Synthesis and characterization of the biodegradable polycaprolactone‐graft‐chitosan amphiphilic copolymers
Authors: Yu Haijun , Wang Wenshou , Chen Xuesi , Deng Chao , Jing Xiabin 
Published: June 2006

AbstractA novel synthetic approach to biodegradable amphiphilic copolymers based on poly (ϵ‐caprolactone) (PCL) and chitosan was presented, and the prepared copolymers were used to prepare nanoparticles successfully. The PCL‐graft‐chitosan copolymers were synthesized by coupling the hydroxyl end‐groups on preformed PCL chains and the amino groups present on 6‐O‐triphenylmethyl chitosan and by removing the protective 6‐O‐triphenylmethyl groups in acidic aqueous solution. The PCL content in the copolymers can be controlled in the range of 10‐90 wt %. The graft copolymers were thoroughly characterized by 1H NMR, 13C NMR, FT‐IR and DSC. The nanoparticles made from the graft copolymers were investigated by 1H NMR, DLS, AFM and SEM measurements. It was found that the copolymers could form spherical or elliptic nanoparticles in water. The amount of available primary amines on the surface of the prepared nanoparticles was evaluated by ninhydrin assay, and it can be controlled by the grafting degree of PCL. © 2006 Wiley Periodicals, Inc.

Interactions between bovine serum albumin and gemini surfactant alkanediyl‐α, ω‐bis(dimethyldodecyl‐ammonium bromide)

Published: June 2006

AbstractInteractions between bovine serum albumin (BSA) and cationic gemini surfactant alkanediyl‐α,ω‐bis(dimethyldodecyl‐ammonium bromide) (12‐n‐12, n = 3, 4, 6) in aqueous solution have been investigated by measuring fluorescence, UV‐vis transmittance, dynamic lighting scattering, and circular dichroism. Compared to a traditional surfactant dodecyltrimethylammonium bromide (DTAB), 12‐n‐12 interacts with BSA more strongly. With increasing concentration, 12‐n‐12 first binds specifically onto BSA leading to the unfolding and aggregation of BSA, and the decrease in α‐helix content; and then forms micelle‐like complexes along the unfolded BSA chains. A gemini surfactant with a longer spacer has a larger effect on BSA unfolding due to a stronger hydrophobic interaction. © 2006 Wiley Periodicals, Inc.

Flash Pyrolysis Study of M2TNR (M: Carbohydrazide or Semicarbazide) by T‐jump/FTIR Spectroscopy
Authors: Sun Yuan‐Hua , Zhang Tong‐Lai , Zhang Jian‐Guo , Qiao Xiao‐Jing , Yang Li 
Published: June 2006

AbstractFlash pyrolysis of (CHZ)2TNR and (SCZ)2TNR was conducted by T‐jump/FTIR spectroscopy under 0.1 MPa Ar atmosphere. The results show that eleven IR‐active gas products obtained during flash pyrolysis process of the two title compounds are NO, CO, HCN, NH3, NO2, N2O, HNCO, HNO2, CO2, H2O and HCHO, of which NO and CO are the main gas products. The molar fraction of the individual product in the pyrolysis gas mixture was described as a function of time. At least some of the NO2, N2O and H2O can result from the oxidization reaction of NH3 during flash pyrolysis of (CHZ)2TNR. It can be concluded that the two compounds are not worthy of further in‐depth consideration of the adoption in detonators as eco‐friendly primary explosive, and should not be used as gas generation composition of automobile crash airbag system taking into account the toxicity.
Design, Synthesis and Biological Evaluation of Novel Etoposide Analogues as Cytotoxic Agents
Authors: Liu Ying‐Qian , Yang Hua , Tian Xuan 
Published: June 2006

AbstractFive novel compounds composed of etoposide and 5‐fluorouracil derivatives joined by an ester linkage were prepared and evaluated for their antitumor potential. Most of these analogues have exhibited promising in vitro cytotoxic activity against cell cultures of murine leukaemia P‐388 and human lung carcinoma A‐549. The results presented herein challenged the long‐standing structure‐activity relationships, which proposed that a free 4′‐hydroxyl group is essential structural requirement for etoposide‐like activity. And in addition, the 4′‐position was suggested to tolerate chemical modifications such as esterification. The preliminary testing results also indicated that the design and synthesis of these compounds were beneficial for therapeutic values of etoposide.
Synthesis, Structure and Magnetic Properties of a New Low‐Spin Iron(III) Complex [FeL3] {L = [HNC(CH3)]2C(CN)}
Authors: Nishijo Junichi , Nishi Nobuyuki 
Published: June 2006

AbstractHigh‐temperature treatment of acetonitrile with CaC2 and FeCl2 afforded crystals of the new iron(III) S = 1/2 low‐spin complexes [FeL3]ROH (R = CH3 or C2H5), whose crystal structures were determined by single‐crystal X‐ray structural analysis. The methanol complex consists of a one‐dimensional arrangement of the iron moieties, while each methanol molecule is separated from each other by the complexes. On the other hand, the ethanol complex contains a two dimensional arrangement of the iron moieties and one dimensionally aligned ethanol molecules elongated perpendicular to the sheet. Because of the large difference in the inter‐complex overlap patterns between the ligands, the two materials show quite different magnetic properties. The magnetism of the crystal containing ethanol is well described by the singlet–triplet model with the antiferromagnetic interaction 2J/kB = –7.5 K, while that containing methanol obeys the Curie law with a negligibly small Weiss temperature.(© Wiley‐VCH Verlag GmbH & Co.

Molecular and Electronic Structures of Homoleptic Nickel and Cobalt Complexes with Non‐Innocent Bulky Diimine Ligands Derived from Fluorinated 1,4‐Diaza‐1,3‐butadiene (DAD) and Bis(arylimino)acenaphthene (BIAN)

Published: June 2006

AbstractThe diimine complexes with bulky fluorinatedN‐substituents [NiII(FDAD)2]1and [CoII(FDAD)2]2[FDAD =N,N′‐bis(pentafluorophenyl)‐2,3‐dimethyl‐1,4‐diaza‐1,3‐butadiene]as well as diimine complexes with extended π system [NiII(FBIAN)2]3and [CoI(FBIAN)3]4(FBIAN = bis[N‐{3,5‐bis(trifluoromethyl)phenyl}imino]acenaphthene) were synthesized. Compound4represents the first complex with three bis(imino)acenaphthene ligands synthesized so far. The molecular structures of the complexes1–4were determined by X‐ray crystallography at 193 K. Complexes1,2and3comprise the divalent metal ions with pairs of radical monoanionic ligands, whereas4is best described as a cobalt(I) complex with two neutral (FBIAN)0and one (FBIAN)1–ligand in the radical monoanionic form. The electronic structures of the paramagnetic cobalt complexes2and4were investigated by SQUID measurements and X‐band EPR spectroscopy. Both complexes possess a doublet ground state, with electron density located mostly in the metal d‐orbitals. The doublet–quartet energy gap for4was established to be 159 cm–1.

Published: June 2006

AbstractBis‐cyclometalated analogs of tris(2,2′‐bipyridine)ruthenium(II), namely [RuIII(C∩N)2(N∩N)]PF6 complexes 3, are prepared in 52–57 % yield from the mono‐cyclometalated N,N‐dimethylbenzylamine (dmbaH) derivatives [RuII(dmba)(N∩N)(MeCN)2]PF6 (N∩N = bpy or phen) and mercurated 2‐phenylpyridinato‐ or 4‐(2‐tolyl)pyridinato (C∩N) species Hg(C∩N)Cl. Two new bis‐ruthenacycles studied by X‐ray crystallography revealed a C1 symmetry, with the C and N atoms of different C∩N ligands trans to the nitrogen atoms of the N∩N ligand. The reduction potential of the RuII/III feature of 3 is as low as ca.–0.2 V (vs. SCE in MeCN). Complexes 3 display a unique mediating ability in moving electrons from the reduced active site of PQQ‐dependent alcohol dehydrogenase (PQQ‐ADH) to an electrode with 1,2‐propanediol as a substrate at a working potential of +0.1 V.

Evaluating the spatial relationship of event‐related potential and functional MRI sources in the primary visual cortex
Authors: Whittingstall Kevin , Stroink Gerhard , Schmidt Matthias 
Published: June 2006

AbstractThe integration of electroencephalogram (EEG) recordings and functional magnetic resonance imaging (fMRI) can provide considerable insight into brain functionality. However, the direct relationship between neural and hemodynamic activity is still poorly understood. Of particular interest is the spatial correspondence between event‐related potential (ERP) and fMRI sources. In the current study we localized sources generated by a checkerboard stimulus presented to eight subjects using both EEG and fMRI. The location of the sources of the visual evoked potential (VEP) were estimated at each timepoint and compared to the location of peak fMRI activity. In the majority of participants we found that the N75 dipole location coincides with a region of positive blood oxygenation level‐dependent (BOLD) activation and the P100 dipole location coincides with a region of negative BOLD activation. These findings demonstrate the importance of including the negative BOLD response in combined EEG/fMRI studies. Hum Brain Mapp, 2007. © 2006 Wiley‐Liss, Inc.
