Patent

CA 2195647

The present invention provides methods of preparing monomeric naphthylisoquinoline alkaloids, including the antiparasitic korupensamines and related compounds, as well as non-korupensamines and other monomeric naphthylisoquinoline alkaloids. The present invention also provides methods of preparing dimeric naphthylisoquinoline alkaloids by coupling together two monomeric naphthylisoquinoline alkaloids, each of which may be the same or different, and one, both, or neither of which may possess a C-8' to C-5 naphthalene/isoquinoline linkage, to form homodimers or heterodimers, including the antiviral michellamines. The present invention further provides new, medically useful monomeric naphthylisoquinoline compounds and homodimeric and heterodimeric naphthylisoquinoline compounds and derivatives thereof.

L'invention concerne des procédés de préparation d'alcaloïdes monomère de naphthylisoquinoléine, dont les korupensamines antiparasitaires et des composés apparentés, ainsi que de produits autres que des korupensamines et d'autres alcaloïdes monomère de naphthylisoquinoléine. Elle concerne également des procédés de préparation d'alcaloïdes dimère de naphthylisoquinoléine par couplage de deux alcaloïdes monomère de naphthylisoquinoléine, dont chacun peut être semblable ou différent et dont l'un, les deux ou aucun des deux peut posséder une liaison C-8' à C-5 naphtalène/isoquinoléine, pour former des homodimères ou des hétérodimères, dont les michellamines antivirales. Elle concerne, de plus, de nouveaux composés monomères de naphthylisoquinoléine, ainsi que de nouveaux composés homodimères et hétérodimères de naphthylisoquinoléine et leurs dérivés médicalement efficaces.
