Hydrogel-Encapsulated Biofilm Inhibitors Abrogate the Cariogenic Activity of .

We designed and synthesized analogues of a previously identified biofilm inhibitor to improve solubility, retain inhibitory activities, and to facilitate encapsulation into pH-responsive hydrogel microparticles. The optimized lead compound showed improved solubility of 120.09 μg/mL, inhibited biofilm with an IC value of 6.
