Abstract/OtherAbstract:
We have developed an improved synthesis for the cell-permeable, sulfenic acid probe DAz-1. Using DAz-1, we detect sulfenic acid modifications in the cell-cycle regulatory phosphatase Cdc25A. In addition, we show that DAz-1 has superior potency in cells compared to a biotinylated derivative. Collectively, these findings set the stage for the development of activity-based inhibitors of Cdc25 cell-cycle phosphatases, which are sensitive to the redox state of the active-site cysteine and demonstrate the advantage of bioorthogonal conjugation methods to detect protein sulfenic acids in cells.
