Fenamic Acid
Fenamic acid is an organic compound, which, especially in its ester form, is called fenamate. serves as a parent structure for several nonsteroidal anti-inflammatory drugs (NSAIDs), including mefenamic acid, tolfenamic acid, flufenamic acid, and meclofenamic acid. These drugs are commonly referred to as "anthranilic acid derivatives" or "fenamates" because fenamic acid is a derivative of anthranilic acid Anthranilic acid is an aromatic acid with the formula C6H4(NH2)(CO2H) and has a sweetish taste. The molecule consists of a benzene ring, ''ortho''-substituted with a carboxylic acid and an amine. As a result of containing both acidic and basic f ....Sriram D, Yogeeswari PMedicinal Chemistry, 2nd Edition Pearson Education India, 2010. Fenamic acid can be synthesized from 2-chlorobenzoic acid and can be converted into acridone. References {{Prostanoidergics Anthranilic acids Nonsteroidal anti-inflammatory drugs ...

Mefenamic Acid
Mefenamic acid is a member of the Nonsteroidal anti-inflammatory drug#Anthranilic acid derivatives .28fenamates.29, anthranilic acid derivatives (or fenamate) class of nonsteroidal anti-inflammatory drugs (NSAIDs), and is used to treat mild to moderate pain. Its name derives from its systematic name, dimethylphenylaminobenzoic acid. It was discovered and brought to market by Parke-Davis as Ponstel in the 1960s. It became generic in the 1980s and is available worldwide under many brand names such as ''Meftal''. Medical uses Mefenamic acid is used to treat pain and inflammation in rheumatoid arthritis and osteoarthritis, postoperative pain, acute pain including muscle pain, muscle and back pain, toothache and dysmenorrhoea, menstrual pain, as well as being prescribed for menorrhagia. In a 10-year study, mefenamic acid and other oral medicines (tranexamic acid) were as effective as the Hormonal intrauterine device, levonorgestrel intrauterine coil; the same proportion of women had ...

Organic Compound
Some chemical authorities define an organic compound as a chemical compound that contains a carbon–hydrogen or carbon–carbon bond; others consider an organic compound to be any chemical compound that contains carbon. For example, carbon-containing compounds such as alkanes (e.g. methane ) and its derivatives are universally considered organic, but many others are sometimes considered inorganic, such as certain compounds of carbon with nitrogen and oxygen (e.g. cyanide ion , hydrogen cyanide , chloroformic acid , carbon dioxide , and carbonate ion ). Due to carbon's ability to catenate (form chains with other carbon atoms), millions of organic compounds are known. The study of the properties, reactions, and syntheses of organic compounds comprise the discipline known as organic chemistry. For historical reasons, a few classes of carbon-containing compounds (e.g., carbonate salts and cyanide salts), along with a few other exceptions (e.g., carbon dioxide, and even ...

Nonsteroidal Anti-inflammatory Drug
Non-steroidal anti-inflammatory drugs (NSAID) are members of a Indication (medicine), therapeutic drug class which Analgesic, reduces pain, Anti-inflammatory, decreases inflammation, Antipyretic, decreases fever, and Antithrombotic, prevents blood clots. Side effects depend on the specific drug, its dose and duration of use, but largely include an increased risk of Stomach ulcers, gastrointestinal ulcers and bleeds, heart attack, and kidney disease. The term ''non-steroidal'', common from around 1960, distinguishes these drugs from corticosteroids, another class of anti-inflammatory drugs, which during the 1950s had acquired a bad reputation due to overuse and side-effect problems after their introduction in 1948. NSAIDs work by inhibiting the activity of cyclooxygenase enzymes (the COX-1 and COX-2 isozyme, isoenzymes). In cells, these enzymes are involved in the synthesis of key biological mediators, namely prostaglandins, which are involved in inflammation, and thromboxanes, ...

Tolfenamic Acid
Tolfenamic acid is a member of the anthranilic acid derivatives (or fenamate) class of NSAID drugs. Like other members of the class, it is a COX inhibitor and prevents formation of prostaglandins. It is used in the UK as a treatment for migraine. It is generally not available in the US.NIH LiverTox DatabasMefenamic AcidLast updated June 23, 2015. Page accessed July 3, 2015. Quote: "(fenamates generally not available in the United States, such as tolfenamic acid and flufenamic acid)" It is available in some Asian, Latin American and European countries as a generic drug for humans and for animals. Medical uses Tolfenamic acid finds utility in the prevention and treatment of conditions associated with pain and inflammation. However, despite its efficacy when administered intramuscularly, subcutaneously, or orally, TFA-based drugs have not yet gained approval in the United States and some other countries due to the significant number of reported side effects.

Meclofenamic Acid
Meclofenamic acid (used as meclofenamate sodium, brand name Meclomen) is a drug used for joint, muscular pain, arthritis and dysmenorrhea. It is a member of the anthranilic acid derivatives (or fenamate) class of nonsteroidal anti-inflammatory drugs (NSAIDs) and was approved by the US FDA in 1980. Like other members of the class, it is a cyclooxygenase (COX) inhibitor, preventing the formation of prostaglandins. Scientists led by Claude Winder from Parke-Davis invented meclofenamate sodium in 1964, along with fellow members of the class, mefenamic acid in 1961 and flufenamic acid in 1963. Patents on the drug expired in 1985 and several generics were introduced in the US, but as of July 2015 only Mylan still sold it. It is not widely used in humans as it has a high rate (30-60%) rate of gastrointestinal side effects. Adverse effects In October 2020, the U.S. Food and Drug Administration (FDA) required the drug label to be updated for all nonsteroidal anti-inflammatory medi ...

Anthranilic Acid
Anthranilic acid is an aromatic acid with the formula C6H4(NH2)(CO2H) and has a sweetish taste. The molecule consists of a benzene ring, ''ortho''-substituted with a carboxylic acid and an amine. As a result of containing both acidic and basic functional groups, the compound is amphoteric. Anthranilic acid is a white solid when pure, although commercial samples may appear yellow. The anion 6H4(NH2)(CO2)sup>−, obtained by the deprotonation of anthranilic acid, is called anthranilate. Anthranilic acid was once thought to be a vitamin and was referred to as vitamin L1 in that context, but it is now known to be non-essential in human nutrition. Structure Although not usually referred to as such, it is an amino acid. Solid anthranilic acid typically consists of both the amino-carboxylic acid and the zwitterionic ammonium carboxylate forms, and has a monoclinic crystal structure with space group P21. It is triboluminescent. Above , it converts to an orthorhombic form with spa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acridone
Acridone is an organic compound based on the acridine skeleton, with a carbonyl group at the ''9'' position. Synthesis and structure The molecule is planar. Optical spectra reveal that the keto tautomer predominates in the gas-phase and in ethanol solution. Acridone can be synthesized by heating fenamic acid. History One of the first who were able to prove the compound's existence was Karl Drechsler, Student of G. Goldschmiedt, at the k.u.k. Universität Wien (Vienna, Austria) in 1914. Derivatives Acridone constitutes the scaffold of some synthetic compounds with diverse pharmacological activities. 3-Chloro-6-(2-diethylamino-ethoxy)-10-(2-diethylamino-ethyl)-acridone has shown promise as an antimalarial drug Antimalarial medications or simply antimalarials are a type of antiparasitic chemical agent, often naturally derived, that can be used to treat or to prevent malaria, in the latter case, most often aiming at two susceptible target groups, young c ....
