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. Substituents at the 4 and 5 position of the oxazolidinone direct any aldol reaction to the alpha position of the carbonyl of the substrate. [6]
Although many antibiotics work this way, the exact mechanism of action of linezolid appears to be unique in that it blocks the initiation of protein production, rather than one of the later steps. [14] As of 2014, bacterial resistance to linezolid has remained low. [15] Linezolid is a member of the oxazolidinone class of medications. [10]
2-Oxazolidinone is the parent compound of several protein synthesis inhibitor antibiotics and the Evans chiral auxiliaries for aldol reactions. Cycloserine is an antibiotic based on the 3-isoxazolidone parent.
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.
[6] [7] [8] [3] Tedizolid is a second-generation oxazolidinone derivative that is 4-to-16-fold more potent against staphylococci and enterococci compared to linezolid. [9] The recommended dosage for treatment is 200 mg once daily for a total duration of six days, either orally (with or without food) or through an intravenous injection (if ...
2‑oxazoline, 3‑oxazoline, and 4‑oxazoline (from left to right) Three structural isomers of oxazoline are possible depending on the location of the double bond, however only 2‑oxazolines are common. 4‑Oxazolines are formed as intermediates during the production of certain azomethine ylides [2] but are otherwise rare. 3‑Oxazolines are even less common but have been synthesised ...
Contezolid (trade name Youxitai) is an antibiotic of the oxazolidinone class. [1] [2] It is effective against Staphylococcus aureus, methicillin-resistant Staphylococcus aureus (MRSA), Streptococcus pyogenes, Streptococcus agalactiae, and other bacteria.
Streptogramin A is a group of antibiotics within the larger family of antibiotics known as streptogramins.They are synthesized by the bacteria Streptomyces virginiae. [1] The streptogramin family of antibiotics consists of two distinct groups: group A antibiotics contain a 23-membered unsaturated ring with lactone and peptide bonds while group B antibiotics are depsipeptides (lactone-cyclized ...
