Page/Page column 22, (2010/11/25)
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 R5 thereof: wherein: One of A and B denotes hydrogen and the other an optionally substituted fused bicyclic heteroaryl group; and X═O or S.
