• Synthesis of 4′-ester analogs of resveratrol and their evaluation in malignant melanoma and pancreatic cell lines
  作者：Yong Wong、Gregory Osmond、Kenneth I. Brewer、Douglas S. Tyler、Merritt B. Andrus

  日期：2010.2

  4′-Ester analogs of the disease preventative agent resveratrol were synthesized and evaluated for their potential as anti-melanoma and pancreatic cancer agents. A decarbonylative Heck coupling was used to assemble the protected stilbene core structure. The 4′-acetate and the palmitoate analogs demonstrated selective activity with DM443 and DM738 cells over normal NHDF cells.

  合成了疾病预防剂白藜芦醇的4'-酯类似物，并评估了其作为抗黑素瘤和胰腺癌药物的潜力。使用脱羰Heck偶联剂组装受保护的二苯乙烯核结构。与正常的NHDF细胞相比，DM443和DM738细胞具有4'-乙酸和棕榈酸酯类似物的选择性活性。

  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

  设计，合成和评估了一系列31种白藜芦醇衍生物，以激活和抑制TRPA1通道。大部分充当白藜芦醇或异硫氰酸烯丙酯（AITC）等TRPA1通道的激活剂和脱敏剂。化合物4z（HUHS029）的抑制活性高于白藜芦醇，IC 50值为16.1μM 。通过全细胞膜片钳记录，在表达TRPA1的HEK293细胞以及大鼠背根神经节神经元中证实了4z对TRPA1的活性。此外，用4z预处理对体内AITC引起的TRPA1相关的疼痛行为表现出镇痛作用。

  The present invention includes methods for preparing resveratrol, resveratrol esters and substituted and unsubstituted stilbenes of the formula given below; where each Y is —O or halogen, each Z is —O or halogen, each n and each m is independently the value of 0, 1, 2, 3, 4 or 5, each A and each B is independently selected from P n , R or absent, each V and each W is independently selected from P n , straight or branched alkyl of from (2) to (6) carbon atoms and cycloalkyl of from (3) to (8) carbon atoms, alkoxy, phenyl, benzyl or halogen, R is independently selected from the group comprising alkyl with at least one carbon atom, aryl and aralkyl, P n is an alcohol protecting group and diastereoisomers of the foregoing. The compounds are made from a multi-step process including a N-heterocyclic carbon-type ligand coupling in the presence of a base with benzyol halide and styrene coupling partners. These compounds show increased stability for use in the food, cosmetic and pharmaceutical industries.

  日期：2009.3

  Αddition reactions of (1-methoxyalkyl)triphenylphosphonium ylides, derived from the corresponding Wittig salts and n-BuLi, to aldehydes were investigated. It was revealed that the betaine LiX complexes, the primary adducts, were converted to α-hydroxyketones, prior to the formation of oxaphosphetanes, by addition of aqueous NH4Cl at low temperature.

  研究了相应的Wittig盐和n -BuLi衍生的（1-甲氧基烷基）三苯基phosph基化物与醛的加成反应。揭示了在形成草酰膦烷之前，通过在低温下添加NH 4 Cl水溶液，将主要的加合物甜菜碱LiX配合物转化为α-羟基酮。
