progenitors in common use. Here, we report that appropriately substituted C-nitroso compounds act solely as donors of neutral nitric oxide through a first-order homolytic C−N bond scission to release up to 88% nitric oxide in DMSO at 25 °C. The reaction produces a carbon radical, and the yield of nitric oxide is dependent on the availability of radical traps. C-Nitroso compounds are sources of biologically
一氧化氮(NO)的生物活性的完整理解因其各种物种的不同反应谱以及通常使用的NO祖细胞通常复杂的分解行为而变得复杂。在这里,我们报道适当取代的C-亚硝基化合物仅通过一级均相C-N键断裂而充当中性一氧化氮的供体,从而在25°C的DMSO中释放高达88%的一氧化氮。该反应产生碳自由基,一氧化氮的产率取决于自由基陷阱的可用性。C-亚硝基化合物是具有生物活性的中性NO的来源,在兔主动脉环测定中显示出强大的NO生物活性。
