in DMSO with electrophilic double bonds to afford Michael adducts (see scheme), whereas no trapping reaction takes place in apolar solvents. A simple and quick NMR spectroscopic method to identify Michael acceptors and sort them into reversible and irreversible thiol sinks is validated biologically in a cellular assay sensitive to thiol‐trapping agents. DMSO=dimethyl sulfoxide.
速度捕集剂:半胱胺在DMSO中与亲电子双键反应生成迈克尔加成物(参见方案),而在非极性溶剂中不发生捕集反应。在对硫醇捕集剂敏感的细胞测定中,通过生物学方法验证了一种简单,快速的NMR光谱法,可识别迈克尔受体并将其分类为可逆和不可逆的硫醇沉。DMSO =二甲基亚砜。
