2-Imidazolone analogues of histamine
Experientia, 1964Die 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, 19861. 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 химияWe 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.

Immunochemical detection of imidazolone in uremia and rheumatoid arthritis
Clinica Chimica Acta, 2000The advanced glycation end-product imidazolone is formed by reaction of arginine with 3-deoxyglucosone (3-DG), a reactive intermediate of the Maillard reaction, whose formation is non-oxidative. Using an antibody specific to this 3-DG-derived AGE, we demonstrated the presence of imidazolone-modified proteins in vivo in the urine and dialysate of ...

Antioxidant properties of 2-imidazolones and 2-imidazolthiones
Biochemical Pharmacology, 1987Uric 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, 2008Sixteen 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.

Synthesis of a Stabilized Version of the Imidazolone DNA Lesion
ChemBioChem, 2008AbstractImidazolone (dIz) is an abundant, highly mutagenic, and rather unstable DNA lesion that can cause dG→dC transversion mutations. dIz is generated in DNA by a variety of oxidative processes such as type I photooxidation. Herein we report the synthesis of a carbocyclic nucleoside analogue of dIz and of DNA containing this stabilized lesion ...
