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.

Structure-based design, synthesis, biological evaluation, and molecular docking of novel 10-methoxy dibenzo[b,h][1,6]naphthyridinecarboxamides

10-methoxy dibenzo[b,h][1,6]naphthyridine carboxylic acid was successfully synthesized from 3-methoxyaniline by a new route. By utilizing a structure-based epharmacophore developed from the active site of 3-phosphoinositide-dependent kinase-1, a series of nine novel 10-methoxy dibenzo[b,h][1,6]naphthyridinecarboxamides was synthesized and characterized by different spectral techniques. Three of them are found to be active by screening against A549 cell line and showed significant anticancer activity when compared to a marketed lung cancer drug, pemetrexed. The molecular docking and in silico pharmacokinetic predictions provide detailed understanding for utilizing the dibenzo[b,h][1,6]naphthyridine scaffold in future drug discovery and development of PDK1 inhibitors.

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.

Structure-Guided Optimization of HIV Integrase Strand Transfer Inhibitors

Integrase mutations can reduce the effectiveness of the first-generation FDA-approved integrase strand transfer inhibitors (INSTIs), raltegravir (RAL) and elvitegravir (EVG). The second-generation agent, dolutegravir (DTG), has enjoyed considerable clinical success; however, resistance causing mutations that diminish the efficacy of DTG have appeared. Our current findings support and extend the substrate envelope concept that broadly effective INSTIs can be designed by filling the envelope defined by the DNA substrates. Previously, we explored 1-hydroxy-2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxamides as an INSTI scaffold, making a limited set of derivatives, and concluded that broadly effective INSTIs can be developed using this scaffold. Herein, we report an extended investigation of 6-substituents as well the first examples of 7-substituted analogues of this scaffold. While 7-substituents are not well-tolerated, we have identified novel substituents at the 6-position that are highly effective, with the best compound (6p) retaining better efficacy against a broad panel of known INSTI resistant mutants than any analogues we have previously described.

Palladium complexes with an annellated mesoionic carbene (MIC) ligand: catalytic sequential Sonogashira coupling/cyclization reaction for one-pot synthesis of benzofuran, indole, isocoumarin and isoquinolone derivatives

Two Pd(II) complexes (1 and 2) featuring a fused pi-conjugated imidazo[1,2-a][1,8]naphthyridine-based mesoionic carbene ligand have been synthesized and structurally characterized. Both complexes effectively catalyze the one-pot synthesis of benzofuran starting from phenylacetylene and 2-iodophenol under mild conditions. Complex 1 is found to be an excellent catalyst for the straightforward access to a library of benzofuran, indole, isocoumarin and isoquinolone derivatives by the reaction of terminal alkynes with 2-iodo derivates of phenol, N-methyl aniline, benzoic acid and N-methyl benzamide, respectively. The general utility of the catalytic method is demonstrated using a variety of diversely substituted terminal alkynes and the corresponding desired products are obtained in good to excellent yields. On the basis of control experiments, a two-cycle mechanism is proposed which involves the Sonogashira coupling of 2-iodo derivatives with alkynes and the subsequent cyclization of the corresponding 2-alkynyl compounds.
