Boronate-containing polymers form affinity complexes with mucin and enable tight and reversible occlusion of mucosal lumen by poly (vinyl alcohol) gel
Author
Summary, in English
Copolymers of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with N,N-dimethylarcrylamide (DMAA) formed insoluble interpolymer complexes with mucin from porcine stomach at pH 9.0. The complex formation based on boronate-sugar interactions took place between the similarly charged macromolecules and resulted in coacervate particles formation, which depended both on pH and ionic strength of the solution. the coacervation rate displayed a maximum at the intermediate DMAA_NAAPBA copolymer: mucin weight ratio, that is a pattern typical of interpolymer complex formation.
