Ocratossina B

Descrizione:

Ocratossina B è una micotossina prodotta da alcune specie di funghi, in particolare Aspergillus e Penicillium. È un metabolita secondario che è strutturalmente correlato all'ochratossina A, differendo principalmente per l'assenza di un gruppo fenilalanina. Questo composto è caratterizzato dalla sua stabilità in varie condizioni ambientali, rendendolo una preoccupazione per la sicurezza alimentare e la salute pubblica. Ocratossina B presenta proprietà nefrotossiche, epatotossiche e immunosoppressive, comportando rischi sia per la salute umana che animale in caso di esposizione. Si trova comunemente in una varietà di prodotti agricoli, tra cui cereali, caffè e frutta secca, spesso a causa della contaminazione fungina durante lo stoccaggio. Il composto è solubile in solventi organici ma ha una solubilità limitata in acqua. Le agenzie di regolamentazione monitorano i livelli di ocratossina nei prodotti alimentari a causa dei suoi potenziali effetti cancerogeni e della sua capacità di accumularsi nei reni. Un corretto stoccaggio e manipolazione degli alimenti suscettibili sono essenziali per ridurre al minimo il rischio di contaminazione da Ocratossina B.

Ochratoxin B

CAS: 4825-86-9

Ochratoxin B is a mycotoxin that belongs to the group of toxic substances produced by fungi. It is found in animal feed and can contaminate food and water. Ochratoxin B has been shown to be genotoxic, inducing DNA damage in human serum, ochratoxin, tubule cells, and liver cells. It also inhibits the activity of complex enzymes such as DNA gyrase and topoisomerase II. The LC-MS/MS method for detecting ochratoxin B was developed based on its ability to react with an optical sensor that changes color when it binds to the substrate molecule. The hybridoma cell line was used to detect monoclonal antibodies against Ochratoxin B using a sample preparation technique with a detection sensitivity of 0.01 ng/mL.
