A series of analogs of N-benzylimidazole was prepared and tested for hypolipidemic activity. Both plasma cholesterol and triglyceride-lowering activity were found in several members of the series. The most active compounds were N-3-methoxy-, N-4-methoxy-, and N-4-methylbenzylimidazole. Structure-activity relationships are discussed.

American Pharmacy, 1991
Vaginal candidiasis is a common infection in women for which several effective therapeutic agents are currently available. Clotrimazole and miconazole were introduced in 1975, and both recently became available over the counter. These imidazole agents have largely replaced nystatin as primary therapy because of greater antifungal activity and shorter ...

Imidazole: Fungitoxic Derivatives
Science, 1967Study of several new types of fungitoxic derivatives of imidazole reveals that imidazoles substituted on the imine nitrogen atom are likely to be active if the substituent is electron-attracting, and if the atom connecting it to the imidazolyl moiety has tetrahedral geometry.

Synthesis of difluoromethylthio imidazole from methylthio imidazole
Journal of Fluorine Chemistry, 1996Abstract Demethylation of methylthio imidazole 1 via a Pummerer rearrangement onto the corresponding sulfoxide 2 afforded imidazole thiol 4 which was then difluoromethylated with the sodium chlorodifluoroacetate/NaI system in 71% overall yield.

Imidazole–imidazole stacking in some inorganic complexes
Inorganica Chimica Acta, 2009Abstract Reaction of CuCl2 · 2H2O with the 1:1 condensate (L) of 2-(2-aminoethyl)pyridine and 1-methyl-2-imidazolecarboxaldehyde in methanol yields monomeric CuLCl2.H2O (1). Recrystallisation of 1 from aqueous methanol medium containing excess of PF 6 − affords the 1D coordination polymer [CuLCl]n(PF6)n (2).

Imidazole anticonvulsants: structure-activity relationships of [(biphenylyloxy)alkyl]imidazoles
Journal of Medicinal Chemistry, 1987The [(biphenylyloxy)alkyl]imidazoles were found to be potent anticonvulsants. The most potent compound of the series, 1-[2- ([1,1'-biphenyl]-2-yloxy)ethyl]-1H-imidazole (4), had an ED50 of 15.5 mg/kg against maximal-electroshock-induced seizures in mice after oral administration; the horizontal screen ED50 was 320 mg/kg, revealing that the compound has

Prebiotic synthesis of imidazole-4-acetaldehyde, imidazole-4-glycol and imidazole-4-ethanol
Origins of life and evolution of the biosphere, 1986A wide var iety of chemical processes have been used for the synthesis of amino acids from prebiot ic molecular precursors under plausible pr imi t ive Earth conditions (M i l l e r , 1982). The prebiot ic formation of a l l protein-type amino acids has been demonstrated except for three amino acids: h is t id ine , lys ine, and arginine (Weber and Mi ...

Abstract Myoglobin is photooxidized when exposed to visible light in the presence of a sensitizer. In 8 M urea medium this photooxidation is followed by photodynamic interpeptide crosslinking. A partial inhibition of crosslinking is caused by lysine, mercaptoethanol and hydroxylamine, and by amidination of NH2 groups in the protein molecule. Complete

AbstractBei der Umsetzung von α‐(3,4‐Dihydroisochinolinium)‐ketonen mit Hydroxylamin bei pH 4–5 entstehen keine Oxime, sondern kondensierte Imidazolderivate. Durch Modellversuche wird ein Reaktionsverlauf über ein N‐substituiertes Hydroxylamin ausgeschlossen.
