Diphenyl ethers from the cultured lichen mycobiont of Graphis handelii Zahlbr. Heliyon 2024; 10:e25763. [PMID: 38404884 PMCID: PMC10884431 DOI: 10.1016/j.heliyon.2024.e25763] [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: 11/19/2023] [Revised: 02/01/2024] [Accepted: 02/01/2024] [Indexed: 02/27/2024] Open
Abstract
Purpose Cultured lichen mycobionts are valuable sources of new natural compounds. Mycobiont of Graphis handelii growing in Vietnam was isolated, cultivated and chemically investigated. The crude extract of this cultured mycobiont showed potent alpha-glucosidase inhibition with an IC50 value of 50 μg/mL. Methods Multiple chromatographic methods were applied to the extract to isolate compounds. The combination of Nuclear Magnetic Resonance analysis and high-resolution mass spectroscopy determined their chemical structures. Electrophilic bromination/chlorination was applied to obtain new derivatives using NaBr/H2O2 and NaCl/H2O2 reagents. Compounds were evaluated for enzyme inhibitory activities, including alpha-glucosidase inhibition, HIV-1 reverse transcriptase inhibition, SARS-CoV-2 main protease (Mpro) inhibition, anti-inflammatory activity, and cytotoxicity against several cancer cell lines. A molecular docking study for anti-SARS-CoV-2 was conducted to understand the inhibitory mechanism. Results A new diphenyl ether, handelone (1) and a known compound xylarinic acid A (2) were isolated and elucidated. Four synthetic products 6'-bromohandelone (1a), 2'-bromohandelone (1b), 2',6'-dibromohandelone (1c), and 2',6'-dichlorohandelone (1d) were prepared. Compound 1 showed good activity against Mpro with an IC50 value of 5.2 μM but it showed weak or inactive activity in other tests. Other compounds were inactive in all assays. Conclusion A new compound, handelone (1) was isolated from the cultured mycobiont of Graphis handelii. From these compounds, four new derivatives were prepared. Compound 1 showed good activity against Mpro with an IC50 value of 5.2 μM but it showed weak or inactive activity in other tests. Other compounds were inactive in all assays.

Anti-Inflammatory Activity of Lauraceae Plant Species and Prediction Models Based on Their Metabolomics Profiling Data. Chem Biodivers 2023; 20:e202300650. [PMID: 37540773 DOI: 10.1002/cbdv.202300650] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2023] [Revised: 08/03/2023] [Accepted: 08/04/2023] [Indexed: 08/06/2023]
Abstract
The Lauraceae is a botanical family known for its anti-inflammatory potential. However, several species have not yet been studied. Thus, this work aimed to screen the anti-inflammatory activity of this plant family and to build statistical prediction models. The methodology was based on the statistical analysis of high-resolution liquid chromatography coupled with mass spectrometry data and the ex vivo anti-inflammatory activity of plant extracts. The ex vivo results demonstrated significant anti-inflammatory activity for several of these plants for the first time. The sample data were applied to build anti-inflammatory activity prediction models, including the partial least square acquired, artificial neural network, and stochastic gradient descent, which showed adequate fitting and predictive performance. Key anti-inflammatory markers, such as aporphine and benzylisoquinoline alkaloids were annotated with confidence level 2. Additionally, the validated prediction models proved to be useful for predicting active extracts using metabolomics data and studying their most bioactive metabolites.

An In Vivo Assessment of the Effect of Hexane Extract from Endlicheria paniculata Branches and Its Main Compound, Methyldehydrodieugenol B, on Murine Sponge-Induced Inflammation. Molecules 2023; 28:5247. [PMID: 37446907 DOI: 10.3390/molecules28135247] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2023] [Revised: 06/21/2023] [Accepted: 07/04/2023] [Indexed: 07/15/2023] Open
Abstract
The present study aims to explore the anti-inflammatory potential activity of the hexane extract from branches (HEB) of Endlicheria paniculata (Lauraceae) and its main compound, methyldehydrodieugenol B, in the inflammatory response induced by a murine implant sponge model. HPLC-ESI/MS analysis of HEB led to the identification of six chemically related neolignans, with methyldehydrodieugenol B as the main compound. An in silico analysis of the pharmacokinetic parameters of the identified compounds suggested moderate solubility but good absorption and biodistribution in vivo. Thus, the treatment of mice with HEB using in vivo assays indicated that HEB promoted pro-inflammatory, antiangiogenic, and antifibrogenic effects, whereas treatment with methyldehydrodieugenol B caused anti-inflammatory, antifibrogenic, and antiangiogenic effects. The obtained results shown the therapeutic potential of HEB and methyldehydrodieugenol B in the treatment of pathologies associated with inflammation and angiogenesis, including chronic wounds.

Ferreira BA, de Moura FBR, Gomes KS, da Silva Souza DC, Lago JHG, Araújo FDA. Biseugenol from Ocotea cymbarum (Lauraceae) attenuates inflammation, angiogenesis and collagen deposition of sponge-induced fibrovascular tissue in mice. Inflammopharmacology 2023; 31:1539-1549. [PMID: 37022573 DOI: 10.1007/s10787-023-01210-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 03/21/2023] [Indexed: 04/07/2023]
Abstract
Several species of the genus Ocotea are used in traditional medicine due to their anti-inflammatory and analgesic properties. In this work we sought to investigate the effects of biseugenol, the main component of the hexane extract from the leaves of Ocotea cymbarum (Lauraceae), during a chronic inflammatory process induced by polyester-polyurethane sponge in mice. In addition to the inflammatory component, sponge discs also allowed us to evaluate parameters associated with the formation of new blood vessels and the deposition and organization of the extracellular matrix, processes that are related to the chronification of the inflammatory response. Daily treatment with biseugenol (0.1, 1 or 10 µg in 10 µl of 0.5% DMSO) inhibited the synthesis of inflammatory cytokines (TNF-α, CXCL-1 and CCL2) and the neutrophil and macrophage infiltrate into to the implants, indirectly evaluated by the activity of myeloperoxidase and N-acetyl-β-D-glycosaminidase enzymes, respectively. In implants treated with biseugenol, we observed a reduction in angiogenesis, assessed through histological quantification of mean number of blood vessels, the levels of the pro-angiogenic cytokines FGF and VEGF and the activity of metalloproteinases. Except for VEGF levels, all mentioned parameters showed significant reductions after treatment with biseugenol. Finally, the administration of the compound also reduced TGF-β1 levels, collagen synthesis and deposition, in addition to modifying the organization of the newly formed matrix, presenting a potential anti-fibrotic effect. Therefore, our results demonstrate the potential therapeutic use of biseugenol for the treatment of a series of pathological conditions, where parameters associated with inflammation, angiogenesis and fibrogenesis are deregulated.
