Facile, two-step synthesis and kinetic characterization of new chemical probes for selective labeling of sulfenic acid (-SOH) in proteins are presented. The synthesis route relies on the simple and highly efficient Michael addition of thiol containing tags or linkers to 4-cyclopentene-1,3-dione, the unsaturated derivative of 1,3-cyclopentanedione.
介绍了用于选择性标记蛋白质中次磺酸 (-SOH) 的新型化学探针的简便、两步合成和动力学表征。合成路线依赖于简单高效的迈克尔加成,将含有标签或接头的硫醇添加到 4-环戊烯-1,3-二酮,即 1,3-环戊二酮的不饱和衍生物。
