Recent Advances in Endomorphin Engineering
Authors: Keresztes Attila , Borics Attila , Tóth Géza 
Published: May 2010

AbstractRecent statistics from the World Health Organization indicate that a high percentage of people worldwide suffer from a wide variety of acute or cancer‐associated chronic pain. At present, with a few exceptions, the treatment of severe pain relies upon oral administration of the μ‐opioid receptor‐targeting opiate morphine and its surrogates under strict clinical control. In spite of the powerful in vivo efficacy of these drugs, their long‐term use is limited by antinociceptive tolerance, physical dependence, and respiratory depression that evolve. As no analgesics with moderate side effect profiles are currently available for the therapy of different types of pain and stages of cancer, considerable efforts must be made in the search for opiate substitutes. Following the recognition that endogenous peptide ligands of the opioid receptors exert striking effects in various pain models, and with the recent advances in chemical synthesis methods, research interest has steadily moved toward peptide‐based compounds as potential opioid analgesics. The endomorphins are an attractive set of endogenous opioid peptides that may meet the requirements of opioid‐based pain management. By virtue of their excellent μ‐opioid receptor labeling and favorable analgesic properties, these tetrapeptides have gained attention in recent years as potential lead compounds. The ever‐increasing number of publications in this field strongly suggests that modified analogues of endomorphins could serve as potent substitutes for opiates, with a lower propensity to induce side effects. This review surveys the main results achieved over the past decade regarding the design, radiolabeling, pharmacological characterization, and structure–activity features of a large body of endomorphin derivatives.
Homology Modelling of the GABA Transporter and Analysis of Tiagabine Binding
Authors: Skovstrup Søren , Taboureau Olivier , Bräuner‐Osborne Hans , Jørgensen Flemming Steen 
Published: May 2010

AbstractA homology model of the human GABA transporter (GAT‐1) based on the recently reported crystal structures of the bacterial leucine transporter from Aquifex aeolicus (LeuT) was developed. The stability of the resulting model embedded in a membrane environment was analyzed by extensive molecular dynamics (MD) simulations. Based on docking studies and subsequent MD simulations of three compounds, the endogenous ligand GABA and two potent inhibitors, (R)‐nipecotic acid and the anti‐epilepsy drug tiagabine, various binding modes were identified and are discussed. Whereas GABA and (R)‐nipecotic acid, which are both substrates, are stabilised with residues located deep inside the occluded state binding pocket (including residues Tyr 60 and Ser 396), tiagabine, which contains a large aliphatic side chain, is stabilised in a binding mode that extends from the substrate binding pocket (i.e., stabilised by Phe 294) to the extracellular vestibule, where the side chain is stabilised by aliphatic residues. The tiagabine binding mode, reaching from the substrate binding site to the extracellular vestibule, forces the side chain of Phe 294 to adopt a distinct conformation from that found in the occluded conformation of the transporter. Hence, in presence of tiagabine, GAT‐1 is constrained in an open‐to‐out conformation. Our results may be of particular interest for the design of new GAT‐1 inhibitors.
The Route to Functional Graphene Oxide

Published: May 2010

AbstractWe report on an easy‐to‐use, successful, and reproducible route to synthesize functionalized graphite oxide (GO) and its conversion to graphene‐like materials through chemical or thermal reduction of GO. Graphite oxide containing hydroxyl, epoxy, carbonyl, and carboxyl groups loses mainly hydroxyl and epoxy groups during reduction, whereas carboxyl species remain untouched. The interaction of functionalized graphene with fluorescent methylene blue (MB) is investigated and compared to graphite, fully oxidized GO, as well as thermally and chemically reduced GO. Optical absorption and emission spectra of the composites indicate a clear preference for MB interaction with the GO derivatives containing a large number of functional groups (GO and chemically reduced GO), whereas graphite and thermally reduced GO only incorporate a few MB molecules. These findings are consistent with thermogravimetric, X‐ray photoelectron spectroscopic, and Raman data recorded at every stage of preparation. The optical data also indicate concentration‐dependent aggregation of MB on the GO surface leading to stable MB dimers and trimers. The MB dimers are responsible for fluorescence quenching, which can be controlled by varying the pH value.
Structure of Glancing Incidence Deposited TiO2 Thin Films as Revealed by Grazing Incidence Small‐Angle X‐ray Scattering

AbstractFor the first time, grazing incidence small‐angle X‐ray scattering (GISAXS) analysis is used to characterize the morphology of TiO2 thin films grown by glancing angle physical vapor deposition (GLAD). According to cross‐section scanning electron microscopy (SEM) images, the films consist of near isotilted TiO2 columns of different length and width depending on film thickness. The obtained GISAXS patterns show a characteristic asymmetry with respect to the incidence plane, which is associated with the tilted geometry of the TiO2 columns. The patterns also show the existence of two populations of columns in these GLAD‐TiO2 films. The population of the thinnest columns appears related to the first grown layer and is common for all the films investigated, while the second population of columns grows with the thickness of the films and has been related to wider columns formed by shadowing at the expense of the initially formed columns.
Near‐Infrared Luminescent, Neutral, Cyclic Zn2Ln2 (Ln = Nd, Yb, and Er) Complexes from Asymmetric Salen‐Type Schiff Base Ligands

Published: May 2010

AbstractIn the presence of excess pyridine (py), Zn(OAc)2·2H2O reacted with an equimolar amount of asymmetric salen‐type Schiff base ligand, generated in situ from the condensation of 2,3‐diaminophenol with o‐vanillin or 5‐bromo‐3‐methoxybenzaldehyde, to give the d‐block “complex ligand” [Zn(HL1)(py)] or [Zn(HL2)(py)], respectively. Interaction of [Zn(HL1)(py)] or [Zn(HL2)(py)] with Ln(NO3)3·6H2O in a 1:1 molar ratio gave the cyclic hetero‐tetranuclear complexes [Zn2(L1)2(py)2Ln2(NO3)4(dmf)2]·3Et2O (Ln = Nd, 1; Yb, 2; Er, 3; and Gd, 4) or [Zn2(L2)2Ln2(NO3)4(dmf)4] (Ln = Nd, 5; Yb, 6; Er, 7; and Gd, 8), respectively, in moderate yields. Photophysical studies of these cyclic Zn2Ln2 tetranuclear complexes showed that, upon photoexcitation in the 200–550 nm range corresponding to the intraligand π→π* transition of the Schiff base, strong and characteristic NIR luminescence of Ln3+ ions with emissive lifetimes in the microsecond ranges were observed, whereas the ligand‐centered singlet (1LC) visible fluorescence was mostly quenched as a result of effective intramolecular energy transfer from the 1LC excited state to the Ln3+ ions. In addition, the occupation of py groups at the axial position of Zn2+ ions and the involvement of heavy atoms seem to help to enhance the NIR luminescence to some extent.
Template‐Controlled Formation of an [11]ane‐P2CNHC Macrocyclic Ligand at an Iron(II) Template
Authors: Flores‐Figueroa Aarón , Pape Tania , Weigand Jan J. , Hahn F. Ekkehardt 
Published: May 2010

AbstractComplex [Fe(η5‐C5H5)(η6‐PhMe)]PF6 reacts with 1,2‐bis[bis(2‐fluorophenyl)phosphanyl]benzene (2) in acetonitrile under irradiation for 6 h to give complex [Fe(η5‐C5H5)(2)(CH3CN)]PF6 ([3]PF6). Reaction of [3]PF6 with 1 equiv. of 2‐azidoethyl isocyanide (4) yields complex [Fe(η5‐C5H5)(2)(4)]X ([5]X) (X = Br, PF6). Staudinger reaction with PPh3 at the azido function followed by hydrolysis of the iminophosphorane with HBr yields compound [6]X (X = Br–, PF6 –) with an NH,NH‐stabilized NHC ligand. The facially coordinated NH,NH‐stabilized NHC and the fluorinated diphosphane ligands were linked by N,N′‐deprotonation of the NHC and nucleophilic attack of the nitrogen atoms at two C–F bonds, which gave – after anion exchange with NH4PF6 – complex [1]PF6 bearing the macrocyclic [11]ane‐P2CNHC ligand.

A Novel Family of Onium Salts Based Upon Isonitroso Meldrum's Acid Proves Useful as Peptide Coupling Reagents
Authors: El‐Faham Ayman , Subirós‐Funosas Ramon , Albericio Fernando 
Published: May 2010

AbstractA new family of uronium salts (HTMU, HMMU, and HDmPyMU) based on isonitroso Meldrum's acid (HONM) are reported as stand‐alone coupling reagents. Amide bond formation with the use of these reagents occurred more quickly than that with other uronium salts as a result of the presence of a neighboring group effect with a cyclic structure. Thus, these novel onium salts were often more effective in the acylation of poor nucleophiles and in the control of optical purity than related Oxyma‐ and benzotriazole‐based reagents. Among the HONM derivatives, HMMU showed the best performance in reducing racemization and assembling demanding sequences such as the Aib‐ACP decapeptide or analogues of Leu‐enkephalin pentapeptide. Furthermore, the scope and limitations of the use of HONM as an additive in combination with carbodiimides is discussed.
