The present invention includes polymerizable monomers comprising an acid-functionalized glycoside moiety. In one embodiment, the monomer has a polymerizable functional group, such as an olefinic bond, to which the acid-functionalized glycoside moiety is attached by a spacer group, for example, an alkylene group, or an alkylene group wherein one or more carbon atoms are substituted by heteroatoms, such as oxygen, nitrogen or sulfur atoms. The present invention also includes polymers comprising one or more acid-functionalized glycoside moieties, such as pendant acid-functionalized glycoside moieties, which can inhibit or prevent rotavirus infection in a mammal. Such a polymer can comprise, for example, a monomer of the present invention. The polymer can be a homopolymer or a copolymer, and can have, for example, a polyacrylamide, polyacrylate or polystyrene backbone. In another embodiment, the present invention comprises a method for treating a rotaviral infection in a mammal, for example, a human, by administering to the mammal a therapeutically effective amount of a polymer comprising one or more glycoside moieties, such as pendant glycoside moieties. The polymer can be a homopolymer or a copolymer. In one embodiment, the polymer is a copolymer which comprises an acid-functionalized glycoside-bearing monomer and acrylamide.
本发明包括聚合物化单体,其中包括含有酸官能化糖苷基团的单体。在一种实施例中,该单体具有可聚合的官能基团,例如烯丙基键,酸官能化糖苷基团通过间隔基团连接到该官能基团,例如烷基基团,或者其中一个或多个碳原子被杂原子取代的烷基基团,例如氧、氮或硫原子。本发明还包括聚合物,其中包括一个或多个酸官能化糖苷基团,例如挂链酸官能化糖苷基团,可以抑制或预防哺乳动物中的轮状病毒感染。这样的聚合物可以包括本发明的单体。该聚合物可以是均聚物或共聚物,例如可以具有聚丙烯酰胺、聚丙烯酸酯或聚苯乙烯骨架。在另一实施例中,本发明包括一种治疗哺乳动物,例如人类,轮状病毒感染的方法,通过向哺乳动物投与包括一个或多个糖苷基团的聚合物的治疗有效量。该聚合物可以是均聚物或共聚物。在一种实施例中,该聚合物是一种共聚物,其中包括一个酸官能化糖苷基团单体和丙烯酰胺。
