Structure de la panarine Dihydratée, un Nouvel Alcaloïde Extrait d'un Curare Vénézuélien

The crystal structure of Panarine dihydrate was solved by direct methods. This new alkaloid has a conformation very similar to that of macusine A with a 3-alpha cis configuration. The positive charge on the quaternary nitrogen coexists with a negative charge on the carboxylate group. Molecules are linked together through van der Waals interactions and five hydrogen bonds involving water molecules.
