Table 1.

25CN-NBOMe phase I and II metabolites, their protonated precursor ion exact masses and retention times (RT) detected in rat urine (RU), human liver microsomes (HLM), and C. elegans (CE). Data were measured with the UltiMate 3000 (Thermo) coupled to the TripleTOF 5600 (AB Sciex) LC-MS system.
