ochratoxin c

Ochratoxin C is a toxic metabolite from Aspergillus orchraceus.

Ochratoxin A-13C20 is intended for use as an internal standard for the quantification of ochratoxin A by GC- or LC-MS. Ochratoxin A (T75659) is a mycotoxin that has been found inAspergillusandPenicillium.1It increases lipid peroxide levels and the number of apoptotic cells, as well as reduces superoxide dismutase activity in rat kidney when administered at a dose of 120 μg/kg.2Topical application of ochratoxin A (80 μg/mouse) induces DNA damage, cell cycle arrest at the G0/G1phase, and apoptosis in mouse skin cells.1It also initiates tumor formation in a two-stage mouse skin tumorigenesis model. Ochratoxin A (T75659) has been found as a contaminant in a variety of foods.3

1-N-Methyl-4-mercaptohistidine disulfide is a potential redox regulator of the chloroplast coupling factor 1 (CF1) in C. dubia, acting as the oxidized form of ovothiol A to inhibit light-triggered CF1 ATPase activity. 1-N-Methyl-4-mercaptohistidine disulfide possesses antioxidant, enzyme regulatory, and signal modulation functions.

Ochratoxin TC is an ochratoxin C analog.
