Proposed mechanism of H2S release and breakdown of ATB-346. The release of H2S from ATB-346 occurs at a very low pace when the drug is dissolved in an aqueous solution. The rate of H2S release is enhanced in the presence of tissue or in the presence of reducing agents (dithiothreitol, l-cysteine, or glutathione).
