  Antiproliferative Efficacy of N-(3-chloro-4-fluorophenyl)-6,7-dimethoxyquinazolin-4-amine, DW-8, in Colon Cancer Cells Is Mediated by Intrinsic Apoptosis

  摘要：

  一系列新型的4-苯胺基喹唑啉类似物DW（1-10）在人类乳腺癌（BT-20）和人类结肠癌（CRC）细胞系（HCT116、HT29和SW620）中进行了抗癌功效评估。化合物DW-8在结肠癌细胞系HCT116、HT29和SW620中表现出最高的抗癌功效和选择性，其IC50值分别为8.50±2.53 µM、5.80±0.92 µM和6.15±0.37 µM，而非癌性结肠细胞系CRL1459的IC50为14.05±0.37 µM。DW-8在与载体培养的结肠癌细胞中的选择性指数大于2倍。我们进一步确定了DW-8在SW620结肠癌细胞中诱导细胞死亡的机制。DW-8（10和30 µM）通过（1）在G2期引起细胞周期停滞；（2）激活内源性凋亡途径，表现为caspase-9和执行者caspase-3和7的激活；（3）核碎裂和（4）增加活性氧化物种（ROS）水平来诱导凋亡。总的来说，我们的结果表明DW-8可能是开发治疗CRC的新型化合物的合适先导。

  A series of novel 4-anilinoquinazoline derivatives (3a-3j) has been synthesized and evaluated as potential inhibitors for protein kinases implicated in Alzheimer's disease. Among all the synthesized compounds, compound 3e (N-(3,4-dimethoxyphenyl)-6,7-dimethoxyquinazolin-4-amine) exhibited the most potent inhibitory activity against CLK1 and GSK-3 alpha/beta kinase with IC50 values of 1.5 mu M and 3 mu M, respectively. Docking studies were performed to elucidate the binding mode of the compounds to the active site of CLK1 and GSK-3 beta. The results of our study suggest that compound 3e may serve as a valuable template for the design and development of dual inhibitors of CLK1 and GSK-3 alpha/beta enzymes with potential therapeutic application in Alzheimer's disease.

  Three series of 6,7-dimethoxyquinazoline derivatives substituted in the 4-position by aniline, N-methylaniline and aryloxy entities, targeting EGFR and VEGFR-2 tyrosine kinases, were designed and synthesized. Pharmacological activities of these compounds have been evaluated for their enzymatic inhibition of VEGFR-2 and EGFR and for their antiproliferative activities on various cancer cell lines. We have studied the impact of the variation in the 4-position substitution of the quinazoline core. Substitution by aryloxy groups led to new compounds which are selective inhibitors of VEGFR-2 enzyme with IC50 values in the nanomolar range in vitro. (C) 2011 Elsevier Ltd. All rights reserved.
