Used in research to deliver carbon monoxide to cells in a controlled manner. Carbon monoxide has signaling properties in biological systems and can influence inflammation, vascular tone, and cell death. CORM-3 is studied for its potential protective effects in conditions like ischemia-reperfusion injury, organ transplantation, and inflammatory diseases. It allows precise delivery without the risks of inhaling gaseous carbon monoxide. Commonly used in preclinical models to explore therapeutic benefits of CO in cardiovascular and immune-related disorders.
