alpha-yohimbine Usage And Synthesis

Uses

Rauwolscine is a selective α2-adrenoceptor antagonist that inhibits tumor growth and induces apoptosis[1].

Definition

ChEBI: Rauwolscine is a methyl 17-hydroxy-20xi-yohimban-16-carboxylate.

in vivo

Rauwolscine (0.5 mg/kg, daily) reduces tumor growth by enhancing apoptosis and reducing cell proliferation in Balb/c female virgin mice[1].
Rauwolscine (i.v., 2.24 mg/kg) can significantly release lick-shock conflict responding in rats similar to the α agonist clonidine (0.022 mg/kg) and the benzodiazepine diazepam (0.5 mg/kg) [2].
