RXFP3/4 agonist 2（Cat No.:I044149）is a synthetic small-molecule agonist that selectively activates relaxin family peptide receptors 3 and 4 (RXFP3 and RXFP4), which are G-protein-coupled receptors involved in neuroendocrine signaling and energy homeostasis. RXFP3 is primarily expressed in the brain and regulates stress responses, feeding behavior, and arousal, while RXFP4 is associated with gastrointestinal function and metabolic regulation. RXFP3/4 agonist 2 is used in preclinical research to explore the physiological roles of these receptors and their potential as therapeutic targets for disorders such as obesity, anxiety, depression, and irritable bowel syndrome.
