SR 48692 is primarily utilized in research settings to study the neurotensin receptor system. It acts as a selective antagonist for the neurotensin receptor 1 (NTS1), making it a valuable tool in understanding the role of neurotensin in various physiological and pathological processes. Researchers employ it to investigate its effects on dopamine modulation, which is relevant in studying psychiatric disorders such as schizophrenia and addiction. Additionally, it is used in exploring its potential role in cancer research, as neurotensin receptors are implicated in the growth and proliferation of certain tumor types. Its application in these areas helps advance the development of targeted therapies and enhances the understanding of receptor-mediated signaling pathways.
