The resistance of bacteria against ${\beta}$-lactam antibiotics is mainly caused by the production of ${\beta}$-lactamase enzymes. ${\beta}$-Lactamase inhibitors are used in combination with known antibiotics to overcome the growing problem of bacterial resistance. We prepared 6-(thienylmethylene)penam sulfones for the development of potent ${\beta}$-lactamase inhibitors and evaluated their ${\beta}$-lactamase inhibitory activities.
