Histone modifications proposed to regulate sexual differentiation of brain and behavior
Authors: Gagnidze Khatuna , Weil Zachary M. , Pfaff Donald W. 
Published: September 2010

AbstractExpression of sexually dimorphic behaviors critical for reproduction depends on the organizational actions of steroid hormones on the developing brain. We offer the new hypothesis that transcriptional activities in brain regions executing these sexually dimorphic behaviors are modulated by estrogen‐induced modifications of histone proteins. Specifically, in preoptic nerve cells responsible for facilitating male sexual behavior in rodents, gene expression is fostered by increased histone acetylation and reduced methylation (Me), and, that the opposite set of histone modifications will be found in females. Conversely, in ventromedial hypothalamic neurons that are responsible for coordinating female sexual behavior, transcriptional activities in genetic females are fostered by increased histone acetylation and reduced Me, and, further, that the opposite set of histone modifications will be found in males. Thus, these epigenetic events will guarantee that effects of sex hormone exposure during the neonatal critical period will be translated into lasting sex differences in adult reproductive behaviors.

Published: September 2010

AbstractThe kinetics of the reactions of 1,2‐diaza‐1,3‐dienes 1 with acceptor‐substituted carbanions 2 have been studied at 20 °C. The reactions follow a second‐order rate law, and can be described by the linear free energy relationship log k(20 °C)=s(N+E) [Eq. (1)]. With Equation (1) and the known nucleophile‐specific parameters N and s for the carbanions, the electrophilicity parameters E of the 1,2‐diaza‐1,3‐dienes 1 were determined. With E parameters in the range of −13.3 to −15.4, the electrophilic reactivities of 1 a–d are comparable to those of benzylidenemalononitriles, 2‐benzylideneindan‐1,3‐diones, and benzylidenebarbituric acids. The experimental second‐order rate constants for the reactions of 1 a–d with amines 3 and triarylphosphines 4 agreed with those calculated from E, N, and s, indicating the applicability of the linear free energy relationship [Eq. (1)] for predicting potential nucleophilic reaction partners of 1,2‐diaza‐1,3‐dienes 1. Enamines 5 react up to 102 to 103 times faster with compounds 1 than predicted by Equation (1), indicating a change of mechanism, which becomes obvious in the reactions of 1 with enol ethers.
Late‐Transition‐Metal Complexes as Tunable Lewis Bases
Authors: Bauer Jürgen , Braunschweig Holger , Brenner Peter , Kraft Katharina , Radacki Krzysztof , Schwab Katrin 
Published: September 2010

AbstractSyntheses of the first heteroleptic N‐heterocyclic carbene (NHC)–phosphane platinum(0) complexes and formation of the corresponding Lewis acid–base adducts with aluminum chloride is reported. The influence of N‐heterocyclic carbenes on tuning the Lewis basic properties of the metal complexes was judged from spectroscopic, structural, and computational data. Conclusive experimental evidence for the enhanced Lewis basicity of NHC‐containing complexes was provided by a transfer reaction.
New Insights into Factors Influencing BN Bonding in X:BH3−nFnand X:BH3−nClnfor X=N2, HCN, LiCN, H2CNH, NF3, NH3andn=0–3: The Importance of Deformation
Authors: Alkorta Ibon , Elguero José , Del Bene Janet E. , Mó Otilia , Yáñez Manuel 
Published: September 2010

AbstractUnderstanding the bonding in complexes X:BH3−nFnand X:BH3−nCln, for X=N2, HCN, LiCN, H2CNH, NF3, NH3withn=0–3, is a challenging task. The trends in calculated binding energies cannot be explained in terms of any of the usual indexes, including π donation from the halogen lone pairs to the p(π) empty orbital on B, deformation energies, charge capacities, or LUMO energies, which are normally invoked to explain the higher Lewis acidity of BCl3relative to BF3. The results of the high‐level G3B3 ab initio calculations reported in this study suggest that the interaction energies of these complexes are determined by a combination of at least three factors. These include the decrease in the electron‐accepting ability of B as a result of π donation by the halogen atom, the increase in the electron‐acceptor capacity of B due to deformation of the acid, and the large increase in the deformation energy of the acid with increasing halogen substitution. The dominant effects are those derived from the electronic effects of acid deformation. Deformation not only has direct energetic consequences, which are reflected in the large differences between dissociation (D0) and interaction (Eint) energies, but also leads to an enhancement of the intrinsic acidities of BH3−nFnand BH3−nClnmoieties by lowering the LUMO energies to very different extents, consistent with the frontier orbital model of chemical reactivity. Although this lowering depends on both the number and the nature of the halogen substituents, binding energies do not systematically increase or decrease as the number of halogen atoms increases.
Fullerene–Coumarin Dyad as a Selective Metal Receptor: Synthesis, Photophysical Properties, Electrochemistry and Ion Binding Studies

Published: September 2010

AbstractA coumarin derivative with a malonate unit has been synthesized and used for the preparation of a fullerene–coumarin dyad through the Bingel cyclopropanation method. The newly synthesized dyad is soluble in organic solvents and has been fully characterized with traditional spectroscopic techniques. Electronic interactions between the two components of the dyad were probed with the aid of UV/Vis spectroscopy, fluorescence emission, and electrochemistry measurements. Our studies clearly show the presence of electronic interactions between C60 and modified coumarin in the ground state; efficient electron‐transfer quenching of the singlet excited state of the coumarin moiety by the appended fullerene sphere was also observed. Time‐resolved fluorescence measurements revealed lifetimes for the coumarin–C60 dyad at a maximum of 50 ps, while the quantum yield was reaching unity. Additionally, the redox potentials of the C60–coumarin dyad were determined and the energetics of the electron‐transfer processes were evaluated. Finally, after alkaline treatment of C60–coumarin, which resulted in the deprotection of carboxylate units, the dyad was tested as a metal receptor for divalent metal cations; ion competition studies and fluorescence experiments showed binding selectivity for lead ions.
