family of photoactivatable HNO donors of general structure RSO2NHO-PT [where PT represents the (3hydroxy-2-naphthalenyl)methyl (3,2-HMN) phototrigger] has been developed, which rapidly releases HNO. Photogeneration of HNO was demonstrated using the vitamin B12 derivative aquacobalamin as a trapping agent. The amount of sulfonate RSO2 produced was essentially the same as the amount of HNO released upon
已开发出一类新的可光活化 HNO 供体,其一般结构为 RSO2NHO-PT [其中 PT 代表 (3hydroxy-2-naphthalenyl)methyl (3,2-HMN) 光触发剂],可快速释放 HNO。使用维生素 B12 衍生物水钴胺作为捕集剂证明了 HNO 的光生成。产生的磺酸盐 RSO2 的量与光解时释放的 HNO 量基本相同,提供了一种间接量化 HNO 释放量的便捷方法。还观察到了两种竞争途径;涉及 O-N 键断裂导致磺胺释放的途径,以及导致母体 N-羟基磺酰胺 RSO2NHOH 释放的途径(对于
