Exploring the ethnopharmacological significance of Cynara scolymus bracts: Integrating metabolomics, in-Vitro cytotoxic studies and network pharmacology for liver and breast anticancer activity assessment. JOURNAL OF ETHNOPHARMACOLOGY 2024; 334:118583. [PMID: 39013541 DOI: 10.1016/j.jep.2024.118583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/27/2024] [Revised: 06/25/2024] [Accepted: 07/13/2024] [Indexed: 07/18/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Liver and breast cancers are the most dominant cancer types with high occurrence rates. Artichoke (Cynara scolymus L.) has been reputed for its traditional use in alleviating many liver and gallbladder ailments beside its anticancer activity against various types of cancer cells. AIM OF THE STUDY To demonstrate detailed chemical matrices of the different plant parts and evaluate their cytotoxic activities aiming to unveil the relationship between these activities and the intrinsic metabolites using metabolomic studies, in-vitro experiments and network pharmacology. MATERIALS AND METHODS Chemical profiling of extracts from the different plant parts (stems, leaves, bracts and receptacles) was performed using HPLC/QqQ/MS followed by unsupervised chemometric studies. In-vitro cytotoxic potentials of the extracts were evaluated on breast and liver cancer cell line then an OPLS study using linear regression was conducted. Consequently, a network pharmacology analysis on the most bioactive plant organ was applied. RESULTS Unsupervised chemometric analysis revealed that kaempferol-3-O-α-L-rhamnopyranoside-7-O-β-D-galacturonopyranoside, chrysoeriol-7-rutinoside and 1-caffeoylquinic acid were responsible for the segregation of the bract (CSB) segregated from the rest of the plant organs. Interestingly, CSB extract possessed the highest potential in-vitro cytotoxic activity against both liver and breast cancer cells (IC50 = 1.65 and 1.77 μg/mL). As expected, the aforementioned biomarkers were observed to be the discriminatory cytotoxic metabolites in the constructed supervised chemometric model. Network pharmacology analysis on CSB revealed 27 liver cancer-related metabolites of which, 1-caffeoylquinic acid was the most enriched one contributing to 13% of the total interactions. Furthermore, 38 target genes were involved, the most enriched of which were Aldo-keto reductase family 1 member B1 (AKR1B10) and interleukin-2 (IL-2). KEGG pathway analysis unveiled 23 significantly related pathways including metabolic pathways that possessed the lowest p-value (1.6E-5). CONCLUSION The findings demonstrated that CSB is a significant source of cytotoxic metabolites against breast cancer and liver cancer cell lines, hence, drawing attention to the pharmaceutical and medicinal value of this negligible plant organ and paving the route for insightful research into its exact pharmacological cytotoxic mechanisms.

Abstract
A method was developed to identify and trace the geographic sources of Erigeron breviscapus using high-resolution mass spectrometry and chemometrics. The representative samples were collected from the geographic area of Honghe Dengzhanhua and other areas in Yunnan province and Guizhou province. The data points could be determined well using the PCA and PLS-DA diagram. A total of 46 characteristic compounds were identified from Honghe Dengzhanhua and within Guizhou province, but 37 compounds were different from Honghe Dengzhanhua and other counties in Yunnan province. Two biomarkers were found from three regions. Their structures were inferred as 8-amino-7-oxononanoic acid and 8-hydroxyquinoline, and they had the same molecular composition. This may suggest that a possible synthesis pathway can be proven in the future.

Phytochemical-Based Evidence of the Health Benefits of Bidens Pilosa Extracts and Cytotoxicity. CHEMISTRY AFRICA 2023. [DOI: 10.1007/s42250-023-00626-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Indexed: 03/17/2023]
Abstract
Abstract
Purpose
Bidens pilosa L. is traditionally used as a flavouring agent in foods, in the treatment of diseases, in agriculture as a biopesticide and herbicide, and in the phytoremediation of soils contaminated with heavy metals. The vast range of uses of B. pilosa for a variety of purposes is questionable, hence motivating the objectives of this study, which are to assess the cytotoxicity, health benefits, and/or risks of B. pilosa using chemical-based evidence.
Methods
A real-time cell analysis (xCELLigence system), ultra-high-performance liquid chromatography coupled to a quadrupole-time-of-flight mass spectrometer, high-performance liquid chromatography with a diode array detector, and chemical-based spectrophotometric methods were adopted in the study.
Results
High concentrations of the ethanol extracts exhibited cytotoxic activity on HepG2 (cancerous), and Vero (non-cancerous) cell lines, whereas the water extracts promoted cell proliferation at selected concentrations. The chemical profiling enabled the separation as well as characterisation of 137 phytochemicals. These were mainly phenolic acids, flavonoids, fatty acids, coumarins, and furanocoumarins. There was no toxic compound identified.
Conclusion
The ethanol extracts are generally more potent and exhibit stronger antioxidant activity and cytotoxicity, probably due to the presence of more flavonoids and phenolic acids, validating the uses of B. pilosa and its relevance as a source of functional phytochemicals.

MOLECULES (BASEL, SWITZERLAND) 2022; 27:molecules27248912. [PMID: 36558046 PMCID: PMC9782900 DOI: 10.3390/molecules27248912] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 12/08/2022] [Accepted: 12/11/2022] [Indexed: 12/23/2022]
Abstract
The present study investigated phenolic compounds, antioxidant, antidiabetic, and the anti-inflammatory potentials of methanolic and chloroform extracts of Eriocephalus africanus. The methanolic extract included, polyphenols (112 ± 2.81 mg gallic acid equivalent (GAE)/g), flavonols (76.12 ± 7.95 mg quercetin equivalents (QE)/g); antioxidant capacity (Ferric Reducing Antioxidant Power (FRAP) (752.64 ± 89.0 μmol of ascorbic acid equivalents (AAE) per g dry weight (µmol AAE/g), 2,2-dyphenyl-1-picrylhydrazyl (DPPH) (812.18 ± 51.12 Trolox equivalents per gram of dry mass of plant extracts (μmol TE/g), TEAC (631.63 ± 17.42 µmol TE/g)), while the chloroform extract included polyphenols (39.93 ± 1.36 mg GAE/g), flavonols (44.81 ± 3.74 mg QE/g); antioxidant capacity, DPPH (58.70 ± 5.18 µmol TE/g), TEAC (118.63 ± 3.74 µmol TE/g) and FRAP (107.10 ± 2.41 µmol AAE/g). The phytochemicals profiling performed by UPLC-ESI-QTOF-MS revealed some important polyphenols, predominantly flavonoids, that could be responsible for the antioxidant capacity and biological effects. Both extracts demonstrated a dose-dependent manner of the alpha-glucosidase inhibition with an IC50 between 125 and 250 μg/mL for methanolic extract, while the chloroform extract was at 250 μg/mL. In the L6 myoblasts and C3A hepatocytes, the methanolic extract slightly increased the utilization of glucose, and both extracts exhibited a dose-dependent increase in the glucose uptake in both cell types without significantly increasing the cytotoxicity. Furthermore, both extracts exhibited an anti-inflammatory potential and the findings from the present study could serve as a baseline for further research in the development of pharmaceutical agents.

Abstract
1. Breviscapine was an active ingredient of flavonoid glycosides. Our present study was conducted to evaluate the impact of breviscapine on the pharmacokinetics of losartan and its active metabolite E-3174, and that relationship with the gene polymorphism of CYP2C9 in healthy Chinese volunteers, to provide a basis for clinical rational drug use.2. The genotypes of 217 healthy Chinese subjects were determined using PCR-RFLP. Twelve healthy subjects were selected and were known CYP2C9 genotypes (six CYP2C9*1/*3 and six CYP2C9*1/*1) in a two-phase randomised crossover design study. These subjects were given daily doses of 120 mg (40 mg, three times a day) of breviscapine or a placebo for 14 days, followed by 50 mg losartan on day 15.3. Compared with individuals carrying the CYP2C9*1/*1 genotype, the CYP2C9*1/*3 genotype showed an increase in the AUC(0-36) (833.6 ± 379.8 ng h ml-1 vs. 526.1 ± 140.1 ng h ml-1, p < 0.05) and a decrease in the MR (the metabolic ratio of losartan, AUCE-3174/AUClosartan) (2.67 ± 1.40 vs. 4.56 ± 0.83, p < 0.05) of losartan during the placebo treatment phase. Individuals with genotype CYP2C9*1/*3 showed a significant increase in AUC(0-36) (2335 ± 851.8 ng h ml-1 vs. 1927 ± 949.5 ng h ml-1, p < 0.05) and AUC(0-∞) (2363 ± 875.6 ng h ml-1 vs. 1966 ± 966.1 ng h ml-1, p < 0.05) of E-3174 after breviscapine treatment compared to the placebo group.4. In healthy subjects, breviscapine had no significant effect on the pharmacokinetics of losartan. The activity of CYP2C9 enzyme to losartan metabolism was more significant in subjects with CYP2C9*1/*3 than those with CYP2C9*1/*1 genotype.

Abstract
Mentha spp. are used in the food and pharmaceutical industry; the plants are characterized by natural interspecies hybridization. In this study, knowledge of the chemical composition of Mentha spp. was broadened by focusing on plants grown in a geographically small region of Estonia. The antibacterial activity of Mentha spp. essential oils and water extracts was evaluated. Polyphenolic water extracts of M. × villosa Huds., M. × suaveolens Ehrh., and M. × gracilis Sole were tested for the first time on Escherichia coli and Staphylococcus aureus. Leaves of cultivated and wild-grown plants ( n = 33) were collected. The microdistilled essential oil composition reflected the diversity within the genus Mentha. Determined by gas chromatography-mass spectrometry (MS), major compounds were cis-piperitone oxide, carvone, linalool, menthol, and menthofuran. Based on high-performance liquid chromatography-ultraviolet-MS/MS analyses of the water extracts, no species-specific polyphenolic compounds could be proposed. Abundant polyphenols were rosmarinic acid, salvianolic acid B, and eriocitrin. Essential oils exhibited antibacterial activity on E. coli and S. aureus by the broth dilution method. Water extracts showed activity only against S. aureus. This study supports the use of Mentha spp. as health-promoting ingredients in food. However, further studies are still needed to widen the knowledge of the chemical composition of these plants.

Abstract
Herba Erigerontis injection (HEI) is an aqueous solution derived from whole plants of Erigeron breviscapus, which may be co-administered with warfarin to treat cardiovascular and cerebrovascular disorders. This research was conducted to make sure whether HEI would affect anticoagulation of warfarin to guarantee reasonable medication. The pharmacodynamic study was designed to measure prothrombin time (PT) and activated partial thromboplastin time (APTT) values, and international normalized ratio (INR) values were calculated. For pharmacokinetic study, ultra performance liquid chromatography-tandem mass spectrometer (UPLC-MS/MS) technology was applied to measure plasma concentrations of warfarin enantiomers. The influence of HEI on plasma protein binding rate of warfarin was assessed by ultrafiltration. Pharmacodynamic study demonstrated that both HEI alone and co-administered with warfarin could increase PT and INR values significantly (P < .01), whereas the APTT values were unaffected (P > .05). Pharmacokinetic study manifested that Cmax , AUC and t1/2 prolonged significantly (P < .01) for R/S-warfarin in presence of HEI. Low (3.6 mL/kg), medium (7.2 mL/kg) and high (10.8 mL/kg) doses of HEI could decrease plasma protein binding rate of warfarin significantly (P < .01). The results mean that HEI can potentiate the anticoagulant response of warfarin through both pharmacodynamics and pharmacokinetics.

Abstract
Caffeoylquinic acids (CQAs) are a broad class of secondary metabolites that have been found in edible and medicinal plants from various families. It has been 100 years since the discovery of chlorogenic acid in 1920. In recent years, a number of naturally derived CQAs have been isolated and structurally elucidated. Accumulated evidence demonstrate that CQAs have a wide range of biological activities, such as antioxidation, antibacterial, antiparasitic, neuroprotective, anti-inflammatory, anticancer, antiviral, and antidiabetic effects. Up to date, some meaningful progresses on the biosynthesis and total synthesis of CQAs have also been made. Therefore, it is necessary to comprehensively summarize the structure, biological activity, biosynthesis, and chemical synthesis of CQAs. This review provides extensive coverage of naturally occurring CQAs discovered from 1990 until 2020. Modern isolation techniques, chemical data (including structure, biosynthesis, and total synthesis), and bioactivity are summarized. This would be helpful for further research of CQAs as potential pharmaceutical agents.

Abstract
This study aimed to investigate the integrated pharmacokinetics (PK) of Dengzhanxixin injection (EBI) in rats by combination of multicomponent PK and pharmacological assays. First, the protective effects of 13 main components (30 mg kg−1 per day, i.v. for 7 days) on isoprenaline-induced myocardial infarction (MI) in mice were evaluated by measuring electrocardiogram and serum creatine kinase (CK) activity, and observing cardiac pathological changes. Second, the quantitative analysis method of the main components in rat plasma was established and applied to pharmacokinetic study of EBI in rats (0.72 mL kg−1 and 3.2 mL kg−1 of 10 times concentrated EBI, single i.v.). Third, based on the multicomponent PK and anti-MI effects, PK markers were selected, and the integrated PK of EBI in rats were investigated using “plasma drug concentration sum method” and “AUC weighting integrated method”. In the in vivo anti-MI study, the ST segment elevation seldom occurred and the serum CK significantly decreased (P < 0.05 vs. model group); additionally tissue sections showed mild edema and inflammatory infiltration, and there was a little loss of striations in heart tissue in scutellarin, 3-caffeoylquinic acid (3-CQA), apigenin-7-O-glucuronide (A-7-O-G) and 4,5-dicaffeoylquinic acid (4,5-diCQA) treated groups, suggesting that scutellarin, 3-CQA, A-7-O-G and 4,5-diCQA were the main anti-MI effective substances. In the PK study, the systematic exposure level of scutellarin, erigoster B, 3,4-diCDOA (or 4,9-diCDOA), A-7-O-G, and 4,5-diCQA is relatively high. Considering the contents in EBI, anti-MI efficacy and PK properties of each component, scutellarin, 3-CQA, A-7-O-G, erigoster B, 3,4-diCDOA (or 4,9-diCDOA) and 4,5-diCQA were selected as pharmacokinetic markers to characterize the integrated pharmacokinetic behavior of EBI in vivo. The integrated pharmacokinetic study of EBI in rats could reveal the overall in vivo process and improve the safety and rationality of the clinical use of EBI. The integrated pharmacokinetic study of Dengzhanxixin injection in rats could reveal its overall in vivo process.![]()

JOURNAL OF ETHNOPHARMACOLOGY 2018; 224:429-440. [PMID: 29783016 DOI: 10.1016/j.jep.2018.05.022] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/09/2017] [Revised: 05/14/2018] [Accepted: 05/17/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Cerebrovascular diseases (CBVDs), characterized by striking morbidity and mortality, have become the most common life-threatening diseases. The existing drugs of CBVDs target one or a few of pathogenic factors, the efficacy of which is limited because of the complexity of CBVDs. Traditional Chinese medicine (TCM), featured by multi-component and multi-target endows the great effectiveness in CBVDs treatment. For instance, Erigeron breviscapus (vant.) Hand. Mazz. (Erigeron breviscapus) has been used to treat CBVDs for a long time and the efficacy has been verified through years' of practice. Nevertheless, the mechanisms of Erigeron breviscapus for treating CBVDs are still unclear. THE AIM OF THE STUDY Systematically decipher the mechanisms of Erigeron breviscapus for treating CBVDs. MATERIALS AND METHODS The systems pharmacology approach is utilized by integrating ADME pharmacokinetic screening, target fishing, protein-protein interaction (PPI), network analysis and in vitro experiments verification. RESULTS First, 14 potentially active molecules were screened out through in silico ADME pharmacokinetic evaluation, most of which have been reported with excellent biological activities. Then 169 targets of active molecules were read out using our in-house softwares, systems drug targeting (sysDT) and Weighted Ensemble Similarity(WES). We found that the targets of the active compounds were significantly enriched to the CBVDs therapeutic targets by analyzing their biological processes and protein-protein interactions (PPIs). A multi-layer network analysis including compound-target network, target-pathway network and "CBVDs pathway" indicated that the Erigeron breviscapus exerts a protective effect on CBVDs via regulating multiple pathways and hitting on multiple targets. Meanwhile in vitro experiments confirmed that the stigmasterol, scutellarein, and daucosterol from Erigeron breviscapus increased the MEK and PLCγ proteins levels, and decreased the expression of Bax, PI3K, and eNOS, which led to the cell survival, proliferation and contraction. CONCLUSION The approach used in this work offers a new exemplification for systematically understanding the mechanisms of herbal medicines, which will give an impulse to the CBVDs drug development.

Abstract
Erigeron breviscapus, a traditional Chinese medicine, is clinically used for the treatment of occlusive cerebral vascular diseases. We developed a sensitive and reliable ultra-performance liquid chromatography-electrospray-tandem mass spectrometry (UPLC-ESI-MS/MS) method for simultaneous quantitation of chlorogenic acid, scutellarin, and scutellarein, the main active constituents in Erigeron breviscapus, and compared the pharmacokinetics of these active ingredients in sham-operated and middle cerebral artery occlusion (MCAO) rats orally administrated with Erigeron breviscapus extract. Plasma samples were collected at 15 time points after oral administration of the Erigeron breviscapus extract. The levels of chlorogenic acid, scutellarin, and scutellarein in rat plasma at various time points were determined by a UPLC-ESI-MS/MS method, and the drug concentration versus time plots were constructed to estimate pharmacokinetic parameters. The concentration of chlorogenic acid in the plasma reached the maximum plasma drug concentration in about 15 min and was below the limit of detection after 4 h. Scutellarin and scutellarein showed the phenomenon of multiple absorption peaks in sham-operated and MCAO rats, respectively. Compared with the sham-operated rats, the terminal elimination half-life of scutellarein in the MCAO rats was prolonged by more than two times and the area under the curve of each component in the MCAO rats was significantly increased. The results showed chlorogenic acid, scutellarin, and scutellarein in MCAO rats had higher drug exposure than that in sham-operated rats, which provided a reference for the development of innovative drugs, optimal dosing regimens, and clinical rational drug use.

Identification of anti-inflammatory constituents from Kalimeris indica with UHPLC-ESI-Q-TOF-MS/MS and GC-MS. JOURNAL OF ETHNOPHARMACOLOGY 2015; 165:39-45. [PMID: 25701747 DOI: 10.1016/j.jep.2015.02.034] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/19/2014] [Revised: 02/02/2015] [Accepted: 02/10/2015] [Indexed: 06/04/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kalimeris indica is a Miao׳s medicinal plant in Guizhou province of China employing to treat various inflammation-related diseases in clinical. The study aims to determine the active fractions of K. indica for its anti-inflammatory activity and to identify their chemical constituents. MATERIAL AND METHODS The dried K. indica herb was extracted with 50% aqueous ethanol and then successively separated with macroporous resin and MCI column chromatography to give five fractions (A-E). The anti-inflammatory effects were determined by measuring the NO and TNF-α production in murine macrophage RAW 264.7 cells after exposure to LPS. The chemical constituents of the anti-inflammatory fractions were analyzed by the method of UHPLC-ESI-Q-TOF/MS or GC-MS. RESULTS Five fractions (A-E) of different polarities were prepared from the 50% ethanol extract. Factions C and E showed significant inhibition of NO and TNF-α production. Six constituents, namely 3,4-dicaffeoylquinic acid (1), 3,5-dicaffeoylquinic acid (2), 1,5-dicaffeoylquinic acid (3), rutin (4), 1-malonyl-3,5-dicaffeoylquinic acid (5), and 4,5-dicaffeoylquinic acid (6) were identified from the active fraction C by UHPLC-ESI-Q-TOF/MS. Four compounds including 13-tetradecenal (7), (Z,Z)-9,12-octadecadienoic acid (8), (3α)-12-oleanen-3-yl acetate (9), and (+)-3-oxo-urs-12-en-24-oic acid methyl ester (10) were identified from the active fraction E by GC-MS. CONCLUSION K. indica possessed pronounced anti-inflammatory effect. Dicaffeoylquinic acids and their dirivatives, rutin, as well as oleanolic and fatty acid derivatives are the major constituents and possibly the anti-inflammatory principles of the active fractions of K. indica. All the compounds were identified in K. indica for the first time. The work provided evidence for further development and utilization of K. indica and formed a basis for the establishment of quality control methods and standards for K. indica and its pharmaceutical preparations.

Abstract
The aim of the study was to obtain transformed roots of Rhaponticum carthamoides and evaluate their phytochemical profile. Hairy roots were induced from leaf explants by the transformation of Agrobacterium rhizogenes strains A4 and ATCC 15834. The best response (43%) was achieved by infection with A4 strain. The effects of different liquid media (WPM, B5, SH) with full and half-strength concentrations of macro- and micronutrients on biomass accumulation of the best grown hairy root line (RC3) at two different lighting conditions (light or dark) were investigated. The highest biomass (93 g L(-1) of the fresh weight after 35 days) was obtained in WPM medium under periodic light. UPLC-PDA-ESI-MS(3) and HPLC-PDA analyses of 80% aqueous methanol extracts from the obtained hairy roots revealed the presence of eleven caffeoylquinic acids and their derivatives and five flavonoid glycosides. The production of caffeoylquinic acids and their derivatives was elevated in hairy roots grown in the light. Only light-grown hairy roots demonstrated the capability for the biosynthesis of such flavonoid glycosides as quercetagetin, quercetin, luteolin, and patuletin hexosides. Chlorogenic acid, 3,5-di-O-caffeoylquinic acid and a tentatively identified tricaffeoylquinic acid derivative were detected as the major compounds present in the transformed roots.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Erigerontis Herba is widely used as a traditional Chinese medicine and is commonly used for neuroprotection and vascular protection. AIM OF STUDY In this study, the vasodilator effects of Erigerontis Herba (DZXX) were investigated using rat isolated aorta rings. MATERIAL AND METHOD The involvement of endothelium in the vasorelaxation was studied by comparing response of endothelium-intact and endothelium-denuded aorta rings which precontracted with U46619. The involvement of K(+) channels was studied by pretreatment of the aorta rings with various K(+) channel inhibitors. The involvement of Ca(2+) channel was studied by incubating aorta rings with Ca(2+)-free solution, primed with U46619 prior to elicit contraction by addition of Ca(2+) solution. RESULTS DZXX (0.2-2mg/ml) induced a concentration-dependent relaxation on U44619-precontracted aorta rings with EC50 of 0.354±0.036mg/ml. Removal of endothelium or pretreatment with a BKCa inhibitor iberiotoxin, KIR inhibitor barium chloride or Kv inhibitor 4-aminopyridine produced no effect on the DZXX-induced vasorelaxation. However, pretreatment with a KATP inhibitor glibenclamide or a non-selective K(+) channel inhibitor tetraethylammonium produced significant inhibition on the DZXX-induced vasorelaxation by 29.9% and 21.3%, respectively. Pretreatment with DZXX (0.4, 1.2 and 2mg/ml) produced a concentration-dependent inhibition on Ca(2+)-induced vasoconstriction. CONCLUSIONS These results suggest that the vasodilator effect of DZXX was endothelium-independent, mediated by decreasing the influx of Ca(2+) by calcium channel inhibition and increasing the influx of K(+) by opening of a KATP channel.

In vitro inhibitory effects of scutellarin on six human/rat cytochrome P450 enzymes and P-glycoprotein. Molecules 2014; 19:5748-60. [PMID: 24802986 PMCID: PMC6271944 DOI: 10.3390/molecules19055748] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2014] [Revised: 04/25/2014] [Accepted: 04/25/2014] [Indexed: 02/08/2023] Open
Abstract
Inhibition of cytochrome P450 (CYP) and P-glycoprotein (P-gp) are regarded as the most frequent and clinically important pharmacokinetic causes among the various possible factors for drug-drug interactions. Scutellarin is a flavonoid which is widely used for the treatment of cardiovascular diseases. In this study, the in vitro inhibitory effects of scutellarin on six major human CYPs (CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4) and six rat CYPs (CYP1A2, CYP2C7, CYP2C11, CYP2C79, CYP2D4, and CYP3A2) activities were examined by using liquid chromatography-tandem mass spectrometry. Meanwhile, the inhibitory effects of scutellarin on P-gp activity were examined on a human metastatic malignant melanoma cell line WM-266-4 by calcein-AM fluorometry screening assay. Results demonstrated that scutellarin showed negligible inhibitory effects on the six major CYP isoenzymes in human/rat liver microsomes with almost all of the IC50 values exceeding 100 μM, whereas it showed values of 63.8 μM for CYP2C19 in human liver microsomes, and 63.1 and 85.6 μM for CYP2C7 and CYP2C79 in rat liver microsomes, respectively. Scutellarin also showed weak inhibitory effect on P-gp. In conclusion, this study demonstrates that scutellarin is unlikely to cause any clinically significant herb-drug interactions in humans when co-administered with substrates of the six CYPs (CYP1A2, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4) and P-gp.

Abstract
Abstract
Objectives
This in vitro investigation was designed to examine potential neuroprotection by dicaffeoylquinic acids (diCQAs) extracted from a traditional Chinese medicinal herb herba erigerontis and their effects against the toxicity induced by β-amyloid peptide (Aβ25–35).
Methods
The neuroblastoma SH-SY5Y cell line was treated with Aβ or 3, 4-diCQA, 3, 5-diCQA or 4, 5-diCQA. 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) reduction was assayed by spectrophotometrical method, lipid peroxidation (malondialdehyde) on the basis of the level of thiobarbituric acid-reactive substance, the activity of superoxide dismutase by the xanthine oxidase procedure, the frequency of apoptosis by flow cytometry, and the levels of α3 and α7 nicotinic acetylcholine receptor (nAChR) subunit proteins by Western blotting.
Key findings
When the cells were exposed to Aβ25–35, MTT reduction declined, oxidative stress and apoptosis were enhanced, and the expression of α3 and α7 nAChR subunit proteins was lowered. Expression of the α7 nAChR subunit protein was increased by all three diCQAs, and the level of α3 was increased by 3, 5-diCQA and 4, 5-diCQA. Significantly, pretreatment with diCQAs attenuated the neurotoxic effects of Aβ25–35, a neuroprotective effect in which the upregulation of α7 and α3 nAChR may be involved.
Conclusion
The diCQAs exert a protective effect on Aβ-induced neurotoxicity in SH-SY5Y cells and a potential underlying mechanism involving stimulation of nAChRs.

[PMID: 23868670 DOI: 10.1002/jssc.201300235] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2013] [Revised: 05/05/2013] [Accepted: 05/29/2013] [Indexed: 11/10/2022]
Abstract
LC-MS/MS is currently the most selective and efficient tool for the quantitative analysis of drugs and metabolites in the pharmaceutical industry and in clinical assays. However, phase II metabolites sometimes negatively affect the selectivity and efficiency of the LC-MS/MS method, especially for the metabolites that possess similar physicochemical characteristics and generate the same precursor ions as their parent compounds due to the in-source collision-induced dissociation during the ionization process. This paper proposes some strategies for examining co-eluting metabolites existing in real samples, and further assuring whether these metabolites could affect the selectivity and accuracy of the analytical methods. Strategies using precursor-ion scans and product-ion scans were applied in this study. An example drug, namely, caffeic acid phenethyl ester, which can generate many endogenous phase II metabolites, was selected to conduct this work. These metabolites, generated during the in vivo metabolic processes, can be in-source-dissociated to the precursor ions of their parent compounds. If these metabolites are not separated from their parent compounds, the quantification of the target analytes (parent compounds) would be influenced. Some metabolites were eluted closely to caffeic acid phenethyl ester on LC columns, although long columns and relatively long elution programs were used. The strategies can be utilized in quantitative methodologies that apply LC-MS/MS to assure the performance of selectivity, thus enhancing the reliability of the experimental data.

Abstract
INTRODUCTION A flavonoid-enriched extract (FEE) of Polygonum orientale was reported to show cardioprotective effect but only very few compounds were reported to contribute to the effect. Identification of compounds interacting with the target cardiac cell is important for the understanding of active compounds. OBJECTIVE To develop an efficient method for the screening of potential active compounds directly acting on the target cardiac cell in FEE and to structurally characterise these compounds. METHODOLOGY Flavonoid-enriched extract was prepared by extraction of the plant with water, addition of ethanol to the solution to remove polysaccharides and proteins, and removal of tannins by a polyamide column chromatography. Cell extraction was conducted on a cardiac h9c2 cell and the solution containing compounds released from the cell were desalted by solid phase extraction. Compounds present in the cell extract were detected by ultra-performance liquid chromatography (UPLC) and targeted multi-reaction monitoring (MRM), while their structures were characterised by UPLC-photodiodide array (PDA)-electrospray ion source (ESI)-MS/MS investigations of the FEE. RESULTS Twenty-three potentially active phenolics including ten flavonoid C-glycosides and six flavonoid O-glycosides have been identified from the 40 compounds screened in the cell extract. Among these compounds, three were new and nine were identified from this plant for the first time. Strategies for the structural characterisation of flavonoid glycosides were also discussed. CONCLUSION The study has shown that FEE contains the flavonoid as its major principles and the coupling of UPLC-PDA-ESI-MS/MS and targeted UPLC-MRM with target cell extraction is an efficient method for the screening and structural characterisation of potential active compounds.

Abstract
RATIONALE Acylated monosaccharide residues are structural subunits of natural products or synthetic intermediates that have received much attention in past years. Determination of the acylation sites of these residues still relies heavily on the comparison of their characteristic NMR signals with those of known standards and synthesized acylated glycosides. It is important to develop a rapid analytical method for determining the acylation sites for these compounds, and this is described in this study. METHODS Six known polyphenolic glycosides were used for the electrospray ionization and collision-induced dissociation tandem mass spectrometry (ESI-CID-MS/MS) discrimination of the acylated monosaccharide residues with different acylation sites. A combination of ESI-CID-MS/MS, using a triple quadrupole mass spectrometer, with ultra-performance liquid chromatography (UPLC) and photo-diode array (PDA) detection (UPLC-PDA) has been applied to the identification or characterization of polyphenolic glycosides in Polygonum capitatum that possess an acylated monosaccharide residue. RESULTS An ESI-MS and CID-MS/MS method has been developed for the determination of the acylation sites of polyphenolic glycosides that possess an acylated monosaccharide residue. Twelve polyphenolic glycosides including four new ones have been identified or characterized in P. capitatum. Eight (including the new ones) of the twelve glycosides were reported for the first time from this plant. CONCLUSIONS The developed ESI-MS and CID-MS/MS method provided a very useful strategy for the determination of the sites of polyphenolic glycosides that possess an acylated monosaccharide residue. The acylation site could be determined by the characteristic product ion spectra of the in-source CID-generated O-acyl monosaccharide ion [B(1)](+). The presented work may facilitate the structural characterization of these types of compounds.

Abstract
INTRODUCTION Despite the growing interest in the use of bamboo for both food and health-related applications because it provides a rich source of anti-oxidants, there is still a lack of information on the responsible secondary metabolites of the great variety of bamboo species. OBJECTIVE To extend the knowledge on secondary metabolites of different bamboo species and to link anti-oxidant capacity with the different classes of phenolic compounds that are present in the leaves. METHODOLOGY Chromatographic profiles of 12 morphological heterogeneous bamboo species from different genera were recorded using HPLC-DAD (diode array detector) and LC-MS/MS. In addition, the in vitro anti-oxidant capacity was evaluated using a variety of anti-oxidant assays (1,1-diphenyl-2-picrylhydrazyl, Trolox-equivalent anti-oxidant capacity and oxygen radical absorbance capacity). Using partial least square (PLS) analysis as a chemometric method, the anti-oxidant capacity could be linked to specific groups of polyphenols. RESULTS Flavones and phenolic acids are the two main polyphenolic classes present in the leaf extracts of the 12 selected bamboo species. Luteolin derivatives and phenolic acids were identified as the most potent anti-oxidants. CONCLUSION The most abundant classes of phenolic compounds present in a selection of bamboo species were flavone glycosides and phenolic acids. Luteolin flavones and phenolic acids are the main anti-oxidant phenolic compounds in bamboo leaf extract. The information obtained in this study provides further support for the development of bamboo-based anti-oxidant food applications and food supplements.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herba Erigerontis injection (HEI), one of the most popular herbal prescription in China, is made from the aqueous extracts of Erigeron breviscapus whole plant. Now HEI is widely used for the treatment of cardiovascular diseases and cerebrovascular diseases such as coronary heart disease, anginapectoris and paralysis. AIM OF THE STUDY The purpose of this study was to investigate the in vivo effect of HEI on rat cytochrome P450 enzymes (CYP1A2, CYP2C11, CYP2D4, CYP2E1 and CYP3A2) to assess its safety through its potential to interact with co-administered drugs. MATERIALS AND METHODS Rats were randomly divided into five groups. Rats were intravenous administrated with HEI via the caudal vein at the dosage of 1.8ml/kg or 7.2ml/kg once daily for consecutive 3 days or 14 days. On the fourth or the fifteenth day, a cocktail solution at a dose of 5ml/kg, which contained caffeine (2.5mg/kg), tolbutamide (2.5mg/kg), chlorzoxazone (5mg/kg), midazolam (5mg/kg) and metoprolol (10mg/kg), was injected via the lingual vein to all rats. Then 0.8ml blood samples were collected at a set of time-points. The plasma concentrations of probe drugs were simultaneously determined by HPLC. Pharmacokinetic parameters simulated by DAS software were used for the evaluation of HEI on the activities of rat CYP1A2, CYP2C11, CYP2D4, CYP2E1 and CYP3A2 enzymes. ANOVA and Dunnett's test was used for data analysis. RESULTS There were no significant influence of pharmacokinetic parameters of caffeine, tolbutamide and chlorzoxazone in HEI pretreated rats. But many pharmacokinetic parameters of metoprolol and midazolam in HEI pretreated rats were affected significantly (P<0.05), which indicated that metabolism of metoprolol and midazolam in these treatment groups was evidently slowed down. CONCLUSIONS The results from the present in vivo study suggested that HEI showed no effects on rat CYP1A2, CYP2C11 and CYP2E1, however, it demonstrated potential inhibitory effects on rat CYP2D4 and CYP3A2. Therefore, caution is needed when HEI is co-administered with drugs metabolized by human CYP2D6 or CYP3A4 in clinic, which may result in increased concentrations of these drugs and relevant herb-drug interactions.

Abstract
Gemini surfactants are cationic lipids which are utilized for both in vitro and in vivo gene delivery. Structurally, they are comprised of two hydrophobic tail regions with polar head termini that are attached to one another through a spacer region. Structural elucidation and characterization of 29 novel diquaternary ammonium gemini surfactant molecules were achieved using a quadrupole time-of-flight mass spectrometer (QqToF-MS) and a quadrupole-hexapole-quadrupole mass spectrometer (QhQ-MS). The tested compounds were categorized into four distinct structural families based upon the composition of the spacer region. Single stage (MS), tandem stage (MS/MS) and quasimulti-stage (quasi MS(3)) mass spectrometric analysis allowed for confirmation of each gemini surfactant's molecular composition and structure through the identification of common and unique product ions. Identification of similarities in the gemini surfactants' fragmentation behaviour resulted in the production of a universal fragmentation pathway that can assist in the future MS/MS analysis of novel quaternary ammonium gemini surfactants, with unique product ions being indicative of specific structural elements. Furthermore, evidence for the association of agemini surfactant with bromine counter ion was confirmed during MS analysis of tested gemini surfactants regardless of their chemical composition; previously, evidence for bromine and gemini surfactant association was only observed with compounds bearing short alkyl spacer regions. MS/MS analysis of the bromine adducts was also confirmatory to the molecular structure.Understanding the ionization and fragmentation behaviour of gemini surfactants, including bromine adducts, will allow for future qualitative and quantitative identification of these novel drug delivery agents within biological samples.
