Broad spectrum beta-lactamase inhibitors. Certain inhibitors also exhibit potent antibiotic activity in addition to beta-lactamase inhibition. Compounds of the invention are designed such that on cleavage of the beta-lactam ring reactive moieties are generated which can inactivate beta-lactamase. Also provided are methods of making beta-lactamase inhibitors and beta-lactam antibiotics exhibiting such inhibition. Additionally provided are pharmaceutical compositions for treatment or prevention of bacterial infections and methods of treatment of such infections.
广谱β-内酰胺酶抑制剂。某些
抑制剂除了抑制β-内酰胺酶外,还表现出强效的抗生素活性。本发明的化合物设计成在β-内酰胺环裂解时生成可以灭活β-内酰胺酶的反应性基团。还提供了制备β-内酰胺酶抑制剂和表现出这种抑制作用的β-内酰胺类抗生素的方法。此外还提供了用于治疗或预防细菌感染的药物组合物和治疗此类感染的方法。
