  The reaction of <i>S</i>-nitrosothiols with thiols at high thiol concentration

  摘要：

  Reactions of S-nitrosothiols (RSNO) with their corresponding thiols (RSH) present in a large excess (>20-fold) proceed readily to give the disulfide. Ammonia is formed together with some nitrite anion, and these constitute >90% of the "nitrogen" products. This is in marked contrast with the reaction at low thiol concentration, where nitric oxide is the major initial "nitrogen" product, which is rapidly converted in the presence of oxygen in water to nitrite anion. Also in marked contrast to the "low thiol concentration" reaction, the reaction at high thiol concentration is not affected by added Cu2+, nor by the metal-ion scavenger EDTA. Kinetically all reactions were excellent first-order processes, and the reactions were also strictly first order in thiol concentration. A large range of nitrosothiols were studied and the generality of the reaction established. Some reactions of RSNO with other thiols (R'SH) were examined and the results readily interpreted in terms of a prior rapid equilibrium transnitrosation. The pH dependence for the reaction of S-nitrosocysteine with cysteine clearly showed that the reactive species is the cysteine thiolate anion. The results are discussed along with those of two other recent reports of these reactions, in terms of thiolate attack initially at the nitroso nitrogen atom, and subsequently at sulfur atoms, eliminating RSSR and yielding hydroxylamine, which is rapidly reduced by thiolate ion to ammonia. The results are also discussed in connection with the release of NO from nitrosothiols and with the important biological consequences, both for the in vivo reactions of NO and for the potential of nitrosothiols as NO-releasing drugs for medical use.

  Synthesis and kinetics of decomposition of some novel S-nitrosothiols

  摘要：

  S-亚硝基巯基物质2-乙酰胺基-2-脱氧-S-亚硝基-1-硫基-β-D-葡萄糖吡喃糖3,4,6-三乙酸酯（GPSNO）和S-亚硝基-N-氨基-D，L-青霉胺（SNCP）通过相应巯基的S-亚硝化反应合成，分离并进行了全面的表征。从1-巯基甘油中获得的亚硝基巯基物质（TGSNO）为红色胶状液体，在室温下迅速分解，因此没有进行表征。GPSNO的分解动力学表明存在一个令人惊讶的大热途径与Cu2+ / RS-催化反应重叠。结果强烈表明，产物二硫化物形成了Cu2+络合物（有一些光谱证据支持），从而导致了该途径的不完全转化。抗坏血酸也作为Cu2+还原剂。另一个S-亚硝基糖，S-亚硝基-1-硫基-β-D-葡萄糖（SNTG），从生成并现场使用的溶液中表现出非常相似的行为。TGSNO的分解显示出诱导期，表明慢速初始生成Cu+（真正的催化剂）正在发生。还存在一个显着的替代途径（类似于GPSNO发现的途径），其中速率似乎与[Cu2+]无关，但非常不寻常的是，该途径可以通过在反应开始时或稍后加入EDTA来有效地停止。提出了反应方案来解释这些异常的反应特性。关键词：S-亚硝基巯基物质，一氧化氮，抗坏血酸，铜催化。
