Formal Olefination and Acylaziridination of Imidazolones

Organic Letters, 2010
The first formal olefination and acylaziridination of imidazolones were obtained by cycloaddition of cyclic nitrones with alkenes and alkynes, respectively.

2-Imidazolone analogues of histamine

Experientia, 1964
Die 2-Imidazolon-Analoge der Histamine und 6-Methylspinaceamin wurden synthesiert. Die neuen Imidazolonstoffe scheinen pharmakologisch unwirksam.

Reaction of imidazolones with acylacetylenes

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1986
1. By interacting benzimidazol-2-one with benzoyl- and thenoylacetylenes in acetonitrile in the presence of triethylamine, the N,N-diadducts are obtained. Under similar conditions 4,5-diphenylimidazol-2-one forms both the N-mono- and N,N-diadducts. 2.

Aryliden-imidazolones as fluorogens of NanoLuc protein

Биоорганическая химия
We report a series of orto-substituted aryliden-imidazolones and their derivatives containing styrene moiety. These compounds can be used like ligands of NanoLuc protein. Together with NanoLuc this fluorogens can be used for genetically encoded labeling in fluorescence microscopy, as demonstrated by staining HEK293 cells.

Antioxidant properties of 2-imidazolones and 2-imidazolthiones

Biochemical Pharmacology, 1987
Uric acid has been postulated to be an important antioxidant and free radical scavenger in humans. Other purines, such as xanthine, that lack an 8-oxo group on the imidazole ring do not show antioxidant properties. For this reason, the antioxidative activities of 2-imidazolones and 2-imidazolthiones were compared to that of uric acid. 2-Imidazolthiones

Newer Indolyl Imidazolones as Anti-Inflammatory Agents

Pharmacology, 2008
Sixteen new 1,2-disubstituted-4-(indol-3’-yl)methylene imidazol-5-ones were synthesized by the condensation of oxazolone with different aryl amines and evaluated as to their anti-inflammatory and antiproteolytic activities. These derivatives showed 2–38% protection against carrageenin-induced paw oedema in albino rats at a dose of 100 mg/kg p.o.
