AB  - Ibogaine effects are mediated by cellular receptors, ATP depletion followed by ROS
production and antioxidant enzyme activity elevation in a dose and time dependent manner. Since
the role of KATP channels and β -adrenoceptors in ROS cellular circuit was established here we
explored their role in ibogaine pro-antioxidant effectiveness. Single dose of ibogaine (10 mg/L i.e.,
28.8 µmol/L) was applied to isolated rat uterus (spontaneous and Ca2+-stimulated) and contractility
and antioxidant enzymes activity were monitored during 4 h. Ibogaine increased amplitude and
frequency of spontaneous active uteri immediately after addition that was prevented by propranolol
( 1 and  2 adrenoceptors selective antagonists) and glibenclamide (KATP sensitive channels inhibitor;
only frequency) pre-treatment. In Ca2+-stimulated uteri, ibogaine decreased both amplitude and
frequency after 4 h. Pre-treatment with propranolol abolished ibogaine induced amplitude lowering,
while glibenclamide had no effect. In both types of active uterus, ibogaine induced a decrease in
SOD1 and an increase in CAT activity after 2 h. In Ca2+-stimulated uterus, there was also a decrease
of SOD2 activity after 2 h. After 4 h, SOD1 activity returned to the baseline level, but GSH-Px activity
increased. Pre-treatment with both propranolol and glibenclamide abolished observed changes of
antioxidant enzymes activity suggesting that ibogaine pro-antioxidative effectiveness is β -adrenergic
receptors and KATP channels mediated.

AB  - Ibogaine induces rapid changes in cellular energetics followed by the elevation of antioxidant activities. As shown earlier in male rats, ibogaine treatment with both 1 and 20 mg/kg b.w. per os led to significant glycogenolytic activity in the liver. In this work, female rats treated with the same doses of ibogaine per os displayed lower liver glycogenolytic activity relative to males, dilatation of the central vein and branches of the portal vein, and increased concentration of thiols 6 h after treatment. These changes were followed by increased catalase activity and lipid peroxidation, and decreased xanthine oxidase activity after 24 h. In kidneys, mild histopathological changes were found in all treated animals, accompanied by a decrease of glutathione reductase (after 6 and 24 h at both doses) and an increase of catalase (6 h) and xanthine oxidase activity (6 and 24 h). Ibogaine did not affect antioxidant enzymes activity in erythrocytes. Bioavailability of ibogaine was two to three times higher in females than males, with similar kinetic profiles. Compared to previous results in males, ibogaine showed sex specific effect at the level of antioxidant cellular system. Effects of ibogaine in rats are sex- and tissue-specific, and also dose- and time-dependent.

AB  - Our previous results showed that a single oral dose (1 or 20 mg/kg body weight) of the anti-addiction agent ibogaine induced in rats 6 and 24 h after administration glycogenolytic activity in hepatocytes, followed by a mild oxidative stress. In this work, we examined the in vivo effect of the same doses of ibogaine on rat kidney morphology, antioxidant enzyme (superoxide dismutases (SOD1 and 2), catalase, glutathione peroxidase, glutathione reductase (GR) and glutathione- S-transferase) activities, and oxidative stress (TBARS) and redox (-SH groups) parameters. The dose of 1 mg/kg ibogaine induced an elevation in SOD1 activity and decreased GR activity after 6 and 24 h. GR activity was decreased at 6 and 24 h after 20 mg/kg ibogaine administration, suggesting changed redox homeostasis. After 24 h, we observed an increase in moderate morphological changes, without changes in urinalyses, indicating that kidney function was not measurably affected. Nevertheless, kidney-function monitoring during and following ibogaine use in human subjects is advisable.

AB  - Ibogaine, administered as a single oral dose (1-25 mg/kg body weight), has been used as an addiction-interrupting agent. Its effects persist for up to 72 h. Ex vivo results showed that ibogaine induced cellular energy consumption and restitution, followed by increased reactive oxygen species production and antioxidant activity. Therefore, the aim of this work was to explore the effect of a single oral dose of ibogaine (1 or 20 mg/kg body weight) on antioxidative defenses in rat liver and erythrocytes. Six and 24 h after ibogaine administration, histological examination showed glycogenolytic activity in hepatocytes, which was highest after 24 h in animals that received 20 mg/kg ibogaine. There were no changes in the activities of superoxide dismutases, catalase, glutathione peroxidase, glutathione reductase and glutathione-S-transferase in the liver and erythrocytes after ibogaine treatment, regardless of the dose. Hepatic xanthine oxidase activity was elevated in rats that received 20 mg/kg compared to the controls (p<0.01), suggesting faster adenosine turnover. TBARS concentration was elevated in the group treated with 1 mg/kg after 24 h compared to the controls (p<0.01), suggesting mild oxidative stress. Our results show that ibogaine treatment influenced hepatic redox homeostasis, but not sufficiently to remodel antioxidant enzyme activities at 6 and 24 h post-ibogaine application.

AB  - Ibogaine is an indole alkaloid originally extracted from the root bark of the African rainforest shrub Tabernanthe iboga. It has been explored as a treatment for substance abuse because it interrupts drug addiction and relieves withdrawal symptoms. However, it has been shown that ibogaine treatment leads to a sharp and transient fall in cellular ATP level followed by an increase of cellular respiration and ROS production. Since contractile tissues are sensitive to changes in the levels of ATP and ROS, here we investigated an ibogaine-mediated link between altered redox homeostasis and uterine contractile activity. We found that low concentrations of ibogaine stimulated contractile activity in spontaneously active uteri, but incremental increase of doses inhibited it. Inhibitory concentrations of ibogaine led to decreased SOD1 and elevated GSH-Px activity, but doses that completely inhibited contractions increased CAT activity. Western blot analyses showed that changes in enzyme activities were not due to elevated enzyme protein concentrations but posttranslational modifications. Changes in antioxidant enzyme activities point to a vast concentration-dependent increase in H2O2 level. Knowing that extracellular ATP stimulates isolated uterus contractility, while H2O2 has an inhibitory effect, this concentration-dependent stimulation/inhibition could be linked to ibogaine-related alterations in ATP level and redox homeostasis.
