A one-step reductive ligation mediated disulfide formation of S-nitrosothiols was developed. This reaction involves the reaction of the S-nitroso group with phosphine-thioesters to form sulfenamide and thiolate intermediates, which then undergo a fast intermolecular disulfide formation to form stable conjugates. This reaction can be used to design new biosensors of S-nitrosated proteins.
开发了一种一步还原连接介导的 S-亚硝基硫醇的二硫键形成方法。该反应涉及 S-亚硝基基团与膦硫酯的反应,形成磺酰胺和硫醇中间体,然后快速进行分子间二硫键形成,形成稳定的缀合物。该反应可用于设计新的 S-硝化蛋白生物传感器。
