2-butyl-4-chloro-1-3-[4-(3-iodophenyl amino)-7-methoxyquinazolin-6-yloxy]propyl}-1H-imidazole-5-carboxaldehyde (33) were found to be more potent against A431 cell line (IC50 3.5 and 3 μM) and their activities are comparable to gefitinib. Insilico docking experiments with human EGFR Tyrosine kinase domain (PDB id-2gs2) indicated that 33 docks at the same position as that of gefitinib involving Val702,
设计了一系列6,7-二烷氧基-4-苯胺基喹唑啉,通过在喹唑啉的6-位取代不同的杂环和在4-位取代多种苯胺来合成。通过使用非过度表达的肿瘤细胞作为阴性对照(乳腺癌细胞系MCF-7),筛选了这些新型喹唑啉化合物对过表达表皮生长因子受体的皮肤表皮样癌细胞系(A431)的细胞毒性作用。2-丁基-4-氯-1- 3- [7-甲氧基-4-(3-(三氟甲基)苯基氨基)喹唑啉-6-酰氧基]-丙基} -1 H-咪唑-5-甲醛(30)和2-丁基-4-氯-1- 3- [4-(3-碘苯基氨基)-7-甲氧基喹唑啉-6-酰氧基]丙基} -1 H-咪唑-5-甲醛(33)被发现对A431细胞系(IC 50 3.5和3μM)更有效,其活性与吉非替尼相当。使用人EGFR酪氨酸激酶结构域(PDB id-2gs2)进行的计算机对接实验表明,与吉非替尼的33个对接在同一位置,涉及Val702,Ala719,Ser696和Lys721。
