The incorporation of a gem-dimethyl group at the 5-position of a chiral oxazolidinone biases the conformation of the adjacent C(4)-stereodirecting group such that the gem-dimethyl-4-iso-propyl combination mimics a C(4)-tert-butyl group, providing higher levels of stereocontrol than a simple 4-iso-propyloxazolidinone. The generality of this principle is demonstrated with applications in stereose...

MRX-I is a potent oxazolidinone antibiotic against Gram-positive pathogens, including methicillin-resistant Staphylococcus aureus (MRSA), penicillin-resistant Streptococcus pneumoniae (PRSP), penicillin-intermediate S. pneumoniae (PISP), and vancomycin-resistant enterococci (VRE). In this study, the in vivo efficacy of orally administered MRX-I was evaluated using linezolid as a comparator. MRX...

Linezolid is an oxazolidinone antibiotic with activity against gram-positive organisms, particularly methicillin-resistant Staphylococcus aureus (MRSA). To the best of our knowledge, there are only two case reports on rhabdomyolysis in patients treated with linezolid. Here, we describe two cases of serious rhabdomyolysis: one in a patient with septic community-acquired (CA)-MRSA pneumonia and a...

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...

The nitrofuran antimicrobial agent, furazolidone (FZ), is still used in veterinary medicine in some countries in the Middle and Far Eastern countries. The present study aimed to investigate the effects of successive bolus doses of FZ and its metabolite 3-amino-2-oxazolidinone (AOZ) on cytochrome P450 (CYP)-related activities in the livers of rats and chickens. Female Wistar rats and white Legho...

A combined experimental and theoretical study shows how the interaction of VUV radiation with cyclo-(alanine-alanine), one 2,5-diketopiperazines (DKPs), produces reactive oxazolidinone intermediates. The simulations reveal that these intermediates other neutral charged fragments, released in molecular decomposition, leads either to reconstruction cyclic dipeptide or formation longer linear pept...

The activity of Rivaroxoban oxazolidinone series against Mycobacterium terrae was investigated in silico and vitro. In studies have shown a high binding affinity Rivaroxaban to β-ketoacyl[ACP]synthase I that plays key role the biosynthesis mycolic acids, being components mycobacterial cell wall. molecular docking study, two main sites with protein were predicted evaluated: minimum energies foun...

A method was developed for simultaneous qualitative and quantitative analysis of five metabolites of nitrofuran antibiotics, including 3-amino-2-oxazolidinone (AOZ), 5-morpholino-methyl-3-amino-2-oxazolidinone ( AMOZ ), semicarbazide ( SEM ), 1-aminohydantoin (AHD) and 3, 5-dinitrosalicylic acid hydrazide (DNSH) in aquatic products by liquid chromatography-tandem mass spectrometry (LC-MS/MS). T...
