  inhibitory activity, inhibits Heat shock protein 90 (HSP90) by binding weakly to a putative ATP-binding site within its C-terminus. To develop more potent HSP90 inhibitors that target this site and to define structure–activity relationships (SARs) for this class of compounds, we have synthesized twenty seven 3-amido-7-noviosylcoumarin analogues starting from NB and CA. These were evaluated for evidence of

  最近的研究表明，新霉素（NB）是具有证明的DNA回旋酶抑制作用的古默霉素（CA）家族的一种抗生素，通过与C-内的一个假定的ATP结合位点弱结合来抑制热休克蛋白90（HSP90）。总站。为了开发靶向该位点的更有效的HSP90抑制剂并定义此类化合物的结构-活性关系（SAR），我们合成了27种从NB和CA开始的3-amido-7-noviosylcoumarin类似物。使用几种生物学测定法评估了这些物质对HSP90抑制的证据，包括抑制细胞增殖和细胞周期阻滞，诱导热休克反应，抑制体外萤光素酶重新折叠以及消耗HSP90客户蛋白c-erbB-2 /。 HER-2 / neu（HER2）。这项SAR研究表明，通过除去NB / C-3上的吲哚-2-甲酰胺基团取代C-3上的4-羟基-异戊基苯甲酰胺基，可以显着提高生物活性。组从香豆素环。如化合物所示，香豆素部分中的4-羟基甲基化可适度提高生物活性11和13。
