H2S Donor 5a is a cysteine-activated hydrogen sulfide (H2S) donor. H2S Donor 5a is stable in aqueous buffers and regulates the rate of H2S generation. H2S Donor 5a does not react with potential cellular nucleophiles such as -OH and -NH2 groups. In the presence of cysteine, a time-dependent decomposition of the donors accompanied by H2S release was observed.
