In this research, ZnO nanoparticles modified with imidazole in O-xylene solution and characterized with Fourier transform infrared FTIR spectroscopy. Then, polyaniline-ZnO unmodified and imidazole modified nanocomposites were synthesized via in-situ emulsion polymerization method. The synthesized nanocomposites were characterized by FTIR and scanning electron microscopy SEM. The anti-corrosion ...

Skin cancer has been reported as a contemporary malignant cancer. Here, anti-cancer effects of sea cucumber extract (SCE) from Holothuria arenicola have been examined on melanoma cells and compared with imidazole carboxamide (Dacarbazine) as a chemotherapy medication against melanoma and Hodgkin's lymphoma. MTT assay and morphological analysis were performed to evaluate cytotoxic effects of H. ...

Abstract In this study, the molecular dynamics simulation of imidazole-modified polyacrylamide (VPAM) and (PAM) system showed that VPAM containing had better cohesion-bonding effect than PAM without imidazole. Based on imidazole-containing system, cohesion properties functional monomers mechanism in process were analyzed at high temperature salt, structure-activity relationships between chemica...

Mono- and binuclear arene–ruthenium(II) complexes with imidazole-containing ligands were prepared by the reaction of (L1 = bis(imidazole-1-yl)methane; ImH 1H-Imidazole; BImH 1H-Benzimidazole) [(p-cym)Ru(µ-Cl)2]2 dimers. When bis(imidazole-1-yl)methane reacted in methanol, a complex type [Ru2(L1)2(p-cym)2Cl2]Cl2 (2) cyclic structure was synthesized, whereas using acetonitrile as solvent under sa...

a series of 1,4-dihydropyridine calcium channel blockers bearing 1-(4-x -benzyl)-5-imidazolyl substituent at 4 position (5a-e) (x=h, f) were synthesized and tested for antihypertensive activity in desoxycorticosterone acetate (doca)-induced hypertension in rats. amlodipine was used as the standard dihydropyridine. all compounds tested showed lower antihypertensive activity than that of amlodipi...

Imidazole is a planar, five membered heteroaromatic molecule with pyrrole type and pyridine type annular nitrogens. Several approaches are available of imidazoles from alpha halo ketones, aminonitrile, aldehyde ect. Reactivity of imidazole and benzimidazole is referred from sets of  resonance structure in which the dipolar contributors have finite importance. Imidazoles among the principal grou...

Hydrolysis of RNA in imidazole buffer and by spermine-imidazole conjugates has been investigated. The RNA models were yeast tRNA(Asp) and a transcript derived from the 3'-terminal sequence of tobacco mosaic virus RNA representing a minihelix capable of being enzymatically aminoacylated with histidine. Imidazole buffer and spermine-imidazole conjugates in the presence of free imidazole cleave ph...
