    • The present invention includes polymerizable monomers comprising a fucoside moiety. In one embodiment, the monomer has a polymerizable functional group, such as an olefinic bond, to which the fucoside 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 fucoside moieties, such as pendant fucoside 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 rotavirus 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 glycoside moieties can be, for example, fucoside moieties or sialic acid moieties. The polymer can be a homopolyrner or a co-polymer. In one embodiment, the polymer is a copolymer comprising a glycoside-bearing monomer and a hydrophobic monomer. In another embodiment, the polymer to be administered comprises two or more different glycoside-bearing monomers.
    • 本发明包括包含岩藻糖苷部分的可聚合单体。 在一个实施方案中,单体具有可聚合官能团,例如烯键,通过间隔基团例如亚烷基或其中一个或多个碳原子被 杂原子,例如氧,氮或硫原子。 本发明还包括包含一种或多种可以抑制或预防哺乳动物轮状病毒感染的岩藻糖苷部分的聚合物,例如侧壁ucoside部分。 这样的聚合物可以包括例如本发明的单体。 聚合物可以是均聚物或共聚物,并且可以具有例如聚丙烯酰胺,聚丙烯酸酯或聚苯乙烯主链。 在另一个实施方案中,本发明包括通过向哺乳动物施用治疗有效量的包含一个或多个糖苷部分的聚合物,例如侧链糖苷部分,来治疗哺乳动物例如人的轮状病毒感染的方法。 糖苷部分可以是例如岩藻糖苷部分或唾液酸部分。 聚合物可以是均聚物或共聚物。 在一个实施方案中,聚合物是包含含糖苷单体和疏水性单体的共聚物。 在另一个实施方案中,待施用的聚合物包含两种或更多种不同的含糖苷单体。
