    摘要:
    先前已经研究了表皮生长因子受体(EGFR)信号传导途径在不同类型的恶性肿瘤进展中的重要作用,其中靶向EGFR的小分子的发展是设计抗肿瘤药物的众所周知的策略。在这里,我们报告设计和合成的两个系列的6-(2-取代的乙酰胺基)-4-苯胺基喹唑啉(6a-x和13a-d)作为EGFR抑制剂。在体外评估所有新合成的喹唑啉衍生物对MCF-7(乳腺癌)和HepG2(肝细胞癌)细胞系的抗增殖活性。特别是,化合物6n对MCF-7和HepG2细胞系具有明显的抑制活性(IC 50 分别与埃洛替尼(IC 50  = 20和25μM )相比分别为3和16μM )。在MCF-7细胞系中6n的蛋白质印迹显示6n对减少EGFR和ERK磷酸化水平的双重抑制活性。此外,ELISA分析证实了化合物6n的抗EGFR活性(IC 50  = 0.037μM)。最后,一项分子对接研究表明,在EGFR的ATP催化结合位点内可能存在6n的结

    A series of 4,6-substituted-(diaphenylamino)quinazolines as c-Src inhibitors have been prepared and their biological activity has also been evaluated. All the compounds displayed potential antiproliferation activities, with IC50 values ranging from 3.42 μM to 118.81 μM in five human tumor cell lines. Particularly, compound 15 exhibited higher cytotoxicity against the tested five tumor cell lines compared to the other small molecules. Generally, most of these compounds showed selectivity between the A549 cells and the other four cells, according to their corresponding IC50 values. The results obtained from the in vitro enzyme assay indicated compound 15 has remarkable inhibitory activity against c-Src kinase with an IC50 value of 27.3 nM, which is comparable to the control compounds. Furthermore, molecular docking and QSAR study by means of DS 3.5 (Discovery Studio 3.5, Accelrys, Co. Ltd) explored the binding modes and the structure and activity relationship (SAR) of these derivatives.

    According to the classical pharmacophore fusion strategy, a series of 6-arylureido-4-anilinoquinazoline derivatives (Compounds 7at) were designed, synthesized, and biologically evaluated by the standard CCK-8 method and enzyme inhibition assay. Among the title compounds, Compounds 7a, 7c, 7d, 7f, 7i, 7o, 7p, and 7q exhibited promising anti-proliferative bioactivities, especially Compound 7i, which had excellent antitumor activity against the A549, HT-29, and MCF-7 cell lines (IC50 = 2.25, 1.72, and 2.81 μM, respectively) compared with gefitinib, erlotinib, and sorafenib. In addition, the enzyme activity inhibition assay indicated that the synthesized compounds had sub-micromolar inhibitory levels (IC50, 11.66–867.1 nM), which was consistent with the results of the tumor cell line growth inhibition tests. By comparing the binding mechanisms of Compound 7i (17.32 nM), gefitinib (25.42 nM), and erlotinib (33.25 nM) to the EGFR, it was found that Compound 7i could extend into the effective region with a similar action conformation to that of gefitinib and interact with residues L85, D86, and R127, increasing the binding affinity of Compound 7i to the EGFR. Based on the molecular hybridization strategy, 14 compounds with EGFR inhibitory activity were designed and synthesized, and the action mechanism was explored through computational approaches, providing valuable clues for the research of antitumor agents based on EGFR inhibitors.

    根据经典药效团融合策略,设计、合成并通过标准CCK-8方法和酶抑制活性评估了一系列6-芳基脲基-4-苯胺基喹唑啉衍生物(化合物7at)。在这些化合物中,化合物7a7c7d7f7i7o7p7q展现出有希望的抗增殖生物活性,特别是化合物7i,对A549、HT-29和MCF-7细胞系表现出优秀的抗肿瘤活性(IC50分别为2.25、1.72和2.81 μM),与吉非替尼、厄洛替尼和索拉非尼相比。此外,酶活性抑制实验显示,合成的化合物具有亚微摩尔水平的抑制活性(IC50为11.66–867.1 nM),与肿瘤细胞系生长抑制实验结果一致。通过比较化合物7i(17.32 nM)、吉非替尼(25.42 nM)和厄洛替尼(33.25 nM)对EGFR的结合机制,发现化合物7i能够延伸到有效区域,与吉非替尼相似的作用构象相互作用于残基L85、D86和R127,增加化合物7i与EGFR的结合亲和力。基于分子杂交策略,设计并合成了14个具有EGFR抑制活性的化合物,并通过计算方法探索了作用机制,为基于EGFR抑制剂的抗肿瘤药物研究提供了宝贵线索。
