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,...

How chemical structure changes affect the curing reactions and thermal properties of 2,2 -bis(4-cyanatophenyl) propane (cyanate ester) cured rigid-rod epoxy resins has been studied for biphenol and tetramethyl biphenol epoxies. The formation of an oxazolidinone ring is the dominant curing reaction for biphenol epoxy, whereas the formation of a cyanurate ring is the dominant curing reaction for ...

The effects of a variety of oxazolidinones, with different antibacterial potencies, including linezolid, on mitochondrial protein synthesis were determined in intact mitochondria isolated from rat heart and liver and rabbit heart and bone marrow. The results demonstrate that a general feature of the oxazolidinone class of antibiotics is the inhibition of mammalian mitochondrial protein synthesi...

In the title compound, C10H9ClN2O4, the oxazolidinone ring adopts a near-planar conformation, with mean and maximum deviations of 0.0204 (8) and 0.0328 (8) Å, respectively. The nitro group is twisted slightly from the plane of the benzene ring, making a dihedral angle of 6.79 (3)°. The dihedral angle between the mean oxazolidinone plane and the benzene ring is 56.21 (3)°. In the crystal, N-H⋯O ...

Infrared irradiation promoted the Diels-Alder cycloadditions of exo-2-oxazolidinone dienes 1-3 with the Knoevenagel adducts 4-6, as dienophiles, leading to the synthesis of new 3,5-diphenyltetrahydrobenzo[d]oxazol-2-one derivatives (7, 9, 11 and 13-17), under solvent-free conditions. These cycloadditions were performed with good regio- and stereoselectivity, favoring the para-endo cycloadducts....

Staphylococcus aureus is a gram positive bacterium, responsible for both community-acquired and hospital-acquired infection, resulting in a mortality rate of 39%. 43.2% resistance to methicilin and emerging resistance to Fluroquinolone and Oxazolidinone, have evoked the necessity of the establishment of alternative and effective therapeutic approach to treat this bacteria. In this computational...

Linezolid (LZD), severed as the first oxazolidinone antibiotic, was active against multidrug-resistant gram-positive strains. LZD can induce thrombocytopenia, anemia and leukocytopenia. Currently, reports on pure red cell aplasia (PRCA) cases induced by LZD are relatively rare [4-7]. In this paper, we reported a patient with PRCA twice induced by LZD. A 37-year-old man was diagnosed with myelody...

Tuberculosis remains a growing threat of infectious diseases of twenty-first century. An attempt to find new antituberculosis agents was made especially to treat multidrug-resistant and extensively drug-resistant tuberculosis. One of the most promising drugs is bedaquiline - a new drug approved by Food and Drug Administration (FDA) and by the European Union countries. This compound is intended ...
