Boronic acid inhibitors of the class A β-lactamase KPC-2

Add time:08/16/2019    Source:sciencedirect.com

The rapid rise of antimicrobial resistance is one of the greatest challenges currently facing medical science. The most common cause of resistance to β-lactam antibiotics is the expression of β-lactamase enzymes, such as KPC-2. As such the development of novel inhibitors of KPC-2 and related enzymes is of the upmost importance. We report the design and synthesis of novel boronic acid transition state analogs containing a 1,4-substituted 1,2,3-triazole linker based on the known inhibitor 3-nitrophenyl boronic acid and demonstrate that they are promising scaffolds for the development inhibitors of KPC-2 with the ability to recover sensitivity to the antibiotic cefotaxime.
