  一种适宜于工业化生产制备吉非替尼的方法

  摘要：

  本发明公开了一种适宜于工业化生产制备吉非替尼的方法，以6,7‑二甲氧基‑3H‑喹唑啉‑4‑酮为原料，经过氯代，胺化，脱甲基，与N‑(3‑氯丙基)吗啉反应，共4步得到吉非替尼，以解决现有合成路线复杂漫长，总收率低，大量使用环境不友好试剂，工艺无法放大等问题。利用吡啶盐酸盐/DMSO高选择性脱去6‑位甲基，高收率得到关键中间体N‑(3‑氯‑4‑氟苯基)‑6‑羟基‑7‑甲氧基喹唑啉‑4‑胺，实现了该中间体的便捷合成。此合成方法原料便宜易得，路线短，可快速获得吉非替尼及6‑位不同基团修饰的衍生物。此制备方法解决了规模化生产原料药吉非替尼一大瓶颈问题。

  Novel Dual Use of Formamide-POCl₃ Mixture for the Efficient, One-Pot Synthesis of Condensed 2H-Pyrimidin-4-amine Libraries Under Microwave Irradiation

  摘要：

  The novel dual use of formamide-POCl3 mixture for the incorporation of a C-N fragment to form the pyrimidine nucleus and its subsequent chlorination in an efficient, one-pot synthesis of potentially bioactive condensed 2H-pyrimidin-4-amine libraries under microwave irradiation (MWI) is reported. The one-pot microwave-assisted synthetic protocol is high-yielding, ecofriendly, rapid, and novel as well as eliminates intermittent work-ups. The protocol can be adapted for the library synthesis of series of a condensed pyrimidines.

  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。
