Synthesis and Nonlinear Optical Properties of Chromophores with 1,8‐Dimethoxy‐9,10‐dihydroanthracene and Ring‐locked Triene
Authors: Shi Zheng‐Wei , Li Ying , Lu Guo‐Yuan , Zhang Chao‐Zhi , Liu Fang 
Published: January 2007

Abstract The new chromophore molecules with nonlinear optical (NLO) properties were prepared by Knoevenagel condensation from 1,8‐dimethoxy‐4,5‐diformyl‐9,10‐dihydroanthracene and isophorone derivative in the presence of piperidine and acetic acid. In these chromophore, the ring‐locked trienes were employed as the conjugation bridge and electron acceptor in D‐π‐A units. The key intermediate dialdehyde was conveniently prepared via a three step reaction, in which 1,8‐dimethoxyanthraquinone was reduced with zinc/acetic acid and sodium/ethanol successively, followed by formylation with 1,1‐dichlorodimethyl ether in the presence of TiCl4. The solvatochromism indicate that they have higher second‐order nonlinear hyperpolarizability μβ values than the corresponding reference compound, without red shift of the charge transfer band.

Microcalorimetric Evaluation of the Effect of Kanamycin: An Analysis Based on the Median‐Effect Principle
Authors: Wang Li‐Heng , Fan Dai‐Di , Shang Long‐An , Shi Hui‐Juan , Ma Xiao‐Xuan , Mi Yu , Gu Li‐Feng , Xu Kang‐Zhen 
Published: January 2007

AbstractA study of the effect of drug, kanamycin, on the growth metabolism of recombinant Escherichia coli B1 was carried out by microcalorimeter monitoring of the metabolic activity of treated cells. Power‐time curves of growing recombinant Escherichia coli cell suspensions, treated with different kanamycin doses, were recorded. The extent of the effect was evaluated by changes in the slopes of the microcalorimetric curves and the kinetics of the drug action was interpreted from the time at which these changes reached their maximum values and maintained their maximum values. Experimental dose‐effect relationships conform to the median‐effect principle of the mass‐action law: fa/(1−fa)=(D/D50)m. A plot of y=lg[(fa)1−1]−1 versus x=lg D gives the slope m, D50 and R∞. The experimental results revealed that high concentration of kanamycin had an inhibitory effect on the growth of recombinant Escherichia coli B1 in the lg phase, and had a promoting effect in the stationary period. Moreover, it was demonstrated that microcalorimetry was a reliable method for the detection of modulatory effects in biology.
Volumetric, Ultrasonic and Transport Properties of Binary Liquid Mixtures Containing Dimethyl Formamide at 303.15 K
Authors: Syamala Vardhana , Raja Sekhar Damaramadugu , Siva Kumar Kasibhatta , Venkateswarlu Ponneri 
Published: January 2007

AbstractExcess volumes (VE), ultrasonic velocities (u), isentropic compressibility (ΔKs) and viscosities (η) for the binary mixtures of dimethyl formamide (DMF) with 1,2‐dichlorobenzene, 1,3‐dichlorobenzene, 1,2,4‐trichlorobenzene, o‐chlorotoluene, m‐chlorotoluene, p‐chlorotoluene, o‐nitrotoluene and m‐nitrotoluene at 303.15 K were studied. Excess volume data exhibit an inversion in sign for the mixtures of dimethyl formamide with 1,2‐ and 1,3‐dichlorobenzenes and the property is completely positive over the entire composition range for the mixtures of dimethyl formamide with 1,2,4‐trichlorobenzene, o‐nitrotoluene and m‐nitrotoluene. On the other hand, the quantity is negative for the mixtures of dimethyl formamide with chlorotoluenes. Isentropic compressibility (Ks) has been computed for the same systems from precise sound velocity and density data. Further, deviation of isentropic compressibility (ΔKs) from ideal behavior was also calculated. ΔKs values are negative over the entire volume fraction range in all the binary mixtures. The experimental sound velocity data were analysed in terms of Free Length Theory (FLT) and Collision Factor Theory (CFT). The viscosity data were analysed on the basis of corresponding state approach. The measured data were discussed on the basis of intermolecular interactions between unlike molecules.
Hydrogen Bonding Interaction of Formic Acid‐, Formaldehyde‐, Formylfluoride‐Nitrosyl Hydride: Theoretical Study on the Geometries, Interaction Energies and Blue‐ or Red‐Shifted Hydrogen Bonds
Authors: Liu Ying , Liu Wen‐Qing , Li Hai‐Yang , Yang Yong , Cheng Shuang 
Published: January 2007

AbstractThe hydrogen bonding interaction of formic acid‐, formaldehyde‐, formylfluoride‐nitrosyl hydride complexes was investigated by the density functional theory (DFT) andab initomethod in conjunction with 6‐311++G(2d,2p) basis set. The geometries, vibrational frequencies and interaction energies of the complexes were calculated by both standard and CP‐corrected methods respectively. Moreover, G3B3 method was employed to estimate the interaction energies. There are C–H···O, N–H···O, N–H···F blue‐shifted H‐bonds and red‐shifted O–H···O H‐bond in the complexes. Electron density redistribution and rehybridization contribute to the N–H and C–H blue shifts. All geometric reorganizations contribute to the N–H blue shifts and partial geometric reorganizations contribute to the C–H blue shifts. The geometric reorganizations of the complex C except (H(5)‐O(4)‐C(1) contribute to the O–H red shift. For the N–H blue shifts, the effect ofr(N–O) variation on the N–H blue shifts is larger than that of (H‐N‐O variation. Rehybridization plays a dominant role in the degree of N–H blue shifts, whereas the electron density redistribution contributes more to the degree of C–H blue shifts than the other effects do.
Preparation and Characterization of a Novel Benzimidazolium Brønsted Acid Ionic Liquid and Its Application in the Synthesis of Arylic Esters
Authors: Wang Yuan‐Yuan , Li Wei , Xu Cheng‐Di , Dai Li‐Yi 
Published: January 2007

AbstractA novel Brønsted acid task specific ionic liquid 1‐ethylbenzimidazolium tetrafluoroborate ([Hebim]BF4) with functional benzimidazolium cation was synthesized and characterized by 1H NMR, IR, MS spectra and elemental analysis. This novel ionic liquid was successfully used as dual solvent‐catalyst for the synthesis of arylic esters. Higher yields were obtained in the presence of [Hebim]BF4 in comparison with other imidazolium ionic liquids because of the good solubility of the aromatic alcohols and aromatic carboxylic acids in [Hebim]BF4. The product could be separated conveniently from the reaction system, and the ionic liquid could be easily reused after removal of water under vacuum. After 10 times reuse, the selectivity of the ester was still 100%.

Authors: Chen Gang , Gong Bo‐Lin , Bai Quan , Geng Xin‐Du 
Published: January 2007

AbstractBased on the monodisperse poly(glycidyl methacrylate‐co‐ethylenedimethacrylate) beads (PGMA/EDMA) with macropore as a medium, a new hydrophilic medium cation exchange (MCX) stationary phase for HPLC was synthesized by a new chemically modified method. The stationary phase was evaluated with the property of ion exchange, separability, reproducibility, hydrophilicity, effect of salt concentration, salt types, column loading and pH on the separation and retention of proteins in detail. It was found that it follows ion exchange chromatographic (IEC) retention mechanism. The measured bioactivity recovery for lysozyme was (96±5)%. The dynamic protein loading capacity of the synthesized MCX packings was 21.8 mg/g. Five proteins were almost completely separated within 6.0 min at a flow rate of 4 mL/min using the synthesized MCX resin. The MCX resin was also used for the rapid separation and purification of lysozyme from egg white with only one step. The purity and specific bioactivity of the purified lysozyme was found more than 95% and 70345 U/mg, respectively.

Authors: Liu Cai‐Hua , Yu Xin‐Yu , Liang Xue‐Zheng , Wang Wen‐Juan , Yang Jian‐Guo , He Ming‐Yuan 
Published: January 2007

AbstractAcetalization of glycol with carbonyl compounds was carried out catalyzed by cupric p‐toluenesulfonate. These carbonyl compounds included cyclohexanone, propionoaldehyde, n‐butyraldehyde, iso‐butyraldehyde, n‐valeral‐ dehyde, benzaldehyde and butanone. Satisfactory results were obtained:the conversions of these carbonyl compounds were more than 90%, the selectivities were higher than 99.1%, only 0.1% mole ratio of catalyst to substrate and 90 min were sufficient in most cases. The catalyst and products were separated easily by phase separation.

Published: January 2007

AbstractThe enhancement effect of 3‐mercaptopropionic acid capped gold nanoparticles (NPs) in drug delivery and as biomarkers of drug‐resistant cancer cells has been demonstrated through fluorescence microscopy and electrochemical studies. The results of cell viability experiments and confocal fluorescence microscopy studies illustrate that these functionalized Au NPs could play an important role in efficient drug delivery and biomarking of drug‐resistant leukemia K562/ADM cells. This could be explored as a novel strategy to inhibit multidrug resistance in targeted tumor cells and as a sensitive method for the early diagnosis of certain cancers. Our observations also indicate that the interaction between the functionalized Au NPs and biologically active molecules on the surface of leukemia cells may contribute the observed enhancement in cellular drug uptake.
