  • Patent number: 6235720
    Abstract: The present invention includes polymerizable monomers comprising an acid-functionalized glycoside moiety. The monomer can have 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 pendant acid-functionalized glycoside moieties. The present invention also provides a method for treating a microbial infection in a mammal by administering to the mammal a therapeutically effective amount of a polymer comprising one or more acid-functionalized glycoside moieties.
