A review paper on Au(III) cyclometallated compounds with 2-arylpyridines (2-phenylpyridine, 2-benzylpyridine, 2-benzoylpyridine, 2-phenoxypyridine, 2-phenylsulfanylpyridine, 2-anilinopyridine, 2-(naphth-2-yl)pyridine, 2-(9,9-dialkylfluoren-2-yl)pyridines, 2-(dibenzofuran-4-yl)pyridine, and their derivatives) analogues (2-arylquinolines, 1- 3-arylisoquinolines, 7,8-benzoquinoline), 113 reference...

A novel series of pyridine ring containing diaryl urea derivatives (R1-R9) were synthesized in four chemical steps using pyridine-2-carboxylic acid as starting material. The compounds design by Autodock vina the crystal structure Kinase domain Human B-raf (PDB ID: 4DBN) to get insights into structural requirements for anticancer activity. In vitro activity against cell line (MCF-7) showed that ...

In the title compound, [ZnI2(C34H31N3)], the Zn(II) atom is four-coordinated by two I atoms and the pyridine N atoms from the bidentate 6'-phenyl-2,2'-bi-pyridine ligand in a distorted tetra-hedral geometry.

А para-chlorophenyl substituent was firstly obtained into the structure of pyridyl-substituted 4-nitrosopyrazole by cyclocondensation hydrazine hydrate with corresponding isonitroso-β-dicarbonyl compounds. The previously unknown 3(5)-(4-chlorophenyl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles and 3(5)-alkyl(aryl)-5(3)-pyridine-(3(4))-yl-4-nitroso-1H-pyrazoles is proved studied in detail mod...

Nitrogen-substituted polycyclic aromatic hydrocarbons (NPAHs) have been proposed to play a key role in the astrochemical evolution of the interstellar medium, but the formation mechanism of even their simplest building block - the aromatic pyridine molecule - has remained elusive for decades. Here we reveal a potential pathway to a facile pyridine (C5H5N) synthesis via the reaction of the cyano...

Chelidamic acid (4-hy-droxy-pyridine-2,6-dicarb-oxy-lic acid) and 2,6-diamino-pyridine react to form the title salt, C(5)H(8)N(3) (+)·C(7)H(4)NO(5) (-); there are two formula units in the asymmetric unit. The pyridine N atom of 2,6-diamino-pyridine is protonated whereas chelidamic acid is deprotonated at both carboxyl-ate groups but protonated at the N atom; the reaction involves intra- and int...

In the binuclear title compound, [Ag2(C11H11N3)2](ClO4)2·2C2H6SO, the complex cation is centrosymmetric, with the unique Ag(I) cation coordinated by two pyridine N atoms from two symmetry-related N-(pyridine-2-ylmeth-yl)pyridine-3-amine ligands in a geometry slightly distorted from linear [N-Ag-N = 170.78 (9)°], resulting in the formation of a 16-membered cyclic dimer. The two pyridine rings co...
