    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。

    HDAC6的异常生物学功能与多种肿瘤的发生、发展密切相关,使得HDAC6逐渐成为癌症治疗的有希望的治疗靶点,并激励着研究人员探索和开发选择性HDAC抑制剂。本研究基于HDAC抑制剂的经典药效团模型,通过修饰Cap组设计合成了20个化合物,并通过抗增殖和酶抑制实验评估了目标化合物的生物学活性。标题化合物对选定的肿瘤细胞系表现出不同程度的抑制活性,尤其是化合物9m、9q和12c,在酶水平上进一步评估。酶抑制试验表明化合物12c具有广谱酶抑制活性,化合物9m和9q更倾向于抑制HDAC6,在代表性亚型中表现出一定的选择性抑制活性。此外,通过计算方法进一步探索了化合物9q和12c在HDAC1和6中的结合模式,以阐明选择性抑制活性的分子机制,为发现新型HDAC6抑制剂提供有价值的提示。
  • Design, synthesis and antitumor evaluation of phenyl N-mustard-quinazoline conjugates

    日期:2011.3
    A series of N-mustard-quinazoline conjugates was synthesized and subjected to antitumor studies. The N-mustard pharmacophore was attached at the C-6 of the 4-anilinoquinazolines via a urea linker. To study the structure-activity relationships of these conjugates, various substituents were introduced to the C-4 anilino moiety. The preliminary antitumor studies revealed that these agents exhibited significant antitumor activity in inhibiting various human tumor cell growths in vitro. Compounds 21b, 21g, and 21h were selected for further antitumor activity evaluation against human breast carcinoma MX-1 and prostate PC-3 xenograft in animal model. These agents showed 54-75% tumor suppression with low toxicity (5-7% body-weight changes). We also demonstrate that the newly synthesized compounds are able to induce DNA cross-linking through alkaline agarose gel shift assay and inhibited cell cycle arrest at G2/M phase.
