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...

Guanabenz is an alpha2-adrenergic receptor agonist (effective concentrations 10-100 nM) with hypotensive effects.
