A series of 1,4-phenylene-bis-chalcones 3a-3h were synthesized by the reaction of terephthalaldehyde with substituted arylketones in this study. The novel 1,4-phenylene-bis-pyrimidine-2-amine derivatives 5a-5h were obtained by the addition of guanidine hydrochloride to 1,4-phenylene-bis-chalcone 3a-3h in ethanolic KOH under reflux conditions. The structure of the compounds was explained by means of IR, $^1}$H NMR, $^13}$C NMR, and elemental analyses. The anticancer activities of 3a-3h and 5a-5h were investigated against rat brain tumor cells and human uterus carcinoma in vitro$.$ Activity tests were performed as dose-dependent assays at eight concentrations. The positive control was 5-fluorouracil (5-FU). Compounds 3c and 3d were examined and they showed high activities as compared to 5-FU against C6 (rat brain tumor) and HeLa (human uterus carcinoma) cells. The anticancer activity of 5h was better than that of 5-FU at high concentrations cell-selectively against C6 cells.
在本研究中,通过邻苯二甲醛与取代芳基酮的反应合成了系列1,4-亚苯基双查尔酮3a-3h。在回流条件下,将盐酸胍加入到1,4-亚苯基双查尔酮3a-3h中,在乙醇钾溶液中得到了新型1,4-亚苯基双嘧啶-2-胺衍生物5a-5h。通过红外光谱、核磁共振(1H NMR和13C NMR)及元素分析解释了化合物的结构。对3a-3h和5a-5h的抗癌活性进行了研究,针对大鼠脑肿瘤细胞和人子宫颈癌在体外进行了活性测试,活性测试以剂量依赖性方式在八种浓度下进行。阳性对照为5-氟尿嘧啶(5-FU)。经过检测,化合物3c和3d显示出相较于5-FU对C6(大鼠脑肿瘤)和HeLa(人子宫颈癌)细胞的高活性。在高浓度下,5h对C6细胞的选择性抗癌活性优于5-FU。
