Conoidin A is a covalent inhibitor of peroxiredoxin II with IC50 value of 23 μM [2].
Peroxiredoxins are a widely conserved family of enzymes that function in antioxidant defense and signal transduction, and changes in PrxII expression are associated with a variety of human diseases, including cancer [1].
Conoidin A is a novel, cell-permeable and covalent peroxiredoxin II inhibitor with IC50 value of 23 μM [1][2]. Conoidin A bound covalently to the peroxidatic cysteine of the T. gondii enzyme peroxiredoxin II (TgPrxII), inhibiting its enzymatic activity. In human epithelial cells, Conoidin A inhibited hyperoxidation of human PrxII [1]. Conoidin A also inactivated AcePrx-1 (a peroxiredoxin from the hookworm Ancylostoma ceylanicum) by alkylating or crosslinking the catalytic cysteines with IC50 value of 374 μM [2]. Conoidin A inhibited the hyperoxidation of two mammalian peroxiredoxin homologues (PrxI and PrxII) in cells [3].

工作液浓度： mg/ml；
DMSO母液配制方法： mg 药物溶于 μL DMSO溶液（母液浓度 mg/mL，
体内配方配制方法：取 μL DMSO母液，加入 μL PEG300，混匀澄清后加入μL Tween 80，混匀澄清后加入 μL saline，混匀澄清。
1. 首先保证母液是澄清的；
2.
一定要按照顺序依次将溶剂加入，进行下一步操作之前必须保证上一步操作得到的是澄清的溶液，可采用涡旋、超声或水浴加热等物理方法助溶。
