A superoxide anion responsive and self-reporting fluorescent HS donor for the treatment of diabetic wound.

Superoxide anion (O) 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 (HS), recognized as a significant biological signaling molecule, plays vital roles in protecting mammalian cells from oxidative damage and promoting tissue regeneration.
