ABSTRACT
Chlorogenic acid (5-CQA), neochlorogenic acid (3-CQA), and cryptochlorogenic acid (4-CQA), usually simultaneously exist in many traditional Chinese medicines (TCMs). However, insufficient attentions have been paid to the comparative metabolism study on these three isomeric constituents with similar effects on anti-inflammation until now. In this study, a novel strategy was established to perform comparative analysis of their metabolic fates in rats and elucidate the pharmacological mechanism of anti-inflammation. Firstly, diagnostic product ions (DPIs) deduced from the representative reference standards were adopted to rapidly screen and characterize the metabolites in rat plasma, urine and faeces using UHPLC-Q-TOF MS. Subsequently, Network pharmacology was utilized to elucidate their anti-inflammatory mechanism. Consequently, a total of 73 metabolites were detected and characterized, including 50, 47 and 43 metabolites for 5-CQA, 4-CQA and 3-CQA, orderly. Moreover, the network pharmacology study indicated that these three isomeric constituents and their major metabolites with similar in vivo metabolic pathways exerted anti-inflammatory effects through co-owned 20 biological processes, which involved 10 major signal pathways and 159 potential targets. Our study shed light on the similarities and differences of the metabolic profiling and anti-inflammatory activity among these three isomeric constituents and set an example for the further researches on the active mechanism of isomeric constituents existing in TCMs based on comparative metabolism study.
