nitroxides

PTIO 是一种特定的 NO 清除剂。 PTIO 与一氧化氮反应形成二氧化氮和相应的亚氨基氮氧化物。 PTIO 可用于检查一氧化氮合酶抑制活性。

4-carboxy TEMPO is a nitroxide and spin label. Nitroxides such as 4-carboxy TEMPO react with reactive oxygen species (ROS) and can be used with electron spin resonance (ESR) spectroscopy to monitor ROS production in vivo., It has also been used to study flavin-photosensitized damage in inner mitochondrial membranes.
