| SECURININE Usage And Synthesis |
| Description | A constituent of the leaves of Securinega suffructicosa Rehd., the base also occurs in Phyllanthus disco ides. It is obtained as yellow crystals and is strongly laevorotatory having [α]20D - 1106°(CHC13), [α]30D - 1106°(CHC13) and[α]20D - 1042° (c 1.0, EtOH). The alkaloid yields a crystalline methiodide, m.p. 235-6°C. | | Chemical Properties | Yellow Solid | | Uses | Extracted from leaves and roots of Securinega suffruticosa Rehder. The most widely studied of these alkaloids, Securinine, is a specific GABA receptor antagonist and has been found to have significant in vivo CNS activity. | | Uses | GABAA receptor blocker, CNS stimulant | | References | Murav'eva, Ban'kovskii., Dokl.
