Xanthine oxidase (XO) generates reactive oxygen species, including hydrogen peroxide (H2O2), as it oxidizes specific substrates in the presence of water and oxygen. 6-Formylpterin is an oxidized pterin produced by photolytic breakdown of folic acid. It binds to one of two active sites on XO nearly quantitatively and irreversibly and prevents the metabolism of other substrates at the second site, resulting in "hetero-substrate" inhibition at nanomolar concentrations. However, 6-formylpterin itself is converted by XO to 6-carboxylpterin and H2O2 and the turnover rate of this reaction can actually be accelerated by prior binding of a hetero-substrate to XO. In this way, 6-formylpterin acts as an intracellular generator of H2O2 in cells expressing XO, altering cellular function.

计算结果:
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。
