Citrinin h1
Citrinin H1 is produced out of two citrinin molecules and its toxicity is increased compared to the original toxicity of citrinin. Citrinin H2, a formylated derivative of phenol A, is less toxic than citrinin. Phenol A seems to be produced mainly under acidic conditions. Dicitrinin A is a dimer of citrinin molecules … See more Citrinin is a mycotoxin which is often found in food. It is a secondary metabolite produced by fungi that contaminates long-stored food and it causes different toxic effects, like nephrotoxic, hepatotoxic and cytotoxic effects. … See more Citrinin was one of the many mycotoxins discovered by H. Raistrick and A.C. Hetherington in the 1930s. In 1941 H. Raistrick and G. Smith identified citrinin to have a broad antibacterial activity. After this discovery the interest in citrinin rose. However, in 1946 … See more The existing information on occurrence of citrinin in food suggests that relatively high citrinin concentrations can be found in stored grains and … See more Citrinin is biosynthesized by fungi species of Penicillium, Monascus and Aspergillus. For the production of citrinin, a minimal set of genes is needed. These genes are conserved in most … See more Citrinin is a polyketide mycotoxin, which is a secondary metabolite of some fungi species. Its IUPAC name is (3R,4S)-4,6-dihydro-8-hydroxy-3,4,5-trimethyl-6-oxo-3H-2-benzopyran-7-carboxylic acid and the molecular formula is C13H14O5. Citrinin has a … See more There are different types of toxicity. The types of toxicity that have been studied for citrinin are acute toxicity, nephrotoxicity, genotoxicity See more Various in vitro studies have revealed the involvement of citrinin toxicity in reduced cytokine production, inhibition of RNA and DNA synthesis, induction of oxidative stress, inhibition of nitride oxide gene expression, increase in ROS production and activation of … See more WebPenctrimertone (1), a novel citrinin dimer bearing a 6/6/6/6 tetracyclic ring scaffold, along with two known compounds xerucitrinic acid A (2) and citrinin (3) were isolated from the endophytic fungus Penicillium sp.
