Ceftobiprole is a novel broad-spectrum cephalosporin that binds with high affinity to PBP 2a, the methicillin-resistance determinant of staphylococci, and is active against methicillin- and vancomycin-resistant Staphylococcus aureus. Ceftobiprole was compared to vancomycin in a rabbit model of methicillin-resistant S. aureus aortic valve endocarditis. Ceftobiprole and vancomycin were equally effective against endocarditis caused by methicillin-resistant S. aureus strain 76, whereas ceftobiprole was more effective than vancomycin against the vancomycin-intermediate S. aureus strain HIP5836. The activity of ceftobiprole against drug-resistant strains of S. aureus warrants its further clinical development.
头孢比普是一种新型广谱头孢菌素,它与葡萄球菌的耐甲氧西林决定因子PBP 2a具有高亲和力结合,并且对耐甲氧西林和耐万古霉素的金黄色葡萄球菌具有活性。在耐甲氧西林金黄色葡萄球菌主动脉瓣心内膜炎的兔模型中,对头孢比普和万古霉素进行了比较。头孢比普和万古霉素对耐甲氧西林金黄色葡萄球菌菌株76引起的心内膜炎同样有效,而头孢比普对万古霉素中介的金黄色葡萄球菌菌株HIP5836比万古霉素更有效。头孢比普对金黄色葡萄球菌耐药菌株的活性值得进一步进行临床开发。
