Synthetic hydrogen sulfide (H2S) donors are useful research tools as well as potential therapeutic agents. In this chapter, we report the detailed protocols for the synthesis and evaluation of a series of phosphorodithioate-based H2S donors. Fluorescence assays were used to determine H2S release from the donors in both aqueous buffers and in cultured cells. These donors were found to be slow-release donors, much like the well-known GYY4137. These donors also showed some protective effects against hydrogen peroxide (H2O2)-induced oxidative damage in myocytes.
