Abstract

In continuing search for BChE-inhibitory compounds from Korean marine algae. we found a highly potent inhibitory activity in the methanolic extract of Sargassum species. After partition of the MeOH extract between $CHCl_3$ and 30% MeOH. the former layer was subjected to a series of ODS flash chromatography. silica column chromatography. and preparative TLC to afford three compounds (1-3). Detailed structural elucidation of them is in progress. Compound 1 showed potent BChE-inhibitory activity with $IC_{50}$ values of 11 ng/mL. (omitted)
