Descripción

General description

A cell-permeable dibromomethylquinoxaline-dioxide compound with nematicidal properties that covalently binds to the peroxidatic cysteine of peroxiredoxin II in Toxoplasma gondii (TgPrxII) and irreversibly blocks its hyperperoxidation activity (IC₅₀ = 23 µM). Also shown to alkylate or crosslink catalytic cysteines of wild type AcePrx-1 in Ancylostoma ceylanicum and human PrxII and PrxIV to inhibit their catalytic activity with similar efficiency. Ineffective towards mitochondrial hPrxIII.
