  New quinoxaline 1,4-di-N-oxides. Part 1: Hypoxia-selective cytotoxins and anticancer agents derived from quinoxaline 1,4-di-N-oxides

  摘要：

  Hypoxic cells which are common feature of solid tumors are resistant to both anticancer drugs and radiation therapy. Thus, the identification of drugs with the selective toxicity toward hypoxic cells is an important target in anticancer chemotherapy. Tirapazamine has been shown to be an efficient and selective cytotoxin after bioreductive activation in hypoxic cells which is thought to be due to the presence of the 1,4-di-N-oxide. A new series of quinoxaline 1,4-di-N-oxides and fused quinoxaline di-N-oxides were synthesized and evaluated for hypoxic-cytotoxic activity on EAC cell line. Compound 10a was the most potent cytotoxin IC50 0.9 mu g/mL, potency 75 mu g/mL, and was approximately 15 times more selective cytotoxin (HCR > 111) than 3-aminoquinoxaline-2-carbonitrile which has been used as a standard (HCR > 7.5). Compounds 4 and 3a,b were more selective than the standard. In addition, antitumor activity against Hepg2 (liver) and U251 (brain) human cell lines was evaluated, compounds 9c and 8a were the most active against Hepg2 with IC50 values 1.9 and 2.9 mu g/mL, respectively, however, all the tested compounds were nontoxic against U251 cell line.

  Integrated computational approaches for Mycobacterium tuberculosis (Mtb) are useful to identify new molecules that could lead to future tuberculosis (TB) drugs. Our approach uses information derived from the TBCyc pathway and genome database, the Collaborative Drug Discovery TB database combined with 3D pharmacophores and dual event Bayesian models of whole-cell activity and lack of cytotoxicity. We

  结核分枝杆菌（Mtb）的集成计算方法可用于识别可能导致未来结核病（TB）药物的新分子。我们的方法使用的信息来自TBCyc途径和基因组数据库，协作药物发现TB数据库，3D药效团以及全细胞活性和缺乏细胞毒性的双事件贝叶斯模型。我们已经对可能充当TB代谢组中底物和代谢物模拟物的大量分子进行了优先排序。我们使用基于Mtb的底物和代谢物的66个药效团，通过计算搜索了200,000多种商业分子，并进一步用贝叶斯模型进行了过滤。我们最终在体外测试了110种化合物，得到了两种目标化合物，BAS 04912643和BAS 00623753（MIC分别为2.5和5μg/ mL）。这些分子被用作领先优势优化的起点。最有前途的一类被证明是喹喔啉二-N-氧化物，其通过转录谱分析来诱导与已知质子体最相似的mRNA水平扰动而得到证明。其中之一，SRI58在Vero细胞中的MIC = 1.25μg/ mL（相对于Mtb）和CC50，>

  A series of 2-acetyl and 2-benzoyl-6(7)-substituted quinoxaline 1,4-di-N-oxide derivatives were synthesized and evaluated for in vitro antituberculosis activity. The results show that 2-acetyl-3-methylquinoxaline 1,4-di-N-oxide derivatives with chlorine, methyl or methoxy group in position 7 of the benzene moiety (compounds 2, 4 and 6, respectively) and unsubstituted (3) have good antitubercular activity, exhibiting EC90/MIC values between 0.80 and 4.29. In conclusion, the potency, selectivity and low cytotoxicity of these compounds make them valid leads for synthesizing new compounds that possess better activity.
