  A novel class of (2E)-(2-oxo-1, 2-dihydro-3H-indol-3-ylidene)acetate derivatives were designed and synthesized as potent anti-proliferative agents. Most of these compounds showed potent anti-proliferative activity against some tumor cell lines, including SK-BR-3, MDA-MB-231, HCT-116, SW480, Ovcar-3, HL-60, Saos-2 and HepG2. Compounds 8c and 11h were identified as the most potent ones, while HL-60,

  设计并合成了一类新型的（2E）-（2-氧代-1，2-二氢-3 H-吲哚-3-亚烷基）乙酸酯衍生物，作为有效的抗增殖剂。这些化合物大多数对某些肿瘤细胞系（包括SK-BR-3，MDA-MB-231，HCT-116，SW480，Ovcar-3，HL-60，SAos-2和HepG2）显示出有效的抗增殖活性。化合物8c和11h被认为是最有效的化合物，而HL-60，HCT116和MDA-MB-231是最敏感的细胞系。机理研究表明，化合物8c通过抑制TrxR增强活性氧的水平，然后通过激活HCT116细胞中的凋亡蛋白，bax和Caspase 3来诱导凋亡。SAR的初步分析表明，双键和酯基的修饰对抗增殖活性有很大影响。我们的发现表明，值得进一步研究（2E）-（2-oxo-1，2-dihydro-3 H -indol-3-ylidene）acetate的抗肿瘤效力。

  A unified catalytic asymmetric (N+1) (N=4, 5) annulation reaction of oxindoles with bifunctional peroxides has been achieved in the presence of a chiral phase-transfer catalyst (PTC). This general strategy utilizes peroxides as unique bielectrophilic four- or five-atom synthons to participate in the C−C and the subsequent umpolung C−O bond-forming reactions with one-carbon unit nucleophiles, thus providing

  在手性相转移催化剂 (PTC) 的存在下，已经实现了羟吲哚与双官能过氧化物的统一催化不对称 ( N +1) ( N =4, 5) 环化反应。这种通用策略利用过氧化物作为独特的双亲电四原子或五原子合成子参与 C−C 和随后与单碳单元亲核试剂的 umpolung C−O 键形成反应，从而提供了一种独特的方法来获得有价值的手性螺吲哚-四氢呋喃和-四氢吡喃在温和条件下具有良好的产率和高对映选择性。进行 DFT 计算以合理化高对映选择性的起源。还证明了所得产物的克级合成和合成效用。

  junctions into the underlying tissue. The initial rolling step is mediated by the interaction of leukocyte glycoproteins containing active moieties such as sialyl Lewisx (sLex) with P-selectin expressed on endothelial cells. Consequently, inhibition of this interaction by means of a small molecule P-selectin antagonist is an attractive strategy for the treatment of inflammatory diseases such as arthritis

  白细胞炎症和组织损伤部位的募集涉及白细胞沿内皮壁滚动，然后白细胞牢固粘附，最后白细胞跨细胞连接转运到下面的组织中。初始滚动步骤由包含活性部分的白细胞糖蛋白（如唾液酸化的Lewisx（sLex））与在内皮细胞上表达的P-选择蛋白的相互作用介导。因此，借助于小分子P-选择蛋白拮抗剂抑制这种相互作用是治疗炎性疾病如关节炎的有吸引力的策略。惠氏化学文库的高通量筛选确定了喹啉水杨酸类化合物（1）作为P-选择素的拮抗剂，其体外和基于细胞的测定方法的功效远远优于sLex。通过迭代药物化学，我们鉴定出具有改善的P-选择素活性，减少的二氢Orate脱氢酶抑制作用和可接受的CYP谱的类似物。铅化合物36在类风湿关节炎的大鼠AIA模型中有效。
