Photochemical behavior of sitafloxacin, fluoroquinolone antibiotic, in an aqueous solution.
Sitafloxacin (STFX) hydrate, an antimicrobial agent, is photo-labile in aqueous solutions. The photodegradation rates (k) in neutral solutions were higher than those observed in acidic and alkaline solutions and maximum at the maximum absorption wavelength of STFX. The structures of photodegradation products were elucidated as 7-[7-amino-5-azaspiro[2.4]heptan-5-yl]-6-fluoro-1,4-dihydro-4-oxo-3-...
متن کاملLinezolid: the first oxazolidinone antimicrobial.
Linezolid is the first of a new class of antimicrobial agents, the oxazolidinones, to be approved for clinical use in the United States and elsewhere. The drug is a totally synthetic compound, which lessens the likelihood of naturally occurring resistance mechanisms. It has excellent activity against virtually all important gram-positive pathogens, including methicillin-resistant staphylococci,...
متن کاملShort Communication Oxidation of the Novel Oxazolidinone Antibiotic Linezolid in Human Liver Microsomes
In vitro studies were conducted to identify the hepatic enzyme(s) responsible for the oxidative metabolism of linezolid. In human liver microsomes, linezolid was oxidized to a single metabolite, hydroxylinezolid (M1). Formation of M1 was determined to be dependent upon microsomal protein and NADPH. Over a concentration range of 2 to 700 mM, the rate of M1 formation conformed to first-order (non...

متن کاملIn vivo pharmacodynamics of a new oxazolidinone (linezolid).
Linezolid is a new oxazolidinone with activity against gram-positive cocci. We determined the in vivo activity of linezolid against four strains of Staphylococcus aureus (two methicillin-susceptible S. aureus [MSSA] strains and two methicillin-resistant S. aureus strains) and one penicillin-susceptible Streptococcus pneumoniae (PSSP) strain, two penicillin-intermediate S. pneumoniae strains, an...
