Abstract
Background: Sanwujiao pill (SWJP) is a Chinese herbal preparation widely used in China. It is an essential medicine for treating rheumatism and blood stasis. However, its safety in clinical use has always been the focus of patients because it contains toxic herbs of Aconitum carmichaelii Debx. and A. vilmorinianum Kom.
Objective: To further reveal the pharmaceutical and toxic effect substances and the action mechanism of SWJPs, the metabolites and their pathways of ten Aconitum alkaloids (AAs) in the preparation at different time points after oral administration in eight organs of mice were investigated.
Method: The biosamples were investigated by a four-step strategy of UPLC-Q-TOF-MS /MS technology.
Results: Aconitine (AC), mesaconitine (MA), and hypaconitine (HA) were not detected in any organs. The highest concentrations of the other seven AAs occurred at 0.5 h. Yunaconitine (YAC) was not detected in the brain; all seven AAs had the lowest concentration in the brain, and the metabolism was slow in the stomach. Twelve predicted metabolites were identified, the kidney and stomach were their primary distribution locations, and the most metabolites were found at 0.5h. The main metabolic pathways of the ten AAs were demethylation, deethylation, deoxygenation, hydroxylation, and deacetylation.
Conclusion: This is the first report about the metabolism of ten AAs in SWJPs in mice. Significantly, the metabolic pathways and products of four hidden toxic AAs were analyzed in vivo for the first time. The results were of great significance for the safety and effectiveness of SWJPs in clinical application.
期刊介绍：
Current Drug Metabolism aims to cover all the latest and outstanding developments in drug metabolism, pharmacokinetics, and drug disposition. The journal serves as an international forum for the publication of full-length/mini review, research articles and guest edited issues in drug metabolism. Current Drug Metabolism is an essential journal for academic, clinical, government and pharmaceutical scientists who wish to be kept informed and up-to-date with the most important developments. The journal covers the following general topic areas: pharmaceutics, pharmacokinetics, toxicology, and most importantly drug metabolism.
More specifically, in vitro and in vivo drug metabolism of phase I and phase II enzymes or metabolic pathways; drug-drug interactions and enzyme kinetics; pharmacokinetics, pharmacokinetic-pharmacodynamic modeling, and toxicokinetics; interspecies differences in metabolism or pharmacokinetics, species scaling and extrapolations; drug transporters; target organ toxicity and interindividual variability in drug exposure-response; extrahepatic metabolism; bioactivation, reactive metabolites, and developments for the identification of drug metabolites. Preclinical and clinical reviews describing the drug metabolism and pharmacokinetics of marketed drugs or drug classes.
