  Synthesis, topoisomerase I and II inhibitory activity, cytotoxicity, and structure–activity relationship study of hydroxylated 2,4-diphenyl-6-aryl pyridines

  摘要：

  A new series of 2,4-diphenyl-6-aryl pyridines containing hydroxyl group(s) at the ortho, meta, or para position of the phenyl ring were synthesized, and evaluated for topoisomerase I and II inhibitory activity and cytotoxicity against several human cancer cell lines for the development of novel anticancer agents. Structure-activity relationship study revealed that the substitution of hydroxyl group( s) increased topoisomerase I and II inhibitory activity in the order of meta > para > ortho position. Substitution of hydroxyl group on the para position showed better cytotoxicity. (c) 2010 Elsevier Ltd. All rights reserved.

  domino method has been established for modular synthesis of a diverse range of medicinally promising hydroxyarylated unsymmetrical pyridines in good to high chemical yields with an excellent regioselectivity. This domino process involves a range of N-sulfonyl ketimines as C,N-binucleophiles, enolizable ketones, and aromatic/heteroaromatic aldehydes using ammonium acetate as an ideal promoter under neat

  已经建立了一种新的无金属，无氧化剂和无溶剂的环保多米诺骨牌方法，用于以良好的化学收率和良好的区域选择性，以模块化方式合成多种医学前景看好的羟基芳基化不对称吡啶。该多米诺过程涉及一系列N-磺酰基酮亚胺，如C，N-双亲核试剂，可烯化的酮和芳香族/杂芳香族醛，使用乙酸铵作为理想的促进剂，在纯净条件下产生两个新的CC键和一个CN键。值得注意的是，中性反应条件温和到足以耐受一定范围的功能并覆盖各种底物，因此为接触包括碳-和杂环稠合吡啶的三和四取代吡啶提供了强大的途径。有趣的是，实用，可扩展，
