合成了五种白藜芦醇硫酸盐代谢物,并评估了已知由白藜芦醇介导的活性:抑制肿瘤坏死因子(TNF)-α诱导NFκB活性、环加氧酶(考克斯-1和考克斯-2)、芳香化酶、内毒素刺激的巨噬细胞中的一氧化氮产生、KB或MCF 7细胞的增殖、醌还原酶1(QR 1)的诱导、在细胞周期的亚G1期的积累,和2,2-二苯基-1-苦基肼(DPPH)自由基的猝灭。在这些试验中,两种代谢产物显示出活性; 3-硫酸盐显示出QR 1诱导、DPPH自由基清除以及考克斯-1和考克斯-2抑制活性,4′-硫酸盐抑制NFκB诱导以及考克斯-1和考克斯-2活性。白藜芦醇及其3′-硫酸酯和4-硫酸酯通过清除NO和下调iNOS表达抑制RAW 264.7细胞NO生成。白藜芦醇硫酸盐显示低的抗增殖活性和可忽略不计的MCF 7细胞中的摄取。
Five resveratrol sulfate metabolites were synthesized and assessed for activities known to be mediated by resveratrol: inhibition of tumor necrosis factor (TNF)-α-induced NFκB activity, cylcooxygenases (COX-1 and COX-2), aromatase, nitric oxide production in endotoxin-stimulated macrophages, and proliferation of KB or MCF7 cells, induction of quinone reductase 1 (QR1), accumulation in the sub-G1 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 QR1 induction, DPPH free radical scavenging, and COX-1 and COX-2 inhibitory activities, and the 4′-sulfate inhibited NFκB induction, as well as COX-1 and COX-2 activities. Resveratrol, as well as 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.
