The 1,8-naphthyridine and diiodine were selected as model molecules to investigate the possible effect of the strong N center dot center dot center dot I halogen bond on the electronic structures and properties of potential organic semiconductor building blocks. The N center dot center dot center dot I halogen bond in the crystal structure of the cocrystal formed between 1,8-naphthyridine and diiodine has an interaction energy of -21.41 kcal/mol. The cooperativity and anticooperativity between the strong halogen bond and other noncovalent interactions, including the hydrogen bond, tetrel bond and stacking interaction, were also studied in detail. The formation of the strong N center dot center dot center dot I halogen bond leads to the formation of the regularly layered structures of the cocrystal, which is a necessary condition for the organic semiconductor to conduct electrons or holes. On the other hand, the formation of the strong N center dot center dot center dot I halogen bond lowers both the energy of the lowest unoccupied molecular orbital of 1,8-naphthyridine and the energy gap of frontier molecular orbitals of 1,8-naphthyridine. These results clearly show that the strong halogen bond can be used as a cheap and effective tool for the design and synthesis of organic semiconductor materials.

Ferrocenylamido-naphthyridine conjugates [{(5,7-dimethyl-1,8-naphthyridin-2-yl)amino} carbonyl] ferrocene (L-1) and 1,1′-bis[{(5,7-dimethyl-1,8-naphthyridin-2-yl) amino} carbonyl] ferrocene (L-2) have been synthesized. Reaction of L-1 with [Cu(CH3CN)(6)][ClO4](2) affords [Cu(L-1)(2)][ClO4](2) (1) demonstrating tridentate coordination of the ligand utilizing naphthyridine (NP) nitrogens and carbonyl oxygen. Hydroxo-bridged neutral dirhenium(I) compound [K subset of {{Re(CO)(3)}(2)(mu-OH)(Fc(CONHNP)(CO (N) over bar NP))(2)}] (2) is reported in which the amido-NP arm of L-2 chelates a Re-I, and a K+ ion is encapsulated in a six-coordinate environment rendered by four NP nitrogens and two carbonyl oxygens involving all four arms of two L-2 ligands. Selective and reversible binding of K+ ion by the organometallic host has been recognized from electrochemical and fluorescence experiments. Partial hydrolysis of L-2 has provided a neutral metallamacrocycle [{Re(CO)(3)}(2){Fc(CO2)(CONHNP)}(2)] (3) consisting of alternate Fc and Re(CO)(3) units linked by carboxylate and amide-NP bridges. The rotational freedom of the ferrocenyl rings, the flexibility of the amide linker and the multi-site coordination of the ligands are demonstrated in the molecular structures of compounds 1-3.

We report the synthesis and characterization of a series of cationic, neutral, and anionic dicopper(I) complexes featuring a p-mesityl ligand and a naphthyridine-derived PNNP expanded pincer ligand. Structural characterization showed that the protonation state of the dinucleating ligand has a pronounced effect on the bending and tilting of the mu-mesityl ligand. DFT calculations indicate that the varying orientations of the mu-mesityl ligand are inherent due to changes in electronic structure rather than crystal-packing effects. NBO analysis reveals how the interactions that contribute to the three-center two-electron bond between the mu-mesityl ligand and the dicopper core change for the various degrees of observed bending and tilting.

The reaction of 2-aminopyridine (1) with ethoxymethylenemalonic ester gave 4-ethoxy-3-oxo-2-(pyridine-2-yl aminomethylene)-butyric acid ethyl ester (2) which on cyclization in the presence of hot PPA gave 4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carboxylic acid ethyl ester (3). The latter on reaction with hydrazine hydrate resulted in, 4-oxo-1,4-dihydro-[1,8] naphthyridine-3-carboxylic acid hydrazide (4). The reaction of 4 in acetic acid with benzaldehydes yielded 3-(5-phenyl-[1,3,4] oxadiazol-2-yl)-1H-[1,8] naphthyridin-4-ones (5). In another reaction, 4 on treatment with acetylacetone gave 3-(3,5-dimethyl-pyrazole-1-carbonyl)-1H-[1,8] naphthyridin-4-ones (6). The hydrazide 4 was further cyclized with carbon disulphide in the presence of potassium hydroxide followed by acidification to get 3-(5-mercapto-[1,3,4] thiadiazol-2-yl)-1H-[1,8] naphthyridin-4-ones (7).

A new methodology has been developed for the synthesis of novel 2-oxo-1,2-dihydro-1,8-naphthyridine-3-carboxylates from 2-aminonicotinaldehyde, Meldrum’s acid, and the corresponding alcohols in the presence of anhydrous iron(III) chloride as a cheap and readily available catalyst. The structure of the synthesized compounds was established by IR, H-1 NMR, and mass spectral data and elemental analyses. All the synthesized compounds were evaluated for their in vitro antibacterial and antifungal activity, and the activity of some derivatives was comparable with the activity of Ciprofloxacin and Nystatin used as reference drugs.

Novel fluorescent nanosensors, based on a naphthyridine receptor, have been developed for the detection of guanosine nucleotides, and both their sensitivity and selectivity to various nucleotides were evaluated. The nanosensors were constructed from polystyrene nanoparticles functionalized by (N-(7-((3-aminophenyl) ethynyl)-1,8-naphthyridin- 2-yl) acetamide) via carbodiimide ester activation. We show that this naphthyridine nanosensor binds guanosine nucleotides preferentially over adenine, cytosine, and thymidine nucleotides. Upon interaction with nucleotides, the fluorescence of the nanosensor is gradually quenched yielding Stern-Volmer constants in the range of 2.1 to 35.9mM(-1). For all the studied quenchers, limits of detection (LOD) and tolerance levels for the nanosensors were also determined. The lowest (3 sigma) LOD was found for guanosine 3′,5′-cyclic monophosphate (cGMP) and it was as low as 150 ng/ml. In addition, we demonstrated that the spatial arrangement of bound analytes on the nanosensors’ surfaces is what is responsible for their selectivity to different guanosine nucleotides. We found a correlation between the changes of the fluorescence signal and the number of phosphate groups of a nucleotide. Results of molecular modeling and zeta-potential measurements confirm that the arrangement of analytes on the surface provides for the selectivity of the nanosensors. These fluorescent nanosensors have the potential to be applied in multi-analyte, array-based detection platforms, as well as in multiplexed microfluidic systems.

New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 298-96-4, Name is Tetrazolium Red, molecular formula is , belongs to naphthyridine compound. In a document, author is Wang, Jiamian, Product Details of 298-96-4.

A facile label-free sensing method is developed for the one-step and highly sensitive fluorescent detection of DNA, which couples the specific C-C mismatch bonding and fluorescent quenching property of a trimethyl-substituted naphthyridine dye (ATMND) with the exonuclease III (Exo III) assisted cascade target recycling amplification strategy. In the absence of target DNA, the DNA hairpin probe with a C-C mismatch in the stem and more than 4 bases overhung at the 3′ terminus could entrap and quench the fluorescence of ATMND and resist the digestion of Exo III, thus showing a low fluorescence background. In the presence of the target, however, the hybridization event between the two protruding segments and the target triggers the digestion reaction of Exo III, recycles the initial target, and simultaneously releases both the secondary target analogue and the ATMND caged in the stem. The released initial and secondary targets take part in another cycle of digestion, thus leading to the release of a huge amount of free ATMND for signal transducing. Based on the fluorescence recovery, the as-proposed label-free fluorescent sensing strategy shows very good analytical performances towards DNA detection, such as a wide linear range from 10 pM to 1 mu M, a low limit of detection of 6 pM, good selectivity, and a facile one-step operation at room temperature. Practical sample analysis in serum samples indicates the method has good precision and accuracy, which may thus have application potentials for point-of-care screening of DNA in complex clinical and environmental samples.
