0.68±0.10)>(-)-ibogaine...

18-Methoxycoronaridine (18-MC), a putative anti-addictive agent, has been shown to decrease the self-administration of several drugs of abuse in rats. 18-MC is a potent antagonist at α3β4 nicotinic receptors. Consistent with high densities of α3β4 nicotinic receptors being located in the medial habenula and the interpeduncular nucleus, 18-MC has been shown to act in these regions to decrease...

Advances in computer technology have allowed quantification of the electroencephalogram (EEG) and expansion of quantitative EEG (qEEG) analysis in neurophysiology, as well as clinical neurology, with great success. Among the variety of techniques in this field, frequency (spectral) analysis using Fast Fourier Transforms (FFT) provides a sensitive tool for time-course studies of different...

Drug interaction with P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) may influence its tissue disposition including blood-brain barrier transport and result in potent drug-drug interactions. The limited data obtained using in-vitro models indicate that methadone, buprenorphine, and cannabinoids may interact with human P-gp; but almost nothing is known about drugs of abuse and...

Voacanga africana (Apocynaceae) is a small tropical African tree. The root bark and seeds of this tree contain a number of alkaloids, including ibogaine (a hallucinogenic/aphrodisiac compound in bark), tabersonine (a major constituteent of seeds) and other voacanga alkaloids, traditionally used in Africa for religious purposes. Recently, some kinds of products containing this plant (root bark...

The iboga alkaloid congener, 18-methoxycoronaridine (18-MC), decreases self-administration of multiple drugs of abuse. Here, in a biased procedure, we investigated whether 18-MC would have a similar effect on the acquisition, expression and reinstatement of a cocaine conditioned place preference (CPP) in male Sprague-Dawley rats. While 18-MC attenuated acquisition of a cocaine CPP, it had no...

The novel iboga alkaloid congener 18-methoxycoronaridine (18-MC) is a putative anti-addictive agent that has been shown, in rats, to decrease the self-administration of several drugs of abuse. Previous work has established that 18-MC is a potent antagonist at alpha3beta4 nicotinic receptors. Because high densities of alpha3beta4 nicotinic receptors occur in the medial habenula and the...

18-Methoxycoronaridine (18-MC), a novel iboga alkaloid congener, is a potential treatment for drug addiction. 18-MC has been shown to decrease self-administration of drugs (e.g., morphine, methamphetamine, nicotine) and attenuate opioid withdrawal in rats. In previous studies, systemic pretreatment with 18-MC abolished the sensitized increase in accumbens dopamine levels induced by chronic...

The Fawn-Hooded rat (FH/Wjd) is an inbred alcohol-preferring rat strain, unlike most of the other strains that were selectively bred for high alcohol intake and preference. It was chosen for study some 16 years ago because of a reported mutation that disrupted platelet serotonin function. Although the FH/Wjd rat has high alcohol intake (>5 g/kg/day) and preference (>65%), interbreeding with an...
