Description | Conoidin A is a cell permeable inhibitor of T. gondii enzyme peroxiredoxin II (TgPrxII) with nematicidal properties. Conoidin A covalently binds to the peroxidatic Cys47 of TgPrxII, irreversibly inhibiting its hyperperoxidation activity with an IC50 of 23 µM. 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[3]. |

In Vitro | Peroxiredoxins are a widely conserved family of enzymes that function in antioxidant defense and signal transduction. And the changes in PrxII expression are associated with a variety of human diseases, including cancer[1]. Conoidin A binds to the peroxidatic cysteine of TgPrxII, inhibiting its enzymatic activity in vitro. Conoidin A also shown to alkylate or crosslink catalytic cysteines of wild type AcePrx-1 in Ancylostoma ceylanicum and human PrxII and PrxIV with similar efficiency. But it is ineffective to mitochondrial hPrxIII[2]. Conoidin A (5 µM) can inhibit the glucose oxidase-mediated hyperoxidation of mammalian peroxiredoxin I and II[2]. |
In Vivo | Conoidin A (intraperitoneal injection; 5 mg/kg; for three successive days before MI/R injury) blocks the effect of Luteolin (HY-N0162) on the ST‐segment elevation. Furthermore, an increase in the infarct size presented of the MI/R group can be reduced by Luteolin. But pre‐treatment with conoidin A abolishs the effect of Luteolin. Pre‐treatment with conoidin A also prevents Luteolin-reduced activities of CK‐MB, AST and LDH in vivo[3]. Animal Model: Rat myocardial I/R model[3] Dosage: 5 mg/kg Administration: Intraperitoneal injection; 5 mg/kg; for three successive days before MI/R injury Result: Significantly reversed the antioxidative effect of Luteolin. Impaired the protective effects of luteolin. |
