  Synthesis and protein-tyrosine kinase inhibitory activity of polyhydroxylated stilbene analogs of piceatannol

  摘要：

  A series of hydroxylated trans-stilbenes related to the antileukemic natural product trans-3,3',4,5'-tetrahydroxystilbene (piceatannol) (1) has been prepared and tested for inhibition of the lymphoid cell lineage-specific protein-tyrosine kinase p56lck, which plays an important role in lymphocyte proliferation and immune function. A number of the analogues displayed enhanced enzyme inhibitory activity relative to the natural product. Reduction of the double bond bridging the two aromatic rings and benzylation of the phenolic hydroxyl groups was found to decrease activity significantly. The most potent compounds in the series proved to be trans-3,3',5,5'-tetrahydroxystilbene, trans-3,3',5-trihydroxystilbene, and trans-3,4,4'-trihydroxystilbene.

• Syntheses of Resveratrol and its Hydroxylated Derivatives as Radical Scavenger and Tyrosinase Inhibitor
  作者：Hyun-Suck Lee、Byung-Won Lee、Mi-Ran Kim、Jong-Gab Jun

  Eight hydroxylated stilbene derivatives including resveratrol, desoxyrhapontigenin and piceatannol as potential radical scavenger and tyrosinase inhibitor are synthesized using optimized Wittig-Horner reaction for excellent trans-selectivity in good yields. Antioxidant activity was tested against ABTS radical and tyrosinase inhibitory activity was performed with L-tyrosine as the substrate based on previous procedure with some modification. In general, catecholic stilbenes showed stronger activity against ABTS radical and resorcinolic moiety showed stronger tyrosinase inhibitory activity. Synthetic piceatannol which containing both catecholic and resorcinolic moieties showed the strongest activity in both as ABTS radical scavenger and tyrosinase inhibitor with $IC_50}$ values of 4.1 and $8.6\;\mu}M$, respectively.

  通过优化的Wittig-Horner反应合成了八种含羟基的二苯乙烯衍生物，包括白藜芦醇、去氧大黄素和松柏苷，这些化合物具有潜在的自由基清除和酪氨酸酶抑制作用，并表现出优异的反式选择性，产率良好。抗氧化活性针对ABTS自由基进行了测试，酪氨酸酶抑制活性则以L-酪氨酸为底物，参考先前的方法并进行了一些修改。总体而言，含儿茶酚基团的二苯乙烯对ABTS自由基显示出更强的活性，而含间苯二酚基团的化合物则表现出更强的酪氨酸酶抑制活性。合成的松柏苷同时含有儿茶酚和间苯二酚基团，在ABTS自由基清除和酪氨酸酶抑制方面显示出最强的活性，其$IC_50}$值分别为4.1和$8.6\;\mu}M$。

  New chiral phosphorus–olefin hybrid ligands derived from the rigid “privileged” l‐proline have been conveniently prepared and applied in the rhodium‐catalyzed asymmetric arylation of electron‐deficient olefins with arylboronic acids at room temperature; this reaction provides the desired products in excellent yields and high enantioselectivities. The origin of observed stereoselectivity has been investigated

  anti-inflammatory activities of these compounds were investigated. All compounds showed better antioxidant activity than resveratrol in ABTS assay. As for the anti-inflammatory test, 5 and 7 exhibited better activity than resveratrol. It is worth noting that nitrogen substitution on the extended aromatic resveratrol analogues has a significant impact on cell viability. Taking the antioxidant activities and NO

  由于白藜芦醇 ( 1 ) 已被证明具有抗氧化活性和抗病能力，因此对白藜芦醇 ( 1 ) 的研究已经进行了很长时间。还做出了许多努力来增加这些生物效应。在本研究中，六种新的扩展芳香族白藜芦醇类似物含有萘 ( 2 ) 及其生物电子等排体喹啉 ( 3和4 )、异喹啉 ( 5 ) 喹喔啉 ( 6 ) 和喹唑啉 ( 7 )) 支架是使用环化策略设计和合成的。研究了这些化合物的抗氧化和抗炎活性。所有化合物在 ABTS 测定中均显示出比白藜芦醇更好的抗氧化活性。至于抗炎测试，5和7表现出比白藜芦醇更好的活性。值得注意的是，扩展的芳香族白藜芦醇类似物上的氮取代对细胞活力有显着影响。考虑到抗氧化活性和 NO 抑制活性，我们得出结论，异喹啉类似物5可能有资格进行抗氧化和抗炎治疗的进一步研究。此外，我们的研究结果表明，为了提高多酚化合物的生物活性，延长芳香性和氮取代策略可能是设计未来候选药物的可行方法。
