Studies concentrating on noncovalent weak interactions between the organic base of 5,7-dimethyl-1, 8-naphthyridine-2-amine, and carboxylic acid derivatives have led to an increased understanding of the role 5.7-dimethyl-1,8-naphthyridine-2-amine has in binding with carboxylic acid derivatives. Here anhydrous and hydrous multicomponent organic salts of 5,7-dimethyl-1,8-naphthyridine-2-amine have been prepared with carboxylic acids that ranged from monocarboxylic acid to tricarboxylic acid such as p-nitrobenzoic acid, 5-sulfosalicylic acid, L-tartaric acid, 1,3,5-benzene tricarboxylic acid, and citric acid. The five crystalline forms reported are proton-transfer complexes of which the crystals and complexes were characterized by X-ray diffraction analysis, IR, mp, and elemental analysis. These structures adopted homo or hetero supramolecular synthons or both. Analysis of the crystal packing of 1-5 suggests that there are N-H center dot center dot center dot O, and O-H center dot center dot center dot O hydrogen bonds (charge assisted or neutral) between acid and base components in all of the salts. Except the classical hydrogen bonding interactions, the secondary propagating interactions also play an important role in structure extension. These weak interactions combined, all the complexes displayed 3D framework structure. (C) 2011 Elsevier B.V. All rights reserved.

New derivative of heteroannulated chromone identified as 5-methyl-8H-benzo[h]chromeno[2,3-b][1,6] naphthyridine-6(5H),8-dione (5, MBCND) was easily and efficiently synthesized from DBU catalyzed condensation reaction of 2-aminochromone-3-carboxaldehyde (1) with 4-hydroxy-1-methylquinolin-2(1H)-one (2). The same product 5 was isolated from condensation reaction of aldeyde 1 with 3-(4-hydroxy-l-methyl-2-oxo-1,2-dihydroquinolin-3-yl)-3-oxopropanoic acid (3) or ethyl 4-(4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinolin-3-yl)-2,4-dioxobutanoate (4). Structure of compound (5, MBCND) was deduced based on their elemental analyses and spectral data (IR, H-1 NMR and mass spectra). Density Functional Theory (DFT) calculations at the B3LYP/6-311G (d,p) level of theory have been carried out to investigate the equilibrium geometry of the novel compound (5, MBCND). Moreover, total energy, energy of HOMO and LUMO and Mullikan atomic charges were calculated. In addition, the dipole moment, theoretical study of the electronic structure, nonlinear optical properties (NLO), and natural bonding orbital (NBO) analysis and orientation have been performed and discussed. Also the electronic absorption spectra were measured in polar (methanol) as well as non polar (dioxane) solvents and the assignment of the observed bands has been discussed by TD-DFT calculations. The correspondences between calculated and experimental transitions energies are satisfactory. (C) 2016 Elsevier B.V. All rights reserved.

In an article, author is Ismayilov, Rayyat Huseyn, once mentioned the application of 5959-52-4, Name is 3-Amino-2-naphthoic acid, molecular formula is C11H9NO2, molecular weight is 187.1947, category is naphthyridine. Now introduce a scientific discovery about this category, Product Details of 5959-52-4.

Through a pyrimidine and naphthyridine-containing triamine ligand, N-2-(pyrimidin-2-yl)-N-7-(2-(pyrimidin-2-ylamino)-1,8-naphthyridin-7-yl)-1,8-naphthyridine-2,7-diamine (H3N9-2pm), defective metal string complex [Ni-8.33(N-9-2pm)(4)(NCS)(2)](PF6)(2) (1) was successfully synthesized and structurally characterized. The complex consists of a linear metal chain and four deprotonated supporting ligands which are helically wrapped around the metal score. X-Ray crystallographic studies revealed that the complex (1) crystallizes in space group P2(1)/c of the monoclinic system. The small J value (J = -2.90 cm(-1)) suggests quite a weak magnetic interaction throughout the molecule of complex (1). The weak magnetic interaction in the defective complex indicates that the spin exchange in metal string occurs through the metal core rather than the bridging ligands. The electrochemical study on complex 1 shows abundant redox properties and facility to the reduction in its cyclic voltammogram by displaying three reversible redox couples at E-1/2 = – 0.35, – 0.69 and – 0.88 V.

Chemical Research Letters, May 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. , Recommanded Product: 5959-52-4, 5959-52-4, Name is 3-Amino-2-naphthoic acid, molecular formula is C11H9NO2, belongs to naphthyridine compound. In a document, author is Harding, Drew P., introduce the new discover.

A series of aryl-substituted naphthyridine-based sensors for 9-alkylguanine was analyzed using density functional theory and correlated ab initio methods. First, the 2-acetamido-1,8-naphthyridine backbone of these sensors was examined with rigorous ab initio methods and was shown to exhibit a guanine-binding energy commensurate with that of cytosine. Second, computational analyses of a guanine-specific fluorescent sensor from Fang and co-workers (Org. Lett. 2016, 18, 1724) resulted in a revised binding model and showed that p-stacking interactions with a pendant pyrenyl group are vital for strong guanine binding. Finally, 24 related guanine sensors with varying aryl groups were studied. Overall, it was found that both the geometry and the point of attachment of the pendant aryl groups significantly impact the guanine-binding affinity. This occurs through both the direct modulation of the pi-stacking interactions with guanine and the secondary geometric effects that influence the strength and number of hydrogen bonds between guanine and the ethylenediamine linker connecting the arene to the naphthyridine backbone.

The potential utility of systematic synthetic strategy will be applicable to efficient generations of chemical libraries of compounds to find ‘hit’ molecules. I hope my blog about 5959-52-4 is helpful to your research. Recommanded Product: 5959-52-4.

DNA binding position and binding affinity of drugs are important information that helps medicinal chemists in synthesis of new drugs. We used molecular docking and molecular dynamics simulation to reveal binding strength of thieno[2,3-b]benzo[1,8]naphthyridine derivatives to DNA. Molecular docking showed that molecules with more steric hindrance select groove position in DNA structure. Other molecules are intercalated between base pairs of GC and AT. Restrained electrostatic potential (RESP) charges, root mean square deviation (RMSD), and total potential analyses were performed. RMSD and total potential analyses showed that all simulations have stability for MMGBSA analysis. Binding affinity of all drugs was derived via MMGBSA analysis. Thermodynamics analysis showed that binding affinity of groove binding drugs is less than that of intercalating ones. Also, it was found that a linear relationship exists between RESP charges and Delta G (pred). Additionally, our results demonstrated the highest affinity for molecules carrying substituent groups of-OCH3 and-CH3.

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 5959-52-4. Recommanded Product: 3-Amino-2-naphthoic acid.

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.
