Adsorption of Zearalenone by Montmorillonite

Advanced Materials Research, 2013
In vitro adsorption of zearalenone (ZEA) by montmorillonite (MONT) and organomodified MONT was investigated. Effects of dioctadecylmethylbenzyl ammonium chloride (DOMBAC) amount and interaction temperature were studied and when the MONT was reacted with DOMBAC of 1.44 mmol g-1 at 90 °C, the sample exhibited the highest adsorption capacity of ZEA (93.6%)

Total synthesis of the macrolide, zearalenone

Tetrahedron, 1967
Abstract Total synthesis of the biologically active macrolide zearalenone together with its optical resolution and the determination of its absolute configuration as “S” are described. Wittig condensation with an ortho aldehydic ester proceeded in part with vicinal interaction and formation of an acetylenic product.

Transgenerational toxicity of Zearalenone in pigs

Reproductive Toxicology, 2012
Zearalenone (ZEN) is a mycotoxin that can be a contaminant of food and feed commodities. ZEN acts as a xenoestrogen and is considered an endocrine disruptor. Since estrogens influence oogenesis during fetal growth, the effect of ZEN on oocytes was investigated in the F1-generation. Pregnant and lactating pigs were exposed to feed naturally contaminated

Metabolism of zearalenone by Fusarium Roseum

Journal of Toxicology and Environmental Health, 1977
Twenty products associated with the metabolism of zearalenone by Fusarium roseum were analyzed with respect to time and culture conditions. By statistical analysis a set of six metabolites possibly related to zearalenone were selected. These products were characterized by gas chromatography--mass spectrometry and other methods.

Zearalenone as an endocrine disruptor in humans

Environmental Toxicology and Pharmacology, 2016
Zearalenone (ZEA), a fungal mycotoxin, is present in a wide range of human foods. Many animal studies have found ZEA to possess a disruptive effect on the hormonal balance, mainly due to its similarity to naturally-occurring estrogens. With increasing consciousness of the adverse effects of endocrine disruptors on human health, it is becoming more ...

Metabolism of Zearalenone in Rat Liver

Acta Pharmacologica et Toxicologica, 1978
Abstract The metabolism of zearalenone in rat liver has been investigated. The studies were performed mainly with liver homogenate, though isolated microsomes and hepatocytes have also been used. Zearalenone was metabolized along two principal pathways, conjugation with glucuronic acid, which was the main route and reduction to an isomer of zearalenol.

Toxicokinetic Studies in Piglets Reveal Age-Related Differences in Systemic Exposure to Zearalenone, Zearalenone-14-Glucoside, and Zearalenone-14-Sulfate

Journal of Agricultural and Food Chemistry, 2020
Juveniles are considered as one of the most vulnerable population groups concerning mycotoxins and their modified forms. The weaning stage is a particularly vulnerable period in the life of mammals, reflected in intestinal and immune dysfunction. The current study investigated the toxicokinetic (TK) characteristics of zearalenone (ZEN), zearalenone-14 ...

Effect of zearalenone on dairy cows

American Journal of Veterinary Research, 1986
SUMMARY Doses of 99% pure zearalenone (0.0, 31.25, 62.5, 125.0, 250.0, or 500.0 mg) in gelatin capsules were given once a day per os to 18 nonpregnant, nonlactating, multiparous dairy cows for 2 consecutive estrous cycles. There was no effect (P < 0.10) on serum progesterone concentrations, rbc, wbc, pcv, hemoglobin, and estrous cycle length ...

Identification of a Potent Enzyme for the Detoxification of Zearalenone.

Journal of Agricultural and Food Chemistry, 2019
The occurrence of mycotoxin zearalenone (ZEN) and its derivatives have been a severe global threat to food and animals. In addition to the chemical and physical degradation methods, a powerful biocatalyst is urgently required for the detoxification ZEN ...
