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.

在动物体内主要代谢途径的确定用HPLC和LC-MS对家兔口服SFZ-47后尿中的代谢物进行了分离、检测，根据代谢产物的色谱和质谱行为以及与SFZ-47有类似结构部分的其它药物的代谢途径，推测其羟基衍生物[4-（3H-1，2-二氢-1-吡咯里嗪酮-2-甲基胺基）苯甲醇]与羧基衍生物[4-（3H-1，2-二氢-1-吡咯里嗪酮-2-甲基胺基）苯甲酸]是两种可能的代谢产物，遂用化学方法合成了这两种衍生物。
