The pyrrolo[2,1-f][1,2,4]triazine nucleus was identified as a novel kinase inhibitor template which effectively mimics the well-known quinazoline kinase inhibitor scaffold. Attachment of a 4-((3-chloro-4-fluorophenyl)amino) substituent to the template provided potent biochemical inhibitors of the tyrosine kinase activity of EGFR, as well as inhibition of cellular proliferation of the human colon tumor
吡咯并[2,1-f] [1,2,4]三嗪核被确定为新型激酶抑制剂模板,可有效模拟众所周知的喹唑啉激酶抑制剂支架。4-((3-氯-4-氟苯基)氨基)取代基与模板的连接为EGFR的酪氨酸激酶活性提供了有效的生化抑制剂,并抑制了人结肠肿瘤细胞系DiFi的细胞增殖。4-((3-羟基-4-甲基苯基)氨基)取代基的附着提供了有效的VEGFR-2抑制剂,该抑制剂也显示出对人脐静脉内皮细胞VEGF依赖性增殖的影响。通过在5或6位而不是7位取代来维持生物活性,这表明前一个位置是引入可调节物理化学性质的侧链的有前途的位点。
