Ocratoxina B

Descrição:

Ocratoxina B é uma micotoxina produzida por certas espécies de fungos, particularmente Aspergillus e Penicillium. É um metabolito secundário que está estruturalmente relacionado com a ocratoxina A, diferindo principalmente pela ausência de um grupo de fenilalanina. Este composto é caracterizado por sua estabilidade sob várias condições ambientais, tornando-se uma preocupação na segurança alimentar e na saúde pública. Ocratoxina B exibe propriedades nefrotóxicas, hepatotóxicas e imunossupressoras, representando riscos tanto para a saúde humana quanto animal após a exposição. É comumente encontrado em uma variedade de produtos agrícolas, incluindo cereais, café e frutas secas, muitas vezes como resultado da contaminação fúngica durante o armazenamento. O composto é solúvel em solventes orgânicos, mas tem solubilidade limitada em água. Agências reguladoras monitoram os níveis de ocratoxina em produtos alimentares devido aos seus potenciais efeitos carcinogênicos e sua capacidade de se acumular nos rins. O armazenamento e manuseio adequados de itens alimentares suscetíveis são essenciais para minimizar o risco de contaminação por Ocratoxina 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.
