Pricing Availability Delivery Time Qty
Cat.No. 2529 - UFP 803 | Asp-Pen-Phe-D-Trp-Dab-Tyr-Cys-Val (Disulfide bridge: 2 - 7) | CAS No. 879497-82-2
Description: Urotensin-II (UT) antagonist

Biological Activity

Urotensin-II (UT) receptor ligand; behaves as a silent antagonist in most in vitro assays and in vivo, but does retain small residual agonist activity under certain conditions in some assays. Competitively antagonizes U-II induced contractions in the rat aorta (pIC50 = 7.46) and prevents plasma extravasation elicited by U-II in mice in vivo.
