The Inorganic Perspective of Nerve Growth Factor: Interactions of Cu2+ and Zn2+ with the N‐Terminus Fragment of Nerve Growth Factor Encompassing the Recognition Domain of the TrkA Receptor

Published: February 2011

AbstractThere is a significant overlap between brain areas with Zn2+ and Cu2+ pathological dys‐homeostasis and those in which the nerve growth factor (NGF) performs its biological role. The protein NGF is necessary for the development and maintenance of the sympathetic and sensory nervous systems. Its flexible N‐terminal region has been shown to be a critical domain for TrkA receptor binding and activation. Computational analyses show that Zn2+ and Cu2+ form pentacoordinate complexes involving both the His4 and His8 residues of the N‐terminal domain of one monomeric unit and the His84 and Asp105 residues of the other monomeric unit of the NGF active dimer. To date, neither experimental data on the coordination features have been reported, nor has one of the hypotheses according to which Zn2+ and Cu2+ may have different binding environments or the Ser1 α‐amino group could be involved in coordination been supported. The peptide fragment, encompassing the 1–14 sequence of the human NGF amino‐terminal domain (NGF(1‐14)), blocked at the C terminus, was synthesised and its Cu2+ and Zn2+ complexes characterized by means of potentiometric and spectroscopic (UV/Vis, CD, NMR, and EPR) techniques. The N‐terminus‐acetylated form of NGF(1‐14) was also investigated to evaluate the involvement of the Ser1 α‐amino group in metal‐ion coordination. Our results demonstrate that the amino group is the first anchoring site for Cu2+ and is involved in Zn2+ coordination at physiological pH. Finally, a synergic proliferative activity of both NGF(1‐14) and the whole protein on SHSY5Y neuroblastoma cell line was found after treatment in the presence of Cu2+. This effect was not observed after treatment with the N‐acetylated peptide fragment, demonstrating a functional involvement of the N‐terminal amino group in metal binding and peptide activity.
Chromium and Molybdenum Pentacarbonyl Complexes of Phosphinocarbodithioates: Synthesis, Molecular Structure and Behaviour in RAFT Polymerisation
Authors: Geagea Roland , Ladeira Sonia , Mazières Stéphane , Destarac Mathias 
Published: February 2011

AbstractMolybdenum and chromium pentacarbonyldiphenylphosphinocarbodithioate complexes have been prepared in a one‐pot reaction from the corresponding metallocarbonyldiphenylphosphine. The complexes have been characterised by IR, 1H, 31P and 13C NMR spectroscopies and by mass spectrometry. The solid‐state structures of [Cr(CO)5{PPh2CS2CH(Ph)CH3}] (1) and [Mo(CO)5{PPh2CS2CH(Ph)CH3}] (2) are reported. Compounds 1 and 2 are isostructural and crystallise in the triclinic P space group. These new organometallic compounds are highly efficient reversible chain‐transfer agents for reversible addition–fragmentation chain‐transfer (RAFT) polymerisation of styrene (St) and n‐butyl acrylate (nBA), with controlled number‐average molar mass values and narrow dispersities (<1.2). The controlled character of the polymerisation was further exemplified by the synthesis of St and nBA diblock copolymers.
Rational Synthesis of Supramolecular Assemblies Based on Tetraplatinum Units: Synthesis, Characterization, and Selective Substitution Reactions of Four Different Pt4 Clusters

Published: February 2011

AbstractFour different types of square‐planar Pt4 clusters, trans‐[Pt4(μ‐OCOCH3)6(μ‐ArNCHNAr)2] (2: ArNCHNAr=N,N′‐diarylformamidinate), [Pt4(μ‐OCOCH3)7(μ‐ArNCHNAr)] (8), cis‐[Pt4(μ‐OCOCH3)6(κ4‐N4‐DArBp)] (9: DArBp=1,3‐bis(arylbenzamidinate)propane), and [Pt4Cl2(μ‐OCOCH3)5(κ4‐N2,P2‐dpfam)] (13: dpfam=N,N′‐bis[(2‐diphenylphosphino)phenyl]formamidinate), were successfully prepared by using selective substitution reactions of in‐plane acetate ligands of [Pt4(μ‐OCOCH3)8] (1), which has four in‐plane and four out‐plane acetate ligands, with appropriate capping ligands. Fundamental substitution reactions of the remaining in‐plane acetates with benzoic acid derivatives were also investigated. All newly prepared complexes were characterized from spectral and physical data and combustion analysis. X‐ray crystallographic studies of some of the clusters were also performed. Electrochemical measurements of amidinate‐modified Pt4 clusters revealed stepwise oxidation processes of the Pt4 core due to Pt49+/Pt48+ and Pt410+/Pt49+. Based on the lability of the in‐plane acetate ligands of the modified Pt4 clusters, reactions of cis‐[Pt4(μ‐OCOCH3)6(κ4‐N4‐DArBp)] (9 c: Ar=C6H4tBu‐4) with ferrocenedicarboxylic acid and p‐phenylenedipropionic acid resulted in the selective formation of cyclic dimers 17 and 18 and the reaction of 13 with 4,4′‐biphenyldicarboxylic acid afforded a linear dimer 20. The dimers were characterized by spectral data, as well as X‐ray analyses for 17 and 18. The finding of two Fe3+/Fe2+ redox couples in the electrochemical measurement of dimer 17 indicated that two ferrocenyl units in dimer 17 communicated electronically.
Complete Stereocontrol in Organocatalytic Additions of β‐Ketosulfoxides to Conjugated Aldehydes
Authors: García Ruano José Luis , Alvarado Cuauhtémoc , Díaz‐Tendero Sergio , Alemán José 
Published: February 2011

AbstractThe use of β‐ketosulfoxides as nucleophiles in reactions with α,β‐unsaturated aldehydes catalyzed by proline derivatives allows complete control of configuration at the two chiral centers that are created during 1,4‐addition reactions. The sulfinyl group can be used to create additional chiral centers in the resulting compounds and then removed while preserving the chirality of the carbon joined to the sulfur. The catalyst and the sulfinyl group are mainly responsible for the configurational control of the carbon atoms acting as electrophile and nucleophile, respectively, which allows the preparation of the four possible diastereoisomers in optically pure form. Theoretical calculations of the possible chiral nucleophilic species bearing diastereotopic faces allow us to postulate, for the first time, that enolates, instead of enols, are the active reagents in these reactions.
New Highly Stable Metallabenzenes via Nucleophilic Aromatic Substitution Reaction

Published: February 2011

AbstractTreatment of the ruthenabenzene [Ru{CHC(PPh3)CHC(PPh3)CH}Cl2(PPh3)2]Cl (1) with excess 8‐hydroxyquinoline in the presence of CH3COONa under air atmosphere produced the SNAr product [(C9H6NO)Ru{CHC(PPh3)CHC(PPh3)C}(C9H6NO)(PPh3)]Cl2 (3). Ruthenabenzene 3 could be stable in the solution of weak alkali or weak acid. However, reaction of 3 with NaOH afforded a 7:1 mixture of ruthenabenzenes [(C9H6NO)Ru{CHC(PPh3)CHCHC}(C9H6NO)(PPh3)]Cl (4) and [(C9H6NO)Ru{CHCHCHC(PPh3)C}(C9H6NO)(PPh3)]Cl (5), presumably involving a PC bond cleavage of the metallacycle. Complex 3 was also reactive to HCl, which results in a transformation of 3 to ruthenabenzene [Ru{CHC(PPh3)CHC(PPh3)C}Cl2(C9H6NO)(PPh3)]Cl (6) in high yield. Thermal stability tests showed that ruthenabenzenes 4, 5, and 6 have remarkable thermal stability both in solid state and in solution under air atmosphere. Ruthenabenzenes 4 and 5 were found to be fluorescent in common solvents and have spectral behaviors comparable to those organic multicyclic compounds containing large π‐extended systems.
Enantiopure, Monodisperse Alleno‐acetylenic Cyclooligomers: Effect of Symmetry and Conformational Flexibility on the Chiroptical Properties of Carbon‐Rich Compounds

Published: February 2011

AbstractA series of enantiopure, monodisperse alleno‐acetylenic cyclooligomers were synthesized. The single‐crystal X‐ray structures of the cyclic trimer and hexamer were resolved, providing insights into the symmetry of these molecules. Electronic circular dichroism (ECD), optical rotatory dispersion (ORD), Raman spectroscopy, and vibrational circular dichroism (VCD) data were analyzed with the aid of theoretical calculations. This multidimensional approach ultimately provided general guidelines that are useful for designing carbon‐rich compounds with intense chiroptical properties.
