[PMID: 36815551 DOI: 10.1080/14786419.2023.2181805] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/03/2023] [Accepted: 02/14/2023] [Indexed: 02/24/2023]
Abstract
A new chromone derivative, aspergione A (1), along with seven known metabolites, was isolated from a mangrove endophytic fungus, Aspergillus sp. GXNU-B1, which was collected from mangrove Acanthus ilicifolius L. Their structures and the absolute configuration of 1 were elucidated based on the analysis of HR-ESI-MS, NMR, and ECD calculation. Compounds 1-8 were evaluated for their anti-inflammatory effects on the production of nitricoxide (NO). Compounds 1 and 8 have potent inhibitory effects against NO production in activated macrophages with IC50 values of 38.26 and 44.30 μM, respectively.

[PMID: 38037915 DOI: 10.1080/14786419.2023.2288685] [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: 07/16/2023] [Accepted: 11/22/2023] [Indexed: 12/02/2023]
Abstract
A new sulphur-containing metabolite, asperiguxidione A (1), was isolated from a mangrove endophytic fungus Aspergillus sp. GXNU-MA, and four known alkaloids 2-5, were isolated together from this strain. Their structures were determined by the com-bination of 1D and 2D NMR spectroscopy, HR-ESI-MS, and ECD analysis. Compounds 1 and 2 exhibited mediate activity against Staphylococcus aureus and Enterobacter aerogenes with equal MIC values of 12.5 μg/mL. Compound 3 reduced NO production in LPS-stimulated cells with an IC50 value of 13.329 ± 0.53 μg/mL in the anti-inflammatory assay.

Molecules 2022; 27:molecules27238160. [PMID: 36500252 PMCID: PMC9737011 DOI: 10.3390/molecules27238160] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2022] [Revised: 11/17/2022] [Accepted: 11/22/2022] [Indexed: 11/25/2022] Open
Abstract
Chemical investigation of the fermentation extract of the mangrove endophytic fungus Aspergillus sp. GXNU-A1, isolated from Acanthus ilicifolius L., discovered an undescribed pair of enantiomers (asperphenyltones A and B (±1)), together with four previously described metabolites: nodulisporol (2), isosclerone (3), 2,3,4-trihydroxy-6-(hydroxymethyl)-5-methylbenzyl alcohol (4), and 4,6-dihydroxy-5-methoxy-7-methyl-1,3-dihydroisobenzofuran (5). Analyses of the 1D and 2D NMR spectroscopic data of the compounds supported their structural assignments. The presence of the asperphenyltones A and B, which are a pair of enantiomers, was established by HR-ESI-MS, 1D and 2D NMR data and confirmed by single-crystal X-ray diffraction analysis. Metabolites 1-5 were evaluated for their anti-inflammatory effects on the production of nitric oxide (NO), and 1, 3, and 4 showed significant potential inhibitory activities against NO production in activated macrophages with IC50 values of 26-40 μM, respectively.
