The present invention provides methods of forming hydrogen sulfide. The methods include contacting a precursor compound with an unmasking agent; wherein the precursor compound comprises a hydrogen sulfide releasing moiety and a masked nucleophile; and wherein the contacting is conducted under conditions sufficient for cyclization of the precursor compound via lactone or lactam formation; thereby releasing hydrogen sulfide from the precursor compound. Hydrogen sulfide precursor compounds according to Formula (I) are also described, as well as methods for treating diseases and conditions using hydrogen sulfide precursors.

A general strategy of delivering hydrogenpersulfide (H2S2) is described herein. Esterase- and phosphatase-sensitive H2S2 prodrugs with tunable release rates have been synthesized. Their utility is validated in examining protein S-persulfidation. With this unique approach of directly delivering H2S2, our findings reaffirmed that S-persulfidation leads to decreased activity of glyceraldehyde 3-phosphate
