Used primarily in biochemical research, this compound serves as a selective inhibitor of nitric oxide synthase (NOS). It is particularly valuable in studies aimed at understanding the role of nitric oxide in various physiological and pathological processes. Researchers utilize it to explore its effects on blood pressure regulation, immune response, and neurotransmission. Additionally, it aids in distinguishing between the different isoforms of NOS, helping to elucidate their specific functions in the body. Its application extends to investigating potential therapeutic strategies for conditions involving abnormal nitric oxide production, such as cardiovascular diseases, inflammation, and neurodegenerative disorders.
