4-(3-Tosyl-2-(tosylmethyl)propanoyl)benzoic acid (Bis-sulfone Acid) 是一种具游离羧酸和两个甲苯磺酰基的强共价连接体。每个甲苯磺酰基可通过迈克尔加成被硫醇或胺亲核试剂替代,并因含有两个甲苯磺酰基,该反应可进行两次。此功能可用于将两个还原态的半胱氨酸残基“钉合”于特定蛋白质上以重新形成二硫键。羧酸端可以自由反应生成酰胺或酯。

产品描述 | 4-(3-Tosyl-2-(tosylmethyl)propanoyl)benzoic acid, known as Bis-sulfone Acid, is a compound with strong covalent bonding properties featuring a free carboxylic acid and two tosyl groups. Each tosyl group has the potential to be replaced by thiol or amine nucleophiles through Michael addition, allowing this reaction to occur twice due to the presence of two tosyl groups. This facilitates the "stapling" of two reduced cysteine residues in a given protein to reform disulfide bonds. The carboxylic acid can also readily react to form amides or esters. |
