four compounds (6g, 6l, 6y and 8c) showed robust anti-influenza potencies against H5N1, H5N2 and H5N6 strains in both enzymatic assay and cellular assay. Especially, 6l was proved to possess the most potent and broad-spectrum anti-influenza activity, with IC50 values of 0.12 μM, 0.049 μM and 0.16 μM and EC50 values of 2.45 μM, 0.43 μM and 2.8 μM against H5N1, H5N2 and H5N6 strains, respectively, which
设计,合成并评估了一系列新的1,2,3-三唑奥司他韦衍生物,它们可以同时占据经典的NA催化位点和新报道的430腔,并评估其抗流感活性。结果表明,四种化合物(6g,6l,6y和8c)在酶促测定和细胞测定中均表现出针对H5N1,H5N2和H5N6菌株的强大的抗流感效力。特别是6l被证明具有最有效和最广谱的抗流感活性,针对H5N1,H5N2和H5N6菌株的IC50值为0.12μM,0.049μM和0.16μM,EC50值为2.45μM,0.43μM和2.8μM。分别比奥司他韦羧酸盐稍弱。此外,在有胚蛋模型中,在测试浓度下,6l的奥司他韦羧酸盐达到了对H9N2菌株的类似保护作用。还讨论了所选化合物的初步结构-活性关系(SAR),分子模型和计算出的理化性质。
