This study identified the metabolites and metabolic pathways of 4-CQA, and demonstrated the effectiveness of 4-CQA and its active metabolites in ameliorating pathological cardiac hypertrophy. The study also found that 4-CQA and 4-O-ferulylquinic acid exhibit similar pharmacokinetic characteristics, making them suitable candidate drugs.
Cryptochlorogenic acid (4-CQA) is a phenolic acid that has antioxidant and anti-inflammatory activities. Our preliminary study found that 4-CQA has a good effect on isoproterenol (ISO)-induced myocardial hypertrophy, while the mechanism remains largely unknown. This study aimed at delineating the metabolites and metabolic pathways of 4-CQA using liquid mass spectrometry and molecular biotechnology, exploring possible active metabolites and the mechanism of myocardial hypertrophy amelioration in H9c2 cells, and finally, investigating the pharmacokinetics of 4-CQA and its active metabolites in vivo. In summary, 56 potential effective metabolites were distinguished in rat urine, feces, plasma samples and heart tissue after intragastric administration of 4-CQA, and the main metabolic reaction types of 4-CQA included hydrogenation, methylation, glucuronidation, sulfation, hydration and their composite reactions in in vivo biotransformation. Besides, 4-CQA and its main active metabolites, caffeic acid and 4-O-feruloylquinic acid, significantly ameliorated pathological cardiac hypertrophy of H9c2 cells treated with ISO based on the Akt/mTOR/HIF-1 alpha pathway. In addition, this study demonstrated that the prototype drugs 4-CQA and 4-O-ferulylquinic acid generally exhibit similar pharmacokinetic characteristics and caffeic acid presents relatively late peak time and low peak concentration in rats, which make them suitable candidate drugs.
