Synthesis and antitumor activity of C-3 thiazolo [3, 2-b][1, 2, 4]triazole-substituted pefloxacin derivatives

  • 摘要: 为寻找抗肿瘤氟喹诺酮类化合物的新方法,用稠杂环核作为培氟沙星( 1 )C-3羧基的生物电子等排体,设计合成了12个新的噻唑并[3,2-b][1,2,4]三唑类目标化合物( 6a ~ 6l ),其结构经元素分析和光谱数据确证。选择SMMC-7721、L1210和HL60 3种肿瘤细胞株进行体外抗增殖活性实验,结果表明目标化合物的抗肿瘤活性高于先导化合物 1 和相应的开环中间体硫醚酮( 5a ~ 5l ),其中苯环上有羟基或氟原子取代的目标化合物对SMMC-7721肿瘤细胞显示出较强的活性。基于此,噻唑并均三唑稠杂环可作为氟喹诺酮C-3羧基的等排体用于抗肿瘤氟喹诺酮类化合物的设计。
    Abstract: To search for fluoroquinolones(FQs)with antitumor activity, the C-3 carboxylic acid group of pefloxacin( 1 )was replaced by fused heterocyclic core, and twelve novel thiazolo[3, 2-b][1, 2, 4]triazole heterocycles( 6a - 6l )were designed and synthesized. The structures of target compounds were characterized by elemental analysis and spectral data. The results of the in vitro antiproliferative effect on SMMC-7721, L1210 and HL60 cell lines showed that the title compounds exhibited more significant antitumor activity than both of the pefloxacin and the corresponding opening-ring intermediates( 5a - 5l ). Among them, the target compounds which possess a benzene ring bearing a hydroxyl group( 6e )or a fluorine atom( 6j )exhibited more potent antiproliferative effect on SMMC-7721 cells than other compounds. Therefore, the antitumor fluoroquinolones can be designed by replacing the C-3 carboxylic acid group of fluoroquinolones with the thiazolo [3, 2-b][1, 2, 4] triazole moiety.
