Abstract

Hydrogen sulfide (H S) is a gaseous molecule that has received attention for its role in biological processes and therapeutic potential in diseases, such as ischemic reperfusion injury. Despite its clinical relevance, delivery of H S to biological systems is hampered by its toxicity at high concentrations. Herein, we report the first metal-based H S donor that delivers this gas selectively to hypoxic cells. We further show that H S release from this compound protects H9c2 rat cardiomyoblasts from an in vitro model of ischemic reperfusion injury. These results validate the utility of redox-activated metal complexes as hypoxia-selective H S-releasing agents for use as tools to study the role of this gaseous molecule in complex biological systems.
