Published: March 2008

Aim. To study the pharmacokinetics of dihydroartemisinin (DHA) in Artekin (compound dihydroartemisinin) tablets in Chinese healthy volunteers. Methods. Eighteen healthy volunteers (9 males, 9 females) received Artekin tablets for oral administration. The plasma samples of DHA were analysed by liquid–liquid extraction and determined by HPLC/ESI/MS. Results. The plasma DHA concentration–time curves of single dose and repeated doses of DHA were fitted to a two‐compartment open model. The mean pharmacokinetic parameters of DHA in a single dose were: t1/2(β)=1.245 ± 0.495 h, Cmax=243.6 ± 56.15 µg/l, AUC0 → ∞=450 ± 69 h × µg/l, Vd=5.75 ± 2.2 l/kg and Cl=3.245 ± 0.38 l/h/kg, while in repeated doses they were: t1/2(β)=1.085 ± 0.298 h, AUC0 → ∞=444.35 ± 80.43 h × ng/ml, Vd=4.62 ± 1.128 ml/kg, Cl=3.0125 ± 0.875 ml/h/kg, respectively. Conclusion. The study showed that DHA in Artekin was rapidly absorbed, distributed and eliminated in the healthy subjects. The pharmacokinetic properties of DHA in Artekin were not affected by gender in a single dose. While in repeated doses accumulation of DHA did not appear after repeated doses.

Superiority of a new gradient system utilizing a critical threshold for the adsorption capacity of polypeptides to column packing when compared with a standard gradient system for the simultaneous and quantitative analysis of polypeptides
Authors: Goda Ryoya , Masumoto Hiroshi , Okazaki Osamu , Sudo Kenichi
Published: March 2008

Compared with a standard gradient system, the new gradient system which we developed has a major advantage because it permits a wide range of acetonitrile content, e.g. more than the critical threshold, in the polypeptide solution and allows the quantitative analysis of the polypeptide with satisfactory analytical precision. Additionally, this new gradient system allows the enhancement of the sensitivity of the polypeptide analysis proportionate to the increased volume of solution loaded with the same levels of precision. In contrast, when using a standard gradient system it is difficult to analyze a polypeptide quantitatively with good precision due to either adsorption to various materials or to irregular change in the ratio between a retained and a passed peak of the polypeptide. Additionally, the appearance of a passed peak results in a loss in the sensitivity of the polypeptide analysis, although no adsorption of a polypeptide to various materials occurs in a solution with acetonitrile content more than the critical threshold. Consequently, the new gradient system is effective for the simultaneous and quantitative analysis of different polypeptides with good precision and without any loss of sensitivity due to either adsorption to various materials or the appearance of a passed peak.

Modeling of the Ultrafiltration of a Dextran T500 Solution in a Tubular Membrane Module
Authors: Chikhi M. , Meniai A.‐H. , Balaska F. , Bencheikh‐Lehocine M.
Published: March 2008

Mathematical modeling of an ultrafiltration membrane separation process, based mainly on the transmembrane pressure (TMP), is undertaken in the present work. The main objective is the prediction of the permeate flux of a solution containing Dextran T500 through a cylindrical module. The proposed model incorporates the resistance‐in‐series model coupled with the equation describing the solute (Dextran T500) transport, as well as the continuity and Navier‐Stokes equations for solution flow modeling. The model equations are solved using finite‐volume numerical methods, with appropriate initial and boundary conditions. The effects of the TMP and the length of the membrane on the mean permeate flux were also investigated. The influence of the membrane dimensions (aspect ratio) on the relative dimensionless mean permeate flux, at different inlet TMPs and different solution concentrations, respectively, have also been considered. The variations of the TMP with the membrane length as well as the influence of the Peclet number on the solute surface concentration were also examined. The numerical results obtained are compared with experimental values reported in the literature, and in general, the agreement is satisfactory enough to encourage further refinement of the model.
Estimating the Bubble Point Pressure and Formation Volume Factor of Oil Using Artificial Neural Networks
Authors: Rasouli H. , Rashidi F. , Ebrahimian A.
Published: March 2008

The phase performance of hydrocarbons is a very complicated behavior that hydrocarbons show at the time of phase change or when they remain in a particular phase. Process design is almost impossible without a good understanding of this behavior. Artificial Neural Networks have been widely utilized for engineering applications during the last two decades. Two models are presented for the prediction of the bubble point pressure and the oil formation volume factor for hydrocarbon mixtures using the Artificial Neural Networks (ANNs) approach. For this purpose, five‐layer neural networks were designed and trained using 106 experimental data points. After the training step, 9 experimental data points were also used for the model evaluation step and as a reliability check. The output of the models for both the training and predicted data are compared with the empirical equations of Standing, Glaso and Marhoun. It is concluded that the ANNs approach has an excellent capability for these purposes compared to the conventional methods.
Comparative Study of Flow Structure in Circulating Fluidized Bed Risers with FCC and Sand Particles
Authors: Qi X.‐B. , Huang W.‐X. , Zhu J.
Published: March 2008

The combined influences of particle properties and nozzle gas distributor design on the axial and radial flow structure in two 100 mm i.d., 15.1 m and 10.5 m long risers with FCC and sand particles were investigated by measuring the axial pressure gradient profiles, and the axial and radial profiles of solids concentration. The results show that the nozzle gas distributor design has significant effects on the axial and radial flow structure for the FCC and sand particles. At lower superficial gas velocity of less than 8.0 m/s, the upward gas‐solid flow of the sand particles decelerates in various degrees with the disappearing of the nozzle gas distributor effect. The upward gas‐solid flow of the FCC particles, however, occurs without noticeable deceleration within the range of this study. In the acceleration section, the radial distributions of the local solids concentration of the FCC particles are more uniform than those of sand particles under the same operating conditions; while in the fully developed zone, the sand particles have a more uniform radial distribution than the FCC particles. The gas‐solid flow is first developed in the center region, and then extends towards the wall. The overall flow development in the riser mainly depends on the local gas‐solid flow in the wall region.
Homoleptic Copper(I) Arylthiolates as a New Class of p‐Type Charge Carriers: Structures and Charge Mobility Studies
Authors: Che Chi‐Ming , Li Cheng‐Hui , Chui Stephen Sin‐Yin , Roy V. A. L. , Low Kam‐Hung
Published: March 2008

Polymeric homoleptic copper(I) arylthiolates [Cu(p‐SC6H4‐X)]∞ (X=CH3 (1), H (2), CH3O (3), tBu (4), CF3 (5), NO2 (6), and COOH (7)) have been prepared as insoluble crystalline solids in good yields (75–95 %). Structure determinations by powder X‐ray diffraction analysis have revealed that 1–3 and 6 form polymers of infinite chain length, with the copper atoms bridged by arylthiolate ligands. Weak intra‐chain π⋅⋅⋅π stacking interactions are present in 1–3, as evidenced by the distances (3.210 Å in 1, 3.016 Å in 2, 3.401 Å in 3) between the mean planes of neighboring phenyl rings. In the structure of 6, the intra‐chain π⋅⋅⋅π interactions (d=3.711 Å) are insignificant and the chain polymers are associated through weak, non‐covalent CH⋅⋅⋅O hydrogen‐bonding interactions (d=2.586 Å). Samples of 1–7 in their polycrystalline forms proved to be thermally stable at 200–300 °C; their respective decomposition temperatures are around 100 °C higher than that of the aliphatic analogue [Cu(SCH3)]∞. Data from in situ variable‐temperature X‐ray diffractometry measurements indicated that the structures of both 1 and 7 are thermally more robust than that of [Cu(SCH3)]∞. TEM analysis revealed that the solid samples of 1–5 and [Cu(SCH3)]∞ contained homogeneously dispersed crystalline nanorods with widths of 20–250 nm, whereas smaller plate‐like nanocrystals were found for 6 and 7. SAED data showed that the chain polymers of 1–3 and [Cu(SCH3)]∞ similarly extend along the long axes of their nanorods. The nanorods of 1–5 and [Cu(SCH3)]∞ have been found to exhibit p‐type field‐effect transistor behavior, with charge mobility (μ) values of 10−2–10−5 cm2 V−1 s−1. Polycrystalline solid samples of 6 and 7 each showed a low charge mobility (<10−6 cm2 V−1 s−1). The charge mobility values of field‐effect transistors made from crystalline nanorods of 1–3 and [Cu(SCH3)]∞ could be correlated with their unique chain‐like copper–sulfur networks, with the para‐substituent of the arylthiolate ligand influencing the charge‐transport properties.

Disclosing elements of disclosure: a test of legitimacy theory and company ethics
Authors: Lightstone Karen , Driscoll Cathy
Published: March 2008

This paper focuses on some of the ethical issues related to voluntary disclosure of qualitative information by Canadian public companies. Drawing on various organizational theories, we examine some of the ways that companies can symbolically manage legitimacy through disclosure. Press releases of a sample of companies that received cease‐trading orders were analysed for their use of language. We found that high‐risk companies attempted to manage legitimacy by selectively releasing information and by using ambiguous language. Moreover, some companies behaved unethically by using language that suggested a positive future despite the imminent release of a cease‐trading order. These findings have implications for organizational and accounting theorists and stakeholders in the corporate, fiduciary, and investment communities. Copyright © 2008 ASAC.

The reaction of various indoles (1a–1k, 3 equiv.) with triethyl orthoformate (1.2 equiv.) catalyzed by I2 (5 mol%) at room temperature in 2–15 min under a solvent‐free condition afforded the respective symmetrical triindolylmethanes (3a–3k) in good to excellent yields without any side products.
Copper(II) and Cobalt(II) Dinuclear Complexes with Oxime‐based Ligand as Catalysts for the Hydrolysis of Phosphate Diester
Authors: DU Juan , MENG Xiang‐Guang , ZENG Xian‐Cheng
Published: March 2008

Dinuclear copper(II) and cobalt(II) complexes were prepared and investigated with respect to their effects on hydrolysis of bis(4‐nitrophenyl) phosphate (BNPP). The kinetic data indicated that the mono‐deprotonated oxime group could act as an effective intramolecular nucleophile in the reaction. The higher reactivity of dinuclear copper(II) complex than that of its mononuclear analogues illustrated the probability of double Lewis acid activation by two metal centers in the former complex.
Preparation, Crystal Structure and Thermal Analyses of 1,5‐Diamino‐4‐hydro‐1,2,3,4‐tetrazolium 3,5‐Dihydroxy‐2,4,6‐trinitrophenolate
Authors: CUI Yan , ZHANG Tong‐Lai , ZHANG Jian‐Guo , HU Xiao‐Chun , ZHANG Jin , HUANG Hui‐Sheng
Published: March 2008

A novel energetic salt 1,5‐diamino‐4‐hydro‐1,2,3,4‐tetrazolium 3,5‐dihydroxy‐2,4,6‐trinitrophenolate was synthesized by the reaction of 1,5‐diamino‐1,2,3,4‐tetrazole (DAT) with 2,4,6‐trinitro‐1,3,5‐trihydroxybenzene (trinitrophloroglucinol, TNPG). It was characterized by X‐ray single crystal diffraction, elemental analysis, FT‐IR spectroscopy and 1H NMR. The title compound crystallizes in monoclinic system, P2(1)/c space group with crystal parameters of a=1.3399(3) nm, b=0.47088(9) nm, c=2.0127(4) nm, β=92.83(3)°, V=1.2684(4) nm3, Z=4. Hydrogen bonds, electrostatic interactions, and weak van der Waals′ forces make the molecules form a stable three‐ dimensional net structure. Mulliken charge distribution and overlap population of DAT and DATH+TNPG− in bulk state have been obtained from the density functional theory (DFT) with the B3LYP method employing the 6‐31G∗︁ ∗︁ basis sets to interpret the reason why the protonation site of DAT is N(4) atom of the tetrazole ring. Thermal decomposition of the title compound was studied by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TG) techniques. The high enthalpy change and leaving no solid residue after thermal decomposition indicate that the title compound can be used as a promising energetic material or gas‐generating composition. The kinetic parameters of the exothermic process of DATH+TNPG− were studied by using Kissinger′s and Ozawa‐Doyle′s methods and the Arrhenius equation of this process was obtained.
Cinnamoylacetanilides and Their Metal Chelates
Authors: UMMATHUR Muhammed Basheer , KRISHNANKUTTY Krishnannair
Published: March 2008

A new series of β‐ketoanilides, in which the keto group attached to an olefinic linkage, have been synthesized by the reaction of acetoacetanilide with p‐substituted benzaldehydes (4‐methoxybenzaldehyde, 4‐ethoxybenzaldehyde, 4‐dimethylaminobenzaldehyde and 4‐nitrobenzaldehyde) under specified conditions. The existence of these β‐ketoanilides predominantly in the intramolecularly hydrogen bonded enol forms has been well demonstrated from their IR, 1H NMR and mass spectral data. Details on the formation of [ML2] complexes of these compounds with Ni(II), Cu(II) and Zn(II) and their nature of bonding were discussed on the basis of analytical, IR, 1H NMR and mass spectral data.
Morphology‐controlled Synthesis of SiO2 Hierarchical Structures Using Pollen Grains as Templates
Authors: GUAN Zi‐Sheng , ZHANG Yu , LU Chun‐Hua , XU Zhong‐Zi
Published: March 2008

Rape‐, sweet potato‐ and camellia‐pollen‐templated SiO2 hierarchical structures with species‐specific surface morphologies were prepared through a facile surface sol‐gel and succedent calcination process. Various‐morphology SiO2 replicas with complex structures, such as about 50‐µm‐length and 20‐µm‐width high‐fidelity ellipsoidal replicas with about 5‐µm uniform meshes, about 40‐µm spheres with 2‐µm taper‐like protuberances and 15‐µm spheres with troughs, were obtained from using rape‐, sweet potato‐ and camellia pollen grains as templates, respectively. The results of N2 adsorption‐desorption isotherms indicate that both rape‐ and camellia‐pollen‐ templated SiO2 replicas show type IV‐like isotherm with the characteristics of mesoporosity and corresponding Brunauer‐Emmett‐Teller (BET) surface areas are 10.5 and 5.2 m2·g−1, respectively. The Barrett‐Joyner‐Halenda (BJH) pore size distribution of the rape‐pollen‐templated SiO2 replicas presents smaller pores centered at 3.6 nm and bigger pores centered at 8.6 nm with a broad distribution whereas the camelliapollen‐templated SiO2 replicas display narrow BJH pore size distribution centered at 20 nm. The biofabrication procedure using ubiquitous, inexpensive and environment‐friendly pollen grains as a biotemplate holds a promise as a simple route to construct controlled complex porous oxides via simple chemical methods.

Published: March 2008

A copper coordination compound ZZF51(A) named bis(5‐butyl‐2‐pyridinecarboxylato‐N1,O2)‐copper, the first time found in the nature, was isolated from a marine endophytic fungus Fusarium sp. ZZF51 from the South China Sea coast. Its structure was elucidated using spectroscopic methods and single crystal X‐ray diffraction analysis. The antimicrobial cytotoxicity experiments exhibited that ZZF51(A) had mutagenicity activities against four aerobic reference strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Salmonella enteritidis with respective MIC values of 12.5, 25, 12.5, and 50 µg/mL. The anti‐cancer tests showed that the compound had strong inhibitory activities against three human cancer lines KB, KBv200, and HepG2 with IC50 values of 3.54, 3.68 and 25.12 µg/mL respectively. In the course of investigating the source of ZZF51(A) in biomass, it was found that the output of ZZF51(A) was largely influenced by the amount of CuCl2 in the liquid medium, and the fungus (No. ZZF51) had two notable characteristics:endurance of high concentration Cu(II) ions and biosorption of Cu(II) ions.
A New Route to Preparations of Silyl Ethers by Reactions of Silyl Triflimides with Alcohol or Ether
Authors: TANG Zi‐Long
Published: March 2008

A few of acyclic and cyclic silyl ethers were firstly synthesized in good yields by reactions of silyl triflimides with alcohol or ether. The corresponding silyl triflimides were easily produced by protodesilylation of phenyl or allyl silanes with HNTf2. All new compounds were characterized by 1H NMR, 13C NMR, MS, IR and HRMS.
