SB-706375 is a potent, selective nonpeptidic urotensin-II receptor (U-II) antagonist, potently inhibits [(125)I]hU-II binding to both mammalian recombinant UT receptors (Ki=4.7-20.7 nM at rodent, feline and primate recombinant UT receptors) and Ki 5.4 nM at the endogenous UT receptor in SJRH30 cells.

SB-706375 is a potent, competitive hU-II antagonist across species with pK(b) 7.29-8.00 in HEK293-UT receptor cells (inhibition of [Ca(2+)](i)-mobilization) and pK(b) 7.47 in rat isolated aorta (inhibition of contraction).
SB-706375 also reversed tone established in the rat aorta by prior exposure to hU-II (K(app) approximately 20 nM).
