Studies on anhydrous proton conducting membranes based on imidazole derivatives and sulfonated polyimide

Anhydrous proton conducting membranes based on sulfonated polyimide (sPI) and imidazole derivatives were prepared. The acid-base composite membranes show a good chemical oxidation stability and high thermal stability. The addition of imidazole derivatives in sPIs can improve the chemical oxidation stability of the composite membranes enormously, and even much better than that of pure sPI. The proton conductivity of a typical sPI/xUI(2-undecylimidazole) composite membrane can reach 10(-3) S cm(-1) at 180 degrees C under the anhydrous condition. The proton conductivity of the acid-base composite membranes increases significantly with increasing content of UI. Moreover, UI in sPI/xUI composite membrane is difficult to be brought out by the vapor due to the existence of long hydrophobic moiety, which will improve the stability and lifetime of the membranes in the fuel cells.

Induction of non-diapause eggs by imidazole derivative KK-42 in the diapause type of Bombyx mori silkworm

The injection of an imidazole compound, KK-42, into fifth instar larvae of a silkworm (Bombyx mori, Daizo strain), which had been destined to produce diapause eggs, induced the moths to lay non-diapause eggs. The critical period for KK-42 injection in the induction of non-diapause eggs was 24 h to 72 h after the fourth ecdysis. Topical application of KK-42 to 48 h-old fifth instar larvae also induced non-diapause eggs.

Fabrication of one-component epoxy resin systems using maleic acid modified imidazole derivatives

A series of maleic acid modified imidazole derivatives (IM-MA, 2MI-MA and 2EI-MA) were synthesized via the Michael addition reaction of maleic acid (MA) with imidazole (IM), 2-methylimidazole (2-MI) and 2-ethylimidazole (2-EI), respectively. H-1 nuclear magnetic resonance (NMR), Fourier Transform Infrared (FTIR) spectra and Elemental analysis (EA) were used to verify the structure of maleic acid modified imidazole derivatives. The maleic acid modified imidazole derivatives were used as latent curing agents for epoxy resin (EP). Differential scanning calorimeter (DSC) under dynamic and isothermal condition was used to study the curing behavior of the prepared EP systems. The curing reactivity of maleic acid modified imidazole derivatives were significantly suppressed, compared with the common imidazole compounds. The EP systems containing maleic acid modified imidazole derivatives possessed excellent storage stability of at room temperature, due to the electron-withdrawing effect of carboxyl reduced the nucleophilicity of imidazole ring and the intermolecular hydrogen bond formed between carboxyl and 3-position nitrogen atom further restrained the nucleophilicity of imidazole ring. What’s more, the maleic acid modified imidazole derivatives regained fast curing ability towards EP under heating condition. Taking advantage of these characteristics, the maleic acid modified imidazole derivatives were suitable for preparing one-component EP systems.

HPLC retention and inclusion of imidazole derivatives using hydroxypropyl-beta-cyclodextrin as a mobile phase additive

Using the results of high performance liquid chromatography (HPLC), this paper investigates the separation and inclusion of a series of weakly polar imidazole derivatives, with hydroxypropyl-beta-cyclodextrin (HP-beta-CD) in the mobile phase over a wide range of column temperatures. These compounds are used for the treatment of onychomycosis. Gibbs Helmholtz parameters (Delta(Delta H) and Delta(Delta S)) of two adjacent imidazole peak on a chromatogram were determined from the graph of the logarithm of the separation factor, alpha, against the reciprocal of the temperature. A temperature dependent reversal of the elution order between a pair of imidazole derivatives was studied. The results revealed that the main parameter determining interactions between imidazole derivatives and HP-beta-CD increased as follows: HP-beta-CD double left right arrow solute hydrogen bonding interaction > HP-beta-CD double left right arrow solute complexation.

IMIDAZOLE DERIVATIVES AS CORROSION-INHIBITORS FOR ZINC IN HYDROCHLORIC-ACID

The efficiency of various imidazole derivatives as zinc corrosion inhibitors in hydrochloric acid (HCl) was investigated using electrochemical and gravimetric methods. A difference in efficiency (z) was observed with the introduction of different substituents into a imidazole skeleton. It was established that substituents which increased the electron density at the reaction center improved the corrosion inhibiting properties of the heterocyclic compound. A linear correlation between reaction kinetic data and the sum of the polar substituent constants was obtained.

The oxindole/imidazole derivative C16 reduces in vivo brain PKR activation

Inhibition of double-stranded RNA-dependent protein kinase (PKR) represents an interesting strategy for neuroprotection. However, inhibiting this kinase which triggers the apoptotic process could favour in counterpart cell proliferation and tumorigenesis. Here, we use an in vivo model of 7-day-old rat displaying a high activation of brain PKR to investigate the effects of a new PKR inhibitor identified as an oxindole/imidazole derivative (06). We show for the first time that acute systemic injection of C16 specifically inhibits the apoptotic PKR/eIF2 alpha signaling pathway without stimulating the proliferative mTOR/p7OS6K signaling mechanism.

Synthesis of chiral SalenZn(II) and its coordination with imidazole derivatives and amino acid ester derivatives

A chiral complex, SalenZn(II) ( S), was synthesized and characterized. Its coordination with imidazole derivatives and amino acid ester derivatives was studied by UV-vis spectrophotometric titrations and CD spectroscopy. The binding constants decreased in the order K (Im)> K (2-MeIm)> K (2- Et-4-MeIm)> K (N-MeIm) for imidazole derivatives, and K (AlaOMe)> K (PheOMe)> K (ValOMe) for amino acid ester derivatives with the same configuration and K-D> K-L for amino acid esters with different configuration. CD spectra can quantify the strength of SalenZn(II)-ligand interactions, giving results consistent with the magnitudes of the binding constants. Moreover the minimum energy conformations of the adducts were obtained by simulated annealing, and quantum chemical calculations were performed based on those conformations to explain experimental results at the molecular level.

Synthesis of a Series of Zinc Porphyrins and Spectroscopic Changes upon Coordination Reaction with Imidazole Derivatives

Three metal-free porphyrins modified with Boc-L-threonine and their zinc analogs were synthesized and characterized by elemental analysis, H-1 NMR, UV/vis, and fluorescence spectroscopies. The binding of imidazole derivatives to these zinc porphyrins was studied, with emphasis on the binding mechanism in CH2Cl2 solution, by means of UV/vis spectroscopy and quantum chemical methods. Both experimental results and theoretical calculations showed that a coordination reaction occurred between the zinc porphyrins and imidazole derivatives. The association constants between the zinc porphyrins and imidazole derivatives decreased in the order N-MeIm>Im. Increasing the temperature disfavored the interaction. Thermodynamic parameters calculated by the van’t Hoff equation showed that the driving force for the reaction was the enthalpy change. The fluorescence changes associated with the interaction between the zinc porphyrins and imidazole derivatives were also studied by fluorescence spectroscopy. The experimental results showed significant quenching between the various zinc porphyrins and imidazole derivatives.
