2003年12月19日 · We have generated electrochemically the oxidized and reduced forms of PTIO and carboxy-PTIO (C-PTIO), characterized their absorption spectra, and determined the reduction potentials for the oxoammonium/nitroxide and nitroxide/hydroxylamine couples.

Carboxy-PTIO还可用于NO的电子顺磁共振（EPR）检测。 研究显示，Carboxy-PTIO抑制乙酰胆碱诱导的大鼠主动脉环舒张效应，比L-NOARG活性强两倍。 另外，经Carboxy-PTIO处理后产生的NO下游代谢产物，与单一的NO比较，抗病毒活性得以加强。

Electron paramagnetic resonance (EPR) spectroscopy has been used in a number of ways to study nitric oxide chemistry and biology. As an intrinsically stable and relatively unreactive diatomic free radical, the challenges for detecting this species ...

2017年7月4日 · In order to identify aqueous species formed in Plasma activated media (PAM), quantitative investigations of reactive oxygen and nitrogen species (ROS, RNS) were performed and compared to Milli-Q...

2007年5月15日 · Electron paramagnetic resonance (EPR) spin trapping is probably one of the best suitable platforms for development of new methods for quantification of biological NO. The most reliable EPR-based approaches developed so far are based on the reaction of NO with various iron complexes, both intrinsic and exogenously applied.

2011年12月1日 · By using the competitive NO-scavenging method between PTIO and antioxidants, we determined NO-scavenging capacity for biologically important hydrophilic antioxidants and the EPR method enabled rapid and reproducible determinations of NO-scavenging capacity.

2024年4月17日 · In this study, it is demonstrated that the addition of scandium triflate, Sc (OTf) 3 (OTf = OSO 2 CF 3), to an acetonitrile (MeCN) solution of PTIO • resulted in an electron-transfer disproportionation to generate the corresponding cation (PTIO +) and anion (PTIO −), the latter of which is suggested to be stabilized by Sc 3+ to form [ (PTIO)Sc] 2+.

通过EPR光谱分析了两种常用的NO疏水和亲水自旋阱，分别为Fe2 +（DETC）（2）和Fe2 +（MGD）（2）。 在冻结状态和室温下都记录了捕获的NO的EPR光谱以及现场位置标准。 我们介绍了上述顺磁性NO配合物的EPR光谱的详细表征，涉及g值，超精细分裂和线宽。 这项研究还提供了开发疏水和亲水水性介质中一氧化氮定量和灵敏检测系统所需的光谱数据。 通过EPR光谱分析了两种常用的NO疏水和亲水自旋阱，分别为Fe2 +（DETC）（2）和Fe2 +（MGD）（2）。 …

2003年12月19日 · We have generated electrochemically the oxidized and reduced forms of PTIO and carboxy-PTIO (C-PTIO), characterized their absorption spectra, and determined the reduction potentials for the oxoammonium/nitroxide and nitroxide/hydroxylamine couples.

1996年6月1日 · 电子顺磁共振（epr）光谱已用于检测自由基，包括一氧化氮（no）。 该方法用于评估类胡萝卜素（氧源性自由基的非特异性清除剂）是否可以还原另一种自由基，即NO。
