Modeling the large‐strain constitutive behavior of polycarbonate under isothermal and anisothermal conditions
Authors: Sweeney J. , Caton‐Rose P. , Coates P. D.
Published: April 2005

The tensile behavior of polycarbonate was studied at large strains below the glass‐transition temperature. Experiments were carried out at a series of constant temperatures and also under conditions of falling temperatures. The specimens necked with a natural draw ratio of approximately 2, and the study was mainly focused on the necked material. Isothermal experiments revealed an elastic mechanism that initiated beyond the natural draw ratio. A model consisting of an Eyring process and two Gaussian elastic mechanisms was found to be applicable to both the isothermal and anisothermal stress‐relaxation and stress–strain results. The same model also produced reasonable estimates of the stresses generated during the necking process. In addition, a simple relationship between the isothermal and anisothermal stress relaxation was demonstrated. © 2005 Wiley Periodicals, Inc. J Appl Polym Sci 96: 2105–2116, 2005
Structural characterization of human elastin derived peptides containing the GXXP sequence
Authors: Moroy Gautier , Alix Alain J. P. , Héry‐Huynh Stéphanie
Published: April 2005

The degradation of elastin, the insoluble biopolymer of tropoelastin, can lead to the production of small peptides. These elastin‐derived peptides (EDPs) are playing a key role in cellular behavior within the extracellular matrix, showing a great variety of biological effects such as chemotaxis, stimulation of cell proliferation, ion flux modifications, vasorelaxation, and inflammatory enzymes secretion. It has also been demonstrated recently that EDPs containing the GXXPG motif could induce pro‐MMP1 and pro‐MMP3 upregulation. Elastolysis could then cause collagen degradation and play an important role in the aging process. Many experimental studies have been devoted to EDPs, but their structure/activity relationships are not well elucidated yet. However, the assumption that their active conformation is a type VIII β‐turn on GXXP was highly suggested on the basis of predictive statistical calculations.

Investigation of the EDPs three‐dimensional (3D) structure would provide useful information for drug‐design strategies to propose specific inhibitors. The work presented here reports theoretical results obtained from molecular dynamics simulations performed over 128 human EDPs containing the GXXP motif. We show that all the peptides, for which the central residues are not glycines, adopt a canonical (or very close to) type VIII β‐turn structure on the GXXP sequence. Amino acids surrounding this motif are also important for the structural behavior. Any residue located before the GXXP motif (XGXXP) increases the β‐turn stabilization, whereas the residue located after GXXP (GXXPX) has no significant structural effect. Moreover, we show their biological activity can be correlated with their ability to exhibit a type VIII β‐turn conformation. © 2005 Wiley Periodicals, Inc. Biopoly 78: 206–220, 2005
Functional Analysis of the Aureothin Iterative Type I Polyketide Synthase
Authors: He Jing , Hertweck Christian
Published: April 2005

The modular‐type polyketide synthase (PKS) that is involved in aureothin (aur) biosynthesis represents one of the first examples in which a single PKS module (AurA) is used in an iterative fashion. Here we report on the heterologous expression of an engineered AurAB fusion protein that unequivocally proves the iterative nature of AurA. In addition, point mutations reveal that aur PKS module 4 participates in polyketide biosynthesis despite its aberrant acyltransferase domain.
Triplet–Triplet Energy Transfer Controlled by the Donor–Acceptor Distance in Rigidly Held Palladium‐Containing Cofacial Bisporphyrins

Published: April 2005

Eleven new complexes, including mono‐, heterobi‐, and homobimetallic cofacial bisporphyrins, (Pd)H2DPS, (M)H2DPX, (M)H2DPB, (PdZn)DPS, (PdZn)DPX, (Pt)2DPX, (M)2DPB (M=Pd, Pt), and (Pt)P (DPS4−=4,6‐bis[5‐(2,8,13,17‐tetraethyl‐3,7,12,18‐tetramethylporphyrinyl)]dibenzothiophene tetraanion, DPX4−=4,5‐bis[5‐(2,8,13,17‐tetraethyl‐3,7,12,18‐tetramethylporphyrinyl)]‐9,9‐dimethylxanthene tetraanion, DPB4−=1,8‐bis[5‐(2,8,13,17‐tetraethyl‐3,7,12,18‐tetramethylporphyrinyl)]biphenylene tetraanion, P2−=5‐phenyl‐2,8,13,17‐tetraethyl‐3,7,12,18‐tetramethylporphyrin dianion) have been synthesized and characterized. The photophysical properties of the donor (M)P (M=Pd or Pt, P=porphyrin chromophore) and the acceptor (free base H2P or (Zn)P) depend on the Cmeso–Cmeso distance and the presence of a heavy atom such as PdII or PtII. The data were compared with those for the known compounds (Pd)2DPS, (Pd)2DPX, H4DPS, H4DPX, H4DPB, (Pd)P, (Zn)P, and H2P. The rate constants for triplet–triplet energy transfer (kET) were measured for the heterobimetallic (PdZn) and monometallic [(M)H2] derivatives (M=Pd, Pt). The fluorescence lifetimes (ΔτF) of the acceptors decrease as a result of the heavy‐atom effect, and vary as follows: (Pd)H2DPS≪(Pd)H2DPX∼(Pd)H2DPB. The kET values calculated according to the equation kET=(1/τemi−1/τemi0), where τemi0 is the emission lifetime of the homobimetallic bisporphyrins (no ET occurs), are equal to 0, 247±57 and 133±52 s−1 for DPS, DPX, and DPB, respectively, in the (Pd)H2 series. These measurements allowed the range of distance over which the Dexter mechanism for T1–T1 energy transfer ceases to operate to be determined. This distance is somewhere between 4.3 and 6.3 Å, in agreement with our recent findings on singlet–singlet energy transfer. During the course of this study, the X‐ray crystal structure for (Pd)H2DPX was obtained; triclinic (P$\bar 1$), a=11.1016(1), b=14.9868(2), c=20.6786(3) Å, α=102.091(1), β=100.587(1), γ=101.817(1)°, V=3199.19(7) Å3, Z=2.
Dichlororuthenium(IV) Complex of meso‐Tetrakis(2,6‐dichlorophenyl)porphyrin: Active and Robust Catalyst for Highly Selective Oxidation of Arenes, Unsaturated Steroids, and Electron‐Deficient Alkenes by Using 2,6‐Dichloropyridine N‐Oxide
Authors: Zhang Jun‐Long , Che Chi‐Ming
Published: April 2005

[RuIV(2,6‐Cl2tpp)Cl2], prepared in 90 % yield from the reaction of [RuVI(2,6‐Cl2tpp)O2] with Me3SiCl and structurally characterized by X‐ray crystallography, is markedly superior to [RuIV(tmp)Cl2], [RuIV(ttp)Cl2], and [RuII(por)(CO)] (por=2,6‐Cl2tpp, F20‐tpp, F28‐tpp) as a catalyst for alkene epoxidation with 2,6‐Cl2pyNO (2,6‐Cl2tpp=meso‐tetrakis(2,6‐dichlorophenyl)porphyrinato dianion; tmp=meso‐tetramesitylporphyrinato dianion; ttp=meso‐tetrakis(p‐tolyl)porphyrinato dianion; F20‐tpp=meso‐tetrakis(pentafluorophenyl)porphyrinato dianion; F28‐tpp=2,3,7,8,12,13,17,18‐octafluoro‐5,10,15,20‐tetrakis(pentafluorophenyl)porphyrinato dianion). The “[RuIV(2,6‐Cl2tpp)Cl2]+2,6‐Cl2pyNO” protocol oxidized, under acid‐free conditions, a wide variety of hydrocarbons including 1) cycloalkenes, conjugated enynes, electron‐deficient alkenes (to afford epoxides), 2) arenes (to afford quinones), and 3) Δ5‐unsaturated steroids, Δ4‐3‐ketosteroids, and estratetraene derivatives (to afford epoxide/ketone derivatives of steroids) in up to 99 % product yield within several hours with up to 100 % substrate conversion and excellent regio‐ or diastereoselectivity. Catalyst [RuIV(2,6‐Cl2tpp)Cl2] is remarkably active and robust toward the above oxidation reactions, and turnover numbers of up to 6.4×103, 2.0×104, and 1.6×104 were obtained for the oxidation of α,β‐unsaturated ketones, arenes, and Δ5‐unsaturated steroids, respectively.
Control of Helix Sense by Composition of Chiral–Achiral Copolymers of N‐Propargylbenzamides
Authors: Tabei Junichi , Shiotsuki Masashi , Sato Takahiro , Sanda Fumio , Masuda Toshio
Published: April 2005

N‐Propargylbenzamides 1–7 were polymerized with (nbd)Rh+[η6‐C6H5B−(C6H5)3] to afford polymers with moderate molecular weights (Mn = 26 000–51 000) in good yields. The 1H NMR spectra demonstrated that the polymers have fairly stereoregular structures (81–88 % cis). The optically active polymers, poly(1) and poly(2), were proven by their intense CD signals and large optical rotations to adopt a stable helical conformation with an excess of one‐handed screw sense when heated in CHCl3 or toluene. The sign of Cotton effect could be controlled by varying the content in the copolymers of either chiral bulky 1 and achiral nonbulky 3, or chiral nonbulky 2 and achiral bulky 7. The smaller the pendant group in the copolymerization of achiral monomers with 1, the more easily did the preferential helical sense change with the copolymer composition. However, the copolymers of chiral nonbulky 2 and achiral nonbulky 3 did not change the helical sense, irrespective of the composition. The free energy differences between the plus and minus helical states, as well as the excess free energy of the helix reversal, of those chiral–achiral random copolymers were estimated by applying a modified Ising model.
Intervalence Charge Transfer (IVCT) in Ruthenium Dinuclear and Trinuclear Assemblies Containing the Bridging Ligand HAT {1,4,5,8,9,12‐hexaazatriphenylene}
Authors: D'Alessandro Deanna M. , Keene F. Richard
Published: April 2005

The IVCT characteristics of the mixed‐valence forms of the dinuclear [{Ru(bpy)2}2(μ‐hat)]n+ and the trinuclear [{Ru(bpy)2}3(μ‐hat)]n+ species {HAT=1,4,5,8,9,12‐hexaazatriphenylene; bpy=2,2′‐bipyridine} show a marked dependence on the nuclearity, and in the trinuclear case on the extent of oxidation. Small differences are also found between the diastereoisomers of the dinuclear complex {meso (ΔΛ) and rac (ΔΔ/ΛΛ)}, and between the homochiral (Δ3/Λ3) and heterochiral (Δ2Λ/Λ2Δ) diastereoisomers of the trinuclear case. The strong metal–metal interactions result in unusual spectroscopic and electrochemical properties of the singly‐oxidised (+7) and doubly‐oxidised (+8) trinuclear mixed‐valence species. A qualitative localised bonding description based on the geometrical properties of the dπ(RuII/III) orbitals is invoked to explain the IVCT behaviour in the di‐ and trinuclear systems.
Heteroditopic Ligand Accommodating a Fused Phenanthroline and a Schiff Base Cavity as Molecular Spacer in the Study of Electron and Energy Transfer

Published: April 2005

The synthesis and characterisation of the heteroditopic ligand N,N′‐bis(3,5‐di‐tert‐butylsalicylidene)‐5,6‐(1,10‐phenanthroline)diamine (DPSalH2) bearing a phenanthroline and a bis(salicylidene)diimine cavity are reported. This versatile ligand combines two of the most widely used ligands in coordination chemistry. Sequential metallation of the phenanthroline end with RuII and the salophenic cavity with CuII is described. Electrochemical behaviour of the supramolecular complexes [Ru(bpy)2(DPSalH2)]2+ and [Ru(bpy)2(DPSalCu)]2+ are analysed in connection with UV/Vis and EPR spectroscopy. The data for the one‐electron‐reduced species and the singly oxidised species of the binuclear RuII–CuII complex confirmed the formation of metalloradical complexes. Density functional calculations on the free ligand and the copper‐only complex indicate in both cases that the HOMOs and LUMOs are developed on the Schiff base cavity with minor contributions on the bipyridine end. These findings support a bichromophoric character for our ruthenium complexes in the ground state, a necessary condition in the design of supramolecular systems for the study of electron transfer. Photophysical studies indicate fast quenching of the triplet excited state in both complexes, which suggests strong intercomponent excited‐state interactions. Evidence is presented that this quenching is due to intramolecular electron transfer, at least in the case of [Ru(bpy)2(DPSalH2)]2+, for which a charge‐separated state with a remarkable lifetime of about 30 μs was observed.
Molecular Conformation and Packing of Peptide β Hairpins in the Solid State: Structures of Two Synthetic Octapeptides Containing 1‐Aminocycloalkane‐1‐Carboxylic Acid Residues at the i+2 Position of the β Turn

Published: April 2005

Peptide β‐hairpin formation is facilitated by centrally positioned D‐Pro‐Xxx segments. The synthetic peptides Boc‐Leu‐Phe‐Val‐D‐Pro‐Ac6c‐Leu‐Phe‐Val‐OMe (1) and Boc‐Leu‐Phe‐Val‐D‐Pro‐Ac8c‐Leu‐Phe‐Val‐OMe (2) were synthesized in order to explore the role of bulky 1‐aminocycloalkane‐1‐carboxylic acid residues (Acnc, where n is the number of carbon atoms in the ring), at the i+2 position of the nucleating β turn in peptide β hairpins. Peptides 1 and 2 crystallize in the monoclinic space group P21 with two molecules in the asymmetric unit. The crystal structures of 1 and 2 provide conformational parameters for four peptide hairpin molecules. In all cases, the central segments adopts a type II′ β‐turn conformation, and three of the four possible cross‐strand hydrogen bonds are observed. Fraying of the hairpins at the termini is accompanied by the observation of NH⋅⋅⋅π interaction between the Leu(1)NH group and Phe(7) aromatic group. Cross strand stabilizing interactions between the facing residues Phe(2) and Phe(7) are suggested by the observed orientation of aromatic rings. Anomalous far‐UV CD spectra observed in solution suggest that close proximity of the Phe rings is maintained even in isolated molecules. In both peptides 1 and 2, the asymmetric unit consists of approximately orthogonal hairpins, precluding the formation of a planar β‐sheet arrangement in the solid state. Solvent molecules, one dioxane and one water in 1, three water molecules in 2, mediate peptide association. A comparison of molecular conformation and packing motifs in available β‐hairpin structures permits delineation of common features. The crystal structures of β‐hairpin peptides provide a means of visualizing different modes of β‐sheet packing, which may be relevant in developing models for aggregates of polypeptides implicated in disease situations.

The synthesis of highly strained bicyclic phosphirane and phosphirene iron–tetracarbonyl complexes, that is, complexes with 2‐aza‐1‐phosphabicyclo[n.1.0]alkanes and ‐alkenes (n=3–5), is explored by using intramolecular cycloaddition of an in situ generated electrophilic phosphinidene complex, [R(iPr)NPFe(CO)4], to its CC‐ and CC‐containing R substituent. Saturated bicyclic complexes 7 a–c with n=4–2 are remarkably stable, as illustrated by the X‐ray crystal structure for 7 b (n=3), yet all readily undergo retroaddition to react with phenylacetylene. Shuttling of the phosphinidene iron complex between two equivalent CC groups is demonstrated for a 1‐butene‐substituted 2‐aza‐1‐phosphabicyclo[3.1.0]hexane by selective 1H NMR magnetization transfer from the phosphirane protons to the olefinic protons. Even the more strained unsaturated bicycles 17 a,b (n=4,3) are surprisingly stable as illustrated by the X‐ray crystal structure for 17 a (n=4), but the smaller phosphabicyclo[3.1.0]hex‐5‐ene (17 c, n=2) dimerizes to tricyclic 19 with a unique ten‐membered heterocyclic ring; an X‐ray crystal structure is reported. Like their saturated analogues also the bicyclic phosphirenes readily undergo retroaddition as shown by the reaction of their phosphinidene iron moiety with phenylacetylene.
Rhodium‐Catalyzed Nondecarbonylative Addition Reaction of ClCOCOOC2H5 to Alkynes
Authors: Hua Ruimao , Onozawa Shun‐ya , Tanaka Masato
Published: April 2005

Addition of ethoxalyl chloride (ClCOCOOEt) to terminal alkynes at 60 °C in the presence of a rhodium(I)–phosphine complex catalyst chosen from a wide range affords 4‐chloro‐2‐oxo‐3‐alkenoates regio‐ and stereoselectively. Functional groups such as chloro, cyano, alkoxy, siloxy, and hydroxy are tolerated. The oxidative addition of ethoxalyl chloride to [RhCl(CO)(PR3)2] proceeds readily at 60 °C or room temperature and gives [RhCl2(COCOOEt)(CO)(PR3)2] (PR3 = PPh2Me, PPhMe2, PMe3) complexes in high yields. The structure of [RhCl2(COCOOEt)(CO)(PPh2Me)2] was confirmed by X‐ray crystallography. Thermolysis of these ethoxalyl complexes has revealed that those ligated by more electron‐donating phosphines are fairly stable against decarbonylation and reductive elimination. [RhCl2(COCOOEt)(CO)(PPh2Me)2] reacts with 1‐octyne at 60 °C to form ethyl 4‐chloro‐2‐oxo‐3‐decenoate. The catalysis is therefore proposed to proceed by oxidative addition of ethoxalyl chloride, insertion of an alkyne into the ClRh bond of the resulting intermediate, and reductive elimination of alkenyl‐COCOOEt.
Metal‐Induced Chiral Folding of Depsipeptide Dendrimers
Authors: Buschhaus Boris , Hampel Frank , Grimme Stefan , Hirsch Andreas
Published: April 2005

The synthesis and metal complexation of chiral depsipeptide dendrimers 3 and 7 containing an ethylenediaminetetraacetic acid (EDTA) ester‐derived core is reported. The EDTA ester cavity of these dendrimers selectively complexes Zn2+ and Cu2+ ions leading to diastereoselective folding. To elucidate the coordination motif in the resulting “foldamers” of 3‐ZnCl2, 7‐ZnCl2, 3‐CuCl2, and 7‐CuCl2, the coordination behavior of the tetramethyl ester of EDTA (8) has been investigated as a model case. The corresponding complexes 8‐ZnCl2 and 8‐CuCl2 have been structurally characterized by 1H NMR spectroscopy and X‐ray analysis. The complexes involve the inherently chiral octahedral cis‐α coordination motif, in which 8 serves as a tetradentate ligand. In the case of the ZnII complex 8‐ZnCl2, both Δcis‐α(S,S,λ) and Λcis‐α(R,R,λ) stereoisomers were found in the unit cell. For the CuII complex 8‐CuCl2, only one stereoisomer, namely Δcis‐α(S,S,λ) was found in the crystal under investigation. 1H NMR spectroscopy has shown that the same coordination motif is diastereoselectively formed in the chiral Zn2+ dendrimers 3‐ZnCl2 and 7‐ZnCl2. Likewise, the calculated CD spectrum of the Δcis‐α(S,S,λ) stereoisomer of the model complex 8‐CuCl2 shows good agreement with the experimental spectrum of the CuII dendrimers 3‐CuCl2 and 7‐CuCl2, allowing assignment of the absolute configurations of the preferred foldamers as Λcis‐α(R,R,λ) for 3‐CuCl2 and Δcis‐α(S,S,λ) for 7‐CuCl2. This work represents the first example of metal‐complexation‐mediated diastereoselective folding of chiral dendrimers with known absolute configuration.
Atom‐Type Assignment in Molecules and Clusters by Perturbation Theory—A Complement to X‐ray Structure Analysis
Authors: Weigend Florian , Schrodt Claudia
Published: April 2005

An approach to distinguish elements with similar atomic numbers in molecules and clusters is presented and applied to experimentally synthesized and structurally characterized mixed‐metallic compounds. By first treating a homogenized reference system constructed from the original compound and applying first‐order perturbation theory it is possible to find the most stable distribution of the atom types to the atomic sites in a very efficient way. This work is focused on the appropriate choice of homogenized reference systems and on applications treating experimentally synthesized compounds. With these examples is shown that the method is a helpful complement to X‐ray crystal structure analysis.
Facilitating Participation: Adults' Caring Support Roles within Child‐to‐Child Projects in Schools and After‐School Settings
Authors: Kirby Perpetua , Gibbs Sara
Published: April 2005

Embedded hierarchical relationships between children and adults constrain children's voice. For adults to support children's participation in decisions they need to learn new ways of working; to enable children to communicate their views, develop their ideas, make group decisions and take joint action. This article explores the different roles that caring professionals adopt when facilitating children's participation within Child‐to‐Child community health projects. It shows how even committed adults can struggle with shifting their practice and highlights the importance of facilitators adopting a reflective approach rooted in genuine dialogue with children in order to determine the most appropriate level of adult support.
