Electrocatalytic water oxidation using the oxidatively robust 2,7-[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine ligand (BPMAN)-based dinuclear copper(II) complex, [Cu-2(BPMAN)(-OH)](3+), has been investigated. This catalyst exhibits high reactivity and stability towards water oxidation in neutral aqueous solutions. DFT calculations suggest that the OO bond formation takes place by an intramolecular direct coupling mechanism rather than by a nucleophilic attack of water on the high-oxidation-state (CuO)-O-IV moiety.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

Th antiproliferative activity ofN-substituted 2,4-diamino-5-aryl-5,6,7,8,9,10-hexahydrobenzo[b][1,8]naphthyridine-3-carbonitriles was studied. Substituents in the 5- and 7-positions of the naphthyridine ring had strong influences on the activity; in the 1-position, weak influences. Compounds with a C-5 3,4,5-trimethoxyphenyl radical were significantly superior to other derivatives. The influences of other substituents were not precisely established; however, a C-7 substituent played a key role in the manifestation of biological activity.

A ruthenium complex containing a 1,9,10-anthyridine derivative, [Ru(L)(bpy)(2)](PF6)(2) ( [1] (PF6)(2); L = 1,13,14-triazadibenz[a,j]anthracene, bpy = 2,2′-bipyridyl), was synthesized. X-ray crystal structural analysis of [1](PF6)2 showed that L is coordinated to the Ru center as a bidentate ligand. When [1](PF6)(2) was dissolved in acetonitrile, a new complex incorporating one acetonitrile molecule, [Ru(L)(CH3CN)(bpy)(2)](PF6)(2) ([2] (PF6)(2)), was formed. X-ray crystallographic data revealed that, in [2](PF6)(2), L is coordinated to the Ru center in a monodentate fashion. The coordinated L in [2](PF6)(2) shows a unique haptotropic rearrangement in an acetonitrile solution.

Chemical Research Letters, May 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, and research on the structure and performance of functional materials. In an article, author is Moro, Artur J., once mentioned the application of 39156-41-7, Name is 4-Methoxybenzene-1,3-diamine sulfate. Now introduce a scientific discovery about this category, Recommanded Product: 4-Methoxybenzene-1,3-diamine sulfate.

A new organometallic alkynyl-gold(i) complex capable of exhibiting aggregation induced emission was designed and synthesized. The linear complex structure possesses a central Au(i) atom, bearing two axial ligands: (1) 1,3,5-triaza-7-phosphaadamantane and (2) 2-acetamido-7-ethynyl-1,8-naphthyridine. While the former accounts for its partial solubility in an aqueous environment, the latter acts as a receptor unit for binding guanosine nucleotides and derivatives via multiple hydrogen bonding interactions. At high concentrations, aggregation of the complex was observed by the formation of new absorption (lambda(max) similar to 400 nm) and emission bands (550-700 nm). Formation of aggregates of ca. 60 nm diameter was confirmed by Small Angle X-ray Scattering (SAXS). Disruption of the aggregates in the presence of guanosine derivatives resulted in a ratiometric signal with apparent association constants in the order of 10(5) M-1 and high sensitivity (around 63% signal change) which are, to the best of our knowledge, in line with the highest values recorded for nucleotide sensors based on hydrogen bonding and capable of working in water. Computational studies indicate the presence of additional hydrogen bonding interactions that account for the strong binding of the Au(i) complex to phosphorylated guanosine nucleotides.

Background: Antimicrobial resistance is found in all microorganisms and has become one of the biggest threats to global health. New antimicrobials with different action mechanisms are effective weapons to fight against antibiotic-resistance. Objective: This review aims to find potential drugs which can be further developed into clinic practice and provide clues for developing more effective antimicrobials. Methods: DNA replication universally exists in all living organisms and is a complicated process in which multiple enzymes are involved in. Enzymes in bacterial DNA replication of initiation and elongation phases bring abundant targets for antimicrobial development as they are conserved and indispensable. In this review, enzyme inhibitors of DNA helicase. DNA primase, topoisomerases, DNA polymerase and DNA ligase were discussed. Special attentions were paid to structures, activities and action modes of these enzyme inhibitors. Results: Among these enzymes, type II topoisomerase is the most validated target with abundantinhibitors. For type II topoisomerase inhibitors (excluding quinolones), NBTIs and benzimidazole urea derivatives are the most promising inhibitors because of their good antimicrobial activity and physicochemical properties. Simultaneously, DNA gyrase targeted drugs are particularly attractive in the treatment of tuberculosis as DNA gyrase is the sole type II topoisomerase in Mycobacterium tuberculosis. Relatively, exploitation of antimicrobial inhibitors of the other DNA replication enzymes are primeval, in which inhibitors of topo III are even blank so far. Conclusion: This review demonstrates that inhibitors of DNA replication enzymes are abundant, diverse and promising, many of which can he developed into antimicrobials to deal with antibiotic resistance.

In an article, author is Millet, Agustin, once mentioned the application of 620-92-8, Name is 4,4′-Methylenediphenol, molecular formula is C13H12O2, molecular weight is 200.23, category is naphthyridine. Now introduce a scientific discovery about this category, Quality Control of 4,4′-Methylenediphenol.

The cis- and trans-dirhodium(II,II) complexes cis-[Rh-2(mu-DTolF)(2)(mu-np)(MeCN)(4)][BF4](2) (1; DTolF = N,N’-di-p-tolylformamidinate and np = 1,8-naphthyridine), cis- and trans-[Rh-2(mu-DTolF)(2)(mu-qxnp)(MeCN)(3)][BF4](2)[2 and 3, respectively, where qxnp = 2-(1,8-naphthyridin-2-yl)quinoxaline], and trans-[Rh-2(mu-DTolF)(2)(mu-qxnp)(2)[BF4](2 )(4) were synthesized and characterized. A new synthetic methodology was developed that consists of the sequential addition of Jr-accepting axially blocking ligands to favor formation of the first example of a bis-substituted formamidinate-bearing trans product. Isolation of the intermediates 2 and 3 provides insight into the mechanistic requirements for obtaining 4 and the cis analogue, cis-[Rh-2(mu-DTolF)(2)(mu-qxnp)(2)[BF4](2 ) (5). Density functional theory calculations provide support for the synthetic mechanism and proposed intermediates. The metal/ligand-to-ligand charge-transfer (ML-LCT) absorption maximum of the trans complex 4 at 832 nm is red-shifted by 1173 cm(-1) and exhibits shorter lifetimes of the (ML)-M-1-LCT and (ML)-M-3-LCT excited states, 3 ps and 0.40 ns, respectively, compared to those of the cis analogue 5. The shorter excited-state lifetimes of 4 are attributed to the longer Rh-Rh bond of 2.4942(8) angstrom relative to that in 5, 2.4498(2) angstrom. A longer metal-metal bond reflects a decreased overlap of the Rh atoms, which leads to more accessible metalcentered excited states for radiationless deactivation. The (ML)-M-3-LCT excited states of 4 and 5 undergo reversible bimolecular charge transfer with the electron donor p-phenylenediamine when irradiated with low-energy light. These results indicate that trans isomers are a source of unexplored tunability for potential p-type semiconductor applications and, given their distinct geometric arrangement, constitute useful building blocks for supramolecular architectures with potentially interesting photophysical properties.
