A series of substituted aryl glycoside analogues of gastrodin have been identified as potential anti-influenza agents. The most potent inhibitor 1a exhibited moderate inhibitory activity against the A/Hanfang/359/95(H3N2) and A/FM/1/47(H1N1) strains of the influenza A virus (IC50 values of 44.40 and 34.45 μM, respectively) and the oseltamivir-null B/Jifang/13/97 strain of influenza B (IC50 value of 33.01 μM). In this article, multiple doses of compound 1a (80 mg/kg/day, oral administration) were used for the treatment of mice infected with influenza A/FM/1/47-MA (H1N1), and surprisingly we found that compound 1a significantly increased the number of survivors and prolonged the mean survival time. The preliminary studies on the mechanism of antiviral activity showed no interaction between compound 1a and the neuraminidase or the M2 protein. The novel target to overcome drug resistance combined with its good in vivo profile support compound 1a to be a new lead for further development of antiviral agents.
一系列取代天麻素的芳基糖苷类似物已被确认为潜在的抗流感药物。最有效的抑制剂 1a 对甲型流感病毒的 A/Hanfang/359/95(H3N2) 株和 A/FM/1/47(H1N1) 株(IC50 值分别为 44.40 和 34.45 μM)以及奥司他韦无效的乙型流感病毒的 B/Jifang/13/97 株(IC50 值为 33.01 μM)具有中等抑制活性。本文采用多剂量化合物 1a(80 毫克/千克/天,口服)治疗感染甲型/乙型/丙型流感(H1N1)的小鼠,结果令人惊讶地发现,化合物 1a 能显著增加存活人数并延长平均存活时间。对抗病毒活性机制的初步研究表明,化合物 1a 与神经氨酸酶或 M2 蛋白之间没有相互作用。化合物 1a 克服耐药性的新靶点及其良好的体内特征支持其成为进一步开发抗病毒药物的新线索。
