Neuromedin U,a 23-amino acid brain-gut peptide, regulates several important physiological functions through its cognate receptor NMUR2 in the central nervous system, including energy balance, stress response, and nociception.
R-PSOP is a potent and selective nonpeptidic NMUR2 antagonist, exhibiting binding affinity to human and rat NMUR2 with Ki values of 52 nM and 32 nM, respectively. This compound demonstrates moderate central nervous system (CNS) penetration and is valuable in the study of eating disorders, obesity, pain, and stress-related disorders [1].
