Research use only, not for human use.

Rauwolscine, a natural alkaloid, is a specific and reversible α2-adrenergic receptor antagonist (Ki: 12 nM).

Rauwolscine, a natural alkaloid, is a specific and reversible α2-adrenergic receptor antagonist (Ki: 12 nM). It is a stereoisomer of yohimbine, which potently antagonizes both α1- and α2-adrenergic receptors. Rauwolscine also acts as a receptor antagonist at the serotonin 5-HT2B receptor (Ki: 14.3 nM) and as a weak partial agonist at 5-HT1A (IC50: 1.3 μM). The α2-adrenergic receptor has diverse physiological functions and antagonists like rauwolscine have numerous applications, including the modulation of mood and behavior.(In Vitro):[3H]Rauwolscine binding to α2 adrenergic receptor is reversible, stcreospccific, and saturable. [3H]Rauwolscine specifically labels both the high and low affinity states of the α2 adrenergic receptor in brain membranes. [3H]Rauwolscine also behaves as a 5-HT1A receptor agonist and this conclusion is compatible with earlier functional studies, indicating that rauwolscine (as well as yohimbine) has agonistic properties at the level of 5-HT autoreceptors. When using [3H]5-HT as a radioligand, rauwolscine is determined to have relatively high affinity for the human receptor (Ki human=14.3 nM, Ki rat=35.8 nM). Saturation studies shows that the affinity of [3H]Rauwolscine is similar in mouse, rat, rabbit, dog (2.33-3.03 nM) except man where it is significantly higher (0.98 nM) .
