General description

Linezolid exhibits its activity against several Gram-positive bacteria including penicillin-resistant, methicillin-resistant, and vancomycin- resistant. Linezolid can decrease the rate of translation reaction by inhibiting the formation of initiation complex thereby reducing the length of the newly formed peptidechain. Additionally, it may also play a role in reducing the virulence leading to reduced toxins produced by Gram-positive bacteria.

Application

Se ha utilizado Linezolid para analizar las MIC (concentraciones inhibidoras mínimas) de combinaciones farmacológicas con el método del tablero de ajedrez para determinar si ivacaftor muestra interacción positiva con linezolid. Se ha utilizado para la determinación de la concentración inhibidora mínima de biopelícula y para el tratamiento de las moscas Drosophila melanogaster w118 infectadas por Mycobacterium abscessus.

Biochem/physiol Actions

Linezolid es una oxazolidinona antimicrobiana. Se une a un sitio del ARN ribosómico 23S bacteriano de la subunidad 50S y evita la formación de un complejo de iniciación 70S funcional, inhibiendo así la traducción del ARNm bacteriano. Linezolid es también un débil inhibidor no selectivo y reversible de la monoaminooxidasa.

Linezolid is an oxazolidinone antibiotic in clinical use for the treatment of serious infections of resistant Gram-positive bacteria. It inhibits protein synthesis by binding to the peptidyl transferase center on the ribosome. Almost all known resistance mechanisms involve small alterations

Antimicrobial agents and chemotherapy, 57(4), 1648-1653 (2013-01-22)
During active tuberculosis a spectrum of physiologically different Mycobacterium tuberculosis bacilli reside in human tissues. Subpopulations of the pathogen survive antibiotic treatment for a prolonged time in a dormant state of phenotypic drug resistance, a phenomenon independent of genetic mutations.
Lanqing Cui et al.
PloS one, 8(2), e57096-e57096 (2013-02-26)
Four methicillin-resistant coagulase-negative staphylococci (MRCoNS), one Staphylococcus haemolyticus and three Staphylococcus cohnii, from infections of humans collected via the Ministry of Health National Antimicrobial Resistance Surveillance Net (Mohnarin) program in China were identified as linezolid-resistant. These four isolates were negative
Binh An Diep et al.
The Journal of infectious diseases, 208(1), 75-82 (2013-03-28)
Linezolid is recommended for treatment of pneumonia and other invasive infections caused by methicillin-resistant Staphylococcus aureus (MRSA). The premise underlying this recommendation is that linezolid inhibits in vivo production of potent staphylococcal exotoxins, including Panton-Valentine leukocidin (PVL) and α-hemolysin (Hla)
Laura Morata et al.
Antimicrobial agents and chemotherapy, 57(4), 1913-1917 (2013-02-14)
Linezolid is an antibiotic with time-dependent activity, and both the percentage of time that plasma concentrations exceed the MIC and the area under the concentration-time curve over 24 h in the steady state divided by the MIC (AUC24/MIC ratio) are
