Abstract:
Aim To investigate the effects of YL- IPA08 on the endogenous metabolites of PTSD model rats by metabolomics methods, and to explore the metabolic pathways and possible mechanisms of YL-IPA08 against PTSD. Methods The rats were randomly divided into control group, PTSD model group, and administration group of PTSD rats induced by forced swimming test, and the treatment group was given YL- IPA08 (2 mg • kg"1) by intragastric gavage for 15 consecutive days. High-performance liquid chromatog- raphy-mass spectrometry (HPLC-MS/MS) technology was used to detect the endogenous differential metabolites and the associated metabolic pathways in rat plasma samples. Targeted quantitative technology was simultaneously applied to detect the concentrations of 18 bile acids in rat plasma. Results Compared with control group, 40 kinds of endogenous metabolites including glutamic acid, proline, valine, arginine, leucine , cholic acid, and creatine showed significant difference, and the concentrations of 11 bile acids significantly increased in plasma of model group as well. Compared with model group, after YL-IPA08 intervention , the above-mentioned potential metabolites ap-peared to return to normal levels. Conclusions Metabolomics analysis reveals that YL-IPA08 has intervention effect on PTSD model rats. The mechanism may be related to the regulation of amino acid metabolism and bile acid metabolism.
