We’ll tell you more about this compound (cas:60827-45-4).

A novel generation method of optically active 1,2-diols with excellent optical purity (>98% enantiomeric excess) from their racemates was developed using the resting cells of Alcaligenes sp. DS-S-7G. This method was based on microbial enantioselective oxidation of the racemic 1,2-diols. When 1% 1,2-butanediol was used as a substrate, the degradation reaction in the presence of NAD+ could be carried out 8 times in 200 h.

Two copper complexes 17Fnac2Cu(C6H6) and 17Fnac2CuCO containing the monoanionic, perfluorinated β-diketiminate 17Fnac2- ligand (I) (17Fnac2 = FC[C(CF3)N(C6F5)]2) were synthesized and characterized by IR and NMR spectroscopy (1H, 13C, 19F), cyclovaltammometry (CV), elemental anal. and single crystal X-ray diffraction. The perfluorinated 17Fnac2- ligand marginally reduces the π-back-bonding capacity of the copper center to the carbonyl group in 17Fnac2CuCO when compared with the corresponding 16Fnac2- substituted complexes but substantially when compared with the fluorine free substituted derivatives Quantum chem. calculations gave deeper insight into the bonding situation of this carbonyl complex, while CV studies were performed to determine the oxidation potential of 17Fnac2Cu(C6H6) in solution Based on these data, the influence of the degree of fluorination in different β-diketimine ligands on the electronic nature of the corresponding copper complexes is discussed.

Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 4553-62-2, is researched, SMILESS is N#CC(C)CCC#N, Molecular C6H8N2Journal, Article, Research Support, Non-U.S. Gov’t, Bioorganic & Medicinal Chemistry called Synthesis and biological evaluation of aroylguanidines related to amiloride as inhibitors of the human platelet Na+/H+ exchanger, Author is Laeckmann, Didier; Rogister, Francoise; Dejardin, Jean-Victor; Prosperi-Meys, Christelle; Geczy, Joseph; Delarge, Jacques; Masereel, Bernard, the main research direction is pyridine benzene isostere amiloride preparation sodium hydrogen exchanger inhibitor; structure amiloride isostere activity inhibitor sodium hydrogen exchanger.SDS of cas: 4553-62-2.

Pyridine and benzene bioisosteres of amiloride such as I and II were synthesized and evaluated for their inhibitory potency against the sodium-hydrogen exchanger involved in intracellular pH regulation. Substituted diaminochloro-2-pyridinecarbonyl and diaminochloro-3-pyridinecarbonyl guanidines are prepared from 2-chloro-6-methyl-3,5-dinitropyridine and 2-methyl-1,5-pentanedinitrile, resp. Dichloro- and trichloropyridine-3-carbonyl guanidines, and simple pyridinecarbonyl and benzoyl guanidines are also prepared Several benzene derivatives and compounds bearing an carbonylguanidine moiety in the meta position of the pyridine nitrogen were much more potent than amiloride, but less so than the pyrazine inhibitor III (R = Et; R1 = Me2CH). II is the most active mol. in assays measuring the reduction in human platelet swelling due to sodium ion uptake and in assays of the inhibition of sodium ion uptake, with IC50 values of 0.8 μM in both assays. Replacement of the pyrazine ring of amiloride III (R = R1 = H) by a pyridine or a Ph ring improved the inhibitory potency for the sodium-hydrogen exchanger involved in intracellular pH regulation in the order Ph > pyridine > pyrazine.

Cu(I)-α-ketocarboxylate complexes with aryl substituted iminoethylpyridines were prepared and shown to exhibit variable coordination modes of the α-ketocarboxylate ligand. Reaction with O2 induces decarboxylation of the α-ketocarboxylate, and the derived Cu-O intermediate(s) was intercepted, resulting in hydroxylation of an arene substituent on the supporting N-donor ligand. Theor. calculations provided intriguing mechanistic notions for the process, notably implicating hydroxylation pathways that involve novel [CuI-OOC(O)R] and [CuII-O-• ↔ CuIII:O2-]+ species.
