Perchlorate reduction to chloride by the dimolybdenum(II) core: Making a case for molybdenum cofactor in the perchlorate reductase enzyme

Ligand-transfer reaction from the quadruply bonded complex cis-[Mo-2(pzNP)(2)(OAc2][BF4](2) (1) (pzNP = 2-(2-pyrazinyl)-1,8-naphthyridine) to non-bonded dicopper(I) core proceeds with the concomitant oxidation of the [Mo2](4+) core by the perchlorate anion, resulting in the [Cu-2(mu-Cl)(pzNP)(2)][CIO4] (2) and oxo-molybdenum species. X-ray analysis of (2) shows the presence of a chloride anion bridging the two Cu(I) atoms. The chloride originates from the quantitative reduction of one perchlorate anion by the electron-rich dimolybdenum(11) species, mimicking the functional role of molybolenum cofactor in the perchlorate reducing bacteria.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 106-49-0, in my other articles.

2-amino-5,7-dimethyl-1,8-naphthyridine as a fluorescent reagent for the determination of nitrite

A new fluorescent reagent 2-amino-5,7-dimethyl-1,8-naphthyridine (ADMND) was proposed for the determination of trace nitrite. The reaction is based on the diazotization of naphthyridine amine with nitrite to form a diazonium salt that hydrolyzed when boiling to give hydroxyl group substituted naphthyridine. Fluorescence quenching degree of ADMND by nitrite ion is linear in the nitrite concentration range of 1 x 10(-7) to 2.5 x 10(-6) mol l(-1) with a detection limit of 4.06 x 10(-8) mol l(-1). Reaction and determination acidity for nitrite is the same which made the method much simpler compared with the widely accepted fluorescence method with DAN as a fluorescence reagent.

Acetic Anhydride Generated Imidazolium Ylide in Ring Closures onto Carboxylic Acids; Part of the Synthesis of New Potential Bioreductive Antitumor Agents

Acetic anhydride behaves as a traceless activating agent allowing thermal intramolecular condensation of 2-(benzimidazol-1-ylmethyl) benzoic and nicotinic acids. Autoxidation gives benzimidazo[1,2-b]isoquinoline-6,11-diones (intermediates characterized) and benzimidazo[2,1-g]-1,7-naphthyridine-5,12-diones in a facile, one-pot transformation. The 1,4-dimethoxy analogue of the former is converted into benzimidazo[1,2-b]isoquinoline-1,4,6,11-tetrone using cerium ammonium nitrate (CAN). The 1,7-naphthyridine-5,12-dione system readily ring-opens, and an X-ray crystal structure of the methanol adduct was obtained.

A slipped-CAG DNA-binding small molecule induces trinucleotide-repeat contractions in vivo

In many repeat diseases, such as Huntington’s disease (HD), ongoing repeat expansions in affected tissues contribute to disease onset, progression and severity. Inducing contractions of expanded repeats by exogenous agents is not yet possible. Traditional approaches would target proteins driving repeat mutations. Here we report a compound, naphthyridine-azaquinolone (NA), that specifically binds slipped-CAG DNA intermediates of expansion mutations, a previously unsuspected target. NA efficiently induces repeat contractions in HD patient cells as well as en masse contractions in medium spiny neurons of HD mouse striatum. Contractions are specific for the expanded allele, independently of DNA replication, require transcription across the coding CTG strand and arise by blocking repair of CAG slip-outs. NA-induced contractions depend on active expansions driven by MutS beta. NA injections in HD mouse striatum reduce mutant HTT protein aggregates, a biomarker of HD pathogenesis and severity. Repeat-structure-specific DNA ligands are a novel avenue to contract expanded repeats. Naphthyridine-azaquinolone specifically binds slipped-CAG DNA intermediates, induces contractions of expanded repeats and reduces mutant HTT protein aggregates in cell and animal models of Huntington’s disease.

Ruthenium-Catalyzed Enantioselective Hydrogenation of 1,8-Naphthyridine Derivatives

The first asymmetric hydrogenation of 2,7-disubstituted 1,3-naphthyridines catalyzed by chiral cationic ruthenium diamine complexes has been developed. A wide range of U-naphthyridine derivatives were effectively hydro-genated to give 1,2,3,4-tetrahydro-1,8-naphthyridines with up to 99% ee and full conversions. The method provides a practical and facile approach to the preparation of valuable chiral heterocyclic building blocks and useful motifs for a new kind of P,N-ligand.

Bimetallic cooperative effect on O-O bond formation: copper polypyridyl complexes as water oxidation catalyst

The performance of water oxidation catalysis by a Cu-based polypyridyl complex, [Cu-II(TPA)(OH2)](2+) (1H; TPA = tris-(pyridylmethyl)amine), has been investigated in neutral aqueous solution by electrochemical methods. Compared with our previously reported binuclear catalyst, [(BPMAN)(Cu-II)(2)(-OH)](3+) (2; BPMAN = 2,7-[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine), mononuclear catalyst 1 has a higher overpotential and lower catalytic activity toward water oxidation under the same conditions. Experimental results revealed that the O-O bond formation occurred via a water nucleophilic attack mechanism in which formal Cu-IV(O) is proposed as a key intermediate for the mononuclear catalyst 1H. In contrast, for the binuclear catalyst, O-O bond formation was facilitated by bimetallic cooperation between the two Cu-III centers.

One-Pot Synthesis of Densely Substituted 1,2,3,4-Tetrahydro-1,6-naphthyridine Mediated by Isocyanide-Assisted Reduction of C-C Double Bond

Molecular architectures possessing the combination of heteroaromatic and saturated N-heterocycles are of great importance because of their higher solubility in the gastrointestinal tract due to weak crystal packing in the three-dimensional structure. Other biological activity like selectivity is also increased in a positive way. However, compared to fully aromatic fused heterocycles, synthesis of partially saturated fused heterocycles is much more difficult since the later needs greater control over the reaction conditions. In this context, 1,2,3,4-tetrahydronaphthyridines (THNADs) are essential part of pharmaceutically important natural products and drug molecules. However, the synthesis of THNAD is seldom reported in literature. To the best of our knowledge, this is the first report of metal-free one pot synthesis of 1,2,3,4-tetrahydro-1,6-naphthyridines without starting from any nitrogen heterocycles in water. Moreover, this study discloses the involvement of isocyanide in a chemical reaction whose net effect is only to reduce a C=C bond which is unusual in isocyanide literature.
