Dobutamine hydrochloride is a synthetic catecholamine that acts on α1-AR, β1-AR, β2-AR (α-1, β-1 andβ-2 adrenoceptors). Dobutamine hydrochloride is a selective β1-AR agonist, relatively weak activity at α1-AR and β2-AR. Dobutamine hydrochloride can increase cardiac output and correct hypoperfusion.

Guanfacine hydrochloride is an orally active and blood-brain barrier permeability noradrenergic α2A agonist and has high selective for the α2A receptor subtype. Guanfacine has effects in producing hypotension and sedation. Guanfacine can be used for the research of a variety of prefrontal cortex (PFC) cognitive disorders, including tourette's syndrome and attention deficit hyperactivity disorder (ADHD).

Clonidine hydrochloride is an agonist of α2-adrenoceptor and potent antihypertensive agent.

Octopamine ((±)-p-Octopamine) hydrochloride, a biogenic monoamine structurally related to noradrenaline, acts as a neurohormone, a neuromodulator and a neurotransmitter in invertebrates. Octopamine hydrochloride can stimulate alpha2-adrenoceptors (ARs) in Chinese hamster ovary cells transfected with human alpha2-ARs. Octopamine hydrochloride increased glycogenolysis, glycolysis, oxygen uptake, gluconeogenesis and the portal perfusion pressure.

Methyldopa (L-(-)-α-Methyldopa), a potent antihyoertensive agent, is an alpha-adrenergic agonist (selective for α2-adrenergic receptors). Methyldopa is a proagent and is metabolized (α-Methylepinephrine) in the central nervous system.

Medetomidine hydrochloride is an orally active α2-adrenoceptor agonist (K_i: 1.08 nM). Medetomidine hydrochloride has sedative and analgesic effects. Medetomidine hydrochloride can cause peripheral vasoconstriction through the activation of α2 adrenoceptors on blood vessels.

Brimonidine (UK 14304) is a full α2-adrenergic receptor (α2-AR) agonist.

Norepinephrine (Levarterenol; L-Noradrenaline) tartrate is a potent adrenergic receptor (AR) agonist. Norepinephrine tartrate activates α₁, α₂, β₁ receptors.

Brimonidine tartrate (UK 14304 tartrate) is a full α2-adrenergic receptor (α2-AR) agonist.

Guanfacine is an orally active noradrenergic α2A agonist and has high selective for the α2A receptor subtype. Guanfacine has effects in producing hypotension and sedation. Guanfacine can be used for the research of a variety of prefrontal cortex (PFC) cognitive disorders, including tourette's syndrome and attention deficit hyperactivity disorder (ADHD).

Dobutamine is a synthetic catecholamine that acts on α1-AR, β1-AR, β2-AR (α-1, β-1 andβ-2 adrenoceptors). Dobutamine is a selective β1-AR agonist, relatively weak activity at α1-AR and β2-AR. Dobutamine can increase cardiac output and correct hypoperfusion.

A-61603 is a selective α₁A/α₁a-adrenergic receptor agonist with K_i of 8.89 nM for rat submaxillary gland α1A, K_i of 30.5 nM for cloned bovine α1a. A-61603 potentiates Ca²⁺ transients with EC₅₀ of 6.9 nM. A-61603 stimulates phosphoinositide hydrolysis, induces contractile responses in vas deferens, prostate strips, and spleen strips, and exhibits low activity in aortic rings. A-61603 can be used for research on adrenergic function.

LY 344864 is a selective, orally active 5-HT_1F receptor agonist with a K_i of 6 nM. LY 344864 is a full agonist producing an effect similar in magnitude to serotonin itself. LY 344864 can cross the blood brain barrier to some extent.
