2-Oxazolidinone is a heterocyclic organic compound containing both nitrogen and oxygen in a 5-membered ring. ... -3-phenylurea upon treatment with aniline ...
β-Lactam antibiotics are indicated for the prevention and treatment of bacterial infections caused by susceptible organisms. At first, β-lactam antibiotics were mainly active only against gram-positive bacteria, yet the recent development of broad-spectrum β-lactam antibiotics active against various gram-negative organisms has increased their usefulness.
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.
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 ...
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.
It is a 5-membered saturated ring with a thioether group and an amine group in the 1 and 3 positions. It is a sulfur analog of oxazolidine. Thiazolidine is a colorless liquid. Although the parent thiazolidine is only of academic interest, some derivatives, i.e., the thiazolidines, are important, such as the antibiotic penicillin.
In medicine, the Ilizarov apparatus is a type of external fixation apparatus used in orthopedic surgery to lengthen or to reshape the damaged bones of an arm or a leg; used as a limb-sparing technique for treating complex fractures and open bone fractures; and used to treat an infected non-union of bones, which cannot be surgically resolved.
In enzymology, a 3-hydroxy-2-methylpyridinecarboxylate dioxygenase (EC 1.14.12.4) is an enzyme that catalyzes the chemical reaction. 3-hydroxy-2-methylpyridine-5-carboxylate + NAD(P)H + H + + O 2 2-(acetamidomethylene)succinate + NAD(P)+
