L-Asparagine is a non-essential amino acid involved in the metabolic control of cell functions in nerve and brain tissue. It is biosynthesized from aspartic acid and ammonia by asparagine synthetase.

Non steroidal anti inflammatory drugs, usually abbreviated to NSAIDs or NAIDs, are drugs with analgesic, antipyretic and, in higher doses, anti inflammatory effects – they reduce pain, fever and inflammation. Most NSAIDs act as nonselective inhibitors of the enzyme cyclooxygenase, inhibiting both the cyclooxygenase 1 (COX 1) and cyclooxygenase 2 (COX 2) isoenzymes. Cyclooxygenase catalyzes […]

Melengestrol (INN, BAN) is a steroidal progestin and antineoplastic agent which was never marketed. An acylated derivative, melengestrol acetate, is used as a growth promoter in animals. While melengestrol is sometimes used as a synonym for melengestrol acetate, what is usually being referred to is actually melengestrol acetate and not melengestrol.

Megestrol (INN, BAN) is a steroidal progestin which was never marketed. Its acylated derivative megestrol acetate is also a progestogen, which, in contrast to megestrol itself, has been extensively used as a pharmaceutical drug.

Nitroglutathione is a product of the nitric oxide generating reaction between peroxynitrite and glutathione.

The organic compound citrulline is an α-amino acid. Its name is derived from citrullus, the Latin word for watermelon, from which it was first isolated in 1914 by Koga and Odake. It was finally identified by Wada in 1930. It has the idealized formula H2NC(O)NH(CH2)3CH(NH2)CO2H. It is a key intermediate in the urea cycle, the […]
