Palosuran (ACT-058362) is a new potent and specific antagonist of the human UT receptor with an IC50 of 3.6±0.2 nM.

Palosuran hydrochloride (ACT-058362 hydrochloride) is a potent, selective, and orally active antagonist of urotensin II receptor, with an IC50 of 3.6 nM for CHO cell membranes expressing human recombinant receptors. Palosuran hydrochloride can improves pancreatic and renal function in diabetic rats.

[Orn5]-URP is a potent and selective pure antagonist of Urotensin-II receptor (UT), with an pEC50 of 7.24. [Orn5]-URP displays no agonist activity.

UFP-803 is a potent urotensin-II receptor (UT) ligand. UFP-803 has lower residual agonist activity, so it may be an important tool for the investigations on the role played by the UT system in physiology and pathology.

[Orn5]-URP TFA is a potent and selective pure antagonist of Urotensin-II receptor (UT), with an pEC50 of 7.24. [Orn5]-URP TFA displays no agonist activity.

UFP-803 TFA is a potent urotensin-II receptor (UT) ligand. UFP-803 TFA has lower residual agonist activity, so it may be an important tool for the investigations on the role played by the UT system in physiology and pathology.

SB-611812 is a urotensin II receptor (UTR) antagonist with the potential in the treatment of cardiovascular disease.
