Abstract

The present invention 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 also provides new, medically useful homodimeric and heterodimeric naphthylisoquinoline compounds and derivatives thereof.
