Structure-based design, synthesis and evaluation of novel anthra[1,2-d]imidazole-6,11-dione derivatives as telomerase inhibitors and potential for cancer polypharmacology
A series of anthra[1,2-d]imidazole-6,11-dione derivatives were synthesized and evaluated for telomerase inhibition, hTERT expression and suppression of cancer cell growth in vitro. All of the compounds tested, except for compounds 4, 7, 16, 24, 27 and 28 were selected by the NCI screening system. Among them, compounds 16, 39, and 40 repressed hTERT expression without greatly affecting cell growth,
合成了一系列蒽[1,2 - d ]咪唑-6,11-二酮衍生物,并对其体外端粒酶抑制,hTERT表达和癌细胞生长抑制进行了评估。所有化合物进行测试,除了化合物4,7,16,24,27和28由NCI筛选系统筛选。其中,化合物16,39,和40压抑端粒酶表达而不大大影响细胞生长,提示为朝向选择性的hTERT表达。综上所述,我们的发现表明,细胞毒性和端粒酶抑制作用的分析可能为进一步开发潜在的端粒酶和多药理靶向策略提供信息。

We recently reported the use of PSCl3 for the thiophosphorylation of alkylamines where the resulting N-thiophosphoramidate ions could be readily S-alkylated (Chem. Commun., 2011, 47, 6156–6158.). Herein we report the development of this methodology using amino acid, amino sugar, aminonucleoside and aniline substrates. The hydrolysis properties of N-thiophosphoramidate ions and their reactivities towards alkylating agents are also explored. In addition, we demonstrate the application of our approach to the preparation of a small library of compounds, including quinoline-based N,S-dialkylthiophosphoramidates which were tested for antileishmanial activity.
