All of the title compounds were confirmed by ₁H NMR, ₁₃C NMR and HRMS. The anti-tumor activity of the title compounds against HCT116, MD-MBA-231, C6, A549 and MCF-7 cancer cell lines were tested by MTT assay. The results showed that all compounds had good anti-tumor activity, especially compounds 5a, 5b, 5c, 5e, 5i, 5p and 5r, showed 20 to 100 folds activity enhancement than the positive control 5-fluorouracil. 5b was the most potential one among them, whose IC₅₀ of HCT116, MD-MBA-231, C6, A549 and MCF-7 were 3.26, 3.06, 0.63, 0.68 and 2.32 μmol/L. These findings suggested that these derivatives have a significant inhibitory effect on tumor cells proliferation, which laid the foundation to design and synthesize new 5H-pyrimido[5,4-b]indol-2-amine based derivatives as anti-tumor compounds, providing advices to the pharmaceutical researchers. 查看全文查看/发表评论下载PDF阅读器 相关附件：版权转让声明书 -->
