Twenty two new 5-fluorouracil (5-FU) derivatives, 2-butoxy-4-substituted 5-fluoropyrimidines, were synthesized and characterized by IR, 1 H NMR, MS, HRMS. All compounds were preliminarily evaluated by MTT assay on human liver BEL-7402 cancer cell line in vitro. Ten compounds were selected to test their cytotoxic activity against A549, HL-60 and MCF-7 cancer cell lines in vitro. These compounds were
合成了 22 种新的 5-氟尿嘧啶 (5-FU) 衍生物,即 2-丁氧基-4-取代的 5-氟嘧啶,并通过 IR、1 H NMR、MS、HRMS 对其进行了表征。所有化合物均通过MTT法在体外对人肝BEL-7402癌细胞系进行初步评价。选择了十种化合物以在体外测试它们对 A549、HL-60 和 MCF-7 癌细胞系的细胞毒活性。这些化合物比其他细胞系对BEL-7402更敏感,特别是化合物6b、6d-f、6p、6s-u的细胞毒活性在亚微摩尔级。2-butoxy-4-chloro-5fluoropyrimidine (5) 显示对 A549、HL-60 和 MCF-7 的最高细胞毒性效力,IC50 值分别为 0.10、1.66 和 0.59 µM。化合物 6d 和 6e 对 MCF-7 有效,IC50 为 9.73 µM 和 HL-60,IC50 分别为 8.83 µM。
