  Indolequinone Antitumor Agents:  Correlation between Quinone Structure, Rate of Metabolism by Recombinant Human NAD(P)H:Quinone Oxidoreductase, and in Vitro Cytotoxicity

  摘要：

  A series of indolequinones bearing various functional groups has been synthesized, and the effects of substituents on the metabolism of the quinones by recombinant human NAD(P)H: quinone oxidoreductase (NQO1) were studied. Thus 5-methoxyindolequinones were prepared by the Nenitzescu reaction, followed by functional group interconversions. The methoxy group was subsequently displaced by amine nucleophiles to give a series of amine-substituted quinones. Metabolism of the quinones by NQO1 revealed that, in general, compounds with electron-withdrawing groups at the indole 3-position were among the best substrates, whereas those with amine groups at the 5-position were poor substrates. Compounds with a leaving group at the 3-indolyl methyl position generally inactivated the enzyme. The toxicity toward non-small-cell lung cancer cells with either high NQO1 activity (H460) or no detectable activity (H596) was also studied in representative quinones. Compounds which were good substrates for NQO1 showed the highest selectivity between the two cell lines.

  1-methyl-1H-indole-3-carboxylates by cross-dehydrogenative coupling. However, the coupling reactions are a way to functionalize the α-carbon of iminiums from tertiary amines. The synthesis of 1-methyl-1H-indole-3-carboxylates from N,N-dimethylaniline with bromoacetates has not been reported. In the present work, we describe a novel route for synthesizing 1-methyl-1H-indole-3-carboxylates with N,N-dimethylaniline

  我们报告了一种通过交叉脱氢偶联合成 1-methyl-1 H -indole-3-carboxylates 的有效方法。然而，偶联反应是一种从叔胺中官能化亚胺的 α-碳的方法。从N , N-二甲基苯胺和溴乙酸盐合成 1-methyl- 1H- indole-3-carboxylates的报道尚未见报道。在目前的工作中，我们描述了一种合成 1-methyl-1 H -indole-3-carboxylates with N , N的新路线-二甲基苯胺和范围广泛的溴乙酸苯酯衍生物。程序简单、产率高至极佳 (69–90%) 等特点使该方法成为在叔丁基存在下使用 Cu(OAc) 2 ·H 2 O作为催化剂制备吲哚衍生物的高效程序氢过氧化物。

• C–H Activation-Based Traceless Synthesis via Electrophilic Removal of a Directing Group. Rhodium(III)-Catalyzed Entry into Indoles from <i>N</i>-Nitroso and α-Diazo-β-keto Compounds

  A distinct C–H activation-based traceless synthetic protocol via electrophilic removal of a directing group is reported, complementing the currently exclusively used nucleophilic strategy. Rh(III)-catalyzed, N-nitroso-directed C–H activation allows the development of a traceless, atom- and step-economic, cascade approach for the synthesis of indole skeletons, starting from readily available N-nitroso
