By complexing glucose and other mono- and disaccharides with phenylboronic acid, they were solubilized in many organic solvents. Pseudomonas sp. lipoprotein lipase readily acylated such solubilized sugars in these solvents (no reaction was observed without phenylboronic acid, i.e., when sugars are insoluble in the reaction medium). Solubilized D-glucose was enzymatically acylated with vinyl acrylate on a preparative scale, and the resultant 6-O-acryloylglucose was chemically polymerized to yield a sugar-based polyacrylate with a molecular weight of 14,000 Da.

Oral ulcer wounds are difficult to heal due to bacterial infections, persistent inflammatory responses, and excessive reactive oxygen species (ROS). Therefore, the elimination of bacteria, removal of ROS, and reduction of inflammation are prerequisites for the treatment of mouth ulcer wounds. In this study, oligomeric proanthocyanidins (OPC) and 3-(aminomethyl)phenylboronic acid-modified hyaluronic acid (HP) were used to form polymer gels through dynamic covalent borate bonds.

Nanohybrids combining phenylboronic acid-modified carbon dots (PCDs) and proteinase K have been engineered for addressing the formidable challenges of antimicrobial photodynamic therapy (aPDT) against bacterial biofilm infections, overcoming biofilm barrier obstruction, the limited diffusion of reactive oxygen species (ROS), and the inadequate ROS generation of traditional photosensitizers. PCDs are formulated for superior water solubility and robust singlet oxygen (O) production, mitigating issues related to dispersion and aggregation-induced quenching typical of conventional photosensitizers. The conjugation of phenylboronic acid to CDs not only enhanced O generation through increased electron-hole separation but also imparted strong bacterial binding capabilities to the PCDs, enabling broad-spectrum sterilization by maximizing the ROS-mediated bacterial destruction.

Excessive oxidative stress and persistent inflammation are key factors contributing to the formation of diabetic chronic wounds. Delivering antioxidants through a microenvironment-responsive hydrogel system can effectively enhance wound healing and tissue regeneration. In this study, we developed a novel pH- and glucose-responsive hydrogel using Schiff base reaction and phenyl borate group for intelligent antioxidant release.

A series of biodegradable nanoparticle-based drug delivery systems have been designed utilizing poly(β-amino ester)-guanidine-phenylboronic acid (PBAE-G) polymers. In this study, a novel Lentinan-Functionalized PBAE-G-nanodiamond system was developed to carry ovalbumin (LNT-PBAE-G-ND@OVA). The impact of this drug delivery system on the activation and maturation of macrophages was then assessed.

Objective: This study utilized three cell lines: normal prostate epithelial RWPE-1, androgen-dependent LNCaP, and androgen-independent PC3. We investigated the inhibitory effects of phenylboronic acid (PBA)'s inhibitory effect on cellular proliferation due to its ability to disrupt microtubule formation in prostate cancer cell lines. Additionally, this study aimed to assess the cytotoxic effects of PBA on prostate cancer cells using twodimensional (2D) and three-dimensional (3D) cell culture models.
