使用空斑减少测定和与病毒神经氨酸酶 (NA) 的结合亲和力检查共价连接到聚 L-谷氨酰胺的商业药物扎那米韦 (Relenza™) 对甲型流感病毒感染性的影响。这些多价药物缀合物表现出 (i) 与扎那米韦母体相比,针对人类和禽类病毒株(包括野生型和耐药突变体)的抗流感效力提高了 20,000 倍,以及 (ii) 优异的神经氨酸酶 (NA) 抑制常数,特别是对于突变体。这些发现为探索聚合物附着的抑制剂作为更有效的治疗方法,特别是针对耐药流感病毒株提供了基础。
Effects of the commercial drug zanamivir (Relenza™) covalently attached to poly-l-glutamine on the infectivity of influenza A viruses are examined using the plaque reduction assay and binding affinity to viral neuraminidase (NA). These multivalent drug conjugates exhibit (i) up to a 20,000-fold improvement in anti-influenza potency compared with the zanamivir parent against human and avian viral strains, including both wild-type and drug-resistant mutants, and (ii) superior neuraminidase (NA) inhibition constants, especially for the mutants. These findings provide a basis for exploring polymer-attached inhibitors as more efficacious therapeutics, particularly against drug-resistant influenza strains.
