Metabolic plasticity and the energy economizing effect of ibogaine, the principal alkaloid of Tabernanthe iboga.

Journal of ethnopharmacology August 30, 2012 Roman Paškulin, Polona Jamnik, Tjaša Danevčič et al. 19 citations

Ibogaine, a compound from the iboga plant, temporarily increases cellular energy consumption and carbon dioxide production in a dose-dependent manner, as shown in a yeast model. This energy mobilization paradoxically reduces the ATP pool while simultaneously lowering overall oxidative load. Ibogaine does not act as a direct antioxidant but instead stimulates the cell's own oxidative stress defense systems, leading to metabolic remodeling. The initial energy cost results in improved efficiency of antioxidative systems, reduced oxidative damage, and lower basal metabolic needs. This new metabolic equilibrium saves energy and makes it readily available for extra demands, suggesting benefits for health, stress resistance, and recovery from diseases including addiction.

Ibogaine Has Sex-Specific Plasma Bioavailability, Histopathological and Redox/Antioxidant Effects in Rat Liver and Kidneys: A Study on Females.

Life (Basel, Switzerland) December 23, 2021 Nikola Tatalović, Teodora Vidonja Uzelac, Milica Mijović et al. 8 citations

In female rats, ibogaine treatment produced lower liver glycogen breakdown than previously seen in males, along with dilation of liver blood vessels and increased thiol concentrations six hours after dosing. After 24 hours, liver catalase activity and lipid peroxidation rose while xanthine oxidase activity fell. Kidneys showed mild damage, decreased glutathione reductase, and increased catalase and xanthine oxidase activity at various time points. Ibogaine did not alter antioxidant enzymes in red blood cells. Bioavailability of ibogaine was two to three times higher in females than males. Effects were sex- and tissue-specific, and also dose- and time-dependent.

Effects of ibogaine per os application on redox homeostasis in rat liver and erythrocytes

Archives of Biological Sciences December 5, 2018 Teodora Vidonja Uzelac, Nikola Tatalović, Milica Mijović et al. 7 citations

A single oral dose of ibogaine (1 or 20 mg/kg body weight) in rats did not alter the activities of superoxide dismutases, catalase, glutathione peroxidase, glutathione reductase, or glutathione-S-transferase in the liver or erythrocytes at 6 or 24 hours after administration. However, hepatic xanthine oxidase activity increased in rats receiving 20 mg/kg, indicating faster adenosine turnover. TBARS concentration rose in the 1 mg/kg group after 24 hours, suggesting mild oxidative stress. Histological examination revealed glycogenolytic activity in hepatocytes, peaking at 24 hours in the higher-dose group. Ibogaine influenced hepatic redox homeostasis but not enough to remodel antioxidant enzyme activities within the timeframe studied.
