Urantide acetate(669089-53-6 free base) 是一种选择性和竞争性的 urotensin-II (UT) 受体拮抗剂 (pKB = 8.3)。体外阻断 hU-II 诱导的胸主动脉收缩。对去甲肾上腺素或内皮素 1 诱导的收缩或乙酰胆碱诱导的松弛没有影响。在钙动员测定（在表达 hUT 受体的 CHO 细胞中）中表现为部分激动剂。

Urantide acetate is a 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).
