Toxicodynamic insights of 2C and NBOMe drugs - Is there abuse potential?

Toxicology Reports June 1, 2025 Eva Gil-Martins, Daniel José Barbosa, Fernanda Borges et al. 2 citations

Drug use represents a prevalent and multifaceted societal problem, with profound implications for public health, social welfare, and economic stability. To circumvent strict international drug control regulations, there is a growing trend in the development and market introduction of novel psychoactive substances (NPS), encompassing a wide range of compounds with psychoactive properties. This...

The role of mitochondrial dysfunction and calcium dysregulation in 2C-I and 25I-NBOMe-induced neurotoxicity.

Chemico-Biological Interactions April 25, 2025 Eva Gil-Martins, Fernando Cagide, Ana Borer et al. 4 citations

New psychoactive substances (NPS) are designed to evade legal regulation while mimicking the effects of classic illicit drugs such as 3,4-methylenedioxymethamphetamine (MDMA). This category includes phenethylamine derivatives, such as the psychedelic 2C and NBOMe drugs. Given the lack of data regarding the toxicological profile of these substances, the goal of this study was to evaluate the...

Mechanistic Insights into the Neurotoxicity of 2,5-Dimethoxyphenethylamines (2C) and Corresponding N-(2-methoxybenzyl)phenethylamine (NBOMe) Drugs.

Journal of Xenobiotics June 5, 2024 Eva Gil-Martins, Fernando Cagide-Fagín, Daniel Martins et al. 2 citations

Substituted phenethylamines including 2C (2,5-dimethoxyphenethylamines) and NBOMe (N-(2-methoxybenzyl)phenethylamines) drugs are potent psychoactive substances with little to no knowledge available on their toxicity. In the present in vitro study, we explored the mechanisms underlying the neurotoxicity of six substituted phenethylamines: 2C-T-2, 2C-T-4, 2C-T-7 and their corresponding NBOMes....

Unraveling the In Vitro Toxicity Profile of Psychedelic 2C Phenethylamines and Their N-Benzylphenethylamine (NBOMe) Analogues

Pharmaceuticals August 15, 2023 Daniel Martins, Eva Gil-Martins, Fernando Cagide et al. 13 citations

Mescaline derivative (2C phenethylamines) drugs have been modified by the introduction of a N-2-methoxybenzyl group to originate a new series of compounds with recognized and potent psychedelic effects, the NBOMe-drugs. Although they are prevalent in unregulated drug markets, their toxicity profile is still poorly understood, despite several reports highlighting cases of acute intoxication,...

"Ecstasy"-induced toxicity in SH-SY5Y differentiated cells: role of hyperthermia and metabolites.

Archives of Toxicology February 2014 Daniel José Barbosa, João Paulo Capela, Renata Silva et al.

3,4-Methylenedioxymethamphetamine (MDMA; "ecstasy") is a recreational hallucinogenic drug of abuse known to elicit neurotoxic properties. Hepatic formation of neurotoxic metabolites is thought to play a major role in MDMA-related neurotoxicity, though the mechanisms involved are still unclear. Here, we studied the neurotoxicity mechanisms and stability of MDMA and 6 of its major human...

Pro‐oxidant effects of Ecstasy and its metabolites in mouse brain synaptosomes

British Journal of Pharmacology April 21, 2011 Daniel José Barbosa, João Paulo Capela, Jorge M.A. Oliveira et al. 60 citations

BACKGROUND AND PURPOSE: 3,4-Methylenedioxymethamphetamine (MDMA or 'Ecstasy') is a worldwide major drug of abuse known to elicit neurotoxic effects. The mechanisms underlying the neurotoxic effects of MDMA are not clear at present, but the metabolism of dopamine and 5-HT by monoamine oxidase (MAO), as well as the hepatic biotransformation of MDMA into pro-oxidant reactive metabolites is thought...

Synergistic toxicity of ethanol and MDMA towards primary cultured rat hepatocytes.

Toxicology December 5, 2008 Helena Pontes, Carla Sousa, Renata Silva et al.

Ethanol is frequently consumed along with 3,4-methylenedioxymethamphetamine (MDMA; ecstasy). Since both compounds are hepatotoxic and are metabolized in the liver, an increased deleterious interaction resulting from the concomitant use of these two drugs seems plausible. Another important feature of MDMA-induced toxicity is hyperthermia, an effect known to be potentiated after continuous...
