Urotensin II is a somatostatin-like neuropeptide agonist of the urotensin II receptor (UTR; Ki = 2 nM).{7198} It increases intracellular calcium levels in a concentration-dependent manner in HEK293 cells expressing human UTR (EC50 = 0.6 nM). Urotensin II increases the level of reactive oxygen species (ROS) in pulmonary artery smooth muscle cells and induces proliferation, an effect that is inhibited by depletion of NADPH oxidase subunits.{36499} Urotensin II potently induces contraction of isolated rat thoracic aorta with an EC50 of 0.8 nM.{7198} It also induces contraction of isolated cynomolgus monkey arterial, but not venous, vessels and, when administered at doses greater than 100 pmol/kg, can lead to severe myocardial depression and fatal circulatory collapse.
