| | Raubasine Usage And Synthesis |
| Description | Vinca rosea L. yields this alkaloid which crystallizes as colourless needles from MeOH.
The base is laevorotatory having a specific rotation of [α]D_620 (MeOH) and forms
a crystalline hydrochloride, m.p. 281-3°e. The structure given above has been
elucidated from chemical and spectroscopic data. | | Uses | Antihypertensive, anti-ischemic. | | Uses | Antihypertensive, anti-ischemic (cerebral and peripheral) | | Definition | ChEBI: Ajmalicine is a monoterpenoid indole alkaloid with formula C21H24N2O3, isolated from several Rauvolfia and Catharanthus species. It is a selective alpha1-adrenoceptor antagonist used for the treatment of high blood pressure. It has a role as an antihypertensive agent, an alpha-adrenergic antagonist and a vasodilator agent. It is a monoterpenoid indole alkaloid, a methyl ester and an organic heteropentacyclic compound. It is a conjugate base of an ajmalicine(1+). | | target | P450 (e.g. CYP17) | | Purification Methods | It crystallises from MeOH, EtOH or EtOAc.
