Alternating pi-conjugated copolymers of 1,8-naphthyridine-2,6-diyl (1,8-Nap) with 9,9-dioctylfluorene-2,7-diyl (P(Flu-Ph-1,8-Nap)) and 2,5-didodecyloxy-1,4-phenylene (P(ROPh-Ph-1,8-Nap)) have been synthesized by Pd-catalyzed organometallic polycondensation. The copolymers showed UV-vis absorption peaks at around 390 nm in o-dichlorobenzene. The polymers were photoluminescent both in o-dichlorobenzene and in the solid state. In o-dichlorobenzene, the emission peaks of P(Flu-Ph-1,8-Nap) and P(ROPh-Ph-1.,8-Nap) appeared at lambda(EM) = 440 and 471 nm, with quantum yields of 87% and 66%, respectively. Electrochemical data revealed that 1,8-Nap behaved as a typical electron-accepting unit. When P(Flu-Ph-1,8-Nap) was treated with 10-camphorsulfonic acid, the emission peak shifted to lambda(EM) = 598 nm. (C) 2011 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 49: 4204-4212, 2011

Now introduce a scientific discovery about this category, Quality Control of 9H-Fluoren-9-ol.

Pressure-induced irreversible chemical reactions of naphthalene, 2,3-naphthyridine (2,3-Nap), and 1,5-naphthyridine (1,5-Nap) were observed after compression (> 16-18 GPa) at room temperature. Regardless of the initial materials, amorphous products in which sp(3) carbon was formed were obtained after the samples were recovered at ambient pressure. The X-ray photoelectron spectroscopy (XPS) of the product from naphthalene indicated that the carbon sp(3)/sp(2) ratio was much lower than that of benzene nanothreads. Nitrogen remained in the amorphous products from 1,5-Nap and 2,3-Nap and bonded to both sp(3) and sp(2) carbons.

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 1689-64-1 is helpful to your research. Quality Control of 9H-Fluoren-9-ol.

Methyl 2-carbamate-1,8-naphthyridine thiophenolate derivative (NCTP) has been designed and synthesized, which can selectively bind to guanine derivatives. We immobilized NCTP on gold electrode and performed cyclic voltammetry analysis for guanosine sensing. The current blockage data obtained from these NCTP immobilized electrodes suggest that electrodes have higher selectivity for 2′-deoxyguanosine monophosphate (dGMP) than 2′-deoxythymidine monophosphate (dTMP), 2′-deoxycytidine monophosphate (dCMP), and 2′-deoxyadenosine monophophate (dAMP). Thus, synthetic reader molecule NCTP, which has complementary hydrogen bonding surface for guanine derivatives, could be useful for the sensing of guanosine mononucleotides and polynucleotides.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, spectroscopic, and theoretical assessments of solvent structures and their interactions with reaction intermediates. 1588-83-6, Name is 4-Amino-3-nitrobenzoic acid, SMILES is C1=C([N+]([O-])=O)C(=CC=C1C(=O)O)N, belongs to naphthyridine compound. In a document, author is Madak, Joseph T., introduce the new discover, Formula: https://www.ambeed.com/products/1588-83-6.html.

We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore and form new electrostatic interactions through strategically positioned H-bond accepting groups. This effort led to the discovery of potent quinoline-based analogues 41 (DHODH IC50 = 9.71 +/- 1.4 nM) and 43 (DHODH IC50 = 26.2 +/- 1.8 nM). A cocrystal structure between 43 and DHODH depicts a novel water mediated H-bond interaction with T63. Additional optimization led to the 1,7-naphthyridine 46 (DHODH IC50 = 28.3 +/- 3.3 nM) that forms a novel H-bond with Y356. Importantly, compound 41 possesses significant oral bioavailability (F = 56%) and an elimination t(1/2) = 2.78 h (PO dosing). In conclusion, the data supports further preclinical studies of our lead compounds toward selection of a candidate for early-stage clinical development.

In a document, author is Hussein, Mahmoud A., introduce the new discover.

A new series of heteroaromatic polyazomethines containing 1,8-naphthyridine moieties in the polymer backbone were synthesized with a solution polycondensation technique. A new heteroaromatic monomer containing 1,8-naphthyridine moieties (4-ethoxy-2,7-dicarboxaldehyde-1,8-naphthyridine) was synthesized with an analogous synthetic sequence and confirmed by elemental and spectral data. The resulting polymers were characterized by elemental, spectral analyses, solubility and viscometry measurements. All the synthesized polyazomethines had better solubility in polar aportic solvents. The thermal properties of those polymers were evaluated by thermogravimetric analysis, differential thermogravimetry, and differential thermal analysis measurements and correlated to their structural units. All the polymers had nearly similar maximum polymer decomposition temperatures, which were in the range 557-577 degrees C. A very large difference between the glass transitions (92-222 degrees C) was observed. In addition, with gel permeation chromatography, the molecular weight determination of selected examples of those polymers was evaluated. The values of the average molecular weight for polyazomethines 7b and 7c were 34,914 and 24,859, respectively. On the other hand, the biological screening of all of the synthesized polyazomethines was performed in variety of bacteria and fungi. Most of the polyazomethines showed a significant influence against Gram-negative bacteria. The minimum inhibitory concentration of the most active polymers was 0.05 mg/mL.(C) 2012 Wiley Periodicals, Inc. J Appl Polym Sci, 2012

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.
