Substituted phenethylamines, including 2C and NBOMe drugs, are potent psychoactive substances with unknown toxicity. In laboratory experiments using rat brain cells and a human cell line, six such drugs (2C-T-2, 2C-T-4, 2C-T-7 and their NBOMe versions) caused concentration-dependent cell death. NBOMe drugs were more toxic than their 2C counterparts, a difference linked to their lipophilicity. The cell damage involved mitochondrial dysfunction, shown by loss of mitochondrial membrane potential and lower ATP levels. Two drugs, 2C-T-7 and 25T7-NBOMe, also disrupted calcium regulation. Although reactive oxygen species did not increase, total glutathione levels fell, indicating oxidative stress. These findings clarify the mechanisms behind these drugs' neurotoxicity.
