• Benzofurans from <i>Styrax agrestis</i> As Acetylcholinesterase Inhibitors: Structure–Activity Relationships and Molecular Modeling Studies

  An extract of Styrax agrestis fruits, collected in Vietnam, significantly inhibited acetylcholinesterase (AChE) in vitro. Bioassay-guided fractionation revealed three new egonol-type benzofurans: egonol-9(Z),12(Z) linoleate (1), 7-demethoxy-egonol-9(Z),12(Z) linoleate (2), and 7-demethoxyegonol oleate (4). Ten known egonol-type benzofurans were also isolated (3, 5, 6-13). In order to better understand structure activity relationships in this series, egonol derivatives 14-19 were prepared by chemical modifications and evaluated for their inhibition of AChE, butyrylcholinesterase (BChE), and AChE-induced A beta aggregation. Compounds 1-4 were the most potent inhibitors of the series, which exhibited inhibitory activity against AChE (IC50 1.4-3.1 mu M) and, for 1, A beta aggregation (77.6%). Molecular docking studies were also performed to investigate interaction of these compounds with the active site of AChE.

  Eighteen derivatives of egonol (A-R) were synthesized and evaluated for their antimicrobial activities against Staphylococcus aureus ATCC 29213, Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231 and Escherichia coli ATCC 8739 microorganisms comparing with egonol. The obtained data reported that compound B exhibited improved activities against all tested bacteria than egonol, others have shown different range of activities. (C) 2010 Elsevier Ltd.

  We herein report the general, versatile, and convenient method for the synthesis of 2-arly/alkyl-5-bromo-7-methoxy benzofurans from easily available o-Vanillin in five steps. These benzofurans was successfully converted into biological active natural products Egonol, Homoegonol, and analogous on applying Heck reaction using ethyl/methyl acrylate in the presence of palladium catalyst.
