Antiviral compositions containing one or more antiviral agents coupled to a polymer and methods of making and using the compositions, are described herein. The one or more antiviral agents are covalently coupled to the polymer, and thereby prevent or decrease development of drug resistance. In some embodiments, the polymer is a biodegradable polymer. In particular embodiments, the polymer is a water-soluble, biodegradable polymer, which has an overall neutral charge (e.g., no charged groups or overall neutral charge). In a more particular embodiment, the neutral polymer is polyglutamine or a polymer having properties similar to polyglutamine, polyaspartate, and other homopolypeptides that can be modified to have no charge or no net charge. The compositions described herein are effective at treating a variety of viral infections, such as influenza, respiratory syncythial virus, rhinovirus, human metaneumovirus, and other respiratory diseases, while inhibiting or preventing the development of resistance.
A conjugate comprising one or more neuraminidase inhibitors covalently coupled to one or more water-soluble, biodegradable polymers, wherein the one or more neuraminidase inhibitors are bound to the polymer via a carbamate linkage, the conjugate exhibits at least a 10 fold greater inhibition of sialidase than free neuraminidase inhibitor, the conjugate does not does not inhibit colloid interaction as determined by the hemagglutination assay, or combinations thereof.
