Anti-Candida Activity of 4-Morpholino-5-Nitro- and 4,5-Dinitro-Imidazole Derivatives

The activities of some 4-morpholino-5-nitro- and 4,5-dinitro-imidazole derivatives with respect to several Candida species were evaluated. It is established that 4,5-dinitroimidazole derivatives constitute an important group of compounds possessing antifungal activity against Candida species. Some analogs showed moderate antifungal ability in vitro, especially in relation well-known antifungals such as flucytosine (5FC). The best results of antifungal action were obtained for 1-(3-bromo-2-hydroxypropyl)-2-methyl-4,5-dinitroimidazole (3c), 1-(3-bromo-2-oxopropyl)-2-methyl-4,5-dinitroimidazole (4c) and 2-methyl-1-phenacyl-4,5-dinitroimidazole (2b). The latter compound proved to be effective against Candida sake S-1 (in contrast to inactive 5FC).

Thermal, spectral and biological investigation of new nickel complexes with imidazole derivatives

Four new Ni(II) complexes with acrylate and imidazole (Him) or imidazole derivatives [2-methylimidazole(2-MeIm)/5-methylimidazole(5-MeIm)/2-ethylimidazole(2-EtIm)] as ligands were prepared and characterized. All coordination compounds were characterized by elemental analysis, infrared (FTIR) and ultraviolet-visible-near-infrared (UV-Vis-NIR) spectroscopy, mass spectroscopy, magnetic moments measurements and thermal analysis (TG). The resulted complexes were formulated as follows: [Ni(HIm)(2)(acr)(2)] (1), [Ni(2-MeIm)(2)(acr)(2)(H2O)] center dot H2O (2), [Ni(5-MeIm)(2)(acr)(2)]center dot H2O. (3), [Ni(2-EtIm)(2)(acr)(2)(H2O)] center dot H2O (4). On the basis of magnetic moments measurements and on UV-Vis-NIR spectra, for all Ni(II) complexes was proposed an octahedral stereochemistry. Acrylate ions act as bidentate in complexes (1) and (3); meanwhile, in (2) and (4) they behave as bidentate and unidentate. Antimicrobial activity of complexes was investigated on ATCC reference and clinical microbial strains. The MIC (minimum inhibitory concentration) values revealed moderate antimicrobial activity of complex (1) against Enterococcus faecium and of complex (2) against Pseudomonas aeruginosa and Bacillus subtilis.

Achiral and alpha-Amino Acid Derived Dicationic Imidazoliophanes

Achiral and chiral imidazoliophanes were prepared by N-alkylation of chiral imidazole derivatives featuring an alpha-amino acid motif and subsequent double quarternization of the imidazole N3-position of the corresponding precyclophanes. Eight new optically pure imidazoliophanes were synthesized in good yields, whereas the molecular structure of one achiral analogue was confirmed by X-ray analysis.

An effective process for the green and rapid synthesis of biologically active polysubstituted pyrroles and 1,2,4,5-tetrasubstituted imidazoles derivatives using Cu@imine/Fe3O4 MNPs catalyst under solvent-free conditions is explained. This catalyst showed high reactivity for the synthesis of a set of different derivatives of polysubstituted pyrroles and 1,2,4,5-tetrasubstituted imidazole derivatives under appropriate reaction conditions and short times. Moreover, the catalyst was also recycled and reused for six runs with no considerable reduction in reactivity and yields. Compared to the reported procedures, this method consistently demonstrates the advantages of low catalyst loading, short reaction times, easy separation and purification of the products, high yields, and high recoverability and recoverability of the catalyst.

Design, synthesis and aromatase inhibitory activities of novel indole-imidazole derivatives

A series of novel indole-imidazole derivatives have been prepared and evaluated in vitro on the aromatase inhibitory activities. The results suggested that proton or a small electron-withdrawing group at para-position of the phenyl ring would enhance the inhibitory activities and any bulky group should be avoided in order to keep a relative small volume for this kind of molecules.

Fast and accurate predictions of heat of formation by G4MP2-SFM parameterization scheme: An application to imidazole derivatives

We proposed a new parameterization scheme, G4MP2-SFM, for the prediction of heat of formation by combining SFM (Systematic Fragmentation Method) and high accuracy G4MP2 theories. In an application to imidazole derivatives, we found that the overall MAD and RMSD of the particular G4MP2-SFM(opt) are 1.9 and 2.2 kcal/mol, respectively, demonstrating its high prediction accuracy. In addition, our parameterization scheme replaces the ab initio computations with a set of simple arithmetic, allowing fast predictions. Our new computational scheme can be of practical use in high throughput search for new high energy materials. (C) 2014 Elsevier B. V. All rights reserved.

EVALUATION OF THE MUTAGENIC AND GENOTOXIC ACTIVITIES OF 48 NITROIMIDAZOLES AND RELATED IMIDAZOLE DERIVATIVES BY THE AMES TEST AND THE SOS CHROMOTEST

The mutagenic and genotoxic activities of 48 nitroimidazoles and related imidazole derivatives have been evaluated by using modified versions of the Ames test and the SOS Chromotest. Salmonella typhimurium tester strain TA 100 was used with and without metabolic activation in the Ames test and Escherichia coli tester Strain PQ 37 was used with and without metabolic activation in the SOS Chromotest. Including metronidazole and dimetridazole, 45 derivatives were mutagenic and genotoxic. The mutagenic potencies (MP) ranged from 0.127 to 53,717 revertants/nmol while the SOS induction powers (SOSIP) ranged from 0.00131 to 107 IF/nmol. The overall correlation between MP and SOSIP was r = 0.845 (n = 84) as calculated by linear regression analysis. A higher correlation was observed between MP and SOSIP without the S9 mix than with it. Among the imidazole derivatives, the 5-nitroimidazoles with a lactam ring at the 2-position showed the highest MP and SOSIP. The presence of a nitro group at the 5-position was critical for the mutagenicity and the genotoxicity of the derivatives. Substituents at the 1- and 2-positions were also found to modulate these activities.
