Curcumae Rhizoma - combined with Sparganii Rhizoma in the treatment of liver cancer: Chemical analysis using UPLC-LTQ-Orbitrap MSⁿ, network analysis, and experimental assessment.

ABSTRACT: Objective: Curcumae Rhizoma-Sparganii Rhizoma (CR-SR) is a traditional botanical drug pair that can promote blood circulation, remove blood stasis, and treat tumors in clinics. The aim of the present study was to investigate the therapeutic material basis and potential mechanisms of CR-SR, CR, and SR for the treatment of liver cancer. Method: The chemical profile analyses of CR-SR, CR, and SR were performed by molecular networking and UPLC-LTQ-Orbitrap MSⁿ. The anti-liver cancer activities of CR-SR, CR, and SR were assessed by using a zebrafish xenograft model in vivo for the first time and detected by the HepG2 cell model in vitro. Combining the network analysis and molecular docking, real-time quantitative polymerase chain reaction (RT-qPCR) experiments were undertaken to further explore the mechanisms of CR-SR, CR, and SR for the treatment of liver cancer. Results: In total, 65 components were identified in CR-SR, CR, and SR. Based on the clusters of molecular networking, a total of 12 novel diarylheptanoids were identified from CR-SR and CR. By combining our results with information from the literature, 32 sesquiterpenoids and 21 cyclic dipeptides were identified from CR-SR, CR, and SR. The anti-liver cancer activities were observed in both the drug pair and the single botanical drugs in vitro and in vivo, and the order of activity was CR-SR > CR > SR. They could downregulate the expression of proto-oncogene tyrosine-protein kinase Src (SRC), epidermal growth factor receptor (EGFR), estrogen receptor-α (ESR1), prostaglandin endoperoxide synthase 2 (PTGS2), and amyloid precursor protein (APP). Conclusion: Taken together, the present study provided an experimental basis for the therapeutic material basis and potential molecular mechanisms of CR-SR, CR, and SR. This study provided a novel insight for objective clinical treatment of liver cancer.

Project description:Recent studies concerning products that originate from natural plants have sought to clarify active ingredients, which both explains the mechanisms of the function and aids in quality control during production. As a traditional functional plant, Curcumae Rhizoma (CR) has been proven to be effective in promoting blood circulation and removing blood stasis. However, the components that play a role in its huge compound library are still unclear. The present study aimed to develop a high-throughput screening method to identify thrombin inhibitors in CR and validate them by in vitro and in vivo experiments. The effect of CR on thrombin in HUVECs cells was determined by ELISA, then an affinity-ultrafiltration-UPLC-Q-Exactive Orbitrap/MS approach was applied. Agatroban and adenosine were used as positive and negative drugs respectively to verify the reliability of the established method. The in vitro activity of the compounds was determined by specific substrate S-2238. The in vivo effect of the active ingredients was determined using zebrafish. Molecular docking was used to understand the internal interactions between compounds and enzymes. ELISA results showed that CR had an inhibitory effect on thrombin. The screening method established in this paper is reliable, by which a total of 15 active compounds were successfully identified. This study is the first to report that C7, 8, and 11 have in vitro thrombin-inhibitory activity and significantly inhibit thrombosis in zebrafish models at a safe dose. Molecular docking studies were employed to analyze the possible active binding sites, with the results suggesting that compound 16 is likely a better thrombin inhibitor compared with the other compounds. Based on the affinity-ultrafiltration-UPLC-Q-Exactive Orbitrap/MS approach, a precisely targeted therapy method using bio-active compounds from CR might be successfully established, which also provides a valuable reference for targeted therapy, mechanism exploration, and the quality control of traditional herbal medicine.

Project description:BackgroundLung cancer has a poor prognosis and a high mortality rate, and patients may develop multidrug resistance. Sparganii Rhizoma-Curcumae Rhizoma (HCSC), the classic herbal drug combination of traditional Chinese medicine (TCM), is commonly used in treating tumors, but its molecular mechanism is still unclear.MethodWe explored the possible mechanisms underlying the antitumor effect of HCSC using network pharmacology. The bioactive components of HCSC and their targets were collected from the TCM Systems Pharmacology (TCMSP) database and PharmMapper. Gene Ontology (GO) and KEGG enrichment analyses were performed; the GeneMANIA platform was used for the functional enrichment analysis of the core targets and their neighboring genes. Molecular docking was performed between the bioactive components and core targets. HCSC freeze-dried powder was prepared, and the bioactive components were verified by liquid chromatography- (LC-) mass spectrometry (MS). Human lung adenocarcinoma H1975 cells were cultured to verify in vitro the molecular mechanism of action of HCSC in treating lung cancer, as predicted by network pharmacology. Finally, we used the Symmap database to predict the relationship between the herb and TCM syndrome.ResultA total of seven bioactive components were identified by network pharmacological analysis. Through enrichment analyses, it was found that the mechanism of action mainly involved mitochondrial-mediated caspase-dependent cell apoptosis signaling pathways. The results of molecular docking showed that the bioactive components in HCSC have a good affinity with the target proteins (ALB, BCL2L1, ESR1, HRAS, MAP2K1, MAPK14, and SIRT1). LC-MS confirmed that formononetin and bisdemethoxycurcumin were present in the HCSC freeze-dried powder, consistent with the prediction. The results of in vitro experiments on NCI-H1975 cells confirmed that HCSC can upregulate the mitochondrial-mediated caspase-dependent apoptosis signaling pathway by inducing the cleavage of caspase-3, caspase-9, and PARP, consistent with the network pharmacology prediction. Further, the qi deficiency and blood stasis associated with TCM syndrome can be treated with HCSC.
