Comprehensive evaluation of the toxicological effects of commonly encountered synthetic cathinones using in silico methods.

Toxicol Res (Camb)

February 2025

Department of Environmental Health Sciences, Istituto di Ricerche Farmacologiche Mario Negri IRCCS, Milan, Italy.

Synthetic cathinones (SCs), a group of new psychoactive substances (NPS), are designer molecules with hallucinogenic and psychostimulatory effects. Although the structural similarities of SCs to amphetamines suggest that they may have similar toxicity profiles to those of amphetamine congeners, little is known about SCs from a toxicological point of view. In the present study, the toxicity profiles of commonly encountered SCs ( = 65), listed in the 2020 Report of the United Nations Office on Drugs and Crime (UNODC), were evaluated using in silico methods.
