Interactions of oritavancin, a new semi-synthetic lipoglycopeptide, with lipids extracted from Staphylococcus aureus.
Oritavancin, a lipoglycopeptide with marked bactericidal activity against vancomycin-resistant Staphylococcus aureus and enterococci, induces calcein release from CL:POPE and POPG:POPE liposomes, an effect enhanced by an increase in POPG:POPE ratio, and decreased when replacing POPG by DPPG (Domenech et al., Biochim Biophys Acta 2009; 1788:1832-40). Using vesicles prepared from lipids extracted...
متن کاملOritavancin: a novel lipoglycopeptide active against Gram-positive pathogens including multiresistant strains.
Oritavancin is a lipoglycopeptide antibiotic under investigation for the treatment of serious infections caused by Gram-positive bacteria. Oritavancin has demonstrated rapid dose-dependent bactericidal activity towards vancomycin-susceptible and -resistant enterococci, meticillin-susceptible and -resistant Staphylococcus aureus, vancomycin-intermediate S. aureus (VISA), heteroresistant VISA (hV...
متن کاملSecnidazole. A 5-nitroimidazole derivative with a long half-life.
The therapeutic activity of a single 2 g dose of secnidazole was studied in patients with urogenital trichomoniasis. In 140 patients, 97% were cured and the drug was well tolerated. In the laboratory, tests on sensitivity were made and the minimal inhibitory concentration (MIC) and the minimal trichomonacidal concentration (MTC) were determined on cultures that had recently been isolated at the...

Oritavancin (Orbactiv): a new-generation lipoglycopeptide for the treatment of acute bacterial skin and skin structure infections.
متن کاملMacrophage killing of bacterial and fungal pathogens is not inhibited by intense intracellular accumulation of the lipoglycopeptide antibiotic oritavancin.
Intact phagocytic effector function is fundamental to host defense against microbial pathogens. Concern has been raised regarding the potential that accumulation of certain agents, including cationic amphiphilic antibiotics, within macrophages could cause a mixed-lipid storage disorder, resulting in macrophage dysfunction in recipients. The ability of 2 macrophage cell lines (HL-60; RAW 264.7) ...
