L-771688 hydrochloride 是一种强效且高度选择性的 α1A-肾上腺素受体拮抗剂 ((Kd=43-90 pM)。L-771688 hydrochloride 对克隆的人类、大鼠和狗α1A-肾上腺素受体表现出很高的亲和力 (Ki≤ 1 nM),与 α1B 和 α1D 亚型相比具有超过 500 倍的选择性。L-771688 有效地拮抗这些受体中的去甲肾上腺素诱导反应,并在大鼠、狗、人和猴模型中抑制由苯肾上腺素或 A-61603 诱导的收缩。

生物活性

L-771688 hydrochloride is a potent and highly selective α1A-adrenoceptor antagonist (Kd=43-90 pM). L-771688 hydrochloride is effective against cloned human, rat and dog α1A-adrenergic receptors. L-771688 exhibits high affinity (Ki ≤ 1 nM) and over 500-fold selectivity over the α1B and α1D isoforms. L-771688 potently antagonizes norepinephrine-induced responses at these receptors. Inhibits contractions induced by phenylephrine or A-61603 in rat, dog, human and monkey models[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
