  通过选择性 O-烷基化实用高效合成吉非替尼：一个新的瞬时保护基概念

  摘要：

  摘要描述了一个实用的过程，包括一个简单的四步程序，用于制备吉非替尼 (1)，一种靶向表皮生长因子受体的酪氨酸激酶抑制剂。实现了对先前报道的常规合成程序的显着改进。我们找到了有效的偶联条件，以最大限度地减少不可避免的 N-烷基化副产物 N-(3-chloro-4-fluorophenyl)-7-methoxy-6-(3-morpholinopropoxy)-N-(3-morpholinopropyl)-使用瞬态三甲基甲硅烷基保护基团的喹唑啉-4-胺 (3)。我们使用一种不需要任何反应步骤后处理的路线，以多克规模从市售的起始材料中以 81.1% 的总产率合成了吉非替尼。图形概要

  A novel series of 4-anilinoquinazoline analogues, DW (1–10), were evaluated for anticancer efficacy in human breast cancer (BT-20) and human colorectal cancer (CRC) cell lines (HCT116, HT29, and SW620). The compound, DW-8, had the highest anticancer efficacy and selectivity in the colorectal cancer cell lines, HCT116, HT29, and SW620, with IC50 values of 8.50 ± 2.53 µM, 5.80 ± 0.92 µM, and 6.15 ± 0.37 µM, respectively, compared to the non-cancerous colon cell line, CRL1459, with an IC50 of 14.05 ± 0.37 µM. The selectivity index of DW-8 was >2-fold in colon cancer cells incubated with vehicle. We further determined the mechanisms of cell death induced by DW-8 in SW620 CRC cancer cells. DW-8 (10 and 30 µM) induced apoptosis by (1) producing cell cycle arrest at the G2 phase; (2) activating the intrinsic apoptotic pathway, as indicated by the activation of caspase-9 and the executioner caspases-3 and 7; (3) nuclear fragmentation and (4) increasing the levels of reactive oxygen species (ROS). Overall, our results suggest that DW-8 may represent a suitable lead for developing novel compounds to treat CRC.

  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.
