Romifidine is an alpha2-adrenergic receptor (alpha2-AR) agonist. Epidural administration of romifidine (50 µg/kg) induces antinociception and sedation in donkeys. It also induces bradycardia in horses when administered at doses ranging from 0.04 to 0.12 mg/kg. Formulations containing romifidine have been used as...

Dexmedetomidine is an agonist of alpha2-adrenergic receptors (alpha2-ARs). It selectively binds to alpha2-ARs over alpha1-ARs (Kis = 0.015 and 5 nM, respectively). In vivo, dexmedetomidine (50 µg/kg) prevents increases in cardiac troponin I (CTnI), a marker of myocardial injury, as well as reduces myocardial...

In 1X PBS, pH 7.4, with 0.09% sodium azide. Alpha-2-adrenergic receptors are members of the G protein-coupled receptor superfamily. They include 3 highly homologous subtypes: alpha2A, alpha2B, and alpha2C. These receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and from...

Xylazine is an agonist of alpha2-adrenergic receptors (Ki = 194 nM). It is an analog of clonidine, an alpha2-adrenergic receptor agonist used to reduce blood pressure. Xylazine is used for sedation, anesthesia, and analgesia in non-human mammals. This product is also available as an analytical reference standard...

Xylazine is an agonist of alpha2-adrenergic receptors (Ki = 194 nM). It is an analog of clonidine, an alpha2-adrenergic receptor agonist used to reduce blood pressure. Xylazine is used for sedation, anesthesia, and analgesia in non-human mammals. This product is also available as an analytical reference standard...

Levonordefrin is the (-)-enantiomer of nordefrin, a synthetic derivative of norepinephrine (Cay-16673), that acts as a vasoconstrictor. Levonordefrin (1-5 µg/kg) rapidly increases blood pressure and heart rate in anesthetized dogs and has a more potent effect on blood pressure than the dextronordefrin enantiomer. It...

Medetomidine is an agonist of alpha2-adrenergic receptors (alpha2-ARs, Ki = 1.08 nM). It is selective for alpha2-ARs over alpha1-ARs (Ki = 1,750 nM). Medetomidine induces sedation in dogs. Formulations containing medetomidine have been used as sedatives in veterinary medicine. This product is also available as an...

Yohimbine is a natural alkaloid that has highest affinity for alpha2-adrenergic receptors (pKis = 8.2, 8.7, and 9.6 for human alpha2A, alpha2B, and alpha2C, respectively), with antagonist activity at these receptors. It less potently antagonizes serotonin 5-HT1 receptors (pKis = 7.3, 6.8, and 7.6 for human HT1A,...

Moxonidine is an imidazoline 1 (I1) receptor agonist (Ki = 56 nM in a radioligand binding assay). It is also an agonist of the alpha2A-adrenergic receptor (alpha2A-AR, Ki = 150 nM in a radioligand binding assay). It is selective for I1 and alpha2A-AR receptors over alpha1-, alpha2B, and alpha2C-ARs (Kis = >30,000,...

Fendiline is an alpha2-adrenergic receptor antagonist (Kd = 2.6 µM) and an L-type calcium channel blocker (IC50 = 17 µM) well-known for its coronary vasodilator effects. Fendiline has recently been reported to inhibit K-Ras plasma membrane localization (IC50 = 9.64 µM), which prevents K-Ras signal transduction and...

Rilmenidine is an antihypertensive agent. It binds to imidazole receptors in bovine rostral ventrolateral medulla homogenates (Ki = 6.1 nM), as well as alpha2-adrenergic receptors in bovine prefrontal cortex homogenates (Ki = 87 nM). Rilmenidine induces hypotension and bradycardia in anesthetized rats (ED50s = 0.25...

Rauwolscine is a natural alkaloid that acts as a selective and reversible alpha2-adrenergic receptor antagonist (Ki = 12 nM). It is a stereoisomer of yohimbine, which potently antagonizes both alpha1- and alpha2-adrenergic receptors. Rauwolscine also acts as a receptor antagonist at the serotonin 5-HT2B receptor (Ki...
