Used extensively in research to study the role of nitric oxide in physiological and pathological processes. It acts as a competitive inhibitor of nitric oxide synthase, helping to understand its function in vascular tone, neurotransmission, and immune response. Commonly applied in experimental models to induce hypertension or investigate cardiovascular diseases. Also utilized in neuroscience to explore the impact of nitric oxide on brain function and behavior. Its inhibitory properties make it valuable in pharmacological studies targeting nitric oxide pathways.
