  摘要：

  High-throughput screening has identified a novel class of inhibitors of the checkpoint kinase Wee1, which have potential for use in cancer chemotherapy. These inhibitors are based on a 4-phenylpyrrolo[3,4-c]carbazole- 1,3(2H,6H)-dione template and have been shown by X-ray crystallography to bind at the ATP site of the enzyme. An extensive study of the effects of substitution around this template has been carried out, which has identified substituents which lead to improvements in potency and selectivity for Wee1. While retention of the maleimide ring and pendant 4-phenyl group is necessary for potency, replacement of the carbazole nitrogen by oxygen is well tolerated and results in improved Wee1 selectivity against the related checkpoint kinase Chk1. Wee1 potency and selectivity are also enhanced by the incorporation of lipophilic functionality at the 2'-position of the 4-phenyl ring, and Wee1 selectivity against Chk1 is favored by C3-C5 alkyl substitution of the carbazole nitrogen. These studies provide a basis for the design of active analogues of the pyrrolocarbazole lead with improved physical properties.

  摘要：

  在钯催化剂的作用下，2,6-二溴-4-(3′,5′-二叔丁基-4′-乙酰氧基苯基)苯乙烯在一锅反应中聚合，随后水解和氧化得到超支化的聚[(4-(3′、5′-二叔丁基-4′-基氧基苯基）-1,2,(6)-亚苯基乙烯）]，它在三个方向上同时满足交替但非 Kekulé 型的π-共轭和悬垂苯氧基未配对电子的铁磁连接。原子力显微镜图像、异常低的溶液粘度和苯酚基团的低化学反应活性表明，这种聚合物具有高度支化的球状结构。尽管支化极为密集，但聚合物骨架中的π-共轭结构仍得以保持，这一点已在光电子学和 EPR 光谱中得到证实。即使每个单体单元的自旋浓度仅为 0.4，苯氧基聚合物的平均 S 值也达到了 3。
