kinetic stabilizer, using fibril inhibition potency and plasma TTR bindingselectivity data. Herein, we have successfully employed a substructure combination strategy to use these data to develop potent and selective TTR kinetic stabilizers that rescue cells from the cytotoxic effects of TTR amyloidogenesis. Of the 92 stilbene and dihydrostilbene analogues synthesized, nearly all potently inhibit TTR

A series of 31 resveratrol derivatives was designed, synthesized and evaluated for activation and inhibition of the TRPA1 channel. Most acted as activators and desensitizers of TRPA1 channels like resveratrol or allyl isothiocyanate (AITC). Compound 4z (HUHS029) exhibited higher inhibitory activity than resveratrol with an IC50 value of 16.1 μM. The activity of 4z on TRPA1 was confirmed in TRPA1-expressing

The regioselective oxidative cross-coupling reactions of two different stilbene precursors catalyzed by FeCl3 or horseradish peroxidase-H2O2 in acetone solvent produced three dihydrobenzofuran-type heterodimers. The reductive debrominations of these cross-coupled dimers synthesized two heterodimers of resveratrol and isorhapontigenin, an analogue of (±)-scirpusin A and (±)-gnetuhainin Q.
FeCl 3或辣根过氧化物酶-H 2 O 2在丙酮溶剂中催化的两种不同的二苯乙烯前体的区域选择性氧化交叉偶联反应产生了三种二氢苯并呋喃型异二聚体。这些交叉偶联的二聚体的还原脱溴反应合成了白藜芦醇和异皂甙元的两个异二聚体,这是(±)-scirpusin A和(±)-gnetuhainin Q的类似物。

systems produced several coupling intermediates bearing distinct dimeric skeletons with moderate yields. The subsequent deprotection reactions of brominated coupling products achieved the efficient synthesis of natural products (±)-ε-viniferin, (±)-ampelosin B, and (±)-gnetins F, as well as an unnatural oligostilbene. The coupling mechanisms for the formation of different dimeric structures were also

The simple synthesis of (±)-parthenostilbenins A and B and (±)-quadrangularins A and B, as well as several unnatural resveratrol dimers, was successfully accomplished for the first time. Moreover, (±)-restrytisols B, (±)-leachianols F and G were efficiently prepared with higher yields compared with those in the literatures. The regioselective oxidative coupling reactions of 3,5-dibromo-resveratrol
