Rauwolscine  (Synonyms: α-Yohimbine; Corynanthidine; Isoyohimbine)

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

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].
