Abstract
S-nitrosothiols (RSNO), such as SNAP, GSNO, and Glc-SNAP-1 exhibited a single, totally irreversible, diffusion controlled reduction peak at potentials of -0.97 V, -0.98 V and -0.91 V, respectively, vs. Ag/AgCl (3 M NaCl) reference electrode. This corresponded to the nitric oxide (NO) release from the S-nitrosothiols. A possible mechanism is proposed for the reduction process.
摘要
S-亚硝基硫醇（RSNO），如SNAP、GSNO和Glc-SNAP-1，相对于Ag/AgCl（3M NaCl）参比电极，分别在-0.97V、-0.98V和-0.91V的电位下呈现出一个单一的、完全不可逆的、扩散控制的还原峰。这对应于S-亚硝基硫醇释放一氧化氮（NO）。针对该还原过程提出了一种可能的机制。
