Apraclonidine (ALO 2145) dihydrochloride is a selective α2 and weak α1 receptor agonist that effectively reduces intraocular pressure (IOP) in the eyes. It is available as a topical ophthalmic solution [1] [2].

Phentolamine mesylate (Phentolamine methanesulfonate) 是一种非选择性的、可逆的，具有口服活性的 α1 和 α2 肾上腺素能受体阻滞剂，能够扩张使血管，降低周围血管阻力。它可用于研究嗜铬细胞瘤相关的高血压，心力衰竭和勃起功能障碍。

Unifiram 是一种认知增强剂。 Unifiram 诱导大鼠海马 CA1 区场兴奋性突触后电位 (fEPSP) 幅度的持久增加 (EC50= 27 nM) 并增加大鼠大脑皮层中乙酰胆碱 (ACh) 的释放。

L-654284为一种α2-肾上腺素受体拮抗剂，展现出较高的选择性。该化合物在体外实验中与3H-clonidine及3H-rauwolscine的结合发生竞争，展示Ki值分别为0.8 nM和1.1 nM。在体内实验中，L-654284能显著提升大鼠脑皮层中的去甲肾上腺素周转率，表明其在中枢神经系统中对α2-肾上腺素受体具有阻断作用。此外，L-654284还能阻断克隆尼定在大鼠孤立输精管中的作用，其pA2值达到9.1。在α2与α1肾上腺素受体的选择性上，L-654284对3H-prazosin的结合抑制表现出Ki值为110 nM。

Napamezole is an α2 adrenergic receptor antagonist. Napamezole antagonizes methoxamine-induced contractions (alpha-1) of the rat vas deferens with a Kb of 135 nM. Napamezole reverses clonidine-induced decreased in twitch height in the electrically stimula

Moxonidine Hydrochloride is a selective agonist at the imidazoline receptor subtype 1, used as antihypertensive agent. Target: I1-R Moxonidine Hydrochloride is a centrally acting antihypertensive agent. Mixed Nischarin (I1 imidazoline receptor) and α2-AR (adrenergic) agonist; displays 40-fold higher affinity for I1 receptors versus α2-adrenoceptors. Moxonidine reduced stimulated NE overflow (log EC50: -6.15 + - 0.14). AGN192403, a selective ligand at I1-R, had no influence on the dose-response curve of moxonidine (log EC50: -6.01 + - 0.25). The hypotensive and bradycardic actions of moxonidine but not clonidine are mediated through imidazoline receptors and are dependent on intact noradrenergic pathways within the RVLM. Furthermore, the noradrenergic innervation may be associated with a 42 kDa imidazoline receptor protein.

The alpha-adrenoceptors blocking effect of (N-piperidinomethyl)-2-chromanne was studied in vivo and in vitro in the rat. In the pithed rat, (N-piperidinomethyl)-2-chromanne (1 mg kg i.v.) antagonized the pressor effects induced by alpha agonists. (N-piperidinomethyl)-2-chromanne competitively antagonized the pressor effects of M7 (alpha 2-agonist) and cirazoline (alpha 1-agonist). (N-piperidinomethyl)-2-chromanne antagonized the inhibitory effects of clonidine on presynaptic alpha 2-receptors in stimulated pithed rats.

Wy 27127 is an alpha 2-adrenoceptors antagonist that has estimated potency based on ability to block clonidine-induced inhibition of electrically-evoked contractions of the rat isolated vas deferens.
