Used in research to study cardiovascular and pulmonary conditions, particularly for its role in activating soluble guanylate cyclase (sGC), an enzyme involved in regulating blood pressure and vascular tone. It shows potential in enhancing nitric oxide signaling, making it valuable in investigating treatments for pulmonary hypertension and heart failure. Also used as a pharmacological tool to explore cyclic GMP pathways in cellular and animal models. Not approved for clinical use; strictly for experimental research.
