Abstract:
The effect of aspirin eugenol ester(AEE)on the metabolism of rats was investigated to provide theoretical references for the clinical rational use of the drug.Firstly,the appropriate con-centration of AEE suspension was prepared.Wistar rats were randomly divided into three groups:the normal group,the AEE low-dose group(18 mg/kg),and the AEE high-dose group(72 mg/kg).The rats in the dosing group were dosed once daily,and the Wistar rats in the normal group were dosed once daily with an equal volume of 0.5％sodium carboxymethylcellulose solution.The feces and urine were collected after 7 days of continuous gavage,and the feces and urine were ana-lyzed by ultra-performance liquid chromatography-quadrupole time-of-flight tandem mass spec-trometry(UPLC-QTOF-MS/MS)for non-targeted metabolomics and Metabo Analyst 5.0 was used for metabolic pathway enrichment.The results showed that the dose of AEE selected in this experiment was not toxic to the growth of rats.The results of the metabolomics study found that 10 and 8 differential metabolites were identified in rat feces and urine,respectively,involving meta-bolic pathways such as phenylalanine,tyrosine and tryptophan biosynthesis,phenylalanine metabo-lism,steroid hormone biosynthesis,biosynthesis of unsaturated fatty acids,aminosugar and nucleo-tide sugar metabolism,fatty acid biosynthesis,and β-alanine metabolism.AEE had no significant effect on the body weight of rats(P＞0.05),but AEE could affect the metabolism of rat organ-ism.Fecal metabolites were mainly involved in metabolic pathways including unsaturated fatty acid biosynthesis,tyrosine metabolism,fatty acid biosynthesis,and steroid hormone biosynthesis;urina-ry metabolites were mainly involved in metabolic pathways including purine metabolism,fatty acid biosynthesis,arginine,and proline metabolism.Therefore,the metabolic effects of AEE on rats are mainly closely related to the regulation of lipid metabolism,amino acid metabolism,and energy metabolism.The results of this experiment can provide some references for the efficacy and clinical application of AEE in animals.
