Chemical oxidation of a series of sydnonimine derivatives followed by NO release was studied. Substances having alkylamine substituents in the position 3 were shown to be considerably more potent NO donors in comparison with those having alkyl or aralkyl substituents in the position 3. It was suggested that the effect is mainly due to lowering of the activation energy of NO release upon stabilization of the cation formed competitevely by the amino group.
研究人员对一系列西地那非亚胺衍生物进行了化学氧化,随后研究了氮氧化物的释放。结果表明,与在第 3 位上有烷基或芳烷基取代基的物质相比,在第 3 位上有烷基胺取代基的物质是更有效的 NO 给体。研究表明,这种效应主要是由于氨基竞争性地稳定了阳离子,从而降低了氮氧化物释放的活化能。
