CYN 154806 is primarily utilized in neuroscience research due to its role as a selective antagonist for the somatostatin receptor subtype 5 (SSTR5). It is often employed in studies aimed at understanding the physiological and pathological functions of somatostatin receptors in the brain. Researchers use it to investigate the receptor's involvement in regulating hormone secretion, neuronal activity, and its potential implications in neurological disorders such as Alzheimer's disease and epilepsy. Additionally, CYN 154806 is applied in pharmacological experiments to explore the development of targeted therapies for conditions influenced by SSTR5 activity, including certain endocrine and metabolic disorders. Its specificity makes it a valuable tool for dissecting the complex signaling pathways mediated by somatostatin receptors.
