The present application relates to method of vaccinating a subject against infection by an enveloped virus. The method includes providing a compound of the Formula (I) as described herein, and contacting the compound of Formula (I) with an isolated enveloped virus, having a membrane, to inactivate the membrane of the isolated enveloped virus. The subject is then treated with the enveloped virus having an inactivated membrane to vaccinate the subject against the enveloped virus. Further disclosed is an ex vivo vaccine composition including the compound of Formula (I) and an enveloped virus.

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 that 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 be involved 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 rnyocytes were used M 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.
