Controllable Hydrogen Sulfide Donors and the Activity Against Myocardial Ischemia-Reperfusion Injury #MMPMID23547844

Hydrogen sulfide (H2S), known as an important cellular signaling molecule, plays critical roles in many physiological and/or pathological processes. Modulation of H2S levels could have tremendous therapeutic value. However, the study on H2S has been hindered due to the lack of controllable H2S releasing agents which could mimic the slow and moderate H2S release in vivo. In this work we report the design, synthesis and biological evaluation of a new class of controllable H2S donors. Twenty five donors were prepared and tested. Their structures were based on a perthiol template, which was suggested to involve in H2S biosynthesis. H2S release mechanism from these donors was studied and proved to be thiol-dependent. We also developed a series of cell-based assays to access their H2S related activities. H9c2 cardiac myocytes were used in these experiments. We tested lead donors? cytotoxicity and confirmed their H2S production in cells. Finally we demonstrated that selected donors showed potent protective effects in an in vivo murine model of myocardial ischemia-reperfusion injury, through a H2S related mechanism.
