Tyr-Somatostatin-14 is primarily used in research and medical applications due to its role in regulating the endocrine system. It is often employed in studies focused on understanding the mechanisms of hormone secretion, particularly for insulin and glucagon. This peptide is also utilized in the development of diagnostic tools for detecting hormonal imbalances and related disorders. Additionally, it has potential therapeutic applications in managing conditions like acromegaly and certain types of tumors, as it inhibits the release of growth hormone and other peptides. Its modified structure allows for enhanced stability and targeted action in experimental and clinical settings.
