Method of synthesizing 1,3-cyclohexadione derived reagents useful for detection or isolation of sulfenic acid-containing compounds

摘要

The present invention provides a method of synthesizing compounds of Formula I:; wherein: R₁ is a label (e.g., a detectable groups; an anti-tumor agents); L is present or absent and when present is a linking group; and x represents an integer from 1 to 10; or a pharmaceutically acceptable salt thereof. the compounds are useful for, among other things, identifying cysteine sulfenic acids in proteins and monitoring oxidative damage in proteins and cells.
