The activity of egg lecithin in preventing the antifungal action of the two imidazole antimycotics, clotrimazole and miconazole, was confirmed. However, addition of this phospholipid could not relieve an existing imidazole inhibition. Compared with egg lecithin, reduced egg lecithin showed no such protective effect. The addition of egg lecithin to an aqueous suspension of the imidazole drugs ch...

The title compound, [Fe(C44H28N4)(C4H6N2)2]·2C4H6N2, is a six-coordinate Fe(II)-porphyrinate complex with the metal located on a center of inversion and coordinated by two axial 1-methyl-imidazole ligands; the complex crystallizes as a 1-methyl-imidazole disolvate. The 1-methyl-imidazole group bonded to the Fe(II) atom [occupancy ratio 0.789 (4):0.211 (4)] and the unbound 1-methyl-imidazole mol...

The title complex, [Fe(C(19)H(27)N(10))](ClO(4))(3)·2H(2)O, is a new polymorph of an iron(II) Schiff base complex of tris-(2-amino-ethyl)methyl-ammonium with imidazole-2-carboxaldehyde. The octa-hedral Fe(II) atom is bound to three facial imidazole N atoms with average Fe-N(imidazole) and Fe-N(imine) bond distances of 1.963 (5) and 1.951 (5) Å, respectively. The central N atom of the tripodal l...

Solution equilibrium studies on Fe(III) complexes formed with imidazole-4-carbohydroxamic acid (Im-4-Cha), N-Me-imidazole-4-carbohydroxamic acid (N-Me-Im-4-Cha), imidazole-4-acetohydroxamic acid (Im-4-Aha), and histidinehydroxamic acid (Hisha) have been performed by using pH-potentiometry, UV-visible spectrophotometry, EPR, ESI-MS, and H1-NMR methods. All of the obtained results demonstrate tha...

Protein expression after delivery of plasmid DNA to the cell nucleus depends on the processes of transcription and translation. Cytotoxic gene-delivery systems may compromise these processes and limit protein expression. This situation is perhaps most prevalent in current nonviral polycationic gene-delivery systems in which the polycationic nature of the delivery system can lead to cytotoxicity...

Bioactive imidazole derivative absorbs in the UV region at 305 nm. The interaction of imidazole derivative with nanoparticulate WO3, Fe2O3, Fe3O4, CuO, ZrO2 and Al2O3 has been studied by UV-visible absorption, FT-IR and fluorescence spectroscopies. The imidazole derivative adsorbs strongly on the surfaces of nanosemiconductor, the apparent binding constants for the association between nanomater...

In the asymmetric unit of the title compound, C13H13N3O3, the 2-(2-methoxphen-yl)ethenyl unit is connected to the methyl-nitro-imidazole 1-methyl-4-nitro-1H-imidazole moiety. The mol-ecule is quasi-planar and the planes of the two rings form a dihedral angle of 0.92 (11)°. The crystal packing can be described as layers parallel to the (011) plane, stabilized by inter-molecular C-H⋯O hydrogen bo...

Reduction currents for H2O2 at a heme peptide (HP)-modified electrodes are suppressed by inhibitors, such as imidazole derivatives. Although this inhibition effect allows determinations of the total inhibition ability of imidazole derivatives, it has no selectivity. In this study the selectivity control of HP-modified electrodes for imidazole derivatives was performed utilizing the thermorespon...

INTRODUCTION In recent years, studies of the reaction rates of small molecules in the presence of synthetic polymers containing catalytically active functions have contributed significantly to the understanding of the mechanism of enzyme behaviour1. Of particular interest in the field of polymeric catalysis have been the studies of the solvolyses of esters catalyzed by polymers containing pende...
