An experimental animal model with cystathioninuria was obtained by the injection of D,L-propargylglycine into rats. The concentrations of D,L-propargylglycine in urine, several tissues and serum at different times after the injection were measured by liquid chromatography-mass spectrometry. The propargylglycine accumulated rapidly in several tissues and serum of the rats, and reached its maximum level at about 2 h after the injection. Approximately 21.2% of the administered propargylglycine was excreted in urine. N-Acetylpropargylglycine was identified as a new metabolite of propargylglycine in urine. The concentration of propargylglycine was 100 times that of N-acetylpropargylglycine in urine.
