and amide domain of YQ-II-128 are important for the observed inhibitory potency on the NLRP3inflammasome. The results also identified the amide domain to incorporate polar moieties to improve solubility and potentially pharmacokinetic properties. As a result, analog 10 was identified as a selective NLRP3inhibitor with comparable potency while significantly improved aqueous solubility. Collectively

This invention relates to certain bicyclic 6-alkylidene penems which act as a inhibitor of class-D enzymes. β-Lactamases hydrolyze β-lactam antibiotics, and as such serve as the primary cause of bacterial resistance. The compounds of the present invention when combined with β-lactam antibiotics will provide an effective treatment against life threatening bacterial infections.
In accordance with the present invention there are provided compounds of general formula I or a pharmaceutically acceptable salt or in vivo hydrolyzable ester R
