Abstract
Superoxide anion (O2•−) not only serves as a critical precursor for numerous damaging reactive oxygen species (ROS), but also is implicated in a variety of diseases, including cancer, cardiovascular disorders, and diabetes. Consequently, reducing the levels of superoxide anions and alleviating oxidative stress are of paramount importance. Conversely, hydrogen sulfide (H2S), recognized as a significant biological signaling molecule, plays vital roles in protecting mammalian cells from oxidative damage and promoting tissue regeneration. In this study, we reported a novel superoxide anion-responsive H2S donor (HSD-SO-B) designed to scavenge O2•− and produce H2S concurrently. This H2S donor exhibits several advantages: (1) rapid response to superoxide anions (O2•−) with remarkable selectivity over competing species (2) generating H2S while scavenging superoxide anions (3) producing ratiometric fluorescence for both visualization and quantification of H2S release. Moreover, this O2•−-responsive, self-immolative fluorescent H2S donor has shown significant therapeutic and reparative effects on the diabetic wound model in mice.
期刊介绍:
Free Radical Biology and Medicine is a leading journal in the field of redox biology, which is the study of the role of reactive oxygen species (ROS) and other oxidizing agents in biological systems. The journal serves as a premier forum for publishing innovative and groundbreaking research that explores the redox biology of health and disease, covering a wide range of topics and disciplines. Free Radical Biology and Medicine also commissions Special Issues that highlight recent advances in both basic and clinical research, with a particular emphasis on the mechanisms underlying altered metabolism and redox signaling. These Special Issues aim to provide a focused platform for the latest research in the field, fostering collaboration and knowledge exchange among researchers and clinicians.
