Alternative Name: [Pen5,DTrp7,Orn8]hU-II(4-11)

Biological Activity

Selective and competitive urotensin-II (UT) receptor antagonist (pKB = 8.3). Blocks hU-II induced contractions in thoracic aorta ex vivo. Exhibits no effect on noradrenaline or endothelin 1-induced contraction or on acetylcholine-induced relaxation. Behaves as a partial agonist in a calcium mobilization assay (in CHO cells expressing hUT receptors).

Technical Data

DXFWXYCV(Modifications: X-2 = Pen, X-5 = Orn, Trp-4 = D-Trp, Disulfide bridge: 2-7)

Soluble to 2 mg/ml in water
Store at -20°C
