Depicting the Chemical Diversity of Bioactive Meroterpenoids Produced by the Largest Organism on Earth. Angew Chem Int Ed Engl 2024; 63:e202318505. [PMID: 38390787 DOI: 10.1002/anie.202318505] [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: 12/03/2023] [Revised: 02/14/2024] [Accepted: 02/15/2024] [Indexed: 02/24/2024]
Abstract
In this investigation, we explored the diversity of melleolide-type meroterpenoids produced by Armillaria ostoyae, one of the largest and oldest organisms on Earth, using extracts from liquid and solid fermentation media. The study unveiled three unprecedented dimeric bismelleolides and three novel fatty-acid-substituted congeners, along with 11 new and 21 known derivatives. The structures were elucidated by 1D and 2D NMR spectroscopy and HRESI-MS, and ROESY spectral analysis for relative configurations. Absolute configurations were determined from crystal structures and through ECD spectra comparison. A compound library of melleolide-type meroterpenoids facilitated metabolomics-wide associations, revealing production patterns under different culture conditions. The library enabled assessments of antimicrobial and cytotoxic activities, revealing that the Δ2,4 double bond is not crucial for antifungal activity. Cytotoxicity was linked to the presence of an aldehyde at C1, but lost with hydroxylation at C13. Chemoinformatic analyses demonstrated the intricate interplay of chemical modifications on biological properties. This study marks the first systematic exploration of Armillaria spp. meroterpenoid diversity by MS-based untargeted metabolomics, offering insight into structure-activity relationships through innovative chemoinformatics.

Zhan J, Yuan J, Liu J, Zhang F, Yu F, Wang Y. Metabolomics analysis of mycelial exudates provides insights into fungal antagonists of Armillaria. Mycology 2023; 14:264-274. [PMID: 37583453 PMCID: PMC10424624 DOI: 10.1080/21501203.2023.2238753] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Accepted: 07/15/2023] [Indexed: 08/17/2023] Open
Abstract
The genus Armillaria has high edible and medical values, with zones of antagonism often occurring when different species are paired in culture on agar media, while the antagonism-induced metabolic alteration remains unclear. Here, the metabolome of mycelial exudates of two Chinese Armillaria biological species, C and G, co-cultured or cultured separately was analysed to discover the candidate biomarkers and the key metabolic pathways involved in Armillaria antagonists. A total of 2,377 metabolites were identified, mainly organic acids and derivatives, lipids and lipid-like molecules, and organoheterocyclic compounds. There were 248 and 142 differentially expressed metabolites between group C-G and C, C-G, and G, respectively, and fourteen common differentially expressed metabolites including malate, uracil, Leu-Gln-Arg, etc. Metabolic pathways like TCA cycle and pyrimidine metabolism were significantly affected by C-G co-culture. Additionally, 156 new metabolites (largely organic acids and derivatives) including 32 potential antifungal compounds, primarily enriched into biosynthesis of secondary metabolites pathways were identified in C-G co-culture mode. We concluded that malate and uracil could be used as the candidate biomarkers, and TCA cycle and pyrimidine metabolism were the key metabolic pathways involved in Armillaria antagonists. The metabolic changes revealed in this study provide insights into the mechanisms underlying fungal antagonists.

Viruses 2022; 14:v14020360. [PMID: 35215953 PMCID: PMC8878895 DOI: 10.3390/v14020360] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2021] [Revised: 02/07/2022] [Accepted: 02/08/2022] [Indexed: 11/16/2022] Open
Abstract
To discover sources for novel anti-influenza drugs, we evaluated the antiviral potential of nine extracts from eight medicinal plants and one mushroom (Avena sativa L., Hordeum vulgare Linn. var. nudum Hook. f., Hippophae rhamnoides Linn., Lycium ruthenicum Murr., Nitraria tangutorum Bobr., Nitraria tangutorum Bobr. by-products, Potentilla anserina L., Cladina rangiferina (L.) Nyl., and Armillaria luteo-virens) from the Qinghai–Tibetan plateau against the influenza A/H3N2 virus. Concentrations lower than 125 μg/mL of all extracts demonstrated no significant toxicity in MDCK cells. During screening, seven extracts (A. sativa, H. vulgare, H. rhamnoides, L. ruthenicum, N. tangutorum, C. rangiferina, and A. luteo-virens) exhibited antiviral activity, especially the water-soluble polysaccharide from the fruit body of the mushroom A. luteo-virens. These extracts significantly reduced the infectivity of the human influenza A/H3N2 virus in vitro when used at concentrations of 15.6–125 μg/mL. Two extracts (N. tangutorum by-products and P. anserina) had no A/H3N2 virus inhibitory activity. Notably, the extract obtained from the fruits of N. tangutorum and N. tangutorum by-products exhibited different anti-influenza effects. The results suggest that extracts of A. sativa, H. vulgare, H. rhamnoides, L. ruthenicum, N. tangutorum, C. rangiferina, and A. luteo-virens contain substances with antiviral activity, and may be promising sources of new antiviral drugs.

Abstract
Natural products have been a great source for drug leads, due to a vast majority possessing unique chemical structures. Such an example is the protoilludane class of natural products which contain an annulated 5/6/4-ring system and are almost exclusively produced by fungi. They have been reported to possess a diverse range of bioactivities, including antimicrobial, antifungal and cytotoxic properties. In this review, we discuss the isolation, structure elucidation and any reported bioactivities of this compound class, including establishment of stereochemistry and any total syntheses of these natural products. A total of 180 protoilludane natural products, isolated in the last 70 years, from fungi, plant and marine sources are covered, highlighting their structural diversity and potential in drug discovery.

Abstract
A fibrinolytic enzyme was purified from the cultured mycelia of Armillaria mellea by ion-exchange chromatography followed by gel filtration, and was designated A. mellea metalloprotease (AMMP). The purification protocol resulted in a 627-fold purification of the enzyme, with a final yield of 6.05%. The apparent molecular mass of the purified enzyme was estimated to be 21kDa by SDS-PAGE, fibrin-zymography and gel filtration chromatography, which revealed a monomeric form of the enzyme. The optimal reaction pH value and temperature were, pH 6.0, and 33 degrees C, respectively. This protease effectively hydrolyzed fibrinogen, preferentially digesting the Aalpha-chain over the Bbeta- and r-chains. Enzyme activity was inhibited by Cu(2+) and Co(2+), but enhanced by the addition of Ca(2+) and Mg(2+) ions. Furthermore, AMMP activity was potently inhibited by EDTA, and was found to exhibit a higher specificity for the substrate S-2586 for chymotrypsin, indicating that the enzyme is a chymotrypsin-like metalloprotease. The first 24 amino acid residues of the N-terminal sequence were MFSLSSRFFLYTLCL SAVAVSAAP, which is extremely similar to the 24 amino acid residues of the N-terminal sequence of the fruiting body of A. mellea. These data suggest that the fibrinolytic enzyme AMMP, obtained from the A. mellea exhibits a profound fibrinolytic activity. The mycelia of A. mellea may thus represent a potential source of new therapeutic agents to treat thrombosis.
