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.

N-substituted-2-butyl-5-chloro-3H-imidazole-4-carbaldehyde derivatives as anti-tumor agents against Ehrlich ascites tumor cells in vivo

A new series of N-substituted2-butyl-5-chloro-3H-imidazole-4-carbaldehyde derivatives were synthesized by using the different bioactive heteroaralkyl halides with 2-butyl-4-chloro-1H-imidazole-5-carbaldehyde in presence of powdered potassium carbonate in DMF medium. These compounds were screened for their antitumor activity. Our results show that treatment of imidazole derivatives inhibit proliferation EAT cells, decreases the ascites volume and increases the survivability of the animals in vivo. These compounds also inhibited the cellular proliferation of HUVEC cells in vitro by MTT assay. Further, these compounds could induce apoptosis, which is evident by the nuclear condensation of imidazole derivatives treated EAT cells in vivo by the cytological analysis. We have identified that pyrrolidine substituted imidazole derivative as potent anti-tumor compound. These inhibitors could represent as promising candidates for anticancer therapies, where the formation of peritoneal malignant ascites is a major cause of morbidity and mortality.

Novel Ru(II) Complex with 1H-Benzo[d]Imidazole Derivative for Dye-Sensitized Solar Cell

It was reported that ruthenium(II) complex CBTR with 1H-benzo[d]imidazole derivative for heteroleptic donor system exhibited an enhancement of the solar cell performance, compared to N3. We took a theoretical approach about the CBTR dye. Density functional theory (DFT) and time-dependent density functional theory (TD-DFT) calculations were used to gain insight into the factors responsible for the photovoltaic properties of the dye sensitizer. The values of the absorption spectrum of the CBTR dye with the 1H-benzo[d]imidazole derivative were not improved compared to those of the N3 dye. The lack of improvement was attributed to the destabilization of the lowest unoccupied molecular orbital (LUMO) energy level of the CTBR dye. According to the molecular orbital analysis, the LUMO of the CBTR dye mainly localized on the dcbpy (dcbpy = 4,4′-dicarboxy-2,2′-bipyridine) moiety. The highest occupied molecular orbitals (HOMOs) of N3 were localized on the Ru-NCS moiety, and the HOMOs of CBTR were also localized on Ru-NCS. The introduction of the 1H-benzo[d]imidazole derivative to the heteroleptic donor system did not change the location of the HOMOs. The addition on of the NHC ligand to the CBTR dye seems to be an essential structural modification to enhance the efficiency of solar cells.

Isoprene-Mediated Lithiation of 1-Alkylimidazoles: Chiral Induction of the Alkyl Substituent

The isoprene-mediated lithiation of imidazoles bearing a secondary alkyl substituent at the nitrogen (7, 8 and 13) and the subsequent nucleophilic addition to different electrophiles allows the preparation of the corresponding 2-functionalized imidazoles 10, 11 and 14. The presence of a stereogenic center in the alkyl substituent induces diastereoselection during the nucleophilic addition step with a prochiral electrophile (i.e. pivalaldehyde), producing the expected imidazole derivative with excellent overall yield, but low de (up to 26%).

Interaction of human serum albumin with novel imidazole derivatives studied by spectroscopy and molecular docking

This study was a detailed characterization of the interaction of a series of imidazole derivatives with a model transport protein, human serum albumin (HSA). Fluorescence and time-resolved fluorescence results showed the existence of a static quenching mode for the HSA-imidazole derivative interaction. The binding constant at 296 K was in the order of 10(4) M-1, showing high affinity between the imidazole derivatives and HSA. A site marker competition study combined with molecular docking revealed that the imidazole derivatives bound to subdomain IIA of HSA (Sudlow’s site I). Furthermore, the results of synchronous, 3D, Fourier transform infrared, circular dichroism and UV-vis spectroscopy demonstrated that the secondary structure of HSA was altered in the presence of the imidazole derivatives. The specific binding distance, r, between the donor and acceptor was obtained according to fluorescence resonance energy transfer. Copyright (c) 2015 John Wiley & Sons, Ltd.

TERMINATION OF DIAPAUSE IN PHARATE 1ST-INSTAR LARVAE OF THE GYPSY-MOTH LYMANTRIA-DISPAR-JAPONICA BY AN IMIDAZOLE DERIVATIVE KK-42

1-Benzyl-5-[(E)-2,6-dimethyl-1,5-heptadienyl] imidazole (KK-42) terminated diapause in pharate first-instar larvae of the gypsy moth, Lymantria dispar japonica. This effect of KK-42 was not prevented with juvenile hormone III and its analogs (methoprene and S-31183). In addition, free ecdysteroid titers were lower in diapausing eggs and the eggs treated with KK-42. These results indicate that KK-42 has the same function as in the breakdown of diapause of pharate first-instar larvae in the wild silkmoth, Antheraea yamamai.

Isoprene-mediated lithiation of imidazole derivatives: mechanistic considerations

The isoprene-mediated lithiation, with lithium metal, of different imidazole derivatives is an interesting methodology for their functionalization. Studies of different possible intermediates involved in the reaction employing density functional theory calculations, at the B3LYP/6-311++G(d,p) level are considered. A plausible mechanism is described, in which isoprene is reduced, to the corresponding radical anion, in the presence of Li-(s), acting then as a base deprotonating N-methylimidazole (NMI) and producing the 1,1-dimethylallyl radical. This radical is further reduced by the excess of lithium proceeding once more as a base. This final step produces stable final products that compensate the previous equilibriums, making favourable the whole process.

Fluorescence spectral studies of some imidazole derivatives

The photophysical properties of imidazole derivatives namely 2-(2,4-difluorophenyl)-4,5-dimethyl-1-p-tolyl-1H-imidazole and N,N-dimethyl-4-(4,5-dimethyl-2-phenyl-1H-imidazol-1-yl)benzenamine,synthesized from an unusual four components assembling, were studied in several solvents. Polarization also plays major role in the increase of excited-state dipole moment (mu(e)). From the spectral results, it was found that there is equilibrium between neutral species and monocationic (MC) species in polar aprotic and polar protic solvents. The basicity of the solvent, C-beta or C-SB has a negative value, suggesting that the absorption and fluorescence bands shift to lower energies with increasing electron-donating ability of the solvent. Therefore, resonance structures 1b and 2b has the positive charge located at the nitrogen atom stabilized in basic solvents. (C) 2012 Elsevier B.V. All rights reserved.
