WebMar 16, 2024 · We previously showed that attaching two fluorophenylboronic acid (FPBA) residues to the C-terminal B chain of insulin glargine led to glucose-dependent solubility. Herein, we demonstrated that relocating FPBA from B chain to A chain increased the baseline solubility without affecting its potency. WebPolymerizing reduced graphene oxide with PBA and its derivatives can render glucose- and light-responsiveness to the glucose, and the reduced graphene oxide functionalized with phenylboronic acid can be used as a sensor for glucose sensing and detection of the glucose molecule in the human body. 71 For example, Basiruddin et al 72 used PBA ...
WebIn this study, we synthesized a new monomer, namely, 3,4-ethylenedioxythiophene bearing a fluoro-containing phenylboronic acid (EDOT–FPBA) for enzyme-free glucose sensing at physiological conditions. The EDOT–FPBA monomer is electropolymerized on a glassy carbon electrode (poly (EDOT–FPBA)/GCE) at a constant voltage. WebIn 1995, Shinkai’s group synthesized phenyl(di)boronic acid (PDBA), a fluorescent probe selective for glucose. The ortho-aminomethylphenylboronic acid unit of PDBA can recognize glucose under physiological conditions because the ortho-position of the phenylboronic acid incorporates an aminomethyl, and the pK a of PDBA was reduced to 4.8 ...
