It is selective for alpha2A-ARs over alpha2B- and alpha1-ARs (Kis = 1,949.83 and 13,300 nM, respectively), as well as over 40 receptors, ion channels, and transporters (IC50s = 540->10,000 nM). Atipamezole (0.04, 0.08, and 1.2...

Dexmedetomidine is the (S)-enantiomer of medetomidine, an imidazole compound that binds to alpha2-adrenoceptors (Ki = 1.08 nM) with high affinity and selectivity compared to that of alpha1-adrenoceptors (Ki = 1.8 µM). Dexmedetomidine produces analgesic, sedative, and anxiolytic effects through both presynaptic...

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...
