physiological conditions, the persulfide prodrug can be activated by an esterase to generate a “hydroxymethyl persulfide” intermediate, which rapidly collapses to form a defined persulfide. Such persulfide prodrugs can be used either as chemical tools to study persulfide chemistry and biology or for future development as H2S‐based therapeutic reagents. Using the persulfide prodrugs developed in this study, the

situ. Here, we report the synthesis of esterase-activated perthiocarbonate persulfide donors and investigate the effects of structural modifications on persulfide release. Although stericbulk of the ester did not significantly alter persulfide release kinetics, increased stericbulk of the thiol increased the persulfide release rate. In addition, we found that the stericbulk and identity of the thiol
