  Indenoindolone derivatives as topoisomerase II–inhibiting anticancer agents

  摘要：

  Based on known heterocyclic topoisomerase II inhibitors and anticancer agents, various indenoindolone derivatives were predicted as potential topoisomerase II-inhibiting anticancer agents. They are hydrazones, (thio)semicarbazones, and oximes of indenoindolones, and indenoindolols. These derivatives with suitable substitutions exhibited potent specific inhibition of human DNA TopoII alpha, while not showing inhibition of topoisomerase I and DNA intercalation, despite the fact that parent indenoindolones are known poor/moderate inhibitors of topoisomerase II. The potent topoisomerase II inhibitor indenoindolone derivatives exhibited good anticancer activities compared to etoposide and 5-fluorouracil, and relatively low toxicity to normal cells. These derivatizations of indenoindolones were found to result in enhancement of anticancer activities. (C) 2012 Elsevier Ltd. All rights reserved.

  Intramolecular oxidative coupling of 3-indolylarylketones with Pd(II)-catalysis under air: convenient access to indenoindolones

  摘要：

  A Pd-catalyzed method has been developed for the intramolecular oxidative coupling of 3-indolylarylketones under open air as terminal oxidant toward the synthesis of indeno[1,2-b]indol-10(5H)-ones. This reaction represents an intramolecular coupling with dual activation of C-H bonds for electron-deficient arenes, while such reactions are common for electron-rich arenes. Pd(II)-catalysis with pivalic acid as co-catalyst has been found to be crucial. The reaction undergoes without indole N-H-protection. (C) 2012 Elsevier Ltd. All rights reserved.
