| Research Abstract |
Complanadines, dimeric alkaloids in the lycodine class alkaloids, induce secretion of neurotrophic factors from 1321N1 cells, which promotes neuronal differentiation of PC-12 cells and enhances expression of mRNA for nerve growing factor (NGF). Because of the unique structure and interesting biological activities, we started synthetic studies for disclose the origin of biological activities. So far, we established a convenient synthetic route to (±)-lycodine by using Diels-Alder and intramolecular Mizoroki-Heck reactions. This strategy will be readily applicable to the total syntheses of related natural products including complanadines and synthetic analogues for structure-activity relationship studies.
