Selective Synthesis and Biological Evaluation of Sulfate-Conjugated Resveratrol Metabolites
摘要:
Five resveratrol sulfate metabolites were synthesized and assessed for activities known to be mediated by resveratrol: inhibition of tumor necrosis factor (TNF)alpha induced NF kappa B activity, cylcooxygenases (COX-1 and COX-2), aromatase, nitric oxide production in endotoxin-stimulated macrophages, proliferation of KB or MCF7 cells, induction of quinone reductase I (QRI), accumulation in the sub-G, phase of the cell cycle, and quenching of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical. Two metabolites showed activity in these assays; the 3-sulfate exhibited QRI induction, DPPH free radical scavenging, and COX-1 and COX-2 inhibitory activities and the 4'-sulfate inhibited NF kappa B induction, as well as COX-1 and COX-2 activities. Resveratrol and its 3'-sulfate and 4-sulfate inhibit NO production by NO scavenging and down-regulation of iNOS expression in RAW 264.7 cells. Resveratrol sulfates displayed low antiproliferative activity and negligible uptake in MCF7 cells.

Starting from the commercially available natural product (E)-resveratrol (1), the four selectively tert-butyldimethylsilyl (TBS) protected (E)-resveratrols 6-9 were prepared by one reaction. Using 6-9 as glucosyl acceptors and trifluoroacetimidate 11 as glucosyl donor, three bioactive natural glucopyranoside conjugates of (E)-resveratrol 2-4 and one novel compound (5) were efficiently prepared in two steps.
resveratrol itself and decided to explore them as potential drugs for neurodegenerative and neurological diseases. We have also designed and prepared a series of O-silyl RES prodrugs to improve their bioavailability. We found that di-triethylsilyl and di-triisopropylsilyl RES derivatives were better in vitro neuroprotective and anti-inflammatory agents than RES. Among these derivatives and their corresponding
在食物中发现的天然酚类化合物已证明对多种病理具有有趣的预防和治疗作用。事实上,其中一些,例如白藜芦醇 (RES),已经在临床试验中进行了检查。然而,它们的成功很少,主要是因为它们的生物利用度低。在这项研究中,我们意外地发现O-甲硅烷基 RES 衍生物比白藜芦醇本身具有更好的神经保护活性,并决定探索它们作为治疗神经退行性疾病和神经系统疾病的潜在药物。我们还设计并制备了一系列O-甲硅烷基RES前药以提高其生物利用度。我们发现二三乙基甲硅烷基和二三异丙基甲硅烷基 RES 衍生物在体外效果更好神经保护剂和抗炎剂比 RES。在这些衍生物及其相应的酰基-、糖基-和氨基甲酰基-前药中,3,5-三乙基甲硅烷基-4'-(6″-辛酰基吡喃葡萄糖基)白藜芦醇26在斑马鱼胚胎中表现出最佳的毒性和神经保护活性。化合物26还能够以与 RES 类似的方式减少亨廷顿病 3-硝基丙酸小鼠模型中运动协调性的丧失。然而,与 RES

The present invention relates to the use of a compound of formula (I): in which R1, R2 and R3 independently denote: -a group of formula (II), or -a hydrogen atom H, it being understood that at least one of the radicals R1, R2, R3 denotes a group of formula (II); and also the salts thereof, the solvates thereof, and/or the isomers thereof, for prevent- ing and/or cosmetically treating the signs of skin aging.
Naturally reduced activity: The glucuronidation and reduction metabolites of resveratrol, a natural polyphenol in grapes and various other plants, show in vitro biologicalactivity similar to that of resveratrol. This supports the theory that they contribute to the in vivo biologicalactivity attributed to the parent molecule.

Improved resveratrolactivity: Glucosylated resveratrolprodrugs and resveratrolsulfatemetabolites show improved anti‐proliferative and anti‐angiogenic activity in comparison to resveratrol itself. These results suggest resveratrol derivatives as potential drugs and confirm that resveratrolsulfatemetabolites contribute to the in vivo biological activity observed for the parent compound.
