    Product Description

    Peroxiredoxins are a widely conserved family of enzymes that function in antioxidant defense and act in redox signaling pathways. Increased expression of human peroxiredoxin is associated with cancer, cardiovascular dysfunction, and neurodegeneration. Conoidin A inactivates peroxiredoxins by covalently binding to the catalytic cysteine on the enzyme.1,2 It has been shown to inhibit peroxiredoxin II (IC50 = 23 µM) in the parasite T. gondii and peroxiredoxin I in the hookworm A. ceylanicum.1,2,3 At 5 µM, conoidin A can also inhibit the glucose oxidase-mediated hyperoxidation of mammalian peroxiredoxin I and II, but not peroxiredoxin III.1

    WARNING This product is not for human or veterinary use.
