Left: The structure of pyrimidine with the locants for ring atoms marked. Right : 5-Fluorouracil , a fluoropyrimidine formally named as 5-fluoro-1 H ,3 H -pyrimidine-2,4-dione Fluoropyrimidines are a general class organic compounds in which the substituent (s) around a pyrimidine ring include at least one fluorine atom.
Pyrimidine analogues are antimetabolites which mimic the structure of metabolic pyrimidines. Examples. Nucleobase analogues. Fluorouracil (5FU), ...
Pyrimidine (C 4 H 4 N 2; / p ɪ ˈ r ɪ. m ɪ ˌ d iː n, p aɪ ˈ r ɪ. m ɪ ˌ d iː n /) is an aromatic, heterocyclic, organic compound similar to pyridine (C 5 H 5 N). [3] One of the three diazines (six-membered heterocyclics with two nitrogen atoms in the ring), it has nitrogen atoms at positions 1 and 3 in the ring.
Pyrimidines are organic compounds that contain the pyrimidine base structure. Subcategories. This category has the following 9 subcategories, out of 9 total. A.
Pyrimidine is a heterocyclic amine that contains two nitrogen atoms in an unsaturated six-membered ring. An example of a molecule that contains pyrimidine is thiamine, which is also known as vitamin B1. Thiamine deficiency produces beriberi. Pyrimidine is a component of the nucleobases cytosine, uracil, and thymine.
It is an aromatic heterocycle with a bicyclic structure consisting of two fused six-membered aromatic rings, a benzene ring and a pyrimidine ring. It is a light yellow crystalline solid that is soluble in water. Also known as 1,3-diazanaphthalene, quinazoline received its name from being an aza derivative of quinoline. Though the parent ...
An imidazopyridine is a nitrogen containing heterocycle that is also a class of drugs that contain this same chemical substructure. In general, they are GABA A receptor agonists, however recently proton pump inhibitors, aromatase inhibitors, NSAIDs and other classes of drugs in this class have been developed as well. Despite usually being ...
Most of the drugs from this class marketed to date are intended to induce sleep, and are prescribed for people suffering insomnia, however some newer compounds produce anxiolytic effects with relatively little sedation, and are being developed for use as non-sedating anti-anxiety drugs. They include: Zaleplon - hypnotic (trade name Sonata)
