  Isoquinolinamine derivatives had greater affinity for topo I than for topo II. Topo inhibition by 3,4-diarylisoquinolines was further supported by docking models showing intercalative and/or H-bond interactions between these compounds and the DNA/topo(s). An analysis of the correlation between the cytotoxicity and topo inhibition of these compounds indicated that the primary biological target of derivatives with

  受到单芳基异喹啉的初步成功的启发，并寻求寻找具有拓扑异构酶（拓扑）抑制活性的更有效和选择性的抗癌药，设计并合成了一系列二芳基异喹啉（3,4-二芳基异喹啉酮和3,4-二芳基异喹啉胺）。这些化合物的合成主要涉及锂化甲苯酰胺-苄腈的环加成，Suzuki偶联和亲核芳族取代反应。其中八种衍生物对人乳腺导管上皮肿瘤细胞（T47D），人前列腺癌细胞（DU145）和人结肠直肠腺癌细胞（HCT-15）有选择性毒性，但对正常人乳腺上皮细胞（MCF10A）没有影响。二芳基异喹啉化合物的拓扑抑制活性相对取决于它们的化学结构。3，4-二芳基异喹诺酮类通常不抑制topo I，而仅表现出对topo II的中等抑制作用。相反，几种3,4-二芳基异喹啉胺显示出优异的topo I抑制活性。异喹啉胺衍生物对topo I的亲和力大于对topo II的亲和力。对接模型进一步支持了3,4-二芳基异喹啉对拓扑的抑制作用，该模型显示了这些化合物与DNA

Notably, each member of the homologous series of amides Ph(CH2)nCONMe2 gives rise to a substantially different product: when n= 0, the reaction is normal, and the yield of the alph]-silylamine 20e is high; when n=1, proton transfer in the intermediate anion 64 and displacement of the phenyl group leads to the silaindane 66; when n=2, fragmentation of the intermediate anion 80, and capture

  苯基二甲基甲硅烷基锂以各种方式与N，N-二甲基酰胺反应，具体取决于化学计量，温度以及最巧妙地取决于酰胺的结构，结构中似乎很小的变化导致其性质的深刻变化。产品。当将等摩尔量的甲硅烷基锂试剂和N，N-二甲基酰胺6在-78℃下在THF中混合，并将混合物在-78℃下淬灭时，产物是相应的酰基硅烷。如果在淬灭之前将同一混合物加热至-20摄氏度，则该产品为顺式二烯胺11。二烯胺容易从顺式异构化为反式，易氧化为二烯二胺，更难水解为α-氨基酮13。如果使用两当量的甲硅烷基锂试剂，则产物为α-甲硅烷基胺20。烯二胺的形成机理似乎是通过四面体中间体17的布鲁克重排，随后是硅烷氧化物的损失，从而得到卡宾或卡宾类物质。“卡宾”与布鲁克重排亲核试剂结合，得到中间体28，该中间体失去另一个硅烷氧化物离子，得到烯二胺。相同的卡宾可被第二当量的甲硅烷基锂试剂攻击，得到α-甲硅烷基胺20。其他亲核试剂，如烷基锂，苯基锂和三丁
