Biological Activity
Ki: 12 nM (α2 adrenergic receptor)[1]
[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[1]. [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[2]. 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)[3]. 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) [4].

Structure
Ligand-specific conformational dynamics of the α2A-adrenergic receptor revealed by hydrogen-deuterium exchange mass spectrometry. [Abstract]2026 Mar 10:S0969-2126(26)00050-X. PMID: 41812653
Protocol
Fresh bovine frontal cortex is incubated in triplicate with [3H]Rauwolscine (82 Ci/mM, diluted). Incubation is terminated by filtration under reduced pressure over filters, which are then rinsed with ice cold Tris-HCl buffer, dried overnight and added to disposable glass minivials containing 3.0 mL of a 95% Econofluor/5% Protosol solution. Samples are counted by liquid scintillation spectrometry with an efficiency of 32%. (-)- [3H]Epinephrine binding to bovine cortex membranes is conducted at 25°C[1].
