synthesized from the corresponding 4-(iodoanilino)quinazolines or 4-(iodophenoxy)quinazolines with N,N-dicyclohexylprop-2-ynylamine by the Sonogashira coupling followed by palladium-catalyzed hydride-transfer reaction. Cell growth inhibition of 13a–h toward A431, Kato III, SKBR3, and HepG2 was examined. Among the compounds synthesized, 13a showed a similar cell growth inhibition to Tarceva. Moreover, 13d
Allenic quinazolines 13a – h被设计为Tarceva的模拟物,Tarceva是一种表皮生长因子受体(EGFR)酪氨酸激酶抑制剂,由相应的4-(碘代苯胺基)喹唑啉或4-(碘代苯氧基)喹唑啉与N,N-二环己基丙醇合成通过Sonogashira偶联生成-2-乙胺,然后进行钯催化的氢化物转移反应。检查了13a – h对A431,Kato III,SKBR3和HepG2的细胞生长抑制作用。在合成的化合物中,13a显示出与特罗凯相似的细胞生长抑制作用。而且13d和13h 尽管在100μM的化合物浓度下未观察到对其他三个细胞系的显着抑制作用,但对Kato III细胞具有特定的生长抑制作用(分别为IC 50 = 12和4.7μM)。
