A series of novel 4-[5-(substituted-1,2,4-oxadiazol-3-yl)phenylamine] derivatives at C-4 position of 6,7-dimethoxy-quinazolines were synthesized through multistep synthesis. The new compounds were tested for inhibition of vascular endothelial growth factor receptor II (VEGFR-2). Many compounds display VEGFR-2 inhibitory activity with an IC50 as low as 0.017 μM in an HTRF enzymatic assay. Compound 8j exhibited good antibacterial activity by inhibiting the growth of methicillin-sensitive Staphylococcus aureus (MSSA), methicillin-resistant Staphylococcus aureus (MRSA) and ATCC 35218 Escherichia coli (MIC: 0.25-16.00 μg/mL).
一系列新颖的6,7-二甲氧基喹唉类4-[5-(取代-1,2,4-噁二唑-3-基)苯胺]衍生物在C-4位置通过多步合成合成。这些新化合物被测试为血管内皮生长因子受体II(VEGFR-2)的抑制剂。许多化合物显示出VEGFR-2抑制活性,在HTRF酶活性测定中IC50低至0.017 μM。化合物8j表现出良好的抗菌活性,通过抑制甲氧西林敏感金黄色葡萄球菌(MSSA)、甲氧西林耐药金黄色葡萄球菌(MRSA)和美国菌种收藏35218大肠杆菌(MIC:0.25-16.00 μg/mL)的生长。
