  ENHANCED ANTI-INFLUENZA AGENTS CONJUGATED WITH ANTI-INFLAMMATORY ACTIVITY

  摘要：

  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。

  Influenza therapy with a single targeted compound is often limited in efficacy due to the rapidly developed drug resistance. Moreover, the uncontrolled virus-induced cytokines could cause the high mortality of human infected by H5N1 avian influenza virus. In this study, we explored the novel dual-targeted bifunctional anti-influenza drugs formed by conjugation with anti-inflammatory agents. In particular, the caffeic acid (CA)-bearing zanamivir (ZA) conjugates ZA-7-CA (1) and ZA-7-CA-amide (7) showed simultaneous inhibition of influenza virus neuraminidase and suppression of pro-inflammatory cytokines. These ZA conjugates provided remarkable protection of cells and mice against influenza infections. Intranasal administration of low dosage (<1.2 mu mol/kg/day) of ZA conjugates exhibited much greater effect than the combination therapy with ZA and the anti-inflammatory agents in protection of the lethally infected mice by H1N1 or H5N1 influenza viruses.

  Zanamivir (ZA) is a potent anti-influenza drug, but it cannot be administrated orally because of the hydrophilic carboxylate and guanidinium groups. Guanidino-oseltamivir (GO) is another effective neuraminidase inhibitor with polar guanidinium group under physiological conditions. The ester prodrugs ZA-HNAP (5) and GO-HNAP (6) were prepared to incorporate a 1-hydroxy-2-naphthoic (HNAP) moiety to attain good lipophilicity in the intramolecular ion-pairing forms. ZA-HNAP resumed high anti-influenza activity (EC(50) = 48 nM), in cell-based anti-influenza assays, by releasing zanamivir along with nontoxic HNAP. Under similar conditions, the hydrolysis of the GO-HNAP ester was too sluggish to show the desired anti-influenza activity. (C) 2011 Elsevier Ltd. All rights reserved.
