  Total Synthesis of Novel 6-Substituted Lavendamycin Antitumor Agents

  摘要：

  Novel 6-substituted lavendamycins have been synthesized for the first time. The key step in these syntheses is a Pictet-Spengler condensation (Scheme 1). Efficient methods for the synthesis of each compound, including a novel reaction for the facile introduction of alkylamino groups at the C-6 position of the lavendamycin system, are discussed. Possible mechanisms for these reactions are also presented.

  lavendamycin analogues with various substituents were synthesized and evaluated as potential NAD(P)H:quinone oxidoreductase (NQO1)-directed antitumor agents. Pictet-Spengler condensation of quinoline- or quninoline-5,8-dione aldehydes with tryptamine or tryptophans yielded the lavendamycins. Metabolism studies with recombinant human NQO1 revealed that addition of NH2 and CH2OH groups at the quinolinedione-7-position

  合成了具有各种取代基的新型拉文霉素类似物，并将其评估为潜在的NAD（P）H：醌氧化还原酶（NQO1）定向的抗肿瘤药。喹啉或喹诺啉5,8-二酮醛与色胺或色氨酸的Pictet-Spengler缩合产生拉文霉素。重组人NQO1的代谢研究表明，在喹啉二酮7位和吲哚吡啶2'位添加NH2和CH2OH基团对底物特异性具有最大的积极影响。最好和最差的底物是37（2'-CH2OH-7-NH2衍生物）和31（2'-CONH2-7-NHCOC3H7-n衍生物），还原速率分别为263 +/- 30和0.1 +/- 0.1 micromol /最小/毫克NQO1。确定了拉文霉素对人结肠腺癌细胞的细胞毒性。与缺乏NQO1的BE-WT细胞相比，NQO1的最佳底物对富含NQO1的BE-NQ细胞的毒性也最强，选择性为37。分子对接支持了一种模型，其中最佳的底物能够与活性位点的关键残基进行有效的氢键相互作用，以及氢化物离子的接收。
