GNPS2 molecular networking reveals metabolic diversity in fungi isolated from protease-rich fruits.
Article in Natural products and bioprospecting, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Fungi are a rich source of chemical diversity for bioprospecting, yet most of their metabolic potential remains unexplored. This study investigated the metabolic profile of phytopathogenic fungi of the genus Fusarium, isolated from fruits with high protease content, such as papaya and pineapple. Comparative metabolomics was used to evaluate how culture substrates and co-cultivation with the endophyte Neofusicoccum ribis modulate secondary metabolite production. Molecular Networking analysis (GNPS2) revealed an impressive diversity of 173 annotated metabolites, including one previously undescribed compound. Metabolite production was highly dependent on the substrate and fungal strain, showing a strong correlation between phylogeny and metabolic profiles. Several extracts displayed significant inhibitory activity against the protease papain, with some co-cultivation combinations further enhancing this effect. These findings highlight how environmental conditions and microbial interactions activate silent biosynthetic pathways, confirming these fungi as promising sources for bioactive molecule discovery.
