Four different classes of polyphosphazenes that can be designated as 'bioerodible' have been synthesized. In each polymer system, at least one of the side groups is hydrolytically labile. The degradation products of these reactions are phosphates, ammonia, glucose, and methylamine. The potential applications of α-D-glucosyl polyphosphazenes are of considerable interest. Drug molecules or peptides could be directly linked to the water-soluble polymer or to a crosslinked hydrogel. In vivo hydrolysis would release the glucose-bound pharmaceutical. Also, by use of a water-insolublizing cosubstituent, the potential exists to design a monlithic drug delivery system.
