Bisanthraquinone Metabolites Produced by the Endophytic Fungus Diaporthe sp.

Chemical and Pharmaceutical Bulletin, 2006
Two bisanthraquinones named (+)-epicytoskyrin (1) and (+)-1,1'-bislunatin (2) were produced by the endophytic fungus from a tea plant, which is a species closely related to Diaporthe phaseolorum strain sw-93-13. The chemical structures of the metabolites were elucidated on the basis of the physicochemical properties including the circular dichroism (CD)

NMR‐Based Structural Elucidation of a New Dihydroisocoumarin and Related Polyketides From a Mangrove‐Derived Fusarium sp.

Magnetic Resonance in Chemistry, EarlyView.
Integration of bioactivity screening and LC–MS/MS metabolomics enabled the discovery of a new antibacterial dihydroisocoumarin from Fusarium sp. IQ‐1921. NMR‐based structural elucidation identified five related metabolites, with the new compound 1 showing the broadest activity against multidrug‐resistant bacteria. ABSTRACT Antimicrobial resistance (AMR)

Evolutionary trade‐offs between beauvericin production and growth define divergent virulence strategies in Beauveria

Pest Management Science, EarlyView.
Two virulence strategies in Beauveria: a growth strategy characterized by rapid within‐host proliferation, and a toxin strategy involving antimicrobial activity and toxicity to insects Abstract BACKGROUND Pathogen virulence is often attributed to toxin production, yet toxins are metabolically costly and may not universally enhance fitness.

Bioactive compounds from the endophytic fungus Fusarium proliferatum [PDF]

Natural Product Research, 2015
The crude extract of an endophytic fungus isolated from Syzygium cordatum and identified as Fusarium proliferatum showed 100% cytotoxicity against the brine shrimp Artemia salina at 100 μg/mL. Seven coloured, biologically active metabolites – including ergosta-5,7,22-trien-3β-ol, nectriafurone-8-methyl ether, 9-O-methyl fusarubin, bostrycoidin ...
