  Azaindenoisoquinolines as Topoisomerase I Inhibitors and Potential Anticancer Agents: A Systematic Study of Structure–Activity Relationships

  摘要：

  A comprehensive study of a series of azaindenoisoquinoline topoisomerase I (Top 1) inhibitors is reported. The synthetic pathways have been developed to prepare 7-, 8-, 9-, and 10-azaindenoisoquinolines. The present study shows that 7-azaindenoisoquinolines possess the greatest Top1 inhibitory activity and cytotoxicity. Additionally, the introduction of a methoxy group into the D-ring of 7-azaindenoisoquinolines improved their biological activities, leading to new lead molecules for further development. A series of QM calculations were performed on the model "sandwich" complexes of azaindenoisoquinolines with flanking DNA base pairs from the Drug-Top1-DNA ternary complex. The results of these calculations demonstrate how changes in two forces contributing to the pi-pi stacking (dispersion and charge-transfer interactions) affect the binding of the drug to the Top1-DNA cleavage complex and thus modulate the drug's Top1 inhibitory activity.

  The development of catalysts based on earth abundant metals in place of noble metals is becoming a central topic of catalysis. We herein report a cobalt/tetraphosphine complex catalyzed homogeneous hydrogenation of polar unsaturated compounds using an air- and moisture-stable and scalable precatalyst. By activation with potassium hydroxide, this cobalt system shows both high efficiency (up to 24000

  基于地球上丰富的金属代替贵金属的催化剂的开发正在成为催化的中心话题。我们在此报告了一种钴/四膦配合物催化的极性不饱和化合物的均相氢化反应，该反应使用空气和水分稳定且可缩放的预催化剂。通过用氢氧化钾活化，该钴系统显示出高效率（高达 24000 TON 和 12000 h-1 TOF）和对各种醛、酮、亚胺甚至 N-杂芳烃的优异化学选择性。1,2-还原优于 1,4-还原使该方法成为制备烯丙醇和胺的有效方法。同时，具有挑战性的 N-杂芳烃的有效氢化也具有优异的官能团耐受性。机理研究和控制实验表明 CoIH 复合物在催化循环中起到强氢化物供体的作用。对催化循环中的每个钴中间体进行了表征，并提出了一种合理的外球机制。值得注意的是，外部无机碱在该反应中起着多种作用，并且几乎在催化循环的每一步都起作用。
