摘要

1. Untargeted urinary metabolites affected by rifampicin treatment were as follows; testosterone sulfate, androsterone glucuronide, androsterone sulfate, chenodeoxycholic acid 3-sulfate in negative ion mode and their respective de-conjugated metabolites in positive ion modes. 2. In rifampicin-treated group, androsterone sulfate, testosterone sulfate, chenodeoxycholic acid 3-sulfate and cortolone-3-glucuronide were significantly decreased (by 1.5 fold, 8 fold, and 5 fold, 3 fold, respectively) and androsterone glucuronide was significantly increased (by 2.7 fold) compared to controls. 3. Targeted urinary metabolic profiling, Rifampin-induced urine revealed that the increased ions were 16alpha-OH-androstenedione (A-dione), 16alpha-OH-dehydroepiandrosterone (B- (DHEA), 7alpha-DHEA, 7beta-DHEA, 11beta-OH-A-dione, by >1.5-fold and the decreased ions were DHEA, androsterone, etiocholanolone, estrone, beta-cortolone, and allo-tetrahydro cortisone, by <1.5-fold. 4. These results showed the variable metabolic pathway of endogenous urinary steroids induced by PXR activation. 5. In addition, urinary steroid profiling base on the targeted and untargeted metabolomics could be applied as a highly promising biomarker tool in clinical aspects.
