Abstract
β-lactam antibiotics have been the most widely used drug of choice to combat infectious disease caused by bacteria. Unfortunately, their effectiveness is drastically threatened by bacterial β-lactamases. β-lactamases is responsible for the resistance to most antibiotic drugs. For decades, β-lactam β-lactamases inhibitors have been used to reduce bacterial resistance; however, in this study 1,2,4-oxadiazolidinone derivatives as a non-β-lactam β-lactamases inhibitor against TEM-1 and P99 β-lactamases. The significance of oxadiazolidinone is the prominent five-membered ring scaffold in its structure, which is configurationally stable and present in other biologically active compounds such as linezolid and avibactam. Oxadiazolidinones were synthesized by treating nitrones with isocyanates. The synthesized compounds were characterized using 1H and 13C NMR, GC-MS, and FTIR. Afterward, they were tested using Nitrocefin as substrate to determine their effectiveness against TEM-1 and P99 serine β-lactamase. Compound 2a-2c, and 3 showed inhibition ranging from 12-38%.
