human α1a receptor

RS102895 hydrochloride 是一种CCR2拮抗剂，IC50值为 360 nM。

Fiduxosin 是一种具有选择性和有效性的 α1-adrenoceptor 拮抗剂，对 α1a-adrenoceptor，α1b-adrenoceptor 和 α1d-adrenoceptor 有抑制作用，Ki 值分别为 0.160 nM，24.9 nM 和 0.920 nM。Fiduxosin 可用于治疗良性前列腺增生。

DREADD agonist 21 是一种人毒蕈碱乙酰胆碱 M3 受体激动剂，EC50为 1.7 nM。

Desglymidodrine (ST 1059) 是一种选择性的 α1-肾上腺素受体 (α1-adrenoceptor) 激动剂，是 Midodrine 的活性代谢产物，是一种血管收缩剂，可用于研究心血管疾病和神经心源性晕厥。

Rec 15/2615 is an antagonist of α1B-adrenergic receptors (α1B-ARs; Ki = 0.45 nM for the recombinant human receptor).1 It selectively inhibits α1B-ARs over α1A-, α1D-, and α1L-ARs (Kis = 7.59, 10.23, and 49 nM, respectively). Rec 15/2615 inhibits norepinephrine-induced contractions of isolated rabbit prostate and urethral strips (Kis = 100 and 316.2 nM, respectively), as well as reduces norepinephrine-induced contractions of chloroethylclonidine-precontracted isolated rabbit aortic rings (Ki = 50 nM).2 It decreases diastolic blood pressure (ED25 = 183 μg/kg, i.v.) and increases intracavernous pressure in anesthetized dogs when administered intracavernously at doses ranging from 30 and 1,000 μg/kg.1,2 |1.

RS 504393 是一种高度选择性的 CCR2 趋化因子受体拮抗剂，作用于人重组 CCR2 和 CCR1 受体，IC50值分别为 89 nM 和大于 100 μM。

Conopeptide rho-TIA为从掠食性海螺Conus tulipa毒液中提炼的多肽，对人类α1B-Adrenergic Receptor呈现非竞争性抑制作用，同时对α1A-Adrenergic Receptor和α1D-Adrenergic Receptor表现出竞争性抑制。Conopeptide rho-TIA与这些亚型的结合特性可能对开发针对α1-Adrenergic Receptor亚型的选择性新药具有参考价值。
