New Test Could Speed Detection of Street Drugs and Designer Narcotics
Researchers developed a laboratory method that identifies how different drugs alter cell chemistry, potentially offering law enforcement and regulators a faster way to catalog emerging narcotics. The technique successfully distinguished five substances—including novel synthetic drugs—by their unique metabolic fingerprints, suggesting it could help authorities keep pace with the constantly evolving illegal drug market.
Originaltitel: In vitro metabolomics for the characterization of drugs of abuse and new psychoactive substances in SH-SY5Y cells
<p>New psychoactive substances (NPS) continuously emerge on unregulated drug markets, while in vitro pharmacological profiling at primary targets (e.g., cannabinoid receptor 1) often remains the only means of effect characterization. In this proof-of-concept study, we evaluated a complementary untargeted in vitro metabolomics approach for its ability to distinguish centrally active drugs based on drug-specific alterations of the cellular metabolome. SH-SY5Y neuroblastoma cells were exposed for 18 h to two NPS (MDMB-4en-PINACA and 4-methylmethcathinone) as well as alprazolam, cocaine, and tramadol. Cell extracts were analyzed using normal- and reverse-phase high-performance liquid chromatography coupled to quadrupole time-of-flight mass spectrometry (HPLC-QToF). Multivariate analyses revealed distinct metabolic signatures and clear separation from controls for all compounds except tramadol. These findings demonstrate the feasibility and discriminatory capacity of the established workflow, highlighting its potential as a complementary tool for pharmacological and toxicological characterization of emerging psychoactive substances.</p>
