Characterization and Biological Activity of a Hydrogen Sulfide-Releasing Red Light-Activated Ruthenium(II) Complex.

ABSTRACT: Hydrogen sulfide (H₂S) is a biological gasotransmitter that has been employed for the treatment of ischemia-reperfusion injury. Despite its therapeutic value, the implementation of this gaseous molecule for this purpose has required H₂S-releasing prodrugs for effective intracellular delivery. The majority of these prodrugs, however, spontaneously release H₂S via uncontrolled hydrolysis. Here, we describe a Ru(II)-based H₂S-releasing agent that can be activated selectively by red light irradiation. This compound operates in living cells, increasing intracellular H₂S concentration only upon irradiation with red light. Furthermore, the red light irradiation of this compound protects H9c2 cardiomyoblasts from an in vitro model of ischemia-
