The best-selling drug in the U.S., Acetaminophen, also known as Paracetamol, is a phenol. There are various classification schemes. [ 15 ] : 2 A commonly used scheme is based on the number of carbons and was devised by Jeffrey Harborne and Simmonds in 1964 and published in 1980: [ 15 ] : 2 [ 16 ]
Phenol is also a versatile precursor to a large collection of drugs, most notably aspirin but also many herbicides and pharmaceutical drugs. Phenol is a component in liquid–liquid phenol–chloroform extraction technique used in molecular biology for obtaining nucleic acids from tissues or cell culture samples.
Main article: Flavonoid biosynthesis. Flavonoids are secondary metabolites synthesized mainly by plants. The general structure of flavonoids is a fifteen-carbon skeleton, containing two benzene rings connected by a three-carbon linking chain. [ 1 ] Therefore, they are depicted as C6-C3-C6 compounds.
Flavones. Molecular structure of the flavone backbone with numbers. Flavones (from Latin flavus "yellow") are a class of flavonoids based on the backbone of 2-phenylchromen-4-one (2-phenyl-1- benzopyran -4-one) (as shown in the first image of this article). [1][2] Flavones are common in foods, mainly from spices, and some yellow or orange ...
Phenothiazine, abbreviated PTZ, is an organic compound that has the formula S (C 6 H 4) 2 NH and is related to the thiazine -class of heterocyclic compounds. Derivatives of phenothiazine are highly bioactive and have widespread use and rich history.
Anthraquinones (also known as anthraquinonoids) are a class of naturally occurring phenolic compounds based on the 9,10-anthraquinone skeleton. They are widely used industrially and occur naturally. The name "anthraquinone" was first used by German chemists Carl Graebe and Carl Theodore Liebermann in a 1868 publication describing the chemical ...
For example, acorns of Quercus robur and Quercus petraea in Poland were found to contain 2.4–5.2% and 2.6–4.8% tannins as a proportion of dry matter, [50] but the tannins can be removed by leaching in water so that the acorns become edible. [51] Other nuts – such as hazelnuts, walnuts, pecans, and almonds – contain lower amounts. Tannin ...
Sulfonamide is a functional group (a part of a molecule) that is the basis of several groups of drugs, which are called sulphonamides, sulfa drugs or sulpha drugs. The original antibacterial sulfonamides are synthetic (nonantibiotic) antimicrobial agents that contain the sulfonamide group. Some sulfonamides are also devoid of antibacterial ...
