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.

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.

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%).

Synthesis of fused tetrazole- and imidazole derivatives via iodocyclization

The possibility to prepare fused tetrazole- and imidazole derivatives by iodocyclization in moderate to excellent yields is demonstrated. In some examples the cyclizations were not following Baldwin’s rules entirely, i.e. exo-selectivity. Nucleophilic substitution of the formed iodides gave different results depending on the hardness of the nucleophile. Thus, elimination of the iodide could be a problem but a substitution reaction with ethyl potassium xanthate and a radical reaction using acrylonitrile were tolerated. In addition, we showed that it is possible to selectively use three iodo substituents individually in one of the fused imidazole derivatives. (C) 2003 Elsevier Ltd. All rights reserved.

Antifugal Action of Imidazole Derivatives from New Pharmaceutical Forms on Various Strains of Candida

The antifungal activity of imidazole derivatives was tested on three types of Candida, respectively C. albicans, C. sake, and C. glabrata. The antifungal activity was compared with the activity of miconazole nitrate in 16 new formulations of oral biomucoadhesive tablets, with the purpose of being used in oral candidiasis. All the 16 formulations of biomucoadhesive tablets which contain 25 mg miconazole have a good antifungal action; the diameter of the inhibition area is over 20 mm in all the three strains of Candida. The second goal was to compare the activity of miconazole nitrate with other antifungal substances: clotrimazole (benzyl imidazole derivative), nistatin (polyenic macrolide), econazole (phenyl – ethyl – imidazole derivative), and fluconazole (triazole derivative). Good results, obtained by measuring the diameter of the inhibition area, were shown by econazole, with a diameter of over 22 mm, but this imidazole derivative does not penetrate the stratum corneum well enough, which implies a much longer treatment than miconazole. The third goal was the assessment of the antifungal activity of the 16 formulations of biomucoadhesive tablets by means of establishing the minimum inhibitory concentration (MIC) and of minimum fungicide concentration (MFC).

Application of 3543-73-5, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 3543-73-5.

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.

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.
