Description and Uses
Phenylboronic acid and its derivatives form complexes with polyol compounds such as saccharides and poly(vinyl alcohol) (PVA). Glucose-sensitive hydrogels can be prepared by using phenylhoronic acid as a ligand for target glucose. For example. a copolymer with phenylboronic acid moieties was synthesized by copolymerization of 4V-vinyl-2-pyrrolidone (NVP) and 3-(acryl- amide)phcnylhoronic acid (PBA). The complexes between the NVP-PBA copolymer and PVA enable us to construct glucose-sensitive insulin release systems because the complexes dissociated in response to the glucose concentration.
This phenylboronic acid is soluble in water and the coupling reaction can even be carried out in water. It is compatible with many organic substituents such as esters, ketones, alcohols, etc. which would prohibit the use of Grignard reagents in coupling reactions.
