To improve the current understanding of the role of stilbenoids in the management of diabetes, the inhibition of the pancreaticα-amylase by resveratrol derivatives was investigated. To approach in a systematic way, the mechanistic and structural aspects of the interaction, potential bioactive agents were prepared as single molecules, that were used for the biological evaluation of the determinants

A series of hydroxystilbenes, analogues of the bioactive phytoalexin resveratrol, were synthesized and submitted to the catalytic action of a laccase from Trametes pubescens in a biphasic system made of ethyl acetate and acetate buffer. Oxidation took place at the 4′-hydroxy (4-hydroxy) position of the hydroxystilbenic moieties, followed by radical-radical coupling dimerization reactions. Most of the

Chemo-enzymatic synthesis of (<i>E</i>)-2,3-diaryl-5-styryl-<i>trans</i>-2,3-dihydrobenzofuran-based scaffolds and their <i>in vitro</i> and <i>in silico</i> evaluation as a novel sub-family of potential allosteric modulators of the 90 kDa heat shock protein (Hsp90)
considering their structural analogies to previously reported allostericmodulators, the sixteen new compounds synthesized in this work were tested in vitro for their potential stimulatory action on the ATPase activity of the molecular chaperone Hsp90. Combining experimental and computational results, we propose a mechanism of action for these compounds, and expand the structure–activity relationship (SAR) information
Comparative analysis of stilbene and benzofuran neolignan derivatives as acetylcholinesterase inhibitors with neuroprotective and anti-inflammatory activities
Stilbenes and benzofuran neolignans are important groups of plant phenolics therefore they play a significant role in plants and human health. The objective of this study was to investigate the structure-activity relationships of naturally occurring stilbene and benzofuran neolignan derivatives as acetylcholinesterase inhibitors. A series of these compounds were prepared and assessed for their inhibition
