Abstract
Daurisoline, a bisbenzylisoquinoline alkaloid extracted from the rhizomes of Menispermum dauricum, exhibits diverse biological activities, encompassing antiplatelet, anti-inflammatory, neuroprotective, and antitumor properties. However, previous investigations have not comprehensively elucidated the metabolic profile and pathways of daurisoline in vivo. Using Ultra-High-Performance Liquid Chromatography with Q-Exactive Orbitrap Mass Spectrometry technology, we comprehensively investigated the metabolites of daurisoline in Sprague-Dawley rats, following intragastric administration. Data collection and analysis were enhanced through Full Scan MS/dd-MS2, in conjunction with parallel reaction monitoring, extracted ion chromatography, and diagnostic fragment ions. Sixty-three metabolites were detected and characterized, including sixty-two novel metabolites and coclaurine. This investigation elucidated the cleavage patterns and tissue distribution characteristics of the metabolism of daurisoline. Furthermore, in vivo reactions, including dehydrogenation, hydroxylation, methylation, sulfation and glucuronidation, were thoroughly examined. Investigating the metabolites of daurisoline in rats has deepened our understanding of its metabolism in vivo, aiding in elucidating its metabolic and pharmacological actions. This provides a valuable foundation for further research into its therapeutic efficacy.

[PMID: 38845878 PMCID: PMC11153250 DOI: 10.1016/j.heliyon.2024.e31909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 05/22/2024] [Accepted: 05/23/2024] [Indexed: 06/09/2024] Open
Abstract
Psoriasis is an inflammation-based skin illness marked by aggravated proliferation of epidermal cells. Shikonin is a natural naphthoquinone obtained from Arnebiae radix. It exerts anti-inflammatory and immunosuppressive effects. However, the poor water solubility and low bioavailability of shikonin limit its application. In this study, shikosin-loaded PLGA nanoparticle hydrogel was prepared and used to deliver the drug to the epidermis of psoriasis mice through local administration. The results demonstrated that shikosin-loaded PLGA nanoparticles inhibited HaCaT cell multiplication, increased drug uptake, and induced apoptosis of HaCaT cells. Results from Western blotting assays indicated that shikosin down-regulated the protein expressions of p65 and p-p65. Furthermore, shikonin mitigated psoriasis and decreased the concentrations of inflammation-inducing cytokines, i.e., IL17A, IL-17F, IL-22, IL-1β, and TNF-α. Taken together, these results suggest that shikonin-PLGA nanoparticles loaded in hydrogel system possess promising therapeutic potential for psoriasis.

Abstract
This investigation aimed to identify the most favorable cultivar based on plant metabolites for potential targeted cultivation in the pharmaceutical industry. The analysis revealed the presence of 19 individual phenolics and 80 individual volatiles across the cultivars, a breadth of data not previously explored to such an extent. Flavones emerged as the predominant phenolic group in all mint-scented cultivars, except for peppermint, where hydroxycinnamic acids dominated. Peppermint exhibited high concentrations of phenolic acids, particularly caffeic acid derivatives and rosmarinic acid, which are known for their anti-inflammatory and antioxidant properties. Luteolin-rich concentrations were found in several mint varieties, known for their antioxidative, antitumor, and cardio-protective properties. Swiss mint and spearmint stood out with elevated levels of flavanones, particularly eriocitrin, akin to citrus fruits. Monoterpene volatiles, including menthol, camphor, limonene, and carvone, were identified across all cultivars, with Swiss mint and spearmint exhibiting the highest amounts. The study underscores the potential for targeted cultivation to enhance volatile yields and reduce agricultural land use. Notably, chocolate mint demonstrated promise for volatile content, while apple mint excelled in phenolics, suggesting their potential for broader agricultural, pharmaceutical, and food industry production.

Abstract
Arnebiae Radix, commonly known as "Zicao," can be easily confused with other compounding species, posing challenges for its clinical use. Here, we developed a comprehensive strategy to systematically characterize the diverse components across Arnebiae Radix and its three confusing species. First, an offline two-dimensional liquid chromatography (2D-LC) system integrating hydrophilic interaction chromatography (HILIC) and reverse phase (RP) separations was established, enabling effective separation and detection of more trace constituents. Second, a polygonal mass defect filtering (MDF) workflow was implemented to screen target ions and generate a precursor ion list (PIL) to guide multistage mass (MSn) data acquisition. Third, a three-step characterization strategy utilizing diagnostic ions and neutral losses was developed for rapid determination of molecular formulas, structure classes, and compound identification. This approach enabled systematic characterization of Arnebiae Radix and its three confusing species, with 437 components characterized including 112 shikonins, 22 shikonfurans, 144 phenolic acids, 131 glycosides, 18 flavonoids, and 10 other compounds. Additionally, 361, 230, 340, and 328 components were identified from RZC, YZC, DZC, and ZZC, respectively, with 142 common components and 30 characteristic components that may serve as potential markers for distinguishing the four species. In summary, this is the first comprehensive characterization and comparison of the phytochemical profiles of Arnebiae Radix and its three confusing species, advancing our understanding of this herbal medicine for quality control.

Abstract
Sideritis scardica Griseb, also known as "mountain tea" and "Olympus tea" (Lamiaceae family) is an endemic plant from the mountainous regions of the Balkan Peninsula. In this study, we focused on an in-depth phytochemical analysis of S. scardica infusion using ultra-high-performance liquid chromatography hyphenated with high-resolution mass spectrometry (UHPLC-HRMS). Quantitative determination of the main secondary metabolites was carried out by UHPLC-HRMS analyses using the external standard method. The results revealed more than 100 metabolites, including five sugar acids and saccharides, 21 carboxylic, hydroxybenzoic, hydroxycinnamic acids, and derivatives, 15 acylquinic acids, 10 phenylpropanoid glycosides, four iridoid glycosides, 28 flavonoids, seven fatty acids, and four organosulfur compounds. Furthermore, a dereplication and fragmentation patterns of five caffeic acids oligomers and four acylhexaric acids was performed for the first time in S. scardica. Regarding the quantitative analysis, the phenylethanoid verbascoside (53) (151.54 ± 10.86 mg/g lyophilized infusion, li), the glycosides of isoscutellarein (78) (151.70 ± 14.78 mg/g li), methylisoscutelarein (82) (107.4 ± 9.07 mg/g li), and hypolaetin (79) (78.33 ± 3.29 mg/g li), as well as caffeic acid (20) (87.25 ± 6.54 mg/g li), were found to be the major compounds in S. scardica infusion. The performed state-of-the-art phytochemical analysis of S. scardica provides additional knowledge for the chemical constituents and usage of this valuable medicinal plant.

Abstract
Traditional Chinese medicine has been used to treat diabetic foot ulcer (DFU) for a long time. However, the underlying mechanism of Radix arnebiae seu lithospermi ointment (RAS-ointment) has not been revealed. Effects of RAS-ointment treatment were observed in DFU patients. The endogenous competitive RNA mechanism was constructed based on micro-array sequencing and bioinformatics analysis. RT-PCR was used to detected the expression of genes in DFU ulcerated skins and non-ulcerated skins. Dual luciferase and RT-PCR experiments were used to investigate the endogenous competitive RNA mechanism. Based on micro-array sequencing and bioinformatics analysis, we found that SNHG12/NFYC-AS1, hsa-miR-199a-5p and S100A8/S100A7/XDH might form an endogenous competitive RNA mechanism. RT-PCR assay shown that SNHG12, NFYC-AS1, S100A8, S100A7 and XDH were significantly up-regulated, while hsa-miR-199a-5p was significantly down-regulated in DFU ulcerated skins (N = 10) compared with non-ulcerated skins (N = 10). Dual luciferase and RT-PCR experiments showed that SNHG12 or NFYC-AS1 up-regulated the expression of S100A8, S100A7 and XDH by inhibiting hsa-miR-199a-5p in a direct binding way. After 35 days of RAS-ointment treatment, the wound healing of DFU patients was substantially improved and the expression of S100A7 and XDH were reduced expression in DFU patients. In addition, the monomer composition of RAS-ointment, 49070_FLUKA or auraptenol inhibited the expression of S100A7 and XDH in Te317.sk cells. In conclusion, RAS-ointment may be used as an adjunctive therapy for DFU patients.

Abstract
The application of metabolomics to the study of plants is growing because of the current development of analytical techniques. The most commonly used analytical technology driving plant metabolomics studies is Mass Spectrometry (MS) coupled to liquid chromatography (LC). In recent years, Nuclear Magnetic Resonance (NMR) spectroscopy, not requiring a previous chromatographic separation, has been receiving growing attention for metabolite fingerprinting of natural extracts. Herein, an integrated LC-MS and 1H NMR metabolomic approach provided a comprehensive phytochemical characterization of Symphytum anatolicum whole plant, taking into account both primary and specialized metabolites. Moreover, the NMR analyses provided direct quantitative information. Species belonging to the Symphytum genus, known as comfrey, have shown several biological activities including anti-inflammatory, analgesic, hepatoprotective, antifungal, and antibacterial. The LC-MS profile showed the presence of 21 main specialized metabolites, belonging to the classes of flavonoids, phenylpropanoids, salvianols, and oxylipins. The 1H NMR spectrum revealed the occurrence of metabolites including organic acids, phenolics, flavonoids, sugars, and amino acids. A quantitative analysis of these metabolites was performed and their concentration was obtained with respect to the known concentration of TSP, by means of the software package Chenomx which allows quantification of individual components in the NMR spectra. Furthermore, the phenolic content, antioxidant activity, glucosidase, and tyrosinase inhibitory activity of S. anatolicum extract were evaluated. The resulting bioactivity profile suggests how S. anatolicum represents a source of metabolites with health-promoting activity.

Abstract
Diacerein, a competently semisynthetic diacetyl derivative of anthraquinone, is a nonsteroidal anti-inflammatory drug, which has been used for treating osteoarthritis and preventing vascular diseases. However, previous investigation indicated that diacerein metabolites and its metabolic pathway in vivo was still unclear. In this research, an effective method was established based on ultra-high-performance liquid chromatography coupled with Q-Exactive-Orbitrap mass spectrometer and molecular docking to screen and detect the potential active metabolites of diacerein in rat plasma after oral administration. The data acquisition and processing methods including Full MS-ddMS2 combined with parallel reaction monitoring mode, extracted ion chromatogram and diagnostic fragment ions were adopted to detect and identify more infinitesimal and unknown diacerein metabolites in vivo. As a result, a total of 32 metabolites were detected and identified in rat plasma according to retention times, accurate mass, diagnostic fragment ions, and relevant drug biotransformation knowledge, among 31 metabolites were firstly reported in this study. Then, the relevant reactions in vivo such as deacetylation, hydroxylation, methylation, sulfate conjugation, glucuronidation, and their composite reactions, were all detected. Ultimately, the results of molecular docking showed that the metabolites of diacerein might have good affinity with IL-1 receptor in vivo. Among them, the metabolites M21 and M1 have the strongest binding affinity with IL-1 receptors, and could be considered as potential active metabolites of diacerein, which have an efficient effect on exerting pharmacological effects of diacerein in vivo. In conclusion, the study of diacerein metabolites in rat plasma expanded our understanding about the metabolism of diacerein in vivo and provided the significant foundation for further drug efficacy studies.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE As a traditional Chinese medicine formula, Jingxin Zhidong Formula (JXZDF) based on ancient amber powder has been prescribed to alleviate tic disorders (TD) according to our clinical practice for many years. However, the underlying molecular mechanisms remain largely unknown. AIM OF STUDY To explore the potential mechanism of JXZDF in the treatment of TD by using network pharmacology and experimental validation. MATERIALS AND METHODS The chemical components of JXZDF were detected and the potential pathway enrichment analyses were conducted based on network pharmacology. Finally, we performed cell viability assays and Western blotting on LPS-induced BV-2 cells, and subsequently performed behavioral tests and Western blotting in SD rats model for TD to explore the mechanism of JXZDF on TD. RESULTS By LC-ESI-MS/MS system and searching the databases, we identified 5 key compounds and 29 hub targets of JXZDF on TD. KEGG enrichment analysis showed that PI3K/AKT signaling pathway may be the key pathway for JXZDF on TD. The vitro experimental results proved that JXZDF can inhibit the phosphorylation of PI3K and AKT proteins on LPS-induced BV-2 cells. The animal experimental results indicated that JXZDF can effectively alleviate the stereotypic behavior and hyperactivity of the TD rats, and downregulated PI3K/AKT pathway to inhibit microglia activation in the hippocampus tissue. CONCLUSION This study indicated that JXZDF can change microglial activation and expression of proinflammatory mediators through the inactivation of PI3K/AKT signaling pathway, which may be one of the mechanisms of JXZDF in treating TD.

Abstract
Periploca forrestii Schltr., a traditional Chinese medicine (TCM), is commonly used to treat autoimmune diseases such as rheumatoid arthritis (RA). However, its mechanism, involving a variety of cardiac glycosides, remains largely unknown. The immune knockout strategy can highly selectively deplete target components by immunoaffinity chromatography (IAC). We aimed to identify the common structural features of cardiac glycosides in P. forrestii and design IAC to specifically recognize these features to achieve the multi-component knockout of potential active substances from the extracts of P. forrestii. A content detection experiment confirmed that the content of a compound with periplogenin structure (CPS) in the extract of P. forrestii was reduced by 45% by IAC of periplogenin. The immunosuppressive ability of the extract on H9 human T lymphocytic cells was weakened after CPS knockout from P. forrestii extract. Molecular biology experiments showed that mRNA expression of interferon-γ (IFN-γ), interleukin-2 (IL-2), and interleukin-6 (IL-6) in H9 cells was up-regulated after CPS knockout, while no significant changes in the expression of interleukin-4 (IL-4) were found. CPS knockout from P. forrestii extract did not cause significant changes in the proliferation of lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells incubated with this extract. These results indicate that CPS exhibited immunosuppressive effects via inhibiting the T helper 1 (Th1) cell immune response and not via the anti-inflammatory components in P. forrestii. This is the first use of IAC to achieve multi-component knockout in TCM extracts for identifying effective compounds. This method is effective and reliable and warrants further exploration.

Shikonin potentiates therapeutic efficacy of oxaliplatin through reactive oxygen species-mediated intrinsic apoptosis and endoplasmic reticulum stress in oxaliplatin-resistant colorectal cancer cells. Drug Dev Res 2023; 84:542-555. [PMID: 36779379 DOI: 10.1002/ddr.22044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 01/16/2023] [Accepted: 01/27/2023] [Indexed: 02/14/2023]
Abstract
Oxaliplatin (OXA) has been recognized as a third-generation platinum-based chemotherapeutic agent with stellar therapeutic efficacy in managing colorectal cancer (CRC). Nevertheless, resistance to OXA in CRC patients hinders its effectiveness. Shikonin (SHI), a natural naphthoquinone derived from Arnebia euchroma (Royle) Johnst., features a broad pharmacological profile and minimal toxicities. To assess the synergism of SHI and OXA towards OXA-resistant CRC cells (HCT116R ), we employed in vitro and in vivo pharmacological assays. Our experiments provided evidence that SHI, either alone or in combination with OXA, considerably reduced cell proliferation, triggered apoptosis, and induced the generation of reactive oxygen species (ROS) in HCT116R cells. Furthermore, the combination of SHI and OXA dramatically curbed the extent of HCT116R -initiated xenograft growth in mouse models. Bioinformatics, western blot, and ROS assays highlighted that the mechanisms of SHI against OXA-resistant CRC cells may involve the induction of cellular responses to chemical stress, intrinsic apoptosis, as well as endoplasmic reticulum stress pathways mediated by ROS. Notably, the synergism of SHI+OXA was partially abrogated by an ROS inhibitor N-acetyl cysteine. Our findings imply the potential of SHI to boost the sensitivity of OXA to CRC, offering promising benefits for clinical strategies to combat OXA resistance.

Discovery and molecular elucidation of the anti-influenza material basis of Banlangen granules based on biological activities and ultra-high performance liquid chromatography coupled with quadrupole-orbitrap mass spectrometry. JOURNAL OF ETHNOPHARMACOLOGY 2022; 298:115683. [PMID: 36057409 DOI: 10.1016/j.jep.2022.115683] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2022] [Revised: 08/24/2022] [Accepted: 08/26/2022] [Indexed: 06/15/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine (TCM) has a wide range of applications, including human healthcare-associated treatments and bioactive compound discovery. However, complex chemical systems present a significant challenge for chemical-material-based research and quality control. For instance, Banlangen (BLG) granules is a well-acknowledged TCM preparation widely used in clinical treatment of virus infection. However, its chemical basis of anti-influenza efficacy remains unclear. AIM OF THE STUDY In the present study, a systematic discovery strategy for identifying anti-influenza molecules based on biological activities and chemical analysis was established to contribute to the molecular elucidation of the anti-influenza material basis of Banlangen granules. MATERIALS AND METHODS Hemagglutinase inhibition (HAI) and neuraminidase inhibition (NAI) assays were used to compare the anti-influenza activities of different fractions of BLG granules against H1N1, H5N1 and H7N9 viruses. A comparative qualitative analysis of the chemical constituents in BLG granules and their fractions was performed using ultra-high-performance liquid chromatography coupled with quadrupole orbitrap mass spectrometry (UHPLC-Q-Exactive Orbitrap MS), in which a multiple mass spectrometry database platform and three compound identification strategies were used. The association between anti-influenza activities and chemical constituent characteristics was analyzed using multiple stoichiometries and data comparison strategies. RESULTS The results showed that the chromatography fractions F3 and F4 of the BLG granules had the highest anti-influenza activity. A total of 88 compounds were identified in the BLG granules, including 31 alkaloids, 16 organic acids, 10 nucleosides, 8 phenylpropanoids, 6 sulfur-containing compounds, 5 amino acids, 4 aromatic compounds, 3 aldehydes and ketones, 2 flavonoids, 1 alcohol, 1 carbohydrate, and 1 aliphatic compound. Out of these, 31 characteristic compounds were identified in fractions F3-F4 as candidate compounds with anti-influenza activity. Additionally, 6-methoxyquinoline and 4-guanidinobutanal were identified in BLG granules and its raw material (Isatidis Radix) for the first time. CONCLUSION In this study, we proposed a systematic discovery strategy to thoroughly investigate the anti-influenza activity, chemical identification, and constituents-activity relationship of BLG granules. These data not only provided a deeper understanding of the molecular mechanism of the activity of BLG granules, but also presented a basis for the discovery of potential novel drug candidates and quality evaluation and control of BLG granules.

Screening and characterization estrogen receptor ligands from Arnebia euchroma (Royle) Johnst. via affinity ultrafiltration LC-MS and molecular docking. FRONTIERS IN PLANT SCIENCE 2022; 13:1012553. [PMID: 36420029 PMCID: PMC9676231 DOI: 10.3389/fpls.2022.1012553] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Accepted: 10/10/2022] [Indexed: 06/16/2023]
Abstract
Arnebiae Radix (dried root of Arnebia euchroma (Royle) Johnst.) is a traditional Chinese medicine (TCM) used to treat macular eruptions, measles, sore throat, carbuncles, burns, skin ulcers, and inflammations. The Arnebiae Radix extract can exert anti-breast cancer effects through various mechanisms of action. This study aimed to rapidly screen potential estrogen receptor (estrogen receptor α and estrogen receptor β) ligands from the Arnebiae Radix extract. In this study, an analytical method based on affinity ultrafiltration coupled with UHPLC-Q-Exactive Orbitrap mass spectrometry was established for rapidly screening and identifying estrogen receptor ligands. Then, bindings of the components to the active site of estrogen receptor (estrogen receptor α and estrogen receptor β) were investigated via molecular docking. Moreover, surface plasmon resonance (SPR) experiments with six compounds were performed to verify the affinity. As a result, a total of 21 ligands were screened from Arnebiae Radix using affinity ultrafiltration. Among them, 14 and 10 compounds from Arnebiae Radix showed affinity with estrogen receptor α and estrogen receptor β, respectively. All of those ligands could have a good affinity for the multiple amino acid residues of the estrogen receptor based on molecular docking. In addition, six compounds display the great affinity by SPR. The method established in the study could be used to rapidly screen estrogen receptor ligands in Traditional Chinese medicine. The results demonstrated that the affinity ultrafiltration-UHPLC-Q-Exactive Orbitrap mass spectrometry method not only aids in the interpretation of the potential bioactive components and possible mechanisms of action of Arnebiae Radix but also provides a further effective basis for the quality control of this valuable herb medicine.

Analysis of Isoflavones in Pueraria by UHPLC-Q-Orbitrap HRMS and Study on α-Glucosidase Inhibitory Activity. Foods 2022; 11:foods11213523. [DOI: 10.3390/foods11213523] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2022] [Revised: 10/26/2022] [Accepted: 10/28/2022] [Indexed: 11/09/2022] Open
Abstract
Pueraria is a rich source of bioactive compounds, but there is a lack of comprehensive information concerning its composition. Therefore, a UHPLC-Q-Orbitrap HRMS method was developed to identify and quantify bioactive compounds in pueraria. Twelve isoflavones were quantified, with puerarin being the most abundant, followed by puerarin 6″-O-xyloside, 3′-methoxy puerarin, and 3′-hydroxy puerarin. A further 88 bioactive components in eight categories were also tentatively identified. The 12 isoflavones, except for genistein, exhibited α-glucosidase inhibitory activity. The binding of these compounds to the active site of α-glucosidase was confirmed via molecular docking analysis. These findings provide a basis for identifying pueraria as a promising functional food ingredient.
