摘要/Abstract

为了寻找高效的新型抗肿瘤药物，设计并合成了一系列新型含三氟甲基的2，4-取代嘧啶衍生物，并对目标化合物在EC-109（人食管癌细胞），MGC-803（人胃癌细胞），PC-3（人前列腺癌细胞）和HepG-2（人肝癌细胞）进行抗肿瘤活性评价，结果显示部分化合物对PC-3表现出中度至强效的抗肿瘤活性.其中，2-（（（4-（（1-甲基-1H-四唑-5-基）硫基）-6-（三氟甲基）嘧啶-2-基）硫基）甲基）苯并[d]噻唑（13w）对PC-3具有较强的抗肿瘤活性，IC₅₀为1.76 μmol·L^-1，抗肿瘤活性明显优于阳性对照药5-氟尿嘧啶.

In order to find more effective antitumor drugs, a series of novel 2,4-substituted pyrimidine derivatives containing trifluoromethyl were designed, synthesized, and evaluated for antitumor activity aganist EC-109 (human esophageal cancer cell), MGC-803 (human gastric cancer cell), PC-3 (human prostate cancer cell) and HepG-2 (human liver cancer cell). The results showed that some compounds displayed moderate to potent antitumor activity against PC-3. Among them, 2-(((4-((1-methyl-1H-tetrazol-5-yl)thio)-6-(trifluoromethyl)pyrimidin-2-yl)thio)methyl)benzo[d]thiazole (13w) possesses strong antitu-mor activity against PC-3 with IC₅₀ value of 1.76 μmol·L^-1, and the antitumor activity is significantly better than the positive control drug of 5-fluorouracil.
Key words: trifluoromethyl, 2,4-substituted pyrimidine derivatives, antitumor activity
