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.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 Acridone is an organic compound based on the acridine skeleton, with a carbonyl group at the ''9'' position. It is a yellow solid. Synthesis and structure The molecule is planar. Optical spectra reveal that the keto tautomer predominates in the ga ....

Mefenamic Acid
Mefenamic acid is a member of the 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 and back pain, toothache and menstrual pain, as well as being prescribed for menorrhagia. There is evidence that supports the use of mefenamic acid for perimenstrual migraine headache prophylaxis, with treatment starting two days prior to the onset of flow or one day prior to the expected onset of the headache and continuing for the duration of menstruation. Mefenamic acid is recommended to be ...

Organic Compound
In chemistry, organic compounds are generally any chemical compounds that contain carbon-hydrogen or carbon-carbon bonds. 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, hydrogen cyanide), are not classified as organic compounds and are considered inorganic. Other than those just named, little consensus exists among chemists on precisely which carbon-containing compounds are excluded, making any rigorous definition of an organic compound elusive. Although organic compounds make up only a small percentage of Earth's crust, they are of central importance because all known life is based on organic compounds. Living t ...

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

Tolfenamic Acid
Tolfenamic acid (Clotam, Tufnil) is a member of the anthranilic acid derivatives (or fenamate) class of NSAID drugs discovered by scientists at Medica Pharmaceutical Company in Finland. 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.

Flufenamic Acid
Flufenamic acid (FFA) is a member of the anthranilic acid derivatives (or fenamate) class of nonsteroidal anti-inflammatory drugs (NSAIDs). Like other members of the class, it is a cyclooxygenase (COX) inhibitor, preventing the formation of prostaglandins. FFA is known to bind to and reduce the activity of prostaglandin F synthase and activate TRPC6. It is not widely used in humans as it has a high rate (30–60%) of gastrointestinal 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 spac ...

It is a purplish-black crystalline salt, that dissolves in water as K+ and , an intensely pink to purple solution. Potassium permanganate is widely used in the c .... Alternatively it arises by the hydrolysis of α,α,α-trichloro-2-toluene. The chloride is readily replaced by ammonia to 2-aminobenzoic acid. Similarly, the chloride is displaced by diphenylphosphide, leading to 2- ...

Acridone
Acridone is an organic compound based on the acridine skeleton, with a carbonyl group at the ''9'' position. It is a yellow solid. 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 the condensation of aniline and 2-chlorobenzoic acid and subsequently heating of ''N''-phenylanthranilic 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. See also * Quinacridone Quinacridone is an organic compound used as a pigment. Numerous derivatives constitute the quinacridone pigment family, which finds e ...
