Disclosed are synthetic mucins comprising homopolymers or copolymers of
sugar and
amino acid building blocks that mimic the
structure and function of naturally-occurring mucins. Methods for their synthesis involve ring-opening
polymerization of
sugar-
amino acid conjugate monomers, optionally together with
amino acid monomers or derivatives serving as spacers or crosslinkers, followed by deprotection steps to yield tailored polymers with controlled sequence, molecular weight, and functionality. Compositions containing these synthetic mucins have utility in pharmaceutical, cosmetic, biomedical, and industrial applications such as lubricants, adhesives, moisturizers, protective coatings, and
mucus substitutes.
