Xylemin dihydrochloride is primarily utilized in the field of biomedical research, particularly in studies focusing on the nervous system. It is often employed as a selective antagonist for certain receptors, aiding in the investigation of neurotransmitter pathways and their roles in various physiological and pathological processes. This compound is instrumental in understanding the mechanisms underlying pain, inflammation, and neurodegenerative diseases. Additionally, it serves as a valuable tool in pharmacological experiments to evaluate the efficacy and specificity of new therapeutic agents targeting receptor-mediated responses. Its application extends to in vitro and in vivo models, providing insights that contribute to the development of potential treatments for neurological disorders.
