Abstract
Objective To develop an ultra performance liquid chromatog-raphy-tandem mass spectrometry ( UPLC -MS/MS ) method for the study of pharmacokinetics of ( S ) -MP 3950 , a novel gastroprokinetic agent candidate in rats.Methods The plasma samples were extracted by liquid -liquid extraction ( LLE ) with ethyl acetate.An ACQUITY UPLC ® BEH C18 column (2.1 mm ×50 mm, 1.7μm) was used with a mobile phase consisting methanol and 5 mmol・ L-1 ammonium acetate with 0.1% formic acid ( v∶v=45∶55 ) .The analysis was performed in multiple reaction monitoring(MRM) mode via positive electrospray ioni-zation source on a triple quadrupole tandem mass spectrometer . The whole analysis time was 3.0 min.The pharmacokinetic parameters were calculated by DAS 2.0 program.Results The method had a lower limit of quantification(LLOQ) of 10 μg・ L-1, linear up to 5000 μg・ L-1. The intra-and inter-day precision(relative standard deviation, RSD) were all less than 7.9%.The accuracy ( relative error , RE ) was from 0.1%to 8.5%.Conclusion The method was proved to be rapid , sen-sitive and accurate for pharmacokinetic study of ( S)-MP 3950 in rats.关键词
