This invention relates to certain novel compounds and derivatives thereof, their synthesis, and their use as selective alpha 1b adrenergic receptor antagonists. These compounds display submicromolar affinity for the human alpha 1b adrenergic receptor subtype while displaying at least five-fold lower affinity for the human alpha 1d and alpha 1a adrenergic receptor subtypes, and many other G-protein coupled human receptors. One application of these compounds is in the treatment of hypertension. More specifically, these compounds display selectivity for lowering blood pressure without, for example, substantially affecting urethral pressure.
这项发明涉及某些新颖化合物及其衍生物,它们的合成以及它们作为选择性α1b肾上腺素能受体拮抗剂的用途。这些化合物在人类α1b肾上腺素能受体亚型上显示亚微摩尔级别的亲和力,同时对于人类α1d和α1a肾上腺素能受体亚型以及许多其他G蛋白偶联的人类受体的亲和力至少低五倍。这些化合物的一个应用是用于治疗高血压。更具体地说,这些化合物表现出降低血压的选择性,例如在不显著影响尿道压力的情况下。
