SNAP 94847 hydrochloride is primarily utilized in neuroscience research due to its role as a selective antagonist for the melanin-concentrating hormone receptor 1 (MCH1). It is commonly employed in studies aimed at understanding the MCH1 receptor's function in regulating behaviors such as feeding, energy balance, and mood. Researchers use this compound to investigate its potential effects on appetite suppression and weight management, as MCH1 is implicated in these processes. Additionally, it serves as a valuable tool in exploring the receptor's involvement in stress responses, anxiety, and depression, providing insights into potential therapeutic targets for neuropsychiatric disorders. Its application extends to pharmacological studies to assess receptor binding affinity and downstream signaling pathways.
