In order to find efficient new antitumor drugs, a series of novel trifluoromethyl-substituted pyrimidine derivatives were designed and synthesized, and the bioactivity against four human tumor cells (PC-3, MGC-803, MCF-7 and H1975) was evaluated by MTT assay. Compound 17v displayed potent anti-proliferative activity on H1975 (IC₅₀ = 2.27 μΜ), which was better than the positive control 5-FU (IC₅₀ = 9.37 μΜ). Further biological evaluation studies showed that compound 17v induced apoptosis of H1975 cells and arrested the cell cycle at G2/M phase. Furthermore, compound 17v induced H1975 cells apoptosis through increasing the expression of pro-apoptotic proteins Bax and p53 and down-regulating the anti-apoptotic protein Bcl-2. In addition, compound 17v was able to be tightly embedded in the active pocket of EGFR. In summary, these results demonstrated that compound 17v has a potential as a lead compound for further investigation.

为了寻找高效的抗肿瘤新药，设计合成了一系列新型三氟甲基取代的嘧啶衍生物，并通过MTT评估了对四种人类肿瘤细胞（PC-3、MGC-803、MCF-7和H1975）的生物活性。化验。化合物17v对H1975显示出有效的抗增殖活性（IC ₅₀  = 2.27 μM），优于阳性对照5-FU（IC ₅₀  = 9.37 μM）。进一步的生物学评价研究表明，化合物17v 可诱导H1975细胞凋亡，并将细胞周期阻滞在 G2/M 期。此外，化合物17v通过增加促凋亡蛋白 Bax 和 p53 的表达并下调抗凋亡蛋白 Bcl-2 诱导 H1975 细胞凋亡。此外，化合物17v能够紧密嵌入 EGFR 的活性口袋中。总之，这些结果表明化合物17v具有作为进一步研究的先导化合物的潜力。
