  摘要：

  已经开发了在温和条件下使用包封的过氧化氢作为氧化剂对未保护的芳族伯胺进行区域选择性溴化和碘化的方法，其中溴化钾（KBr）和碘化钾（KI）分别用作溴化剂和碘化剂。加合物不仅显示出对位或邻位的区域选择性-异构体，但对单溴化反应也具有显着的化学选择性。还研究了将硫化物选择性氧化为亚砜和砜的方法，获得了所需产品的良好或优异的收率。发现乙酸是这些反应的选择溶剂。这种简单的方法代表了苯胺的氧化卤化和硫化物氧化为亚砜和砜的生态友好的替代途径。

  日期：2015.1

  discovery efforts toward Hsp90 C-terminal inhibition focus on novobiocin, an antibiotic that was transformed into an Hsp90 inhibitor. Based on structural information obtained during the development of novobiocin derivatives and molecular docking studies, scaffolds containing a biphenyl moiety in lieu of the coumarin ring present in novobiocin were identified as new Hsp90 C-terminal inhibitors. Structure–activity

  Hsp90 C端功能的调节代表了一种有前途的治疗方法，用于治疗癌症和神经退行性疾病。目前针对Hsp90 C末端抑制的药物发现工作集中在新霉素（一种转化为Hsp90抑制剂的抗生素）上。根据在开发新霉素衍生物和进行分子对接研究期间获得的结构信息，将含有联苯部分代替新霉素中存在的香豆素环的支架鉴定为新的Hsp90 C末端抑制剂。结构-活性关系研究产生了新的衍生物，它们以纳摩尔浓度抑制乳腺癌细胞系的增殖，这直接与Hsp90抑制作用相对应。
