Ketamine, an antagonist of N-methyl-D-aspartate receptor, is extensively employed in pediatric anesthesia. Multiple studies have shown that repeated ketamine exposure induces neuroapoptosis, synaptic changes and cognitive deficits during neurodevelopment. Therefore, it is essential to elucidate the mechanisms of ketamine-induced neurotoxicity and develop therapies to mitigate its harmful...
In this study, we used solid-phase extraction with liquid chromatography-ion trap time-of-flight mass spectrometry (LC-IT-TOF-MS) to analyze 2-fluorodeschloroketamine (2-FDCK) metabolites in human urine. The complete set of oxidative metabolites was identified, with 17 compounds divided into four groups. Furthermore, we examined the hydroxy substitution site after oxidative metabolism with...
