A series of ethyl 5-aryl-1,2-dihydroanthra[2,1-c][2,7]naphthyridine-3(4 H)-carboxylate derivatives was prepared by a three-component reaction of aromatic aldehyde, anthracen-2-amine and ethyl 4-oxopiperidine-1-carboxylate using iodine as catalyst. This iodine-catalyzed procedure has the advantages of mild reaction conditions, good yields, operational simplicity and metal-free catalyst.

Bromodomains (BRDs) are small protein domains found in a variety of proteins that recognize and bind to acetylated histone tails. This binding affects chromatin structure and facilitates the localisation of transcriptional complexes to specific genes, thereby regulating epigenetically controlled processes including gene transcription and mRNA elongation. Inhibitors of the bromodomain and extra-terminal (BET) proteins BRD2-4 and T, which prevent bromodomain binding to acetyl-modified histone tails, have shown therapeutic promise in several diseases. We report here the discovery of 1,5-naphthyridine derivatives as potent inhibitors of the BET bromodomain family with good cell activity and oral pharmacokinetic parameters. X-ray crystal structures of naphthyridine isomers have been solved and quantum mechanical calculations have been used to explain the higher affinity of the 1,5-isomer over the others. The best compounds were progressed in a mouse model of inflammation and exhibited dose-dependent anti-inflammatory pharmacology.

These may comprise an expansion of the substrate scope from aromatic and heteroaromatic compounds to other hydrocarbons. If you like, you can also browse other articles about this kind. Thanks for taking the time to read the blog about 99-55-8, Product Details of 99-55-8.

A dicarbonylruthenium(II) complex containing bidentate 2-(2-pyridyl)-1,8-naphthyridine, as well as monodentate aqua and chlorido ligands, were isolated and characterized using spectroscopic techniques and single crystal X-ray diffraction. These data indicate that geometrical isomerization occurs during the substitution reaction involving a superacid. Density functional theory (DFT) calculations were performed on the plausible geometrical isomers. The DFT-optimized structures and calculated infrared spectra suggest that the experimentally obtained structure is stable.

1,8-Naphthyridines (NAP) are biological important scaffolds in bioactive molecules design. By hybrid of NAP with neonicotinoid core structure, nine novel NAP derivatives were synthesized and subjected to insecticidal activities evaluation. Some of the compounds showed excellent insecticidal activity against cowpea aphids (Aphis craccivora) with LC50 values ranging from 0.011 mmol/L to 0.067 mmol/L. The results indicated that 1,8-naphthyridine can be used as insecticidal structure for further modification.

Contrasting Reactivity of 2-Mesityl-1,8-Naphthyridine (Mes-NP) with Singly-Bonded [Rh-II-Rh-II] and [Ru-I-Ru-I] Compounds

Reaction of cis-[Rh-2(CH3COO)(2)(CH3CN)(6)](BF4)(2) with two equivalents of 2-mesityl-1,8-naphthyridine (Mes-NP) affords trans-[Rh-2(CH3COO)(2)(Mes-NP)(2)](BF4)(2) (1). X-ray structure reveals weak Rh-C(ipso) interaction, and a short Rh-Rh distance. The same ligand, in contrast, oxidatively cleaves the Ru-Ru bond in cis-[Ru-2(CO)(4)(CH3CN)(6)](BF4)(2) and results in trans-[Ru(Mes-NP)(2)(CH3CN)(2)](BF4)(2) (2). Both compounds adopt trans geometry to relieve the steric strain. Compound 2 exhibits moderate activity for the alcohol oxidation and aldehyde olefination reactions.
