Impact of Nigrospora oryzae‐Derived Natural Products on Photosynthesis and Oxidative Stress in Eichhornia crassipes

Physiologia Plantarum, Volume 177, Issue 1, January/February 2025.
Abstract Interest in natural herbicides has been growing due to government policies restricting synthetic herbicide use in many countries. In that regard, this study investigates the potential of Nigrospora oryzae extract as a natural herbicide against the aquatic invasive weed Eichhornia crassipes.

Anticancer Effect of Mycotoxins From Penicillium aurantiogriseum: Exploration of Natural Product Potential

International Journal of Microbiology, Volume 2024, Issue 1, 2024.
Research into biologically natural substances with antitumor properties, known for their potential to induce fewer side effects and exhibit specificity toward cancerous cells, remains imperative. The pressing demand for novel agents in cancer therapy underscores the intensive investigation of natural products from microorganisms.

Antimicrobial Azaphilones from the Xylariaceous Inedible Mushrooms

International Journal of Medicinal Mushrooms, 2005
In the course of our investigation of biologically active substances from inedible mushrooms, we studied the chemical constituents of six species belonging to the Xylariaceae family (Sardariomycetideae) and isolated various types of azaphilone derivatives, which showed moderate to strong antimicrobial activity, such as entonaemins A–C (1–3), together ...

Absolute Configuration of Fusarone, a New Azaphilone from the Endophytic Fungus Fusarium sp. Isolated from Melia azedarach, and of Related Azaphilones

Chirality, 2012
ABSTRACTA new azaphilone derivative, named fusarone (1), has been isolated from the ethyl acetate soluble extract of the fermentation broth of an endophytic fungus, Fusarium sp. LN‐12, isolated from the leaves of Melia azedarach Linn. The structure of the new compound was established on the basis of extensive spectroscopic analysis, including 1D‐NMR ...

Structure-specific Inhibition of Cholesteryl Ester Transfer Protein by Azaphilones.

The Journal of Antibiotics, 1999
The effect of thirteen different fungal azaphilones, which have a common 6-iso-chromane-like ring, was tested on cholesteryl ester transfer protein (CETP) activity in vitro. Chaetoviridin B showed the most potent inhibitory activity with an IC50 value of < 6.2 microM, followed by sclerotiorin with an IC50 value of 19.4 microM. Rotiorin, chaetoviridin A

Chromatin-mediated upregulation of Monascus pigments in Talaromyces purpurogenus OUCMDZ-019 via disruption of Ash2

Mycology
Monascus pigments (MPs) are important azaphilone-type polyketide pigments, yet yield control, stability, and safety pose challenges. Using an epigenetic derepression strategy, we constructed an Ash2 deletion mutant in the acidophilic fungus Talaromyces ...
