Perspektiven der Biothermodynamik III. Thermische Stabilität von Proteinen
Authors: Keller J. U. 
Published: November 2008

AbstractDie Anwendung von Begriffen und Methoden der Thermodynamik der Gleichgewichte und der Vorgänge auf Systeme und Prozesse der Biotechnologie hat zur Bildung eines neuen Fachgebietes geführt, der technischen Biothermodynamik. Der vorliegende Artikel ist der dritte einer Reihe, in der versucht wird, einen Überblick über die Grundlagen und Möglichkeiten, die dieses Gebiet dem Verfahrensingenieur eröffnen, zu geben und dies auch an einzelnen Beispielen zu demonstrieren. In diesem Artikel wird das Problem der thermischen Stabilität von Proteinen in Lösungen thermodynamisch analysiert. Dabei wird der Übergang eines Proteins aus seinem natürlichen Zustand in einen (beliebigen) denaturierten Zustand als quasichemische Reaktion modelliert. Als Beispiel wird die thermische Stabilität von Myoglobin in wässriger Lösung mit Hilfe kalorischer Messdaten analysiert. Dabei zeigt sich, dass dieses Protein sowohl bei zu hohen als auch zu niedrigen Temperaturen denaturiert.
A Comparative Study of the Use of Organoclay‐Based Formulations and Organic Amendment to Reduce the Leaching of the Herbicide MCPA in Soil
Authors: Cabrera Alegría , Trigo Carmen , Cox Lucía , Celis Rafael , Cornejo Juan 
Published: November 2008

AbstractMCPA (4‐chloro‐2‐methylphenoxyacetic acid) is an acidic herbicide widely used on olive crops in Spain. Due to its anionic form at natural soil pH, there is high risk of leaching and groundwater contamination by the use of this herbicide. The aim of this work was to study the effects of organoclay‐based formulations of MCPA and olive oil waste amendment on MCPA leaching in a sandy loam soil. For this purpose, batch adsorption and column leaching studies were performed. The organoclays used to prepare the clay‐based formulations of MCPA were obtained by treating Wyoming montmorillonite (SWy‐2) and Arizona montmorillonite (SAz‐1) with an amount of hexadecyltrimethylammonium (HDTMA) cation equal to 100% of the CEC of the montmorillonites. The organic residue used in this study was a solid waste from olive oil production (olive oil waste, OOW). The soil was amended with the organic residue at the rate of 10% (w/w). Batch release and column leaching studies indicated that organoclay‐based formulations of MCPA reduced the release rate and the leaching of the herbicide as compared to the use of a conventional formulation containing the herbicide in an immediately available form. The increase in soil organic matter of the soil upon amendment with the organic residue also resulted in greater adsorption and reduced leaching of MCPA in the soil. Accordingly, both the use of organoclay‐based formulations and the amendment of soil with OOW are proposed as efficient strategies to reduce extensive leaching losses associated with the application of MCPA in high‐risk scenarios, such as Mediterranean olive groves.
Catalytic Hydrogenolysis of Aromatic Ketones in Mixed Choline–Betainium Ionic Liquids

Published: November 2008

AbstractThe palladium‐catalyzed hydrogenolysis of aromatic ketones to alkylbenzenes was studied in mixtures of ionic liquids to explore the promotional effect of these reaction media. Choline‐based ionic liquids displayed complete miscibility with the aromatic ketone substrate at reaction temperature and a clear phase separation of the derived alkylbenzene product at room temperature. Selected ionic liquids were then assessed as reaction media in the hydrogenolysis of aromatic ketones over palladium catalysts. A binary mixture of choline and betainium bis(trifluoromethylsulfonyl)imide ionic liquids resulted in the highest conversion and selectivity values in the hydrogenolysis of acetophenone. At the end of the reaction, the immiscible alkylbenzene separates from the ionic liquid mixture and the pure product phase can be isolated by simple decantation. After optimization of the reaction conditions, high yields (>90 %) of alkylbenzene were obtained in all cases. The catalyst and the ionic liquid could be used at least three times without any loss of activity or selectivity.
Synthesis and Characterization of Novel Biopolyesters from Suberin and Model Comonomers
Authors: Sousa Andreia F. , Gandini Alessandro , Silvestre Armando J. D. , Pascoal Neto Carlos 
Published: November 2008

AbstractThe synthesis of novel polyesters from model long‐chain aliphatic monomers and from suberin reactive aliphatic fragments was conducted using mild polycondensation or polytransesterification conditions. The ensuing polyesters were characterized by means of various techniques. When mixtures of simple suberin‐like monomers were used, the ensuing polyesters had very regular structures, with melting temperatures around 80 °C and glass transitions below room temperature. This first systematic study of the exploitation of suberin as a precursor to novel aliphatic polyesters confirmed the huge potential of using this abundant renewable resource to prepare macromolecular materials for promising applications.
Expectancies related to thinness, dietary restriction, eating, and alcohol consumption in women with bulimia nervosa
Authors: Bruce Kenneth , Mansour Sandra , Steiger Howard 
Published: November 2008

AbstractObjective:To investigate behavior‐outcome expectancies relating to thinness, dietary restriction, eating, and alcohol consumption in women with bulimia nervosa (BN).Method:Women with BN (N = 29), women with BN and a co‐morbid lifetime alcohol use disorder (AUD; N = 18), and control women (N = 24), completed interviews and questionnaires assessing eating‐ and alcohol‐related symptoms, as well as questionnaires measuring expectancies relating to thinness, dietary restriction, eating, and alcohol consumption.Results:Compared with the control group, both bulimic groups reported greater positive expectancies relating to thinness, dietary restriction and eating; expectancy endorsements were also predictive of the severity of eating‐related symptoms. Compared with the other groups, the bulimic group with comorbid lifetime AUD had elevated positive alcohol‐related expectancies, and alcohol expectancy endorsements predicted severity of alcohol‐related symptoms.Discussion:Women with BN endorsed more positive expectancies relating to thinness, dietary restriction, and eating, whereas women with BN and a lifetime comorbid AUD endorsed more positive alcohol expectancies. The results are consistent with expectancy theory in that positive expectancy endorsements were associated with symptom severity in a syndrome‐specific manner. Expectancies related to thinness, dietary restriction, eating, and alcohol consumption in women with BN. © 2008 by Wiley Periodicals, Inc. Int J Eat Disord 2009
Regional development, nature production and the techno‐bureaucratic shortcut: the Douro River catchment in Portugal
Authors: Ioris Antonio A. R. 
Published: November 2008

AbstractThe introduction of the Water Framework Directive in Europe represents a unique opportunity to promote more inclusive strategies for the long‐term preservation of (socionatural) water systems. However, the analysis of the Portuguese experience, using the River Douro as a case study, reveals still considerable shortcomings in the assessment of problems and the formulation of solutions. Instead of promoting a meaningful dialogue between social groups and spatial areas, there is a systematic attempt to conform to legal requisites by taking a ‘techno‐bureaucratic’ shortcut that largely reproduces the distortions of previous regulatory approaches. Decisions on water management are part of political disputes about regional development and state reform, such as in relation to the provision of water and electricity by public utilities. Nonetheless, these broader issues have been kept tacitly away from the WFD agenda, which has been concentrated on adjusting established procedures to the (formal) requirements of the new regulation.

The Role of Functionalisation, Asymmetry and Shape of a New Macrocyclic Compartmental Ligand in the Formation of Mononuclear, Homo‐ and Heterodinuclear Lanthanide(III) Complexes
Authors: Tamburini Sergio , Sitran Sergio , Peruzzo Valentina , Vigato Pietro Alessandro 
Published: November 2008

AbstractThe compartmental [1+1] macrocycle H3L, obtained by self‐condensation of the formyl precursor 3,3′‐(3,6‐dioxaoctane‐1,8‐diyldioxy)bis(2‐hydroxybenzaldehyde) with the amine precursor N,N‐bis(2‐aminoethyl)‐2‐hydroxybenzylamine, contains one inner ON3O2 Schiff base and one outer O2O4 crown‐like chamber. According to the experimental conditions it forms, by a template process, the stable mononuclear complexes Ln(H3L)(Cl)2(CH3COO)·nS·mHCl or [Ln(L)]·nS (Ln = La, Lu, Y, Yb, Er, Dy, Tb, Gd, Eu, Ce) with the lanthanide(III) ion encapsulated in the crown‐ether‐like and in the Schiff base site. The mononuclear complexes Ln(H3L)(Cl)2(CH3COO)·nS·mHCl, by further complexation with a different lanthanide(III) ion, give rise to the related heterodinuclear complexes [LnLn′(L)(Cl)2(CH3COO)]·nS while the homodinuclear and the heterodinuclear complexes [Ln2(L)](Cl)3·nH2O and [LnLn′(L)](Cl)3·nS could be prepared by a template reaction using the appropriate molar ratio of reactants. Their properties have been studied by using SEM‐EDS microscopy, IR and NMR spectroscopy and their compositions confirmed by thermal and ESI‐Mass spectrometric analyses. In the heterodinuclear complexes, the site occupancy of the different lanthanide(III) ions was determined by 1H and 13C NMR spectroscopy in CD3OD or (CD3)2SO – it was found that heterodinuclear complexation occurs in methanol with the smaller lanthanide(III) ion mainly coordinating to the Schiff base site and the larger lanthanide(III) ion to the crown site whereas, in dimethyl sulfoxide, demetalation of the weaker coordinated lanthanide(III) ion into the crown ether chamber occurs with the subsequent formation of mononuclear species in solution. The thermal decomposition of the heterodinuclear complexes forms the related mixed oxides, the stoichiometries and properties of which were determined by SEM‐EDS microscopy and X‐ray powder diffraction studies (XRD).

Published: November 2008

AbstractTwo (polypyridyl)ruthenium(II) complexes, [(tpy)RuII(L)](PF6)2 (1) and [(tpy)RuII(L)RuII(tpy)](PF6)4 (2) {tpy is 2,2′:6′,2″‐terpyridine and L is 1,4‐bis[(2,6‐dipyrazol‐1‐yl)pyrid‐4‐yl]benzene}, were synthesised and studied in view of their electrochemical and photophysical properties. The structural characterisation of 1 and 2 was carried out by 1H and 13C NMR spectroscopy, MALDI‐TOF/ESI mass spectrometry and single‐crystal X‐ray analysis. The spectro‐ and electrochemical consequences of the introduction of 2,6‐dipyrazol‐1‐ylpyridine coordinating units into RuII polypyridyl complexes were investigated by UV/Vis, low‐temperature emission spectroscopy and square‐wave voltammetry. It was shown that ligand L can be used as a back‐to‐back bridging ligand in the construction of multinuclear ruthenium(II) ion arrays. In comparison to the widely used 2,2′:6′,2″‐terpyridyl system, the 2,6‐dipyrazol‐1‐ylpyrid‐4‐yl unit was found to act as a relatively strong σ‐donor and weak π‐acceptor ligand which allows its use as a structural and electronic alternative in multinuclear architectures.(© Wiley‐VCH Verlag GmbH & Co.

Total Synthesis of Candicanoside A, a Rearranged Cholestane Disaccharide, and Its 4″‐O‐(p‐Methoxybenzoate) Congener
Authors: Tang Pingping , Yu Biao 
Published: November 2008

AbstractCandicanoside A (1) and its 4″‐O‐(p‐methoxybenzoate) derivative 2 are congeners of the novel 24(23→22)abeo‐cholestane glycosides that occur in the genus Ornithogalum indigenous to Southern Africa and have remarkable cytostatic activities. These two saponins have been synthesized starting from dehydroisoandrosterone, D‐glucose, and L‐rhamnose in 37 and 44 steps, respectively. The reaction protocols feature a stereocontrolled stepwise glycosylation with glycosyl imidates as the donors. The synthesis of the rearranged steroid aglycon employs a 20‐alkoxy radical‐mediated functionalization of the angular 18‐methyl group, a Johnson–Claisen rearrangement for the alkylation at C‐20, an aldol condensation at C‐22, and a photodeconjugation of an α,β‐unsaturated lactone as the key steps.

New Route to the Synthesis of the Isocryptolepine Alkaloid and Its Related Skeletons Using a Modified Pictet–Spengler Reaction
Authors: Agarwal Piyush K. , Sawant Devesh , Sharma Sunil , Kundu Bijoy 
Published: November 2008

AbstractA new route to the synthesis of the isocryptolepine alkaloid with antimalarial activity using a modified Pictet–Spengler reaction has been devised. The strategy was then used to generate libraries based on three structural variants of the alkaloid. Compounds based on these three variants in general were accessed in three steps through a modified Pictet–Spengler cyclization reaction as the key step. The C‐2‐, C‐3‐, or N‐1‐linked (aminoaryl)indoles (8, 12, 13) required for cyclization were obtained by treating the corresponding indoles with o‐halonitrobenzene using either nucleophilic replacement or Pd‐based chemistry (Heck/Suzuki reaction) followed by reduction of the nitroaryl functionality. The substrates 8, 12, and 13 were then subjected to the Pictet–Spengler reaction to furnish polycyclic structures, indolo‐quinolines 4 and 19 and indolo‐quinoxalines 20 with three‐point diversity in high yields and purities. One of the indolo‐quinolines 4a after treatment with CH3I furnished the isocryptolepine alkaloid in excellent yield. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
