Used in research to study urotensin II receptor (UT) signaling pathways, particularly in cardiovascular and endocrine systems. Shows high selectivity for the UT receptor, making it a valuable tool for investigating receptor function and ligand interactions. Applied in assays to measure intracellular calcium mobilization and receptor binding affinity. Also utilized in animal studies exploring roles in vasoconstriction, hypertension, and metabolic regulation. Stable in biological environments due to trifluoroacetate salt form, suitable for in vitro and in vivo experiments.
