Description

Ochratoxins are mycotoxins produced by Aspergillus and Penicillium species of fungi that contaminate foods. Ochratoxin A (OTA, ) is a chlorinated form with toxicity that targets the kidneys, causing nephropathy and renal adenomas. OTB is a non-chlorinated analog of OTA that has cytotoxic effects on kidney and liver cells in vitro but only minor effects in vivo, due to its rapid metabolism and excretion. OTB inhibits cell proliferation of human liver HepG2 cells at doses as low as 1 μg/ml but lacks the genotoxic activity of OTA, even at higher concentrations.
