“Background Individuals whose immune activity has been compromised by conditions, such as cancer, transplantation, blood dialysis, and aging often become infected with Staphylococcus aureus. Particularly problematic is infection by methicillin-resistant S. aureus (MRSA), SCH772984 order for which antibiotic chemotherapy is often difficult and results
in failure because this organism shows resistance to structurally and functionally diverse chemotherapeutic agents. Spread of MRSA was limited to hospital patients for a long period of time, but it has become more common in the broader community in recent years. Owing to the multi-antibiotic-resistant nature of MRSA, only a limited range of chemotherapeutic agents can be used; most commonly, vancomycin or the recently developed linezolid [1–3]. Vancomycin is a glycopeptide antibiotic with a molecular mass of 1449.3. It binds with the d-Ala-d-Ala terminals of the peptidoglycan structure and its precursors, and blocks the action of peptidoglycan transpeptidase or penicillin-binding proteins (PBPs), consequently http://www.selleck.co.jp/products/MDV3100.html inhibiting extension of the peptidoglycan network and growth of the cells [4, 5]. Vancomycin is active against Gram-positive bacteria including enterococci and staphylococci , whereas it is ineffective against Gram-negative bacteria, mainly because the outer membrane acts as a penetration barrier. Another problem in MRSA-infected patients is co-infection with Gram-negative bacteria, such as Pseudomonas aeruginosa, which is naturally resistant to vancomycin and linezolid. One of the solutions for the chemotherapy of such mixed infections has been to use a combination of vancomycin and ß-lactam antibiotics .
