enol

 [e´nol]
an organic compound in which one carbon of a double-bonded pair is also attached to a hydroxyl group, thus a tautomer of the ketone form. The term is also used as a prefix or infix, often italicized.

e·nol

(ē'nol),
A compound possessing a hydroxyl group (alcohol) attached to a doubly bonded (ethylenic) carbon atom (-CH=CH(OH)-); properly italicized when attached as a prefix or infix to an otherwise complete name, for example, enolpyruvate, phosphoenolpyruvate; usually in equilibrium with its keto tautomer.
[-ene + -ol]

enol

(e´nol) an organic compound in which one carbon of a double-bonded pair is also attached to a hydroxyl group, thus a tautomer of the ketone form; also used as a prefix or infix, often italicized.

enol

[ē′nol]
an organic compound with an alcohol or hydroxyl group directly attached (bonded) to a double bond. By transfer of the hydrogen atom from oxygen to carbon, the enol form becomes the (usually more stable) keto form. Such compounds usually exist as enol-keto tautomers.

e·nol

(ē'nol)
A compound possessing a hydroxyl group (alcohol) attached to a doubly bonded (ethylenic) carbon atom (-CH=CH(OH)-).

enol

one of two tautomeric forms of a substance, the other being the keto form; the enol is formed from the keto by migration of hydrogen from the adjacent carbon atom to the carbonyl group.

As is evident from the above data, the Schiff base ligands(1a-3a) behave as dibasic tridentate ligands and co-ordinate through phenolic oxygen, azomethine nitrogen and enolic oxygen atoms.
4) Meloxicam is a member of the enolic class of NSAIDs that, at low doses, have been reported to inhibit preferentially the cycloxygenase-2 (COX-2) prostaglandin metabolic pathway.
Meloxicam is a NSAID in the group of the enolic acids found to preferentially inhibit cyclooxygenase-2 (COX-2) rather than cyclo-oxygenase-1 (COX-1), the latter being responsible for physiologic processes such as renal and gastric mucosal protection.
Aspalathin and nothofagin (>95% purity; HPLC-DAD; LC-MS) were obtained from the PROMEC Unit of the South African Medical Research Council (Parow, South Africa), while enolic phenylpyruvic acid-2-0-glucoside (PPAG; >95% purity; HPLC-DAD; LC-MS) was obtained from the natural product library of the Post-Harvest and Wine Technology Division of the Agricultural Research Council of South Africa (ARC In fruitec-Nietvoorbij, Stellenbosch, South Africa).
