Oxazolidinone is a five-member heterocyclic ring exhibiting potential medicinal properties with preferential antibacterial activity. Scientists reported various synthetic procedures for this heterocyclic structure. Current review articles tried to cover each and every potential aspect of oxazolidinone like synthetic routes, pharmacological mechanism of action, medicinal properties, and current ...

Radezolid (RAD, 12), biaryl oxazolidinone, was synthesised with small modifications according to the methods described in the literature. The pharmacological activity is observed only for (S)-enantiomer, therefore its synthesis is oriented towards obtaining a single isomer of required purity and desired optical configuration. The intermediate products of RAD synthesis were characterised using 1...

syn-1,2-Amino alcohols are prevalent motifs in a diverse range of important small molecules such as natural products, pharmaceuticals, and asymmetric catalysts. The majority of methods for selectively constructing 1,2-amino alcohols rely on functional group interconversions or C-C bond-forming reactions using preoxidized materials.1 Selective methods for directly installing nitrogen functionali...

in recent years there has been considerable interest in the synthesis and separation of enantiomers of organic compounds especially because of their importance in the biochemistry and pharmaceutical industry. high-performance liquid chromatography is a very useful method for the direct separation of enantiomers. however, about 30−40 years ago, commercially available chiral stationary phases wer...

Following recent reports of ribosomal protein L3 mutations in laboratory-derived linezolid-resistant (LZD(r)) Staphylococcus aureus, we investigated whether similar mutations were present in LZD(r) staphylococci of clinical origin. Sequence analysis of a variety of LZD(r) isolates revealed two L3 mutations, DeltaSer145 (S. aureus NRS127) and Ala157Arg (Staphylococcus epidermidis 1653059), both ...
