Webacids, because most boronic acid containing drugs are alkyl, not aryl boronic acids. First, this series of experiments shows that a similar drop in pKa occurs, roughly 3 units or greater for the highest binding polyols, when alkyl or aryl boronic acids form boronate esters. Second, the rank order of the polyols’ effect is maintained. WebJul 5, 2024 · Boronic acids as mild electrophiles are also investigated as reversible covalent inhibitors (9, 10), and thousands of different building blocks are now commercially available. As a result, boronic acids are increasingly being seen in approved drugs, e.g., vaborbactam or bortezomib (Fig. 1, A and B) (11, 12).
