Abstract
Four new benzofuran derivatives, ribisin A (1), ribisin B (2), ribisin C (3), and ribisin D (4), were isolated from the MeOH extract of the fruiting bodies of Phellinus ribis. Their structures including their absolute configurations were determined by NMR and CD exciton chirality methods. Compounds 1–4
were found to promote neurite outgrowth in NGF-mediated PC12 cells at
concentrations ranging from 1 to 30 μM. The structure–activity
relationships of these compounds are also discussed.
