This invention relates to certain tricyclic 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 formula I which are useful for treatment of bacterial infections having class-D enzymes associated therewith:
wherein: One of A and B denotes hydrogen and the other an optionally substituted fused tricyclic heteroaryl group; and X is S or O.
这项发明涉及某些三环6-烷基亚胺基青霉素,其作为类D酶的抑制剂。β-内酰胺酶水解β-内酰胺类抗生素,因此是细菌抗药性的主要原因。本发明的化合物与β-内酰胺类抗生素结合时,将提供一种有效治疗危及生命的细菌感染的方法。根据本发明,提供了以下公式I的化合物,其用于治疗与类D酶相关的细菌感染:其中:A和B中的一个表示氢,另一个表示可选择取代的融合三环杂芳基团;X为S或O。
