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,还具有很强的抗生素活性。本发明的化合物设计成在β-内酰胺环裂解时产生活性分子,可使β-内酰胺酶失活。本发明还提供了制造β-内酰胺酶抑制剂的方法和具有这种抑制作用的β-内酰胺类抗生素。此外,还提供了用于治疗或预防细菌感染的药物组合物以及治疗此类感染的方法。
