Oxazolidinones are useful as Evans auxiliaries, which are of interest for chiral synthesis. In a common implementation, an acid chloride substrate reacts with a chiral oxazolidinone to form an imide .
The oxazolidones and isoxazolidones are a set of six isomeric five-membered heterocyclic compounds consisting of a carbonyl group, an oxygen atom, a nitrogen atom with a hydrogen atom attached, and two methylene groups.
Oxazolidine is a five-membered heterocycle ringwith the formula (CH 2) 3 (NH)O.The O atom and NH groups are not mutually bonded, in contrast to isoxazolidine. [2] [3] Oxazolidines (emphasis on plural) are derivatives of the parent oxazolidine owing to the presence of substituents on carbon and/or nitrogen.
The antimicrobial spectrum of an antibiotic can be determined by testing its antimicrobial activity against a wide range of microbes in vitro. Nonetheless, the range of microorganisms which an antibiotic can kill or inhibit in vivo may not always be the same as the antimicrobial spectrum based on data collected in vitro. [2] [5]
The oxazolidinone pharmacophore—the chemical "template" essential for antimicrobial activity—consists of a 1,3-oxazolidin-2-one moiety with an aryl group at position 3 and an S-methyl group, with another substituent attached to it, at position 5 (the R-enantiomers of all oxazolidinones are devoid of antibiotic properties). [108]
[1] [9] The results of antimicrobial susceptibility tests performed during a given time period can be compiled, usually in the form of a table, to form an antibiogram. [31] [32] Antibiograms help the clinician to select the best empiric antimicrobial therapy based on the local resistance patterns until the laboratory test results are available ...
Glycopeptide antibiotics are a class of drugs of microbial origin that are composed of glycosylated cyclic or polycyclic nonribosomal peptides.Significant glycopeptide antibiotics include the anti-infective antibiotics vancomycin, teicoplanin, telavancin, ramoplanin, avoparcin and decaplanin, corbomycin, complestatin and the antitumor antibiotic bleomycin.
Cefdinir, sold under the brand name Omnicef among others, is an antibiotic used to treat pneumonia, otitis media, strep throat, and cellulitis. [1] It is a less preferred option for pneumonia, otitis media, and strep throat which may be used in those with a severe penicillin allergy . [ 1 ]
