Two imidazolyl derived 1,8-naphthyridine compounds (2,7-diimidazolyl-1,8-naphthyridine (a), and 2-benzimidazolyl-5,7-dimethyl-1,8-napthyridine (b)) were synthesized and structurally characterized by X-ray crystallography. The compound a co-crystallizes with one ethanol and two water molecules to give compound 1. Compound 1 crystallizes in the triclinic, space group P-1, with a = 6.943(2) angstrom, b = 9.009(3) angstrom, c = 13.760(3) angstrom, alpha = 96.793(2)degrees, beta = 97.431(3)degrees, gamma = 107.080(2)degrees, V = 804.6(4) angstrom(3), Z = 2. Compound 1 forms a 3D interpenetrated network through hydrogen bonds. Compound b cocrystallizes with three and one half water molecules to form 2. Compound 2 crystallizes in the monoclinic, space group C2/c, with a = 24.926(8) angstrom, b = 10.608(3) angstrom, c = 16.751(5) angstrom, b = 110.133(4)degrees, V = 4159(2) angstrom(3), Z = 8. The free water molecules form six-membered rings, these water rings connect the naphthyridine to form one dimensional chain when viewed from b axis. The naphthyridyl rings in a and b axis are connected through C-H center dot center dot center dot pi, and pi-pi interactions, due to the weak interactions the compound shows 3D network structure.

Luminescent materials simultaneously exhibiting superior luminescence efficiency, thermally activated delayed fluorescence (TADF) and aggregation-induced emission (AIE) properties in the solid state are eagerly required for highly efficient non-doped organic light-emitting diodes (OLEDs). Herein, two new emitters, namely ND-AC and CND-AC, featuring a naphthyridine or cyano-naphthyridine segment as the electron acceptor and an acridine unit as the electron donor were designed, synthesized and investigated. The nearly orthogonal molecular configuration of the target emitters not only endows them with small energy differences between singlet and triplet states for ensuring TADF character but also affords a remarkable AIE feature. Due to the high photoluminescence quantum yields, and excellent TADF and AIE characteristics, the doped and non-doped OLEDs based on ND-AC exhibit outstanding performances with maximum external quantum efficiencies of 16.8% and 12.0%, respectively. These results demonstrate that the naphthyridine-based emitters have a promising application in OLEDs.

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 1066-54-2 is helpful to your research. Product Details of 1066-54-2.

We have previously synthesized a series of 1,8-naphthyridine-3-carboxamide derivatives to identify potential anti-cancer/anti-inflammatory compounds. Three derivatives, 7-chloro-N-(3-(cyclopentylamino)-3-oxo-1-phenylpropyl)-6-fluoro-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-22), 7-chloro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-31) and 7-chloro-6-fluoro-N-(2-hydroxy-3-oxo-1-phenyl-3-(phenylamino)propyl)-4-oxo-1-(prop-2-yn-1-yl)-1,4-dihydro-1,8-naphthyridine-3-carboxamide (C-34) demonstrated high cytotoxicity against a number of cancer cell lines and inhibited secretion of IL-1-beta and IL-6. In the present study, C-22, C-31 and C-34 were assessed for modulation of pro-inflammatory cytokines, TNF-alpha and IL-8, chemokine RANTES and NO produced by lipopolysaccharide (LPS)-treated mouse Dendritic cells (DCs). Among the 3 compounds, C-34 showed the most potent inhibition of inflammatory markers in DC model at 02 and 2 mu M. C-34 also significantly downregulated the secretion of TNF-alpha, IL-1-beta and IL-6 by murine splenocytes and THP-1 cells against IFS induced levels. In vitro effects of C-34 on bone marrow toxicity were assessed in CFU-GM assay. Human CPU-GM population was comparatively more sensitive to C-34 (0.1-10 mu M) than murine CPU-GM. IC50 values for murine and human CPU-GM were not attained. C-34 was further examined for in vivo suppression of LPS induced cytokines in a mice model. At doses ranging from 125 to 5 mg/kg, C-34 led to significant inhibition of TNF-alpha, IL-1-beta and MIP-1-alpha. At the highest dose of 5 mg/kg, C-34 also protected LPS-treated mice against endotoxin-induced lethality. In conclusion, C-34 demonstrates anti-inflammatory activity in vitro and in vivo in addition to cytotoxic properties. This finding suggests its potential for further development as a synthetic naphthyridine derivative with dual anti-cancer and anti-inflammatory (cytokine inhibition) properties.

The effect of a peripheral disulfide bridge substituent on the phenolic O-H bond dissociation energy (BDE) and the ionization potential (IP) of naphthyridine diol has been studied by density functional theory (DFT) calculation. Compared with naphthalene diol, the substituent of a peripheral disulfide bridge group is very efficient in reducing the BDE, whereas the insertion of nitrogen atoms into the naphthalenic ring only slightly changes the BDE of O-H bond but dramatically enhances the IP. It is similar with the stereoelectronic effect of the heterocyclic ring for the well-known alpha-tocopherol antioxidant and leads to a highly delocalized spin distribution. With the incorporation of these two aspects, a potential antioxidant is expected to be more active and more stable than alpha-tocopherol.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 1066-54-2, in my other articles. Quality Control of Ethynyltrimethylsilane.

We report that a polyhedral oligomeric silsesquioxane (POSS) core in a dendrimer can enhance the affinity of the molecular recognition via hydrogen bonds between 1,8-naphthyridine and guanosine nucleotides. The complexation of the naphthyridine ligands with a series of guanosine nucleotides was investigated, and it is shown that the POSS core should play a significant role in the stabilization of the complexes via hydrogen bonds. Finally, we demonstrate that the 1,8-naphthyridine ligand can selectively recognize guanosine triphosphate by assisting with the POSS-core dendrimer.

Novel calamitic liquid crystals with asymmetrically substituted structure base on the dibenzo[c,h][2,6]naphthyridine (DBN) moiety as an electron-deficient core, 2-(4-decylphenyl)dibenzo[c,h][2,6]-naphthyridine (C10-Ph-DBN), 2-chloro-8-decyl-DBN (Cl-DBN-C10) and 2-decyl-8-phenyl-DBN (Ph-DBN-C10), were synthesized and their carrier transport properties were investigated. The lower ordered smectic phase of SmA emerged in a very wide temperature range of 130 degrees C in all DBN derivatives, which allowed us to study the carrier transport properties in SmA phase in detail for the first time: we purified Cl-DBN-C10 enough to evaluate the carrier transport property in the SmA phase by time-of-flight method. It showed the temperature and electric field dependence of the mobility, indicating the energetic disorder of transport levels. We analyzed it within the framework of the Gaussian disorder model for electrons and obtained a Gaussian width of the density of states to 109meV in the SmA. This is the first experimental result analyzed for the SmA phase in calamitic liquid crystals with nonnegligible dipole moment.
