Study on the metabolism profile of Flavanomarein in Coreopsis tinctoria Nutt
J Sep Sci 2022 Oct;45(20):3827-3837.PMID:35962784DOI:10.1002/jssc.202200301.
Coreopsis tinctoria Nutt. (family Asteraceae) is a popular medicine-food plant, which improves chronic diseases such as hyperlipemia, hypertension, and diabetes. Flavanomarein is the main active component of Coreopsis tinctoria Nutt, in which the blood concentration of volunteers is low and bioavailability is poor. Thus, the understanding of Flavanomarein metabolites and metabolic pathways is significant to clarify its effectiveness. This study systematically studied the metabolites of Flavanomarein by oral and injection. The biological samples (feces, urine, and plasma) were analyzed by ultra-high-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry in negative ion mode. The metabolic law of Flavanomarein in the liver was further verified by a liver microsomal incubation experiment in vitro. A total of 12 metabolites were identified by oral administration while 15 metabolites were detected by injection. It was shown that metabolic pathways include acetylation, hydroxylation, glucuronidation, methylation, dehydrogenation, and so forth. The liver extraction rate of Flavanomarein was 0.08, which means the metabolic stability of Flavanomarein is well in rats' liver microsomes. It is a systematic study on the metabolism of Flavanomarein and provides a metabolic rationale for further in-depth in vivo biotransformation.
Flavanomarein inhibits high glucose-stimulated epithelial-mesenchymal transition in HK-2 cells via targeting spleen tyrosine kinase
Sci Rep 2020 Jan 16;10(1):439.PMID:31949205DOI:10.1038/s41598-019-57360-4.
Flavanomarein (FM) is a major natural compound of Coreopsis tinctoria Nutt with protective effects against diabetic nephropathy (DN). In this study, we investigated the effects of FM on epithelial-mesenchymal transition (EMT) in high glucose (HG)-stimulated human proximal tubular epithelial cells (HK-2) and the underlying mechanisms, including both direct targets and downstream signal-related proteins. The influence of FM on EMT marker proteins was evaluated via western blot. Potential target proteins of FM were searched using Discovery Studio 2017 R2. Gene Ontology (GO) analysis was conducted to enrich the proteins within the protein-protein interaction (PPI) network for biological processes. Specific binding of FM to target proteins was examined via molecular dynamics and surface plasmon resonance analyses (SPR). FM promoted the proliferation of HK-2 cells stimulated with HG and inhibited EMT through the Syk/TGF-β1/Smad signaling pathway. Spleen tyrosine kinase (Syk) was predicted to be the most likely directly interacting protein with FM. Combined therapy with a Syk inhibitor and FM presents significant potential as an effective novel therapeutic strategy for DN.
The protective effects of the native flavanone Flavanomarein on neuronal cells damaged by 6-OHDA
Phytomedicine 2019 Feb;53:193-204.PMID:30668399DOI:10.1016/j.phymed.2018.09.005.
Background: Flavanomarein is the main component of Coreopsis tinctoria Nutt. (C. tinctoria), which is a globally well-known flower tea that has a distinct flavor and many beneficial health effects, such as antioxidant activities. We aimed to explore the effect of Flavanomarein on a 6-hydroxydopamine (6-OHDA)-lesioned cell model of oxidative stress. Methods: In this study, we used 6-OHDA-lesioned PC12 cells and primary cortical neurons to investigate the protective effects of Flavanomarein and its potential mechanism. Results: The results indicated that pretreatment with Flavanomarein (25, 50, or 100 µM for 24 h) significantly increased the cell viability, reduced the lactate dehydrogenase (LDH) release and improved the mitochondrial membrane potential (∆Ψm) and mitochondrial impairment. Additionally, Flavanomarein markedly reduced the gene expression of tumor necrosis factor (TNF)-α and protein kinase C ζ (PKC-ζ), the nuclear translocation of p65, and the levels of p-AMPK-α and acetyl-p53. Flavanomarein also elevated the gene expression of P85α, PKC-β1, and Bcl-2, the protein expression of Sirt1 and ICAD, and the phosphorylation level of AKT. Conclusions: Together, these results suggest that Flavanomarein protects PC12 cells and primary cortical neurons from 6-OHDA-induced neurotoxicity by upregulating the PI3K/AKT signaling pathway and attenuating the nuclear factor kappa B (NF-κB) signaling pathway. Therefore, our study provides evidence that may aid in the development of a potential compound against 6-OHDA toxicity.
[Study on rat intestinal absorption characteristics of total flavonoids from Coreopsis tinctoria]
Zhongguo Zhong Yao Za Zhi 2021 Mar;46(6):1490-1497.PMID:33787148DOI:10.19540/j.cnki.cjcmm.20200706.202.
The rat everted intestinal sac model was adopted to investigate the absorption of total flavonoids from Coreopsis tinctoria in different intestinal segments. Cyaniding-3-O-β-D-glucoside, chlorogenic acid, Flavanomarein, quercetagetin-7-O-β-D-glucoside, iso-okanin, marein and 3,5-dicaffeoylquinic acid which as the major chemical components of total flavonoids from C. tinctoria were selec-ted as the study objects to evaluate the absorption characteristics of each component in different intestinal segments. The results showed that the absorption of seven components of total flavonoids at different intestinal segments was in consistent with zero order absorption rate. The K_a of chlorogenic acid, Flavanomarein, quercetagetin-7-O-β-D-glucoside, isookanin and 3,5-dicaffeoylquinic acid increased with increasing of concentration of total flavonoids(P<0.05), indicating that the intestinal absorption of these five components was passive transport. The K_a of cyaniding-3-O-β-D-glucoside and marein showed a weak concentration dependence, suggesting that the absorption of them may be an positive and passive co-existing mode. The result of absorption in different intestinal segments showed that cyaniding-3-O-β-D-glucoside, chlorogenic acid, Flavanomarein, quercetagetin-7-O-β-D-glucoside, marein and 3,5-dicaffeoylquinic acid were mainly absorbed in ileum, while isookanin was mainly absorbed in jejunum. The total flavonoids of C. tinctoria are selectively absorbed in intestinal tract, the rat everted intestinal sac model can be used to evaluate the multi-component intestinal absorption characteristics of total flavonoids from C. tinctoria.
Simultaneous Determination and Comparison of Phenolic Bioactives among Three Main Kinds of Edible Chrysanthemums
J Chromatogr Sci 2022 Jun 6;60(5):465-471.PMID:35169829DOI:10.1093/chromsci/bmac009.
In this study, we report a simple and reliable high-performance liquid chromatography coupled with diode array detection method for simultaneous and quantitative analysis and comparison of major phenolic compounds dominant phytochemicals in Chrysanthemum morifolium, Florists chrysanthemum and snow chrysanthemum (Coreopsis tinctoria or C. tinctoria). The chromatographic separation was achieved using a reversed phase C18 column with a mobile phase of water [containing 0.1% trifluoroacetic acid (TFA)] and acetonitrile. The major phenolic compounds were completely separated within 16 min at a flow rate of 1.0 mL/min. Flavonoid and phenolic acid profiles of the ethanol extracts of the three flowers were analyzed. The results revealed that C. tinctoria possessed the highest amount of flavonoids (Flavanomarein, flavanokanin, marein and okanin) and relative lower content of phenolic acid (chlorogenic acid and 3,5-dicafeoylquinic acid). The total content of the four flavonoids in C. tinctoria reached 53.99 ± 1.32 mg/g. In particular, the marein content in C. tinctoria was as high as 36.50 mg/g. Flavanomarein was only detected in C. tinctoria, whereas chlorogenic acid and 3,5-dicafeoylquinic acid were abundant in Chrysanthemum morifolium and Florists chrysanthemum. The content of marein in Chrysanthemum morifolium was slightly higher than that in Florists chrysanthemum, whereas no okanin was detected in Florists chrysanthemum under these high-performance liquid chromatography conditions. The results indicated phenolic components differ significantly depending on the cultivar, especially between C. tinctoria and common commercially available chrysanthemums. The method adopted in this study is helpful for quality control of different chrysanthemum species as well as their products, which is essential for usage and functionality clarification.
