Chemical Properties:
  1. Rauwolscine hydrochloride is isolated as the oxalate from the leaf extract of Rauwolfia canescens L. from which the free base may be obtained as colourless needles which are laevorotatory with [α]30D – 40° (EtOH). The alkaloid forms crystalline salts: the hydrochloride, m.p. 27S-2S00C (dec.); [α]30D + 74° (H20); nitrate, m.p. 257-SoC (dec.); oxalate, m.p. 245-6°C and the picrate, m.p. 20SoC. Two active hydrogens are present and the alkaloid furnishes a monoacetyl derivative, m.p. 2l6-SoC (dec.).
  2. Rauwolscine hydrochloride with concentrated ammonia solution at room temperature converts the base into rauwolscinic acid, C2oH2403N2.H20, m.p. 262-4°C (dec.); [α]23D + l36.So (H20) which yields a crystalline hydrochloride, m.p. 255.5-257.5°C (dec.) and on esterification with MeOH reverts to the original alkaloid. On distillation with Zn dust, rauwolscine yields harman, 2-methylindole (skatole) and isoquinoline.
    Chakravarti has shown that the alkaloid is a cardiovascular depressant, shows hypotensive activity and is relatively highly toxic.
  1. Rauwolscine hydrochloride standard α 2 -adrenergic antagonist (K i values are 3.5, 4.6 , and 0.6 nM at cloned human α 2A , α 2B , and α 2C -adrenoceptors respectively). Partial agonist at 5-HT 1A receptors. Also available as part of the α 2 -Adrenoceptor Tocriset™ .
