Investigation of major metabolic pathways of SFZ-47 in animals The metabolites of SFZ-47 in rabbit urine following oral administration were separated and detected with HPLC and LC-MS methods. On the basis of the chromatographic behavior and mass spectra of the metabolites as well as biotransformation pathways of drugs with the partial structure of SFZ-47, the hydroxylic derivative 4-(3H-1, 2- dihydro-1-pyrrolizinone-2-methylamino benzyl alcohol and the carboxylic derivative 4-(3H-1, 2-dihydro-1-pyrrolizinone-2-methylamino benzoic acid of SFZ-47 were proposed as two potential metabolites and were synthesized.
