Spectroscopic determination of acid dissociation constants of some imidazole derivatives

The acid dissociation constants, pK(a), of eight biologically active imidazole derivatives were determined using a spectroscopic technique. Using the obtained acid dissociation constants, attempts were made to elucidate the structures and protonation mechanisms of these derivatives. Four of eight molecules were found to behave as Hammett base for the first protonation.

Design of new ionic liquids by neutralization of imidazole derivatives with imide-type acids

A series of new ionic liquids were prepared by neutralizing five different imidazole derivatives with two imide-type acids such as bis(trifluoromethanesulfonyl)imide and bis(perfluoroethylsulfonyl)imide, and their ionic conductivity and thermal properties were investigated. All the imidazolium salts synthesized are liquid at room temperature. The ionic liquid of the methylimidazolium bis(trifluoromethanesulfonyl)imide system has the best ionic conductivity, 7.23 x 10(-3) S cm(-1) at 25 degreesC, of the series of five imidazolium salts.

Practical and Efficient Synthesis of 2-Thio-imidazole Derivative-ZY12201: A Potent TGR5 Agonist

Early scalable process development for the synthesis of ZY12201, a novel TGR5 receptor agonist, as a potential clinical candidate is described. A practical, efficient, and scalable synthetic route provided ZY12201 in seven steps and 32% overall yield. The key step involves an inexpensive acetic acid-mediated cyclization of thiourea 6 for the construction of 2-thio-imidazole derivative 7. The developed process demonstrated cost-effective, high-yielding, kilogram-scalable, and environmentally friendly synthesis of ZY12201. This high-yielding route enabled us to rapidly synthesize large quantities of ZY12201 in 99% purity to support in vivo and toxicity studies.

A four-component synthesis of highly substituted imidazole derivatives

Addition of lithiated methoxyallene 1 to imines 2 provided allenyl amines 3, which upon reaction with iodine and nitriles furnished dihydroimidazole derivatives 5. Treatment of these intermediates with strong acids such as trifluoromethane sulfonic acid afforded tetrasubstituted imidazole derivatives 6 in good overall yields. Subsequent base-promoted conversion of 1-iodovinyl-substituted compounds 6 into alkynyl-substituted imidazole derivatives 7 proceeded smoothly. Products 6 and 7 are versatile intermediates for further transformations such as palladium-catalyzed coupling reactions.

An insight into the synthesis of cationic porphyrin-imidazole derivatives and their photodynamic inactivation efficiency against Escherichia coli

New porphyrin-imidazole derivatives were synthesised by Radziszewski reaction between 2-formyl-5,10,15,20-tetraphenylporphyrin 1 and several (hetem)aromatic 1,2-diones, which after cationization afforded promising monocationic photosensitizers 3a-d. Singlet oxygen studies have demonstrated that all the cationic porphyrin-imidazole conjugates 3a-d were capable to produce cytotoxic species. These photosensitizers were able to photoinactivate Eschericha coli and their inactivation profile was improved in the presence of KI.

Optoelectronic features of Y-shaped push-pull molecules based on imidazole

The paper involves organic light-emitting diodes fabricated with application of Y-shaped push-pull imidazole derivatives (chromophores) blended with poly(N-vinylcarbazole) as an organic active materials. The absorbance, photoluminescence and electroluminescence spectra of chromophores as well as electroluminescence-voltage, current-voltage and electroluminescence-voltage of the manufactured devices are presented. All investigated imidazole derivatives dissolved in tetrahydrofuran exhibited strong luminescence. The investigated organic light-emitting diodes exhibit red-shift in the main spectral maxima from 520 to 598 nm for photoluminescence and from 535 to 590 nm for electroluminescence depending on the type of imidazole derivative used. The electroluminescence spectra also proved to be very stable over the luminance range from 700 to 1600 cd/m(2), which is the luminance used for typical lighting applications.

Luminescent study on the binding interaction of bioactive imidazole with bovine serum albumin A static quenching mechanism

Novel bioactive imidazole derivatives were synthesized and characterized by NMR spectra, mass and CHN analysis. The interaction between the imidazole derivative and bovine serum albumin (BSA) was investigated by fluorescence and UV-vis absorption spectroscopy. The fluorescence quenching of BSA by the imidazole derivatives may be due to the formation of imidazole-BSA complex. The fluorescence quenching mechanism of BSA by irnidazole was analyzed and the binding constant has been calculated. The binding distance between imidazole and BSA was obtained based on Forester’s non-radiation energy transfer (FRET). The effect of some common ions on the binding constant between imidazole and BSA was also examined. (C) 2011 Elsevier B.V. All rights reserved.
