Metabolite Identification
Common NameChaetoglobosin D
DescriptionChaetoglobosin D is a secondary metabolite belonging to the class of polyketides, isolated from the endophytic fungus MG2. This compound has demonstrated significant antifungal activity, particularly against the apple tree pathogen Valsa canker, with an EC50 value indicating complete inhibition at a concentration of 2 μg/mL, which led to protoplast extrusion (PMID:40744597 ). The structure of chaetoglobosin D was elucidated through extensive spectroscopic analyses (PMID:40744597 ). Its protective and therapeutic efficacies were shown to be 91.15% and 88.26%, respectively, in indoor detached twigs against apple Valsa canker (PMID:40744597 ). Notably, chaetoglobosin D exhibited comparable efficacy to the commercial fungicide pyraclostrobin in controlling this pathogen (PMID:40744597 ). Mechanistically, it was found to induce an increase in chitinase activity, elevate cell membrane conductivity, increase malondialdehyde levels, deplete ergosterol content, and enhance the accumulation of reducing sugars in the target fungi (PMID:40744597 ). Additionally, chaetoglobosin D has shown inhibitory effects on nine other pathogenic fungi, marking it as a promising candidate for further research in antifungal applications (PMID:40744597 ).
