Description: SB 657510 is a selective urotensin-II (UT) receptor antagonist. SB-657510 inhibits U-II-induced intracellular Ca2+ mobilization (IC50 = 180 nM) and antagonizes the contractile action of U-II in isolated mammalian arteries and aortae (EC50 = 50 - 189 nM). SB-657510 dramatically blocked the UII-induced increase in adhesion between U937 and EA.hy926 cells. In addition, SB-657510 remarkably reduced UII-induced expression of TF in EA.hy926 cells. Taken together, our results demonstrate that the UII antagonist SB-657510 decreases the progression of inflammation induced by UII in endothelial cells.
