Structure of imidazole methemoglobin

Journal of Molecular Biology, 1981
Abstract Crystals of horse methemoglobin shatter when soaked in crystallization buffer containing high concentrations of imidazole. By using less than saturating concentrations of imidazole, a stable imidazole derivative of crystalline methemoglobin was prepared and analyzed by X-ray difference Fourier techniques.

Zeolite A imidazolate frameworks

Nature Materials, 2007
Faujasite (FAU) and zeolite A (LTA) are technologically important porous zeolites (aluminosilicates) because of their extensive use in petroleum cracking and water softening. Introducing organic units and transition metals into the backbone of these types of zeolite allows us to expand their pore structures, enhance their functionality and access new ...

Prebiotic synthesis of imidazole-4-acetaldehyde, imidazole-4-glycol and imidazole-4-ethanol

Origins of life and evolution of the biosphere, 1986
A 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 ...

Imidazole anticonvulsants: structure-activity relationships of [(biphenylyloxy)alkyl]imidazoles

Journal of Medicinal Chemistry, 1987
The [(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

Regioselective formation of imidazol-2-yllithium, imidazol-4-yllithium, and imidazol-5-yllithium species

The Journal of Organic Chemistry, 1991
We wished to establish definitively the extent to which imidazol-5-yllithium and imidazol-4-yllithium species could be generated and quenched with electrophilic reagents in the presence of an unsubstituted C2 carbon atom ...

On the photochemical phosphorylation of imidazole

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1972
Abstract It has not proved possible to repeat the reported anaerobic photophosphorylation of imidazole to produce imidazole 1-phosphate. The involvement of an analogous reaction in mitochondrial oxidative phosphorylation is therefore further in doubt.

New complexes of copper cinnamates and imidazole or substituted imidazole

Thermochimica Acta, 1993
Abstract We have prepared five new organo-metallic complexes of imidazoles and a dicarboxylate, copper cinnamate, which may be considered as extremely simple models of the active centres in most biocatalysts. The thermal behaviour of the complexes was studied. Using ESR and diffuse reflectance spectra, monomeric or dimeric species were detected.
