A series of 7,8‐bis(methoxymethyl)‐7,8‐dihydro‐[1,4]dioxino[2,3‐g]quinazolines were prepared and evaluated for their inhibition of phosphorylation of the isolated epidermal growth factor receptor (EGFR) enzyme and for their growth inhibition of the A431 cell line. Among them, compound 3c having a 3‐iodophenyl ring was most potent (IC50 = 1.66 nM) against the isolated EGFR enzyme and also showed meaningful
制备了一系列 7,8-双(甲氧基甲基)-7,8-二氢-[1,4] 二恶英 [2,3-g] 喹唑啉并评估了它们对分离的表皮生长因子受体 (EGFR) 磷酸化的抑制作用) 酶及其对 A431 细胞系的生长抑制。其中,具有 3-碘苯环的化合物 3c 对分离的 EGFR 酶最有效(IC50 = 1.66 nM),并且对 A431 细胞系也显示出有意义的效力(GI50 = 1.99 μM),尽管低于 PD153035(GI50 = 1.03微米)。然而,与其报告的数据相比,作为厄洛替尼 (TarcevaTM) 的精确刚性类似物的化合物 3e 不如原始化合物。
