Abstract:

Degradation of pyridines in waste water is an important issue for chemical and pharmaceutical industries. The biodegradation of 2,6-dimethylpyridine was investigated by the bacterium Arthrobacter crystallopoietes KM-4, which resulted in the formation of three metabolites: 2,6-dimethylpyridin-3-ol, 2,6-dimethylpyridin-3,4-diol, and 2,4-dioxopentanoic acid.

Abstract:

This research was undertaken to synthesizes and evaluate 3,5-dihydroxymethyl-4-(2-fluorophenyl)-2,6-dimethylpyridine and 4-(fluoromethyl)-2,6-dimethylpyridine as indicators of 19F NMR pH. A comparison of 3,5-dihydroxymethyl-4-(2-fluorophenyl)-2,6-dimethylpyridine to 4-(fluoromethyl)-2,6-dimethylpyridine showed that 4-(fluoromethyl)-2,6-dimethylpyridine has a large 19F chemical shift to pH, a suitable pKa value and a good water solubility.

With 2,4-dimethylpyridine, a 1:2 adduct is formed, where the nitrogen bases are in trans-positions of a TiCl4N2-octahedron, as also confirmed by an X-ray analysis

Abstract:

Cyclo-palladation and - platination of nitrogen donor ligands lead to insoluble μ- chloro dimers which give μ- bromo and μ- iodo dimers on metathesis with the appropriate lithium halide. Addition of pyridine or 2,6-dimethylpyridine to the cyclopalladated dimers gives monomeric complexes with the halogen trans to the metal-carbon bond, whereas addition of 2,6-dimethylpyridine to the cycloplatinated complexes gives the isomer with the halogen cis to the metal-carbon bond. The results are discussed in terms of the mechanism of the bridge cleavage reaction.

Abstract:

: A new synthesis of the 2,6-naphthyridine alkaloid 4-methyl-2,6-naphthyridine from Antirrhinum majus has been developed. Key steps are a regioselective oxidation of 3-bromo-4,5- dimethylpyridine to the corresponding 4-formyl derivative, and the annulation of the second pyridine ring by Suzuki-Miyaura cross-coupling using (E)-2-ethoxyvinylboronic acid pinacol ester as a masked acetaldehyde equivalent. This protocol gives the alkaloid in four steps starting from commercially available 3,4-dimethylpyridine in 15% overall yield. This annulation protocol should be useful for the synthesis of other

Abstract:

In the title monomeric trimethyltin(IV) isothiocyanate–4,4-dimethylpyridine adduct, [Sn(CH3)3(NCS)(C7H10N2)], the SnIV atom shows a trans-C3SnN2 trigonal bipyramidal coordination. The SnIV atom lies out of the equatorial plane by 0.033 (4) Å in the direction of the donor N atom of the N-heterocycle. The crystal studied was a non-merohedral twin with a minor component of 48.8 (2)%.

Abstract:

<em>The article presents the results of studies on the interaction of N-hydroxy 2,6</em><em>-</em><em>dimethylpyridine introduced into the composition as a physiologically active substance with ammonium derivatives. The studied polytherms of the system are characterized by the presence of crystallization fields; triple points corresponding to certain compositions have been found. Isotherms are constructed on the basis of polythermal sections using interpolation.</em>

Abstract:

Cyclooxygenase inhibitors as anti-inflammatory agents can be used in chemoprevention. Many in vitro and in vivo studies on human and animal models have explained the mechanisms of the chemopreventive effect of COX inhibitors such as: induction of apoptosis, inhibition of neoplasia, angiogenesis suppression, induction of cell cycle inhibition and inhibition of the expression of peroxisome proliferator-activated receptors. Here, biological evaluation of twelve different Schiff base derivatives of N-(2-hydrazine-2-oxoethyl)-4,6-dimethyl-2-sulfanylpyridine- 3-carboxamide are presented. Their in vi
