2-Aminopyridine-3-carbonitrile derivative 1 reacted with each of malononitrile, ethyl cyanacetate, benzylidenemalononitrile, diethyl malonate, and ethyl acetoacetate to give the corresponding [1,8]naphthyridine derivatives 3, 5, 8, 11, and 14, respectively. Further annulations of 3, 5, and 8 gave the corresponding pyrido[2,3-b][1,8]naphthyridine-3-carbonitrile derivative 17, pyrido[2,3-h][1,6]naphthyridine-3-carbonitrile derivatives 18 and 19, respectively. The reaction of 1 with formic acid, formamide, acetic anhydride, urea or thiourea, and 4-isothiocyanatobenzenesulfonamide gave the pyridopyrimidine derivatives 20a,b, 21, 22a,b, and 26, respectively. Treatment of compound 1 with sulfuric acid afforded the amide derivative 27. Compound 27 reacted with 4-chlorobenzaldehyde and 1H-indene-1,3(2H)-dione to give the pyridopyrimidine derivative 28 and spiro derivative 30, respectively. In addition, compound 1 reacted with halo compounds afforded the pyrrolopyridine derivatives 32 and 34. Finally, treatment of 1 with hydrazine hydrate gave the pyrazolopyridine derivative 35.

We demonstrate a designed scaffold-hop approach to the discovery of 2,8-disubstituted-1,6-naphthyridine- and 4,6-disubstituted-isoquinoline-based dual CDK8/19 ligands. Optimized compounds in both series exhibited rapid aldehyde oxidase-mediated metabolism, which could be abrogated by introduction of an amino substituent at C5 of the 1,6-naphthyridine scaffold or at C1 of the isoquinoline scaffold.

Here, we demonstrate that a series of naphthyridine derivatives, naphthyridine carbamate tetramer (NCTn), can bind to the RNA CGG/CGG triad comprised of two single-stranded regions of a hairpin loop and a tail. Complete suppression of the binding by a single mutation indicated simultaneous binding of NCTn between hairpin loop and single stranded tail, leading to the formation of NCTn-induced pseudoknot.

Neutral tribromo(2-phenyl-1,8-naphthyridine)gold(III), AuBr3(N-N), has been prepared by reaction of KAuBr4 with the ligand in CHCl3/C2H5OH and was characterized by H-1 NMR spectroscopy and X-ray diffraction. The molecular and crystal structure of AuBr3(N-N) center dot 0.5 THF (triclinic, P1, a = 11.314(2), b = 12.350(3), c = 14.628(3) angstrom, alpha = 107.96(3), beta = 98.86(3), gamma = 107.29(3)degrees, Z = 4, 173 K) shows coordination of the N-8 nitrogen atom situated in the unsubstituted pyridine ring to the planar four-coordinate Au-III center. Whereas the AuBr3N best planes and the coordinated naphthyridine rings are not far from orthogonal (omega similar to 105 degrees), the phenyl substituents were found in the crystal with a ca. 22 degrees dihedral angle relative to the naphthyridine plane. Intermolecular Au center dot center dot center dot Br distances close to the sum of the van der Waals radii indicate very weak interactions to form a quasi-dimeric arrangement in the crystal.

The synthesis of cationic dirhodium(II) complexes by partial or total substitution of the acetate groups of [Rh-2(OAC)(4)] with different homoleptic neutral bidentate ligands has been attempted. The ligand 1,8-naphthyridine gave the best results: substitution of one as well as of all four acetate ligands is possible, giving rise to mono-, di- and tetra-cationic complexes. One of the resulting tetrasubstituted complexes has been structurally characterised and found to exhibit the expected lantern-shaped structure. All cationic complexes have been investigated as catalysts in different reactions involving silanes: promising results have been obtained, particularly in the silylformylation of alkynes.

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.

In an article, author is Bouarfa, Salima, once mentioned the application of 91-76-9, Name is 2,4-Diamino-6-phenyl-1,3,5-triazine, molecular formula is C9H9N5. Now introduce a scientific discovery about this category, Application of 91-76-9.

Thienylzinc halides and related compounds prepared by deprotonation followed by transmetalation were used in copper-catalyzed amination using N-benzoyloxy secondary amines. By extending the reaction to 1,5-naphthyridine, it was showed that the competitive dimer formation observed in the case of thiophenes was linked with the low stability of some thienylamines rather than homocoupling. Interestingly, thienylzinc halides and related compounds prepared by transmetalation of thienylmagnesium halides, either prepared from their bromo-precursors or generated by deprotometalation, were satisfactorily employed in cobalt-catalyzed aminations. Finally, aminothiophenes were involved in copper-catalyzed mono- and di-N-arylations, affording differently substituted di- and triphenylamines.

Application of 91-76-9, Because enzymes can increase reaction rates by enormous factors and tend to be very specific, typically producing only a single product in quantitative yield, they are the focus of active research.you can also check out more blogs about 91-76-9.
