A novel type of quinazoline derivatives, which were designed by the combination of quinazoline as the backbone and oxazole scaffold as the substituent, have been synthesized and their biological activities were evaluated for anti‐proliferative activities and EGFR inhibitory potency. Compound 12b demonstrated the most potent inhibitory activity (IC50=0.95 µmol/L for EGFR), which could be optimized as
以喹唑啉为骨架,恶唑骨架为取代基,设计合成了一种新型的喹唑啉衍生物,并对其生物学活性进行了抗增殖活性和EGFR抑制能力的评价。化合物12b表现出最强的抑制活性(对EGFR的IC 50 = 0.95 µmol / L),可以在进一步的研究中将其优化为潜在的EGFR抑制剂。合成的喹唑啉类似物和所有中间体的结构通过1 H和13 C NMR,2D NMR光谱,IR光谱和MS光谱确认。
