Ten new indole alkaloids (1-10) comprising five ibogan, two aspidosperman, one vincamine, and two bisindole alkaloids, in addition to 32 known alkaloids, were isolated from the stem-bark extract of a Malayan Tabernaemontana corymbosa. The structures of these alkaloids were determined based on analysis of the NMR and MS data and, in five instances (1, 3, 5, 6, 8), confirmed by X-ray diffraction...
A naturally occurring hallucinogenic plant alkaloid, ibogaine has been used as an adjuvant for opiate withdrawal for the past 50 years. In the setting of an escalating nationwide opiate epidemic, use of substances such as ibogaine may also increase. Therefore, familiarity with the mechanisms and potential adverse effects of ibogaine is important for clinicians. We present the case report of a...
Background The use of the hallucinogen ibogaine as an anti-addiction agent has been described in several case reports, dating back to the eighties. The anti-addiction properties of ibogaine have been confirmed in a large body of animal work. Ibogaine has been shown to be effective in reducing withdrawal severity and substance use for a variety of substances, including cocaine and opiates....
Modulation of growth factor signaling pathways in the brain represents a new experimental approach to treating neuropsychiatric disorders such as depression, anxiety, and addiction. Neurotrophins and growth factors exert synaptic, neuronal, and circuit level effects on a wide temporal range, which suggests a possibility of rapid and lasting therapeutic effects. Consequently, identification of...
The iboga alkaloids are a class of naturally occurring and synthetic compounds, some of which modify drug self-administration and withdrawal in humans and preclinical models. Ibogaine, the prototypic iboga alkaloid that is utilized clinically to treat addictions, has been associated with QT prolongation, torsades de pointes and fatalities. hERG blockade as IKr was measured using the whole-cell...
Ibogaine is a psychoactive indole alkaloid found in the African rainforest shrub Tabernanthe Iboga. It is unlicensed but used in the treatment of drug and alcohol addiction. However, reports of ibogaine's toxicity are cause for concern. To review ibogaine's pharmacokinetics and pharmacodynamics, mechanisms of action and reported toxicity. A search of the literature available on PubMed was done,...
Continuous video-electroencephalographic (EEG) monitoring remains the gold standard for seizure liability assessments in preclinical drug safety assessments. EEG monitored by telemetry was used to assess the behavioral and EEG effects of noribogaine hydrochloride (noribogaine) in cynomolgus monkeys. Noribogaine is an iboga alkaloid being studied for the treatment of opioid dependence. Six...
Opioid use disorders (OUD) translate into major health, social, and economic consequences. Opioid agonist medications, which generally require long-term administration, are the mainstay pharmacological treatment of OUD. However, a large proportion of individuals with OUD either refuse or fail to respond to these therapies. Ibogaine, a naturally occurring substance found in the Tabernanthe iboga...
Noribogaine is the long-lived human metabolite of the anti-addictive substance ibogaine. Noribogaine efficaciously reaches the brain with concentrations up to 20 μM after acute therapeutic dose of 40 mg/kg ibogaine in animals. Noribogaine displays atypical opioid-like components in vivo, anti-addictive effects and potent modulatory properties of the tolerance to opiates for which the mode of...
