  Discovery of quinone-directed antitumor agents selectively bioactivated by NQO1 over CPR with improved safety profile

  摘要：

  In this work, we mainly focused on discovering compounds with good selectivity for NQO1 over CPR. The NQO1-mediated two-electron reduction of compounds would kill cancer cells selectively, while CPR-mediated one-electron reduction would induce potential hepatotoxicity. Several novel quinone-directed antitumor agents were discovered as specific NQO1 substrates through structure-activity relationship studies. Among them, compound 3,7,8-trimethylnaphtho[1,2-b] furan-4,5-dione (12b) emerged as the most specific substrate of the two-electron oxidoreductase NQO1 and could hardly be reduced by CPR. It afforded the highest selectivity between NQO1/CPR (selectivity ratio = 6.37), much higher than the control beta-lapachone (selectivity ratio = 1.36), indicated 12b may possess superior safety profile. The electrochemical studies provided a reasonable explanation to the good selectivity toward NQO1. Molecular docking studies supported that 12b was capable of forming additional C-H... pi interactions with Trp105 and Phe178 residues compared to the control beta-lap. In addition, compound 12b was shown to kill cancer cells efficiently both in vitro and in vivo model. This work gave us a promising and novel scaffold for further investigation.

  A straightforward method for synthesizing ortho-naphthoquinones was identified using an easily available cobalt-Schiff base complex. Efficient oxidation of phenols to ortho-naphthoquinones was useful in obtaining compounds with potent biological activity for the treatment of acute myeloid leukemia (AML). Among these compounds, the compound 4h effectively inhibited the proliferation of different AML

  使用容易获得的钴-席夫碱钴配合物鉴定了一种简单的合成邻萘醌的方法。将苯酚有效氧化为邻萘醌可用于获得具有有效生物学活性的化合物，用于治疗急性髓细胞性白血病（AML）。在这些化合物中，化合物4h在体外有效抑制了不同AML细胞系的增殖。进一步的体内抗肿瘤研究表明，在MV4-11异种移植模型中，以40 mg / kg / d服用4h导致肿瘤消退，导致肿瘤消退，而无明显毒性。发现钴-席夫碱配合物是苯酚向邻醌转化的有效催化剂，化合物4h代表了一种潜在支架，可优化AML治疗药物的生产。
