Abstract
3,4-Dicaffeoylquinic acid (3,4-DiCQA) is a dicaffeoylquinic acid that possesses antioxidant, anti-inflammatory, antibacterial, antiviral, anticancer, hypoglycemic, hypotensive, and hepatoprotective activities. This study developed a rapid and reliable method using ultra-high performance liquid chromatography equipped with linear ion trap-Orbitrap MS to identify the metabolites of 3,4-DiCQA in rat plasma, urine, feces, and tissues. The metabolic profile of 3,4-DiCQA was determined after an oral administration of 200 mg/kg to rats. A strategy of full scan-parent ions list acquisition coupled to diagnostic product ion analysis for screening and identification of target metabolites was used. A total of 67 metabolites, combined with accurate mass measurement, diagnostic ions, neutral losses, and reference standards, were observed and characterized for the first time. The results indicated that hydrolysis, methylation, hydrogenation, hydration, dehydroxylation, dehydrogenation, sulfate conjugation, and glucuronide conjugation were the major metabolic reactions of 3,4-DiCQA in vivo.

Abstract
CONTENT Isochlorogenic acid A, one of the main components of Duhaldea nervosa (Wallich ex Candolle) A. Anderberg (Asteraceae), is a folk medicine used to treat a variety of diseases including fracture and rheumatoid arthritis. Despite its widespread use, the metabolism of isochlorogenic acid A in vivo has not been fully studied. OBJECTIVE An analytical strategy based on UHPLC-Q-Exactive Orbitrap MS is proposed for the detection and identification of the metabolites of isochlorogenic acid A in rats. MATERIALS AND METHODS Six male Sprague-Dawley rats (180 ± 20 g) were randomly divided into two groups. Then, blood and tissue samples were obtained after oral administration of isochlorogenic acid A (200 mg/kg). All the samples were pre-treated by the Solid Phase Extraction (SPE) method. Next, the samples were analysed by UHPLC-Q-Exactive Orbitrap MS. Finally, the metabolites were identified based on the metabolomic workflow template. RESULTS A total of 33 metabolites were identified in rat plasma, with 30 of them being reported for the first time. The distribution of all metabolites in tissues was first investigated, three of them were widely distributed in liver, lungs, and kidneys. The corresponding reactions including methylation, hydrolysis, sulphate conjugation, glucuronide conjugation, as well as their composite reactions, are reported in this study. DISCUSSION AND CONCLUSIONS This method has wide-scale application prospects in the identification of metabolites. Considering that limited research has been conducted in this area, this study proposes metabolic pathways to further understand mechanisms of isochlorogenic acid A and the forms that are truly effective in vivo.

Abstract
In this study, we isolated nine compounds from the acid hydrolysate of the flower buds of Lonicera fulvotomentosa Hsu et S. C. Cheng and characterized their chemical structures using 1H-NMR, 13C-NMR, and electron ionization mass spectroscopy (EI-MS). These compounds were identified as β-sitosterol (1), 5,5′-dibutoxy-2,2′-bifuran (2), nonacosane-10-ol (3), ethyl (3β)-3,23-dihydroxyolean-12-en-28-oate (4), oleanolic acid (5), ethyl caffeate (6), caffeic acid (7), isovanillin (8), and hederagenin (9), with 4 as a new triterpene compound. Inhibitory activity against human immunodeficiency virus (HIV) protease was also evaluated for the compounds, and only ethyl caffeate, caffeic acid, and isovanillin (6, 7, and 8) exhibited inhibitory effects, with IC50 values of 1.0 μM, 1.5 μM, and 3.5 μM, respectively. Molecular docking with energy minimization and subsequent molecular dynamic (MD) simulation showed that ethyl caffeate and caffeic acid bound to the active site of HIV protease, while isovanillin drifted out from the active site and dissociated into bulk water during MD simulations, and most of the binding residues of HIV protease have been previously identified for HIV protease inhibitors. These results suggest that caffeic acid derivatives may possess inhibitory activities towards HIV protease other than previously reported inhibitory activities against HIV integrase, and thus ethyl caffeate and caffeic acid could be used as lead compounds in developing potential HIV protease inhibitors, and possibly even dual-function inhibitors against HIV.

Abstract
Vitiligo is a depigmentation disorder of the skin. It is primarily caused by the destruction of melanocytes or obstruction of the melanin synthesis pathway. Melanin is a type of skin pigment that determines skin color. The seeds of Vernonia anthelmintica (L.) Willd (Kaliziri) are used for treating skin diseases including vitiligo in traditional Uyghur medicine. 1,5‑Dicaffeoylquinic acid (1,5‑diCQA) is a natural polyphenolic compound widely distributed in plants and extracted from Kaliziri seeds. Therefore, in the present study, the effect of 1,5‑diCQA on melanin synthesis in B16 cell was evaluated, and its molecular mechanism was explored. The results indicated that 1,5‑diCQA treatment of B16 cells stimulated an increase of intracellular melanin level and tyrosinase (TYR) activity without cytotoxicity. Reverse transcription quantitative polymerase chain reaction results also indicated that 1,5‑diCQA may markedly improve the protein expression and RNA transcription of microphthalmia‑associated transcription factor (MITF), melanogenic enzyme Tyr, tyrosinase‑related protein 1 (TRP 1) and tyrosinase‑related protein 2 (TRP 2). Additional results identified that 1,5‑diCQA may promote the phosphorylation of p38 mitogen‑activated protein kinase (p38 MAPK) and extracellular signal‑regulated kinase (ERK) MAPK. Notably, the increased levels of intracellular melanin synthesis and tyrosinase expression induced by 1,5‑diCQA treatment were significantly attenuated by the protein kinase A (PKA) inhibitor H‑89. Intracellular cyclic adenosine monophosphate (cAMP) concentration and phosphorylation of cAMP‑response element binding protein was increased following 1,5‑diCQA treatment. These results indicated that 1,5‑diCQA stimulated melanogenesis via the MAPK and cAMP/PKA signaling pathways in B16 cells, which has potential therapeutic implications for vitiligo.

Ha JH, Park SN. Mechanism underlying inhibitory effect of six dicaffeoylquinic acid isomers on melanogenesis and the computational molecular modeling studies. Bioorg Med Chem 2018; 26:4201-4208. [PMID: 30030001 DOI: 10.1016/j.bmc.2018.07.014] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2018] [Revised: 07/01/2018] [Accepted: 07/07/2018] [Indexed: 12/27/2022]
Abstract
Dicaffeoylquinic acid (DCQA), which contain 2 caffeic acids and a quinic acid, is 6 isomeric compounds (1,3-, 1,4-, 1,5-, 3,4-, 3,5-, and 4,5-DCQA). In this study, the mechanism underlying the inhibitory effect of DCQA isomers on melanogenesis in B16F1 murine melanoma cells stimulated by melanocyte stimulating hormone (α-MSH) was evaluated. DCQA isomers showed inhibitory effects on melanogenesis in α-MSH-stimulated B16F1 cells. Furthermore, the anti-melanogenesis activities of 1,5-DCQA and 4,5-DCQA were 61% and 84%, respectively, which were greater than that of arbutin (35%). For cell-free tyrosinase, 3,4-DCQA and 4,5-DCQA indicated high inhibitory effects, similar to the activity to arbutin (35%) at 25 μM. DCQA isomers inhibited the melanogenic enzymes including tyrosinase and dopachrome tautomerase (DCT) on α-MSH-stimulated B16F1 cells. Interestingly, 4,5-DCQA, the most potent inhibitor of melanogenesis among the six DCQA isomers, significantly downregulated the expression of microphthalmia-associated transcription factor (MITF), tyrosinase-related protein 1 (TRP1) containing tyrosinase, and DCT. In particular, the inhibitory mechanism of 4,5-DCQA on MITF expression was elucidated, revealing that 4,5-DCQA inhibits the phosphorylation of cAMP response element-binding protein (CREB) by attenuating cAMP generation during melanogenesis. A molecular docking study was conducted to elucidate the inhibitory mechanism of 4,5-DCQA on cAMP production. DCQA isomers dock to the residues of adenylyl cyclase with a distance of <3 Å, except for 1,3-DCQA. Especially, 4,5-DCQA showed Full Fitness of -1304.68 kcal/mol and △G of -8.33 kcal/mol, as well as H-bonding with adenylyl cyclase at ILE953 and LYS930 residues. In conclusion, DCQA isomers have different effects on melanogenesis depending on their structure. Especially, 4,5-DCQA has depigmentation activity through the inhibitory effect on cellular tyrosinase directly and binding effect on adenylyl cyclase, resulting in the downregulation of MITF protein, thereby reducing the expression of melanogenic enzymes.

Abstract
BACKGROUND This study aimed to concentrate dietary fiber (DF) from peach (Prunus persica) juice by-product (PJBP), to improve its functional properties, and its polyphenols bioavailability. The dietary fiber concentrates (DFCs) were obtained from PJBP using water/ethanol treatments (100:0, 20:80, 50:50, 80:20, and 0:100, v/v) at 1:5 ratio (wet weight/solvent, w/v) for 5 and 20 min at 21 °C. RESULTS All treatments concentrated condensed tannins, total and insoluble DF, with the highest content found with 100% H2 O treatment. The major polyphenols of DFC were 4-O-caffeoylquinic, chlorogenic, and 1,5-di-O-caffeoylquinic acids. Water and oil retention capacity and maximum glucose diffusion rate were improved mainly with 100% H2 O treatment. Healthy rats were fed with a standard diet supplemented with 8% of PJBP, DFC obtained with 100% H2 O for 5 min, or DFC obtained with 20% EtOH for 5 min. Gastrointestinal digesta weight and viscosity were increased in animals supplemented with 100% H2 O DFC. Moreover, the urinary excretion of polyphenol metabolites, mainly glucuronide and sulfate conjugates, was increased with this treatment, indicating a greater bioavailability of PJBP polyphenols, which was associated with an increased dietary fiber porosity. CONCLUSION Water treatment could be used to potentiate PJBP functional properties and polyphenols bioavailability. © 2017 Society of Chemical Industry.

Abstract
Methyl 3,5-di-caffeoylquinate (3,5-diCQM) has been used for the treatment of various diseases in oriental medicine, but its effect on melanogenesis has not been reported yet. In this study, the molecular mechanism of 3,5-diCQM-induced melanogenesis was investigated. It was found that 3,5-diCQM induced synthesis of melanin pigments in murine B16F10 melanoma cells in a concentration-dependent manner. Treatment of cells with 3,5-diCQM for 48 h increased extracellular and intracellular melanin production and tyrosinase activity. The expressions of tyrosinase, tyrosinase-related protein 1 (TRP1), and TRP2 were up-regulated in a dose-dependent manner 48 h after 3,5-diCQM treatment. Western blot analysis showed that 3,5-diCQM increased the phosphorylation of p38 mitogen-activated protein kinase and cAMP responsive element binding as well as the expression of microphthalmia-associated transcription factor. In addition, 3,5-diCQM-stimulated cAMP production, and 3,5-diCQM-induced tyrosinase activity and melanin synthesis were attenuated by H89, a protein kinase A inhibitor. These results suggested that 3,5-diCQM-mediated activation of the p38 pathway may represent a novel approach for an effective therapy for vitiligo and hair graying.

Abstract
The anti-bacterial activities of three types of di-O-caffeoylquinic acids (diCQAs) in Lonicera japonica flowers, a traditional Chinese medicine (TCM), on Bacillus shigae growth were investigated and compared by microcalorimetry. The three types of diCQAs were 3, 4-di-O-caffeoylquinic acid (3, 4-diCQA), 3, 5-di-O-caffeoylquinic acid (3, 5-diCQA), and 4, 5-di-O-caffeoylquinic acid (4, 5-diCQA). Some qualitative and quantitative information of the effects of the three diCQAs on metabolic power-time curves, growth rate constant k, maximum heat-output power Pm, and the generation time tG, total heat output Qt, and growth inhibitory ratio I of B. shigae were calculated. In accordance with a thermo-kinetic model, the corresponding quantitative relationships of k, Pm, Qt, I and c were established. Also, the half-inhibitory concentrations of the drugs (IC50) were obtained by quantitative analysis. Based on the quantity-activity relationships and the IC50 values, the sequence of inhibitory activity was 3, 5-diCQA > 4, 5-diCQA > 3, 4-diCQA. The results illustrate the possibility that the caffeoyl ester group at C-5 is the principal group that has a higher affinity for the bacterial cell, and that the intramolecular distance of the two caffeoyl ester groups also has an important influence on the anti-bacterial activities of the diCQAs.

[PMID: 24754913 DOI: 10.1016/j.jep.2014.04.010] [Citation(s) in RCA: 119] [Impact Index Per Article: 11.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/27/2013] [Revised: 04/03/2014] [Accepted: 04/05/2014] [Indexed: 05/28/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE The genus Inula comprises more than one hundred species widespread in temperate regions of Europe and Asia. Uses of this genus as herbal medicines have been first recorded by the Greek and Roman ancient physicians. In the Chinese Pharmacopoeia, from the 20 Inula spp. distributed in China, three are used as Traditional Chinese medicines, named Tumuxiang, Xuanfuhua and Jinfeicao. These medicines are used as expectorants, antitussives, diaphoretics, antiemetics, and bactericides. Moreover, Inula helenium L. which is mentioned in Minoan, Mycenaean, Egyptian/Assyrian pharmacotherapy and Chilandar Medical Codex, is good to treat neoplasm, wound, freckles and dandruff. Many other Inula spp. are used in Ayurvedic and Tibetan traditional medicinal systems for the treatment of diseases such as bronchitis, diabetes, fever, hypertension and several types of inflammation. This review is a critical evaluation of the published data on the more relevant ethnopharmacological and medicinal uses of Inula spp. and on their metabolites biological activities. This study allows the identification of the ethnopharmacological knowledge of this genus and will provide insight into the emerging pharmacological applications of Inula spp. facilitating the prioritirization of future investigations. The corroboration of the ethnopharmacological applications described in the literature with proved biological activities of Inula spp. secondary metabolites will also be explored. MATERIALS AND METHODS The major scientific databases including ScienceDirect, Medline, Scopus and Web of Science were queried for information on the genus Inula using various keyword combinations, more than 180 papers and patents related to the genus Inula were consulted. The International Plant Name Index was also used to confirm the species names. RESULTS Although the benefits of Inula spp. are known for centuries, there are insufficient scientific studies to certify it. Most of the patents are registered by Chinese researchers, proving the traditional use of these plants in their country. Although a total of sixteen Inula species were reported in the literature to have ethnopharmacological applications, the species Inula cappa (Buch.-Ham. ex D.Don) DC., Inula racemosa Hook.f., Inula viscosa (L.) Aiton [actually the accepted name is Dittrichia viscosa (L.) Greuter], Inula helenium, Inula britannica L. and Inula japonica Thunb. are the most frequently cited ones since their ethnopharmacological applications are vast. They are used to treat a large spectrum of disorders, mainly respiratory, digestive, inflammatory, dermatological, cancer and microbial diseases. Fifteen Inula spp. crude extracts were investigated and showed interesting biological activities. From these, only 7 involved extracts of the reported spp. used in traditional medicine and 6 of these were studied to isolate the bioactive compounds. Furthermore, 90 bioactive compounds were isolated from 16 Inula spp. The characteristic compounds of the genus, sesquiterpene lactones, are involved in a network of biological effects, and in consequence, the majority of the experimental studies are focused on these products, especially on their cytotoxic and anti-inflammatory activities. The review shows the chemical composition of the genus Inula and presents the pharmacological effects proved by in vitro and in vivo experiments, namely the cytotoxic, anti-inflammatory (with focus on nitric oxide, arachidonic acid and NF-κB pathways), antimicrobial, antidiabetic and insecticidal activities. CONCLUSIONS Although there are ca. 100 species in the genus Inula, only a few species have been investigated so far. Eight of the sixteen Inula spp. with ethnopharmacological application had been subjected to biological evaluations and/or phytochemical studies. Despite Inula royleana DC. and Inula obtusifolia A. Kerner are being used in traditional medicine, as far as we are aware, these species were not subjected to phytochemical or pharmacological studies. The biological activities exhibited by the compounds isolated from Inula spp., mainly anti-inflammatory and cytotoxic, support some of the described ethnopharmacological applications. Sesquiterpene lactone derivatives were identified as the most studied class, being britannilactone derivatives the most active ones and present high potential as anti-inflammatory drugs, although, their pharmacological effects, dose-response relationship and toxicological investigations to assess potential for acute or chronic adverse effects should be further investigated. The experimental results are promising, but the precise mechanism of action, the compound or extract toxicity, and the dose to be administrated for an optimal effect need to be investigated. Also human trials (some preclinical studies proved to be remarkable) should be further investigated. The genus Inula comprises species useful not only in medicine but also in other domains which makes it a high value-added plant.

An integrated strategy based on UPLC-DAD-QTOF-MS for metabolism and pharmacokinetic studies of herbal medicines: Tibetan "Snow Lotus" herb (Saussurea laniceps), a case study. JOURNAL OF ETHNOPHARMACOLOGY 2014; 153:701-13. [PMID: 24661968 DOI: 10.1016/j.jep.2014.03.031] [Citation(s) in RCA: 30] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/04/2013] [Revised: 02/22/2014] [Accepted: 03/13/2014] [Indexed: 05/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Saussurea laniceps Hand.-Mazz. (SL) has long been used under the herbal name Tibetan "Snow Lotus" for the treatment of rheumatoid arthritis, stomachache and dysmenorrhea in Tibetan folk medicine. Since herbal medicine (HM) is a synergistical system with multiple components, both of the metabolism and pharmacokinetic studies of HM are interdependent. This study aimed to develop an integrated strategy based on the UPLC-DAD-QTOF-MS technique for metabolism and pharmacokinetic studies of HM. MATERIAL AND METHODS SL was used here as a test herb to verify the feasibility of the proposed strategy. SL was administered to rats, then, the blood plasma, urine and feces were analyzed to determine the metabolic profiles. Using our strategy, umbelliferone and scopoletin were evaluated to be the key bioactive components. Their pharmacokinetic parameters were measured and biotransformation pathways were elucidated. RESULTS After oral administration of SL to rats, 17 components in blood, 10 components in urine and 2 components in feces were identified and characterized using our UPLC-DAD-QTOF-MS method. Umbelliferone, scopoletin and their metabolites were found to be the major components involved in the metabolism process. Literature reports also suggest that umbelliferone and scopoletin are responsible for the therapeutic effects of SL, thus these two components were selected as the active markers for pharmacokinetic study. In the test of validity, the established method presented good linearity with R(2)>0.99. The relative standard deviation value was below 13.9% for precision, and recovery studies for accuracy were found to be within the range 91.8-112.5%. CONCLUSION The present strategy offers, simultaneously, precision in quantitative analysis (metabolism study) and accuracy in quantitative analysis (pharmacokinetic study) with greater efficiency and less costs, which is therefore reliably used for integrated metabolism and pharmacokinetic studies of HM.

Abstract
β-Lapachone (3,4-dihydro-2,2-dimethyl-2H-naphthol[1,2-b]pyran-5,6-dione) is a natural compound extracted from the bark of the lapacho tree (Tabebuia avellanedae) and is undergoing phase II clinical trials as an antitumor drug candidate. The present study characterized in vitro metabolites of β-lapachone in mouse, rat, dog, monkey and human liver microsomes. β-Lapachone (10 μM) was incubated with mouse, rat, dog, monkey, and human liver microsomes in the presence of NADPH. The reaction mixtures were analyzed by LC/MS and the metabolites were identified based on their elemental composition and product ion spectra. A total of 6 metabolites (M1-M6) were detected in liver microsomes with a slight difference between species. M1 and M6 were identified as a decarbonated metabolite and a carboxylated metabolite, respectively; M2, M3, and M4 were identified as monohydroxylated metabolites; and M5 was identified as an O-methylated metabolite. M5, an O-methylated metabolite was found in rat and human liver microsomes, which is thought to be formed from a catechol intermediate by MB-COMT-mediated methylation and reported here for the first time.

Abstract
OBJECTIVE Comparison of the effects of a high-fructose diet supplemented with rutin, a phenolic compound with well-recognized bioavailability and bioactivity, and a chicory (Cichorium intybus L.) seed extract rich in caffeoylquinic acids (CQA) on gut physiology and the development of disorders related to metabolic syndrome. METHODS A 28-d experiment was conducted on 32 young male Wistar rats. In comparison with control rats fed a standard corn starch diet (group C), the experimental group (group E) was fed a diet with an increased content of cholesterol and fructose (to 1% and 66% of the diet, respectively), as well as with oxidized soybean oil. Rats from the other two experimental groups were administered the same diet as group E during the first 2 wk of feeding, whereas at the beginning of the last 2 wk, the diet was enriched with rutin (group ER) or the CQA-rich ethanol extract from chicory seeds (9.6% of CQA, group EC), so the amount of added phenolics was equal in both dietary groups (0.15%). RESULTS The diet administered in group E caused hyperglycemia and increased blood serum atherogenicity in rats, but did not induce other manifestations of the metabolic syndrome, i.e., dyslipidemia and oxidative stress. Additionally, it affected gut physiology through increasing mucosal sucrase activity and disturbing fermentative processes in the cecum, such as the production of short-chain fatty acids and the activity of microbial enzymes. Similarly to rutin, the dietary addition of the chicory seed extract improved glycemia, which was comparable to that determined in group C. In addition, the extract was found to decrease the atherogenic index to the level observed in group C and to increase blood antioxidant status. Both dietary supplements reduced the content of thiobarbituric acid-reactive substances in kidney and heart tissue when compared with group E. CONCLUSION The potential efficacy of the CQA-rich extract from chicory seeds in improving diet-induced metabolic disturbances proved to be better than that of rutin; thus, the extract might be considered as a dietary supplement for carrying out clinical trials.

Abstract
Feruloylquinic acids are a major class of biologically active phenolic antioxidants in coffee beans, but their metabolic fate is poorly understood. The present study investigated the phase II metabolism of feruloylquinic acids with selected human sulfotransferases (SULT1A1 and SULT1E1) and uridine 5'-diphosphoglucuronosyltransferases (UGT1A1 and UGT1A9). For unequivocal metabolite identification, the chemical synthesis of two potential human metabolites of 5-O-feruloylquinic acid, the 4'-sulfated and 4'-O-glucuronidated conjugates, has been performed for the first time. Following incubation with human SULT1A1 or SULT1E1, formation of 5-O-feruloylquinic acid 4'-O-sulfate was confirmed by matching its HPLC and MS data with those of the authentic standard. On the other hand, no glucuronide conjugates were detected after incubation with human uridine 5'-diphosphoglucuronosyltransferases. These results suggest that sulfation can take place on the ferulic acid moiety of feruloylquinic acids and may be a major metabolic pathway for feruloylquinic acids in humans.

Abstract
Snow lotus is commonly used as a medicinal plant and has great pharmacological value. To protect these endangered plants, in vitro propagation and cell cultures have been established in order to meet the growing market demand. The phenolic composition, antioxidant activities, total phenolic content (TPC) and total flavonoid content (TFC) from three most commonly used species, in vitro propagated lines and the cell cultures were investigated to qualify their pharmacological value. Quantitative analysis showed that the phenolics varied greatly among different species and the same species at different habitats. From this it can be inferred that the phenolics were influenced by genetic background and the environmental conditions. Significant correlations were observed between the antioxidant activity and several phenolics/TPC/TFC, suggesting that the phenolics are a major contributor of the antioxidant activity and are important for quality evaluation of snow lotus. Based on the abundance of phenolics, TPC, TFC and antioxidant activity, the order of the quality for wild species would be Saussurea involucrata > Saussurea medusa > Saussurea gossypiphora. For S. medusa, its quality judged by origin would be Shigatse > Lhasa > Nagqu. For in vitro propagated plants, the matured plants could be a reliable substitute for wild plants, and the dynamics of phenolics is critical for quality control of this monocarpic species. We provide the first report of quality comparison between the wild plants and the cell cultures. The advantages of developing cell cultures as alternatives for plants collected from the wild are discussed.

Abstract
In this study, a sensitive, selective and reproducible liquid chromatography-tandem mass spectrometry method for the simultaneous determination of 1,5-dicaffeoylquinic acid (1,5-DCQA) and its active metabolites, 1-caffeoyl-5-feruoylquinic acid and 1,5-O-diferuoylquinic acid, in human plasma, using puerarin as internal standard, was developed and validated. Analytes were extracted from plasma samples by liquid-liquid extraction with ethyl acetate, separated on a C(18) reversed-phase column with water containing 5 mM ammonium acetate and acetonitrile as the mobile phase and detected by electrospray ionization mass spectrometry in negative selected reaction monitoring mode. The accuracy and precision of the method were acceptable and linearity was good over the range 1-200 ng/mL for each analyte. In addition, the selectivity, extraction recovery and matrix effect were satisfactory too. The validated LC-MS/MS method was successfully applied to phase II clinical pharmacokinetic study of 1,5-DCQA in patients.

Abstract
All four regioisomers of feruloyl quinic acid and isoferuloyl quinic acid were synthesized and a liquid chromatography/tandem mass spectrometry (LC/MS/MS) method developed that resolves all eight regioisomers. All eight regioisomers can be readily distinguished by their MS/MS spectra in the negative ion mode, illustrating the power of tandem mass spectrometry to elucidate the structures of regioisomeric compounds. Compound identification is possible, either by direct comparison of spectral fingerprints or by rational probing of diagnostic fragment ions, thus allowing the identification of these important classes of natural products and potential human metabolites.

Abstract
Five caffeoylquinic acid derivatives (CQAs), including methyl 3,4-di-O-caffeoylquinate (3,4-diCQM), methyl 3,5-di-O-caffeoylquinate (3,5-diCQM), 3,4-di-O-caffeoylquinic acid (3,4-diCQA), 3,5-di-O-caffeoylquinic acid (3,5-diCQA) and chlorogenic acid (CA), were isolated from Lonicera fulvotomentosa HSU et S. C. CHENG to be used as model compounds. The binding of these bioactive components to bovine serum albumin (BSA) was investigated by fluorescence quenching method. The results showed that there were binding affinities for CQAs with BSA, and the binding constants ranked in the following order: 3,4-diCQM>3,5-diCQM<3,4-diCQA>3,5-diCQA>CA, under the physiological conditions, which suggested that the numbers and the substituted positions of caffeoyl group as well as the esterification of carboxyl group in the molecular structures appeared to contribute moderate effects to the interaction processes. Furthermore, the Stern-Volmer curves demonstrated that CQAs caused the fluorescence quenching through a static quenching procedure. Thermodynamic analysis indicated that both hydrophobic and electrostatic interactions played major roles in stabilizing the complex. The binding distance for each binding reaction was also calculated by the Föster theory.

Abstract
Curcuminoids are a safe natural food coloring additive with anti-inflammatory, antioxidant, and anticarcinogenic activities. Although demethoxycurcumin is one of the major bioactive constituents of curcuminoids, knowledge about its metabolic fate is scant. In the present study, four new metabolites, 5-dehydroxy-hexahydro-demethoxycurcumin-A (M-1), 5-dehydroxy-hexahydro-demethoxycurcumin-B (M-2), 5-dehydroxy-octahydro-demethoxy-curcumin-A (M-3) and 5-dehydroxy-octahydro-demethoxycurcumin-B (M-4), were isolated from feces of male Wistar-derived rats and from urine; three new metabolites, 5-O-methyl-hexahydrodemethoxycurcumin-A (M-7), 5-O-methyl-hexahydro-demethoxycurcumin-B (M-8), and 5-dehydroxy-dihydro-demethoxycurcumin-B (M-9), and two known metabolites, hexahydro-demethoxycurcumin-A (M-5) and hexahydro-demethoxycurcumin-B (M-6), were isolated. Their structures were established by chemical and spectral methods. ll of them were reductive metabolites. Possibly of greater importance is that they occurred as pairs of isomers with a methoxyl group substituted on a different benzene ring. This finding in the metabolism of curcuminoids is reported here for the first time. In addition, the 5-dehydroxy or 5-O-methylated metabolites are also a novel finding. The fact that the metabolites occurred as pairs of the isomers suggests that demethoxycurcumin possibly undergoes tautomerization between 3-keto-5-enol (form A) and 3-keto-5-enol (form B) in rats. Based on the metabolite profiles, metabolic pathways of demethoxycurcumin in rats are proposed.

Abstract
1,5-Dicaffeoylquinic acid (1,5-DCQA), a potent HIV-1 integrase inhibitor, is undergoing an evaluation as a promising novel HIV therapeutic agent. Here, we report a simple, rapid and robust LC-MS/MS method for simultaneous determination of 1,5-DCQA and its two active metabolites, 1-caffeoyl-5-feruoylquinic acid (1,5-CFQA) and 1,5-O-diferuoylquinic acid (1,5-DFQA) in human plasma. The quantitation of the target compounds was determined by selected reaction monitoring (SRM) mode using electrospray ionization (ESI). Good linearity was obtained in the 3-500 ng/ml range for each analyte and the analytical method was validated in terms of specificity, precision, accuracy, recovery, stability and matrix effect. These assays gave R.S.D.% values for precision always lower than 13.8% and R.E.% values for accuracy between -8.9 and 0.9%. In addition, the specificity, extraction recovery, stability and matrix effect were satisfactory too. Using the measured plasma concentrations of 1,5-DCQA and its active metabolites in five healthy volunteers, pharmacokinetic profiles of 1,5-DCQA and its active metabolites were evaluated, which supported the clinical pharmacokinetic studies successfully. Due to its high sensitivity, specificity and simplicity, the method could be used for pharmacokinetic studies of both 1,5-DCQA and its active metabolite, and for routine monitoring of their levels in human plasma.

[PMID: 16143483 DOI: 10.1016/j.jpba.2005.06.037] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2005] [Revised: 06/06/2005] [Accepted: 06/15/2005] [Indexed: 11/19/2022]
Abstract
1,5-Dicaffeoylquinic acid (1,5-DCQA) is a potentially important HIV-1 integrase inhibitor widely distributed in many plants. To characterize the pharmacokinetic and metabolic properties of 1,5-DCQA in rats following single intravenous administration (160 mg/kg), the plasma concentrations of 1,5-DCQA were measured by high-performance liquid chromatography (HPLC) and the metabolites formed in urine were identified by liquid chromatography-mass spectrometry (LC-MS) in parallel to diode-array detection (DAD). The results showed that the concentrations of 1,5-DCQA in plasma declined rapidly in a biphasic manner with a mean terminal half-life (t(1/2)) of 1.40 h. The mean clearance (CL) and the apparent volume of distribution (Vd(B)) of 1,5-DCQA were 0.44l/h/kg and 0.89l/kg, respectively. A total of 15 metabolites in rat urine were identified, including four isomeric O-mono-methylated (M1-M4), six isomeric O-di-methylated (M5-M10), one isomeric O-mono-methyl-glucuronidated (M11) and four isomeric O-di-methyl-glucuronidated (M12-M15) metabolites. The O-methylation positions of three important metabolites (M1, M2 and M5) were determined (3''-, 3'-, and 3',3''-) by comparing with synthesized standards. These results suggested that the disappearance of 1,5-DCQA from plasma was rapid, and that its quick urinary excretion and extensive metabolism, including methylation and glucuronidation, were two factors causing its rapid elimination from the circulation.
