One, and only one, lone pair of electrons from each heteroatom in the ring is part of the aromatic bonding in an azole. Names of azoles maintain the prefix upon reduction (e.g., pyrazoline, pyrazolidine). The numbering of ring atoms in azoles starts with the heteroatom that is not part of a double bond, and then proceeds towards the other ...
3-(Difluoromethyl)-1-methyl-1H-pyrazole-4-carboxylic acid is used in the manufacture of six commercial fungicides which are inhibitors of succinate dehydrogenase. [ 20 ] [ 21 ] Pyrazole is an inhibitor of the alcohol dehydrogenase enzyme, and, as such, is used as an adjuvant with ethanol, to induce alcohol dependency in experimental laboratory ...
The 1,2,3-isomer is unstable and ring-opens to form the diazo ketone tautomer; [2] however, it does exist within the unusual sydnone motif. [ 1 ] In 2018, a compound called bis(1,2,4-oxadiazole)bis(methylene) dinitrate which might have 1.5 times the power of TNT was developed at the United States Army Research Laboratory (ARL) working with the ...
Drug nomenclature is the systematic naming of drugs, especially pharmaceutical drugs.In the majority of circumstances, drugs have 3 types of names: chemical names, the most important of which is the IUPAC name; generic or nonproprietary names, the most important of which are international nonproprietary names (INNs); and trade names, which are brand names.

Development of resistance to one azole in this way will confer resistance to all drugs in the class. Another resistance mechanism employed by both C. albicans and C. glabrata is increasing the rate of efflux of the azole drug from the cell, by both ATP-binding cassette and major facilitator superfamily
Oxazole is the parent compound for a vast class of heterocyclic aromatic organic compounds.These are azoles with an oxygen and a nitrogen separated by one carbon. [4] Oxazoles are aromatic compounds but less so than the thiazoles.
This multi-page article lists pharmaceutical drugs alphabetically by name. Many drugs have more than one name and, therefore, the same drug may be listed more than once. Brand names and generic names are differentiated by capitalizing brand names. See also the list of the top 100 bestselling branded drugs, ranked by sales.
Isoxazoles also form the basis for a number of drugs, [9] including the COX-2 inhibitor valdecoxib and a neurotransmitter agonist AMPA. A derivative, furoxan, is a nitric oxide donor. An isoxazolyl group is found in many beta-lactamase-resistant antibiotics, such as cloxacillin, dicloxacillin and flucloxacillin. Leflunomide is an isoxazole ...
