The oxazolidinone linezolid inhibits initiation of protein synthesis in bacteria.
The oxazolidinones represent a new class of antimicrobial agents which are active against multidrug-resistant staphylococci, streptococci, and enterococci. Previous studies have demonstrated that oxazolidinones inhibit bacterial translation in vitro at a step preceding elongation but after the charging of N-formylmethionine to the initiator tRNA molecule. The event that occurs between these two...
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 کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولHow initiation factors tune the rate of initiation of protein synthesis in bacteria.
The kinetics of initiator transfer RNA (tRNA) interaction with the messenger RNA (mRNA)-programmed 30S subunit and the rate of 50S subunit docking to the 30S preinitiation complex were measured for different combinations of initiation factors in a cell-free Escherichia coli system for protein synthesis with components of high purity. The major results are summarized by a Michaelis-Menten scheme...
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...
