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.
