A Novel and Potentially Multifaceted Dehydroascorbate Reductase Increasing the Antioxidant Systems is Induced by Beauvericin in Tomato

Antioxidants, 2020
Dehydroascorbate reductases (DHARs) are important enzymes that reconvert the dehydroascorbic acid (DHA) into ascorbic acid (ASC). They are involved in the plant response to oxidative stress, such as that induced by the mycotoxin beauvericin (BEA). Tomato

Role of Nrf2 Nucleus Translocation in Beauvericin-Induced Cell Damage in Rat Hepatocytes

Toxins, 2022
Beauvericin (BEA), a food-borne mycotoxin metabolite derived from the fungus Beauveria Bassiana, is proven to exhibit high hepatotoxicity. However, the molecular mechanism underlying BEA-induced liver damage is not fully understood. Herein, the effect of

Pilot Study: Does Contamination with Enniatin B and Beauvericin Affect the Antioxidant Capacity of Cereals Commonly Used in Animal Feeding?

Plants, 2021
Increasing consumption of cereals has been associated with reduced risk of several chronic diseases, as they contain phytochemicals that combat oxidative stress. Cereal contamination by the “emerging mycotoxins” beauvericin (BEA) and enniatins (ENs) is a

Chemical Constituents of the Deep‐Sea‐Derived Fungus Talaromyces wortmannii and Their Ferroptosis Inhibitory Activity

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
One new tyramine derivative (1) and 28 known compounds (2–29) were isolated from deep‐sea‐derived fungus Talaromyces wortmannii. Their structures were elucidated by NMR/MS and computational calculations. Compounds 2 and 6 potently inhibited ferroptosis with EC5₀ values of 4.52 and 13.73 µM.
