:Ocratoxina B
Descripción:
Ocratoxina B es una micotoxina producida por ciertas especies de hongos, particularmente Aspergillus y Penicillium. Es un metabolito secundario que está estructuralmente relacionado con la ocratoxina A, diferenciándose principalmente por la ausencia de un grupo de fenilalanina. Este compuesto se caracteriza por su estabilidad bajo diversas condiciones ambientales, lo que lo convierte en una preocupación en la seguridad alimentaria y la salud pública. Ocratoxina B exhibe propiedades nefrotóxicas, hepatotóxicas e inmunosupresoras, lo que plantea riesgos tanto para la salud humana como animal tras la exposición. Se encuentra comúnmente en una variedad de productos agrícolas, incluidos cereales, café y frutas secas, a menudo como resultado de la contaminación fúngica durante el almacenamiento. El compuesto es soluble en disolventes orgánicos pero tiene una solubilidad limitada en agua. Las agencias reguladoras monitorean los niveles de ocratoxina en los productos alimenticios debido a sus posibles efectos carcinogénicos y su capacidad para acumularse en los riñones. Un almacenamiento y manejo adecuados de los alimentos susceptibles son esenciales para minimizar el riesgo de contaminación por Ocratoxina B.

CAS: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.
