Novel dual-targeted, bifunctional anti-influenza drugs formed by conjugation with anti-inflammatory agents are disclosed. Exemplary drugs according to the invention include caffeic acid (CA)-bearing zanamivir (ZA) conjugates ZA-7-CA (1), ZA-7-CA-amide (7) and ZA-7-Nap (43) for simultaneous inhibition of influenza virus neuraminidase and suppression of proinflammatory cytokines. Synthetic methods for preparation of these enhanced anti-influenza conjugate drugs are provided. The synthetic bifunctional ZA conjugates act synergistically towards protection of mice lethally infected by H1N1 or H5N1 influenza viruses. The efficacy of ZA-7-CA, ZA-7-CA-amide and ZA-7-Nap conjugates is much greater than the combination therapy of ZA with anti-inflammatory agents.
新型双靶向、双功能抗流感药物通过与抗炎药物结合形成。根据本发明的示例药物包括咖啡酸(CA)基底的扎那米韦(ZA)共轭物ZA-7-CA(1)、ZA-7-CA酰胺(7)和ZA-7-Nap(43),用于同时抑制流感病毒神经氨基酸酶和抑制促炎细胞因子。提供了用于制备这些增强型抗流感共轭药物的合成方法。合成的双功能ZA共轭物对保护由H1N1或H5N1流感病毒致命感染的小鼠具有协同作用。ZA-7-CA、ZA-7-CA酰胺和ZA-7-Nap共轭物的疗效远远优于ZA与抗炎药物的联合治疗。
