Conoidin A is a cell permeable inhibitor of燭. gondii爀nzyme peroxiredoxin II (TgPrxII). Conoidin A covalently binds to the peroxidatic Cys47 of TgPrxII, irreversibly inhibiting its hyperperoxidation activity with an營C50爋f 23 礛. Conoidin A also inhibits hyperoxidation of mammalian PrxI and PrxII (but not PrxIII)[1][2]. Conoidin A has antioxidant, neuroprotective effects and can be used for the research of ischaemic heart disease
