ABSTRACT
Aim To study the effect of resveratrol on the metabolism of tryptophan to kynurenine in human liver microsomes.Methods High performance liquid chromatography-tandem mass spectrometry ( LC-MS/ MS) was used to detect the concentration of tryptophan and kynurenine in the microsome incubation system, and the incubation time, tryptophan concentration, and microsomal protein concentration were investigated respectively.The optimal tryptophan incubation system obtained above was used to explore the effect of resveratrol on the kynurenine pathway.Results The optimal incubation time of tryptophan in human liver mi-crosomes in vitro was 90 min,the concentration of tryptophan and liver microsomal protein was 8 mg • L"1 and 1 g • L"1, respectively.The enzyme reaction rate constant Km was 95.91 ±22.29 jxmol • L'1, and the maximum reaction rate V
