一般說明
2-（4-羧苯基）-4,4,5,5-四甲基咪唑啉-1-氧基-3-氧化物（羧基-PTIO）主要被认为是一氧化氮（NO）清除剂。
應用
羧基-PTIO钾盐通过检查反应混合物中羟基自由基或硝酸的生成情况，确定反应混合物中一氧化氮的生成情况。还可添加至神经元，分析其对葡萄糖/氧气/血清剥夺（GOSD）状态的影响（4）
生化／生理作用
其与一氧化氮反应可形成羧基-PTI衍生物，产物可进一步抑制一氧化氮合成酶的活性。
羧基-PTIO可以与一氧化氮（NO）快速反应生成二氧化氮（NO2）。 可用于预防 体内脂多糖刺激引起的低血压和内毒素性休克。羧基-PTIO还可以阻断 体外 NO刺激造成的血管松弛。

We recently found a new class of nitric oxide (NO) antidote, i.e., 2-phenyl-4,4,5,5,-tetramethylimidazoline-1-oxyl-3-oxide derivatives (PTIOs). It has a potent inhibitory action against endothelium-derived relaxing factor. Here, we report the effect of a water-soluble carboxy derivative of PTIO (carboxy-PTIO) on endotoxin
