The syntheses and crystal structures of N-(7-bromomethyl-1, 8-naphthyridin-2- yl)acetamide dioxane hemisolvate, C11H10BrN3?0.5C4H8O2, (I), and bis[N-(7- dibromomethyl-1, 8-naphthyridin-2-yl)acetamide] dioxane hemisolvate, 2C11H9Br2N3?0.5C4H8O2, (II), are described. The molecules adopt a conformation with the N-H hydrogen pointing towards the lone electron pair of the adjacent naphthyridine N atom. The crystals of (I) are stabilized by a three-dimensional supramolecular network comprising N-H?N, C-H?N and C-H?O hydrogen bonds, as well as C-Br?pi halogen bonds. The crystals of compound (II) are stabilized by a three-dimensional supramolecular network comprising N-H?N, C-H?N and C-H?O hydrogen bonds, as well as C-H?pi contacts and C-Br?pi halogen bonds. The structure of the substituent attached in the 7-position of the naphthyridine skeleton has a fundamental influence on the pattern of intermolecular noncovalent bonding. While the Br atom of (I) participates in weak C-Br?Oguest and C-Br?picontacts, the Br atoms of compound (II) are involved in host-host interactions via C-Br?O C, C-Br?N and C-Br?pi bonding.

Boronic acid is known to form DD¡¤AA, DA¡¤AD, and AA¡¤DD type complexes. In this article, the ability of phenyldiboronic acid to associate with hydrogen bond acceptors (1,8-naphthyridine, 5,6,11,12-tetraazanaphthacene, 2,8a-dihydropyrano[2,3-b]pyran and 4aH-[1,4]dioxino[2,3-b][1,4]dioxine) has been analyzed in light of density functional theory. Stabilization energy and thermochemical analysis predict the feasibility of formation of DD¡¤AA type complexes between phenyldiboronic acid and N-/O-hydrogen bond acceptors. The gas and solvent phase calculations showed that the stabilization energy varies with the size of the association geometry. IR and NMR studies revealed the weakening of the O-H bond during complexation. Complexes with as many as three boronic acids and four hydrogen bond acceptors are studied and are predicted to be stable.

Liquid-liquid extraction is the major technique being applied for the partitioning of f-elements from nuclear waste. In this review, the recent developments in ligand design, optimization and extraction properties are summarised for the main classes of extractants (organophosphorus ligands, diamides and N-heterocycles), with a focus on the separation of actinides and lanthanides. Structural modifications, pre-organisation and different solvent systems, as key factors for the fine-tuning of the extraction properties, are discussed. From this review, it appears that small modifications of the structure of the ligand, the pre-organising platform or the solvent can have significant impact on the extraction (and separation) of metal ions. Interest in the combinations of ligands for the extraction processes is growing, since they provide improvements over individual ligands. Similarly, unconventional approaches are being pursued to develop more efficient and greener processes.

Nucleobase recognition in water is successfully achieved by the use of an abasic site (AP site) as the molecular recognition field. We intentionally construct the AP site in DNA duplex so as to orient the AP site toward a target nucleobase and examine the complexation of 2-amino-7-methylnaphthyridine (AMND) with nucleobases at the AP site. AMND is found to selectively bind to cytosine (C) base with a 1:1 binding constant of >106 M-1, accompanied by remarkable quenching of its fluorescence. In addition to hydrogen bonding, a stacking interaction with nucleobases flanking the AP site seems responsible for the binding properties of AMND at the AP site. Possible use of AMND is also presented for selective and visible detection of a single-base alternation related to the cytosine base. Copyright

We report the bonding strength of nickel ions in trinickel extended metal atom chains (EMACs) and dinickel complexes using Raman, surface-enhanced Raman scattering (SERS), and electrochemical SERS (ECSERS). By using the redox ability of gold and silver nanoparticles during plasmonic excitation, the bonding strength and the valence state of metal ions can be determined. For dinickel complexes, we assign the Raman band at 322 cm-1 to Ni2+-Ni3+ stretch in [Ni2(TPG)4]BF4 (TPG = N,N?,N?-triphenylguanidinate, [Ni2]5+) and 327 cm-1 for Ni2+-Ni1+ stretch of [Ni2]3+ moieties in Ni5(camnpda)4. For trinickel EMACs, no band is assigned to Ni3 symmetric stretch nuNi3 sym in the neutral form Ni3(dpa)4X2 (dpa = dipyridyl amido and X = NCS, Cl). In the reduced form, the ECSERS curves show the band at 242 cm-1, which also appeared at gold nanoparticle SERS measurement, assigned to nuNi3 sym for [Ni3]5+ core. The trinickel complexes were reduced by gold nanosphere, and this nuNi3 sym band is further enhanced with SERS measurements when gold nanorods were used and the trinickel EMACs served as bridging compounds on both ends. On increasing the applied voltage in ECSERS to +1.3 V, complexes were oxidized and one additional band at 351 cm-1 appeared. This new band is assigned to nuNi3 sym of [Ni3]7+ in [Ni3(dpa)4X2]+. Great vibrational frequency indicates that one electron from the metal sigma? orbital instead of ligand was removed, leading to a three metal center bond. Distinct from the vibrational band wavenumber obtained in dinickel complexes, we confirm that [Ni3]5+,7+ has delocalized electronic structures.

Phosphodiesterase 10A (PDE10A) is a double substrate enzyme that hydrolyzes second messenger molecules such as cyclic-3′,5′-adenosine monophosphate (cAMP) and cyclic-3′,5′-guanosine monophosphate (cGMP). Through this process, PDE10A controls intracellular signaling pathways in the mammalian brain and peripheral tissues. Pharmacological, biochemical, and anatomical data suggest that disorders in the second messenger system mediated by PDE10A may contribute to impairments in the central nervous system (CNS) function, including cognitive deficits as well as disturbances of behavior, emotion processing, and movement. This review provides a detailed description of PDE10A and the recent advances in the design of selective PDE10A inhibitors. The results of preclinical studies regarding the potential utility of PDE10A inhibitors for the treatment of CNS-related disorders, such as schizophrenia as well as Huntington?s and Parkinson?s diseases are also summarized.

During the last decade there has been increased interest in the development of homogeneous catalytic systems to promote homo- or copolymerization reactions of unsaturated hydrocarbons. This review is focused on systems based on palladium complexes with nitrogen-donor ligands and on their application as catalysts (or precatalysts) for co- and terpolymerization of carbon monoxide and olefins. Detailed catalytic performance is reported (productivity, molecular weight values and stereoregularity of the copolymers) allowing comparison between different systems. Particular attention will be addressed to the relationship between catalyst structure and structural features of the polymers synthesized. A comment on the mechanism involved in the various reactions is also given.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C8H6N2, you can also check out more blogs about254-60-4

The electrostatic nature of the hydrogen bond makes it straightforward, in principle, to electrochemically perturb the strength of hydrogen bonds by using oxidation to create stronger H-donors or reduction to create stronger H-acceptors. However, oxidation or reduction can also lead to proton transfer and subsequent electron transfer, which can nullify the effect of the initial electron transfer. Illustrative examples of these complications based on a series of investigations of electroactive, urea-containing 2 H-bond dimers are described. It is also shown that proton transfer accompanying electron transfer can be used to advantage with two examples of oxidative dissociation of 4 H-bond dimers that are of interest for the construction of supramolecular polymers and gels. In both cases proton transfer is key to achieving the desired outcome. Moving forward, it is argued that proton transfer should always be considered as a possible useful component in the design of electrochemically controllable H-bonding systems.
