[PMID: 38030026 DOI: 10.1016/j.jep.2023.117509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 11/14/2023] [Accepted: 11/23/2023] [Indexed: 12/01/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Artemisia mongolica is well known for its use in folk medicine, it is commonly used to alleviate a variety of diseases associated with inflammation, such as laryngitis, tonsillitis, headaches and hepatitis in northwest China. However, its anti-inflammatory mechanism is still unknown. AIM OF THE STUDY The most potential anti-inflammatory part (AMPA) was identified by screening individual parts of A. Mongolica. After the network pharmacological analysis, the anti-inflammation effects and molecular mechanisms of AMPA were evaluated in RAW264.7 cells induced by LPS. MATERIALS AND METHODS AMPA was chosen as the most anti-inflammatory of the A. Mongolica, as measured by the effect of each part of the A. Mongolica on NO and COX-2. The chemical composition of AMPA was identified using HPLC-Q-TOF-MS/MS, and targets of bioactive chemicals and targets related to inflammation were found using open-source databases. The "Compound-targets" network and PPI network were established by combining compounds and overlapped targets, and targets in the PPI networks were analyzed by GO and KEGG enrichment. The RAW26.7 cells induced by LPS were used as a model of inflammation examination. MTT assay was performed to assess the cytotoxicity of AMPA on LPS-induced RAW264.7 cells. The level of NO was measured by the Griess method while the inflammatory factors were detected by ELISA. The protein expression levels of iNOS, COX-2, MAPK, NF-κB signaling pathway and AMPK/Nrf2-related proteins were determined by Western blot. The results of nuclear translocation of p65 and Nrf2 were analyzed by immunofluorescence assay. RESULTS A total of 18 compounds with potential bioactivity were identified, and after intersecting 640 compound-predicted targets and 1608 inflammation targets, the compounds and intersected targets were utilized to structure "compound-target" and PPI networks. Among AMPA, AM6, AM7, AM11, AM8 and AM1 compounds were essential in the "compound-targets" network, meanwhile, TNF, RELA, MAPK1, NOS2, PRKAG, and PTGS2 targets play important roles in the PPI network. The top 10 terms and pathways were obtained based on GO and KEGG. The cell experiments show that 50 μg/mL was the maximum concentration of AMPA without cytotoxicity in the LPS-induced RAW264.7 cell model. When compared with the LPS group, AMPA treatment not only effectively suppressed the generation of NO, TNF-α, IL-6, PGE2, IL-1β and MCP-1 in LPS-induced RAW264.7 cells, but also down-regulated the expression of COX-2, iNOS and the protein levels p-ERK, p-p38, p-IκB-α and p-p65, inhibited the nuclear translocation of p65. Furthermore, the expression levels of p-LKB1, p-AMPK, Nrf2 and HO-1 proteins were up-regulated and Nrf2 nuclear translocation was promoted. CONCLUSION AMPA should be considered an anti-inflammatory agent for the results of network pharmacology and in vitro, which could inhibit the MAPK pathway and NF-κB pathway and activate the AMPK/Nrf2 pathway in LPS-stimulated RAW264.7 cells.

[PMID: 35799933 PMCID: PMC9214608 DOI: 10.1039/d2ra01213h] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 06/08/2022] [Indexed: 11/21/2022] Open
Abstract
Discovering SARS-CoV-2 inhibitors from natural sources is still a target that has captured the interest of many researchers. In this study, the compounds (1-18) present in the methanolic extract of Helichrysum bracteatum were isolated, identified, and their in vitro inhibitory activities against SARS-CoV-2 main protease (Mpro) was evaluated using fluorescence resonance energy transfer assay (FRET-based assay). Based on 1D and 2D spectroscopic techniques, compounds (1-18) were identified as 24-β-ethyl-cholesta-5(6),22(23),25(26)-triene-3-ol (1), α-amyrin (2), linoleic acid (3), 24-β-ethyl-cholesta-5(6),22(23),25(26)-triene-3-O-β-d-glucoside (4), 1,3-propanediol-2-amino-1-(3',4'-methylenedioxyphenyl) (5), (-)-(7R,8R,8'R)-acuminatolide (6), (+)-piperitol (7), 5,7,4'-trihydroxy-8,3'-dimethoxy flavanone (8), 5,7,4'-trihydroxy-6-methoxy flavanone (9), 4',5-dihydroxy-3',7,8-trimethoxyflavone (10), 5,7-dihydroxy-3',4',5',8-tetramethoxy flavone (11), 1,3-propanediol-2-amino-1-(4'-hydroxy-3'-methoxyphenyl) (12), 3',5',5,7-tetrahydroxy-6-methoxyflavanone (13), simplexoside (piperitol-O-β-d-glucoside) (14), pinoresinol monomethyl ether-β-d-glucoside (15), orientin (16), luteolin-3'-O-β-d-glucoside (17), and 3,5-dicaffeoylquinic acid (18). Compounds 6, 12, and 14 showed comparable inhibitory activities against SARS-CoV-2 Mpro with IC50 values of 0.917 ± 0.05, 0.476 ± 0.02, and 0.610 ± 0.03 μM, respectively, compared with the control lopinavir with an IC50 value of 0.225 ± 0.01 μM. The other tested compounds showed considerable inhibitory activities. The molecular docking study for the tested compounds was carried out to correlate their binding modes and affinities for the SARS-CoV-2 Mpro enzyme with the in vitro results. Analyzing the results of the in vitro assay together with the obtained in silico results led to the conclusion that phenylpropanoids, lignans, and flavonoids could be considered suitable drug leads for developing anti-COVID-19 therapeutics. Moreover, the phenylpropanoid skeleton oxygenated at C3, C4 of the phenyl moiety and at C1, C3 of the propane parts constitute an essential core of the SARS-CoV-2 Mpro inhibitors, and thus could be proposed as a scaffold for the design of new anti-COVID-19 drugs.

Abstract
Numerous oxidative transformations of lignan structures have been reported in the literature. In this paper we present an overview on the current findings in the field. The focus is put on transformations targeting a specific structure, a specific reaction, or an interconversion of the lignan skeleton. Oxidative transformations related to biosynthesis, antioxidant measurements, and total syntheses are mostly excluded. Non-metal mediated as well as metal mediated oxidations are reported, and mechanisms based on hydrogen abstractions, epoxidations, hydroxylations, and radical reactions are discussed for the transformation and interconversion of lignan structures. Enzymatic oxidations, photooxidation, and electrochemical oxidations are also briefly reported.

Molecules 2018; 23:E617. [PMID: 29522428 PMCID: PMC6017925 DOI: 10.3390/molecules23030617] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2018] [Revised: 02/18/2018] [Accepted: 03/07/2018] [Indexed: 12/14/2022] Open
Abstract
The speciation of a methanolic extract of Zanthoxylum armatum stem bark has enabled the isolation and characterization of 11 known lignans. Among them, five compounds (6, 8-11) are reported in this plant for the first time. All of the chemical structures were elucidated on the basis of NMR spectral analysis. Additionally, their antifeedant activities against Tribolium castaneum were evaluated scientifically. Among them, asarinin (1), with an EC50 of 25.64 ppm, exhibited a much stronger antifeedant activity than the positive control, toosendanin (EC50 = 71.69 ppm). Moreover, fargesin (2), horsfieldin (3), and magnolone (10), with EC50 values of 63.24, 68.39, and 78.37 ppm, showed almost the same antifeedant activity as the positive control. From the perspective of structure-effectiveness relationship, compounds with the chemical group of methylenedioxy exhibited higher antifeedant activities and have potential to be developed into novel antifeedants or potential lead compounds to protect food and crops in storage.

Abstract
The methanol extract of sesame (Sesamum indicum) seeds was fractionated and purified with the assistance of conventional column chromatography to afford 29 compounds including seven furofuran lignans. Among these isolates, (+)-samin (1) was obtained from the natural source for the first time. In addition, (-)-asarinin (30) and sesamol (31) were generated by oxidative derivation from (+)-sesamolin (2) and (+)-sesamin (3), two abundant lignans found in sesame seeds. To evaluate their in vitro antioxidant potential, the seven isolated lignans (1-7) and the two derivatives (30 and 31) were examined for the scavenging activities on DPPH free radicals and superoxide anions. Moreover, the capability of chelating ferrous ions and reducing power of these sesame lignans were also measured. The results suggest that, besides the well-known sesamolin and sesamin, the minor sesame lignans (+)-(7S,8'R,8R)-acuminatolide (5), (-)-piperitol (6), and (+)-pinoresinol (7) are also adequate active ingredients and may be potential sources for nutritional and pharmacological utilization.
