[mu-Bis(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene]bis[difluoridoboron(III)]

In the title compound, C(20)H(18)B(2)F(4)N(6), the bis(5,7-dimethyl-1,8-naphthyridin-2-yl) diazene molecule is bisected by a symmetry centre midway between the central N atoms of the diazene group. Each of the symmetry-related halves of the molecule binds to a B atom through an N,N’-bite. Two terminal F ions complete the distorted BN(2)F(2) tetrahedral geometry around each B atom. The BF(2) plane is almost perpendicular to the boron-naphthyridine ring plane, with a dihedral angle of 87.8 (2)degrees. The main interactions in the crystal structure are some C-H center dot center dot center dot F hydrogen bonds and pi-pi contacts between 1,8-naphthyridine rings [centroid-centroid distance = 4.005 (1) angstrom].

Biologic-like In Vivo Efficacy with Small Molecule Inhibitors of TNF alpha Identified Using Scaffold Hopping and Structure-Based Drug Design Approaches

Scaffold hopping and structure-based drug design were employed to identify substituted 4-aminoquinolines and 4-aminonaphthyridines as potent, small molecule inhibitors of tumor necrosis factor alpha (TNF alpha). Structure-activity relationships in both the quinoline and naphthyridine series leading to the identification of compound 42 with excellent potency and pharmacokinetic profile are discussed. X-ray co-crystal structure analysis and ultracentrifugation experiments clearly demonstrate that these inhibitors distort the TNF alpha trimer upon binding, leading to aberrant signaling when the trimer binds to TNF receptor 1 (TNFR1). Pharmacokinetic-pharmacodynamic activity of compound 42 in a TNF-induced IL-6 mouse model and in vivo activity in a collagen antibody-induced arthritis model, where it showed biologic-like in vivo efficacy, will be discussed.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2835-95-2 help many people in the next few years. COA of Formula: C7H9NO.

DFT calculations of the tautomerization and NW properties of 5-amino-7-(pyrrolidin-1-y1)-2,4,4-trimethy1-1,4-dihydro-1,6-naphthyridine-8-carbonitrile (APNC)

Amine-imine tautomerization in 5-amino-7-(pyrrolidin-1-y1)-2,4,4-trimethy1-1,4-dihydro-1,6-naphthyridine-8-carbonitrile (APNC) has been studied using the B3LYP, CAM-B3LYP and wB97XD with 6-311++G(d,p) basis set. Optimum molecular geometries, electronic properties, energetics and electronic densities of these systems have been discussed and compared with the available experimental data. Investigation reveals that one tautomer (the amine tautomer) dominates the gas phase. The photochromic properties of APNC and its two imine tautomers have been studied at the elected DFT-functionals and basis set. The interconversion Al to 12/13 is predicted to occur photochemically. The NLO properties were also evaluated and discussed. (C) 2017 Elsevier B.V. All rights reserved.

Photocatalytic H-2 production by dirhodium(ii,ii) photosensitizers with red light

Photocatalytic proton reduction to generate H-2 was achieved with the photosensitizers Rh-2(DTolF)(2)(npCOO)(2) (DTolF = p-ditolylformamidinate; npCOO(-) = 2-carboxylate-1,8-naphthyridine; 1) and [Rh-2(DTolF)(2)(qnnp)(2)][BF4](2) (qnnp = 2-(quinolin-2-yl)-1,8-naphthyridine; 2) using a relay system containing the sacrificial donor BNAH (1-benzyl-1,4-dihydronicotinamide), electron acceptor MV2+ (methylviologen), and Pt nanoparticles as the catalyst with 655 nm irradiation. Comparison of the H-2 evolution under similar experimental conditions show comparable activity of the Rh-2(ii,ii) complexes ((irr) = 655 nm) to that of the prototypical [Ru(bpy)(3)](2+) (bpy = 2,2-bipyridine; 3) with (irr) = 447 nm. This work demonstrates the ability of the new panchromatic Rh-2(ii,ii) complexes to achieve photocatalysis with red light.

A Copper-Catalyzed Cascade Approach for the Synthesis of Dibenzo[b,f]1,8-naphthyridine Derivatives

The synthesis of some dibenzo[b,f]-[1,8]naphthyridine derivatives in a cascade manner is reported. The reaction includes a Knovenagel condensation, the insertion of a nitrile and an alkyne into an N-H bond and an oxidation/oxidative C-C bond cleavage sequence in the presence of copper iodide. The key 1,8-naphthyridine core was constructed in a cascade manner during the course of the reaction itself which allows diverse dibenzo[b,f]-[1,8]naphthyridine derivatives to be readily prepared.

The effect of reduction on rhenium(I) complexes with binaphthyridine and biquinoline ligands: A spectroscopic and computational study

A number of rhenium complexes with binaphthyridine and biquinoline ligands have been synthesized and studied. These are [Re(L)(CO)(3)Cl] where L = 3,3′-dimethylene-2,2′-bi-1,8-naphthyridine (dbn), 2,2′-bi-1,8-naphthyridine (bn), 3,3′-dimethylene-2,2′-biquinoline (dbq), and 3,3′-dimethyl-2,2′-biquinoline (diq). This series represents ligands in which the electronic properties and steric preferences are tuned. These complexes are modeled using density functional theory (DFT). An analysis of the resonance Raman spectra for these complexes, in concert with the vibrational assignments, reveals that the accepting molecular orbital (MO) in the metal-to-ligand charge transfer (MLCT) transition is the LUMO and causes bonding changes at the interring section of the ligand. The electronic absorption spectroelectrochemistry for the reduced complexes of [Re(dbn)(CO)(3)Cl], [Re(dbq)(CO)(3)Cl], and [Re(diq)(CO)(3)Cl] suggest that the singly occupied MO is delocalized over the entire ligand structure despite the nonplanar nature of the diq ligand in [Re(diq)(CO)(3)Cl]. The IR spectroelectrochemistry for [Re(dbn)(CO)(3)Cl], [Re(dbq)(CO)(3)Cl], and [Re(bn)(CO)(3)Cl] reveal that reduction lowers the CO ligand vibrational frequencies to a similar extent in all three complexes. The substitution of naphthyridine for quinoline has little effect on the nature of the singly occupied MO. These data are supported by DFT calculations on the reduced complexes, which reveal that the ligands are flattened out by reduction: This may explain the similarity in the properties of the reduced complexes.
