Linear hexanuclear nickel complexes with rich electrochemical features and facility to reduction

Two novel linear hexanuclear nickel complexes [Ni-6(mu(6)-dpznda)(4)Cl-2](PF6)(2) (1) and [[Ni-6(mu(6)-dpznda)(4)(NCS)(2)](PF6)(2) (2) (H(2)dpznda = N-2,N-7-di(pyrazin-2-yl)-1,8-naphthyridine-2,7-diamine) were synthesized and structurally characterized. Both the two complexes consist of a linear metal chain and four supporting ligands which are helically wrapped around the metal core. The single crystal X-ray structural analysis showed that the complex 1 belonged to rhombohedral system, space group R-3 with a = b = 34.2051(8),c = 20.7751(5) angstrom, V = 21050.2(9) angstrom(3) and Z = 9. Direct-current magnetic susceptibility measurements showed weak antiferromagnetic interactions with coupling parameters of g = 2.04 and J = -8.27 cm(-1) for 1 and g = 2.02 and J = -12.62 cm(-1) for 2, respectively ( = -J (S) over cap (1)(S) over cap (2), S1 = S2 = 1). The decrease of magnetic moments at low temperature was partly attributed to ZFS. The electrochemical study on complex 1 shows rich features and facility to reduction in its cyclic voltammogram by displaying four reversible redox couples at E-1/2 = +0.01,-0.29,-0.64 and -0.73 V (vs. Ag/AgCl).

Mutations in human immunodeficiency virus type 1 integrase confer resistance to the naphthyridine L-870,810 and cross-resistance to the clinical trial drug GS-9137

To gain further insight into the understanding of the antiviral resistance patterns and mechanisms of the integrase strand transfer inhibitor L-870,810, the prototypical naphthyridine analogue, we passaged the human immunodeficiency virus type 1 strain HIV-1(IIIB) in cell culture in the presence of increasing concentrations of L-870,810 (IIIB/L-870,810). The mutations L74M, E92Q, and S230N were successively selected in the integrase. The L74M and E92Q mutations have both been associated in the past with resistance against the diketo acid (DKA) analogues L-708,906 and S-1360 and the clinical trial drugs MK-0518 and GS-9137. After 20, 40, and 60 passages in the presence of L-870,810, IIIB/L-870,810 displayed 22-, 34-, and 110-fold reduced susceptibility to L-870,810, respectively. Phenotypic cross-resistance against the DKA analogue CHI-1043 and MK-0518 was modest but that against GS-9137 was pronounced. Recombination of the mutant integrase genes into the wild-type background reproduced the resistance profile of the resistant IIIB/L-870,810 strains. In addition, resistance against L-870,810 was accompanied by reduced viral replication kinetics and reduced enzymatic activity of integrase. In conclusion, the accumulation of L74M, E92Q, and S230N mutations in the integrase causes resistance to the naphthyridine L-870,810 and cross-resistance to GS-9137. These data may have implications for cross-resistance of different integrase inhibitors in the clinic.

Mononuclear gold(iii) complexes with diazanaphthalenes: the influence of the position of nitrogen atoms in the aromatic rings on the complex crystalline properties

A series of mononuclear gold(iii) complexes of the general formula [AuCl3(diazanaphthalene)], where diazanaphthalene is quinazoline (qz, 1), phthalazine (phtz, 2), 1,5-naphthyridine (1,5-naph, 3), 1,6-naphthyridine (1,6-naph, 4) or 1,8-naphthyridine (1,8-naph, 5), were prepared and fully characterized. The complexes 1-5 consist of discrete monomeric species with the Au(iii) cation in a square planar coordination geometry surrounded by three chloride anions and one diazanaphthalene ligand. Crystallographic studies indicate the presence of an extended 4 + 1 or 4 + 2 geometry around the square planar [AuCl3(diazanaphthalene)] center due to AuMIDLINE HORIZONTAL ELLIPSISCl and AuMIDLINE HORIZONTAL ELLIPSISN interactions. The crystal structures of these complexes are controlled by a variety of intermolecular interactions that utilize the amphiphilic properties of the coordinated chloride anions and involve C-H groups, pi-electrons, and an uncoordinated nitrogen atom of the diazanaphthalene ligand. The usual offset pi-stacking between the N-heteroaromatic ligands appears to be completely hindered between the 1,5-naph fragments and significantly weakened between the 1,6-naph and 1,8-naph in their respective complexes 3, 4 and 5, for which the average molecular polarizability (alpha) values are the lowest in the series. It is remarkable that the [AuCl3(benzodiazine)] complexes 1 and 2 form centrosymmetric crystals, but the [AuCl3(naphthyridine)] complexes 3-5 assemble into non-centrosymmetric aggregates, making them potential alternatives to the previously studied systems for application in various fields by taking advantage of their polarity.

Reversible Intramolecular Cyclization in Ruthenium Complexes Induced by Ligand-centered One-electron Transfer on Bidentate Naphthyridine: An Important Intermediate for Both Metal- and Organo-Hydride Species

Two types of dicarbonykuthenium(II) complexes bearing the unsymmetrical bidentate ligand 2-(2-pyridy1)-1,8-naphthyridine were prepared. The complexes undergo irreversible ligand-localized one-electron reduction to form redox-induced metal-lacyclization between the bidentate naphthyridyl ligand and the terminal CO ligand located nearby. Chemical reductions using NaBH4 were also performed to isolate the reaction products; the formation of both a metal hydride (Ru-H) and an organo hydride (C-H) species was confirmed.

Naphthyridine-based emitters simultaneously exhibiting thermally activated delayed fluorescence and aggregation-induced emission for highly efficient non-doped fluorescent OLEDs

Luminescent materials simultaneously exhibiting superior luminescence efficiency, thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) properties in the solid state are eagerly required for highly efficient non-doped organic light-emitting diodes (OLEDs). Herein, two new emitters, namely ND-AC and CND-AC, featuring a naphthyridine or cyano-naphthyridine segment as the electron acceptor and an acridine unit as the electron donor were designed, synthesized and investigated. The nearly orthogonal molecular configuration of the target emitters not only endows them with small energy differences between singlet and triplet states for ensuring TADF character but also affords a remarkable AIE feature. Due to the high photoluminescence quantum yields, and excellent TADF and AIE characteristics, the doped and non-doped OLEDs based on ND-AC exhibit outstanding performances with maximum external quantum efficiencies of 16.8% and 12.0%, respectively. These results demonstrate that the naphthyridine-based emitters have a promising application in OLEDs.

Asymmetric Synthesis of a 5,6,7,8-Tetrahydro-1,6-naphthyridine Scaffold Leading to Potent Retinoid-Related Orphan Receptor gamma t Inverse Agonist TAK-828F

An asymmetric synthesis of the tetrahydronaphthyridine scaffold of TAIL-828F as a ROR gamma t inverse agonist has been developed. The synthesis features a newly discovered atom-economical protocol for Heck-type vinylation of chloropyridine using ethylene gas, an unprecedented formation of dihydronaphthyridine directly from 2-vinyl-3-acylpyridine mediated by ammonia, and a ruthenium-catalyzed enantioselective transfer hydrogenation as key steps. This represents the first example of the enantioselective synthesis of a 5,6,7,8-tetrahydro-1,6-naphthyridine compound. The new synthesis is also free of chromatography or distillation purification processes and therefore qualifies for extension to large-scale manufacture.

A displacement assay was carried out in a DMSO-water mixture with the addition of various anions to the solutions of the complexes, and it was observed that these systems have a high capacity to selectively detect cyanide.
