Oxazolidinone
2-Oxazolidone is a heterocyclic organic compound containing both nitrogen and oxygen in a 5-membered ring. Oxazolidinones Evans auxiliaries Oxazolidinones are a class of compounds containing 2-oxazolidone in the structure. In chemistry, they are useful as Evans auxiliaries, which are used for chiral synthesis. Usually, the acid chloride substrate reacts with the 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. Pharmaceuticals Oxazolidinones are mainly used as antimicrobials. The antibacterial effect of oxazolidinones is by working as protein synthesis inhibitors, targeting an early step involving the binding of N-formylmethionyl-tRNA to the ribosome. (See Linezolid#Pharmacodynamics) Some of the most important oxazolidinones are antibiotics. Examples of antibiotic oxazolidinones include: *Linezolid (Zyvox), which is available for intravenous administratio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linezolid
Linezolid is an antibiotic used for the treatment of infections caused by Gram-positive bacteria that are resistant to other antibiotics. Linezolid is active against most Gram-positive bacteria that cause disease, including streptococci, vancomycin-resistant enterococci (VRE), and methicillin-resistant ''Staphylococcus aureus'' (MRSA). The main uses are infections of the skin and pneumonia although it may be used for a variety of other infections including drug-resistant tuberculosis. It is used either by injection into a vein or by mouth. When given for short periods, linezolid is a relatively safe antibiotic. It can be used in people of all ages and in people with liver disease or poor kidney function. Common side effects with short-term use include headache, diarrhea, rash, and nausea. Serious side effects may include serotonin syndrome, bone marrow suppression, and high blood lactate levels, particularly when used for more than two weeks. If used for longer periods it ...

Aldol Reaction
The aldol reaction is a means of forming carbon–carbon bonds in organic chemistry. Discovered independently by the Russian chemist Alexander Borodin in 1869 and by the French chemist Charles-Adolphe Wurtz in 1872, the reaction combines two carbonyl compounds (the original experiments used aldehydes) to form a new β-hydroxy carbonyl compound. These products are known as ''aldols'', from the ''ald''ehyde + alcoh''ol'', a structural motif seen in many of the products. Aldol structural units are found in many important molecules, whether naturally occurring or synthetic. For example, the aldol reaction has been used in the large-scale production of the commodity chemical pentaerythritol and the synthesis of the heart disease drug Lipitor (atorvastatin, calcium salt). The aldol reaction unites two relatively simple molecules into a more complex one. Increased complexity arises because up to two new stereogenic centers (on the Alpha carbon, α- and β-carbon of the aldol adduct, mar ...

Tedizolid
Tedizolid (formerly torezolid, trade name Sivextro), is an oxazolidinone-class antibiotic. Tedizolid phosphate is a phosphate ester prodrug of the active compound tedizolid. It was developed by Cubist Pharmaceuticals, following acquisition of Trius Therapeutics (originator: Dong-A Pharmaceuticals), and is marketed for the treatment of acute bacterial skin and skin structure infections (also known as complicated skin and skin-structure infections (cSSSIs)). The most common side effects include nausea (feeling sick), headache, diarrhoea and vomiting. These side effects were generally of mild or moderate severity. Tedizolid was approved for medical use in the United States in June 2014, and for medical use in the European Union in March 2015. Medical uses Tedizolid was approved by the U.S Food and Drug Administration (FDA) on June 20, 2014, with the indication for the treatment of acute bacterial Skin and skin structure infections (ABSSSI) caused by certain susceptible bacteria ...

Cycloserine
Cycloserine, sold under the brand name Seromycin, is a GABA transaminase inhibitor and an antibiotic, used to treat tuberculosis. Specifically it is used, along with other antituberculosis medications, for active drug resistant tuberculosis. It is given by mouth. Common side effects include allergic reactions, seizures, sleepiness, unsteadiness, and numbness. It is not recommended in people who have kidney failure, epilepsy, depression, or are alcoholics. It is unclear if use during pregnancy is safe for the baby. Cycloserine is similar in structure to the amino acid D-alanine and works by interfering with the formation of the bacteria's cell wall. Cycloserine was discovered in 1954 from a type of '' Streptomyces''. It is on the World Health Organization's List of Essential Medicines. Medical uses Tuberculosis For the treatment of tuberculosis, cycloserine is classified as a second-line drug, i.e. its use is only considered if one or more first-line drugs cannot be used. ...

Rivaroxaban
Rivaroxaban, sold under the brand name Xarelto among others, is an anticoagulant medication (blood thinner) used to treat and prevent blood clots. Specifically it is used to treat deep vein thrombosis and pulmonary emboli and prevent blood clots in atrial fibrillation and following hip or knee surgery. It is taken by mouth. Common side effects include bleeding. Other serious side effects may include spinal hematoma and anaphylaxis. It is unclear if use in pregnancy and breastfeeding is safe. Compared to warfarin it has fewer interactions with other medications. It works by blocking the activity of the clotting protein factor Xa.
