New research progress on 23814-12-2 in 2021. 23814-12-2, Name is 1H-Benzo[d][1,2,3]triazole-5-carboxylic acid, molecular formula is C7H5N3O2, Category: naphthyridines, SMILES is O=C(C1=CC=C(NN=N2)C2=C1)O belongs to naphthyridine compound, is a common compound. In a patnet, author is Andrews, Michael, once mentioned the new application about 23814-12-2.

2,7-Dimethyl-1,8-naphthyridine (L-1) reacts with pentacarbonylchlororhenium in toluene or chloroform to give the target complex fac-{ReCl(CO)(3)(L-1)}. X-ray crystallographic data were obtained for fac-{ReCl(CO)(3)(L-1)}. The structural and H-1 NMR data suggest that the ligand coordinates to the rhenium in a bidentate fashion in both solid and solution states. The complex was also found to be luminescent in both solution and solid states. The fluxionality of the ligand in solution causes ligand-centred emission to be observed in solution, whereas only (MLCT)-M-3 emission was observed in the solid state. Although the complex was air-stable, the lability of L-1 was studied in H-1 NMR experiments where CD3OD induced complete ligand dissociation over the course of 24 h, and also in reaction of fac-{ReCl(CO)(3)(L-1)} with one equivalent of 2,2′-bipyridine in chloroform which resulted in quantitative ligand exchange.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 23814-12-2. Category: naphthyridines.

Chemical Research Letters, April 2021. Application of 63503-60-6, In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. 63503-60-6, Name is 3-Chlorophenylboronic acid, SMILES is ClC1=CC=CC(=C1)B(O)O, belongs to naphthyridine compound. In a article, author is Mahalakshmi, G., introduce new discover of the category.

Two new 10-methoxydibenzo[b,h][1,6]naphthyridine-2-carboxamide derivatives (R1 and R2) have been synthesized and characterized using different spectral techniques. The binding of these probes with DNA was investigated using spectral (Electronic, fluorescence, H-1 NMR and circular dichroism) and molecular docking studies. These probes exhibited a strong fluorescence around 440 nm upon excitation around 380 nm. Electronic and competitive fluorescence titration studies, in HEPES [(4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid)] buffer/dimethyl sulfoxide (pH 7.4) medium, suggest that these probes bind strongly to DNA, which is substantiated by H-1 NMR study. The binding constants are calculated to be 5.3 x 10(7) and 6.8 x 10(6) M–(1) for R1 and R2, respectively. From the results of spectral studies, it is proposed that the mechanism of binding of these probes with DNA is through minor groove binding mode, which is further confirmed by circular dichroism and molecular docking studies. Initial cell viability screening using MTT (3-[4,5-methylthiazol-2-yl]-2,5-diphenyl-tetrazolium bromide) assay shows that normal Vero cells are viable towards these probes at nano molar concentration, which is the concentration range employed in the present study for DNA staining (IC50 in the order of 0.023 mM). The enhancement in fluorescence intensity of these probes upon binding with DNA enables the staining of DNA in agarose gel in gel electrophoresis experiment. The sensitivity of these probes is comparable with that of ethidium bromide and DNA amounts as low as 4 nano gram are detectable. Communicated by Ramaswamy H. Sarma

HIV-1 integrase is an extremely important nominee in developing new and effective drugs especially naphthyridine compounds against acquired immune deficiency syndrome. The quantitative structure-activity relationship (QSAR) modeling is the most powerful method in computer-aided drug design and will be used to help the design of new naphthyridine derivatives. Different computational 2D-QSAR procedures applied to predict the relationship between the computational descriptors of naphthyridine derivatives with their HIV-1 integrase inhibition activities. Four different models including stepwise-MLR, consensus stepwise-MLR, GAPLS-MLR, and consensus GAPLS-MLR with appropriate correlation between the calculated and experimental biological activities (pIC(50)) against HIV-1 integrase were generated. Predictive QSAR models were obtained with R (training) (2) values of 0.848, 0.862, 0.709, and 0.751 as well as R (test) (2) values of 0.521, 0.651, 0.502, and 0.775 for stepwise-MLR, consensus stepwise-MLR, GAPLS-MLR, and consensus GAPLS-MLR models, respectively. QSAR models are high efficiency in prediction of the pIC(50) in comparison with other models because of concerning the combination of quantum and molecular mechanical descriptors. Combination of quantum and molecular mechanical descriptors improved our models with high efficient test set activity prediction potency. The obtained results provided useful information for understanding the effects of polarizability, electronegativity, and especially functional groups such as aromatic nitrogens that are important for the activities of naphthyridine compounds. The developed QSAR models will be efficient for the rational design of potent naphthyridine derivatives against HIV-1 integrase activity.

In a patnet, author is Rounds, Heather R., once mentioned the new application about 100-49-2.

Dinuclear, strain-induced ring-opening reactions of vinylaziridines and vinylcyclopropanes are described. The previously reported [NDI]Ni-2(C6H6) complex (NDI = naphthyridine diimine) reacts with N-tosyl-2-vinylaziridine via C-N oxidative addition to generate a dinickel metallacyclic product. On the basis of this stoichiometric reactivity, the [NDI]Ni-2(C6H6) complex is shown to be a highly active catalyst for the rearrangement of vinylcyclopropane to cyclopentene. Notably, 2-phenyl-1-vinylcyclopropane undergoes regioselective activation at the less hindered C-C bond in contrast to the noncatalytic thermal rearrangement. DFT calculations provide insight into the ability of the Ni-Ni bond stabilize key intermediates and transition states along the catalytic pathway.

Future efforts will undeniably focus on the diversification of the new catalytic transformations. In my other articles, you can also check out more blogs about 100-49-2. Name: Cyclohexanemethanol.

Two novel facial-capping tris-naphthyridyl compounds, 2-chloro-5-methyl-7-((2,4-dimethyl-1,8-naphthyridin-7(1H)-ylidene)(2,4-dimethyl-1,8-naphthyridin-7-yl))methyl-1,8-naphthyridine (L-1) and 2-chloro-7-((2-methyl-1,8-naphthyridin-7(1H)-ylidene)(2-methyl-1,8-naphthyridin-7-yl)) methyl-1,8-naphthyridine (L-2), as well as their Cu(I) and Pb(II) complexes, [CuLa(PPh3)]BF4 (1) (PPh3 = triphenylphosphine, L-a = bis(2,4-dimethyl-1,8-naphthyridin-7-yl)(2-chloro-5-methyl-1,8-naphthyridin-7-yl)methane), [CuLb(PPh3)]BF4 (2) (L-b = bis(2-methyl-1,8-naphthyridin-7-yl)(2-chloro-1,8-naphthyridin-7-yl)methane), [Pb(OLa)(NO3)(2)] (3) (OLa = bis(2,4-dimethyl-1,8-naphthyridin-7-yl)(2-chloro-5-methyl-1,8-naphthyridin-7-yl)methanol) and [Pb(L-b)(2)][Pb(CH3OH)(NO3)(4)] (4), have been synthesized and characterized by X-ray diffraction analysis, MS, NMR and elemental analysis. The structural investigations revealed that the transfer of the H-atom at the central carbon to an adjacent naphthyridine-N atom affords L-1 and L-2 possessing large conjugated architectures, and the central carbon atoms adopt the sp(2) hybridized bonding mode. The reversible hydrogen transfer and a geometric configuration conversion from sp(2) to sp(3) of the central carbon atom were observed when Pb(II) and Cu(I) were coordinated to L-1 or L-2. The molecular energy changes accompanying the hydrogen migration and titration of H+ to different receptor-N at L-1 were calculated by density functional theory (DFT) at the SCRF-B3LYP/6-311++G(d,p) level in a CH2Cl2 solution, and the observed lowest-energy absorption and emission for L-1 and L-2 can be tentatively assigned to an intramolecular charge transfer (ICT) transition in nature.

In a patnet, author is Forensi, Silvia, once mentioned the new application about 132-64-9.

In this work, we describe the synthesis of 1,8,10-trisubstituted anthracenyl scaffolds that, bearing boronic acid functionalities, can act as multiple H-bonding donor systems. The trisubstituted anthracenyl derivatives are synthesized following two main synthetic pathways. Whereas in the first approach trisubstituted anthracenyl derivatives are prepared through the regioselective addition of the relevant organomagnesium nucleophile to 1,8-dichloroanthraquinone, in the second avenue a triflate-bearing anthracene is prepared by reduction of the anthraquinone into the anthrone precursor and functionalized through metal-catalysed cross-coupling reactions. Complementary studies of the Na2S2O4-mediated reduction of 1,8-dichloroanthraquinone allowed to shed further light on the possible mechanism of formation of the anthrone precursor, suggesting the presence of a cis-diol intermediate undergoing antiperiplanar elimination. Solid-state X-ray diffraction investigations of the bisboronic acids show that the molecules self-assemble into dimers through the formation of four H-1-bonds established between the anti-syn conformers of the boronic acid moieties. H-1-NMR titrations between bisboronic acids and tetra H-bond acceptor, diisoquinolino-naphthyridine, showed a significant shift of the -B(OH)(2) proton resonances, suggesting the presence of H-bonding interactions between both molecules.
