New substituted 1,4-benzoxazine derivatives with potential intracellular calcium activity

Substituted 1,4-benzoxazines bearing an amino side chain at the 2- position were prepared and were found to have a moderate activity on intracellular calcium. Of the compounds studied it was found that those which possess a homoveratrylamino moiety exhibited superior potency. The chain length and the nature of the amine (4-fluorophenylpiperazine, 4- fluorobenzhydryloxyethylamine, N-substituted homoveratrylamine) is discussed. The 4-benzyl-3,4-dihydro-2-[3-[[2-(3,4-dimethoxyphenyl)ethyl]amino]propyl]- 2H-1,4-benzoxazine (3c) is the most potent derivative of the series with a ratio of IC50 values against PE (phenylephrine) and K+ of 2.1. Under these test conditions a ratio near 1 indicates potential intracellular calcium activity while a ratio greater than 100 an action on extracellular calcium influx.

Pd-Catalyzed Direct ortho-C-H Arylation of Aromatic Ketones Enabled by a Transient Directing Group

The Pd-catalyzed direct C(sp2)-H arylation of aromatic ketones using a transient directing group is described.

Scope and Mechanistic Analysis for Chemoselective Hydrogenolysis of Carbonyl Compounds Catalyzed by a Cationic Ruthenium Hydride Complex with a Tunable Phenol Ligand

A cationic ruthenium hydride complex, [(C6H6)(PCy3)(CO)RuH]+BF4- (1), with a phenol ligand was found to exhibit high catalytic activity for the hydrogenolysis of carbonyl compounds to yield the corresponding aliphatic products. The catalytic method showed exceptionally high chemoselectivity toward the carbonyl reduction over alkene hydrogenation. Kinetic and spectroscopic studies revealed a strong electronic influence of the phenol ligand on the catalyst activity. The Hammett plot of the hydrogenolysis of 4-methoxyacetophenone displayed two opposite linear slopes for the catalytic system 1/p-X-C6H4OH (rho = -3.3 for X = OMe, t-Bu, Et, and Me; rho = +1.5 for X = F, Cl, and CF3). A normal deuterium isotope effect was observed for the hydrogenolysis reaction catalyzed by 1/p-X-C6H4OH with an electron-releasing group (kH/kD = 1.7-2.5; X = OMe, Et), whereas an inverse isotope effect was measured for 1/p-X-C6H4OH with an electron-withdrawing group (kH/kD = 0.6-0.7; X = Cl, CF3). The empirical rate law was determined from the hydrogenolysis of 4-methoxyacetophenone: rate = kobsd[Ru][ketone][H2]-1 for the reaction catalyzed by 1/p-OMe-C6H4OH, and rate = kobsd[Ru][ketone][H2]0 for the reaction catalyzed by 1/p-CF3-C6H4OH. Catalytically relevant dinuclear ruthenium hydride and hydroxo complexes were synthesized, and their structures were established by X-ray crystallography. Two distinct mechanistic pathways are presented for the hydrogenolysis reaction on the basis of these kinetic and spectroscopic data. (Chemical Equation Presented).

Iodine-Catalyzed Oxidative Coupling to Construct C-O Bonds for the Synthesis of 2,3-Dihydrooxepines

The iodine-catalyzed catalytic formal [3 + 3 + 1] cycloaddition for the preparation of a seven-membered O-heterocyclic ring is presented, which is an achievement of methyl and carbonyl group reactivity of 3-methyl-5-pyrazolones to forge the Csp3-O bond. This novel protocol provides a straightforward and efficient access to structurally diverse fused O-heterocycles through an iodine-catalyzed iodination/Kornblum oxidation/oxidative coupling/C-O bond formation cascade reaction. This approach demonstrates the unprecedented concurrent realization of the unique reactivity among the methyl, methylene, and carbonyl groups in 3-methyl-5-pyrazolones for the construction of 2,3-dihydrooxepine rings. Moreover, a broad substrate scope displays a graceful diversity-oriented synthetic approach.

PYRROLIDINE DERIVATIVE OR SALT THEREOF

[PROBLEMS] To provide a compound which can be used for the treatment of a disease associated with a calcium-sensing receptor (CaSR), particularly hyperparathyroidism. [MEANS FOR SOLVING PROBLEMS] It is found that a novel pyrrolidine derivative having an aminomethyl group substituted by an arylaklyl group or the like or a salt thereof has an excellent CaSR agonistic modulation effect and also has an excellent selectivity in the inhibition of CYP2D6 which may cause a drug-drug interaction. Thus, the novel pyrrolidine derivative is useful as a therapeutic agent for a disease associated with CaSR (e.g., hyperparathyroidism, renal osteodystrophy and hypercalcemia).

Direct alpha-iodination of aryl alkyl ketones by elemental iodine activated by 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetrafluoroborate)

Selective introduction of an iodine atom at the alpha-carbonyl position in various aryl alkyl ketones was effectively achieved by reaction of target molecules with elemental iodine in the presence of N-F reagents. The best results were obtained by using 1-chloromethyl-4-fluoro-1,4-diazoniabicyclo[2.2.2]octane bis(tetra-fluoroborate) (Selectfluor F-TEDA-BF4) as the iodination mediator and methanol as the solvent. Despite a strongly activated aromatic ring, iodomethyl derivatives were thus exclusively obtained from the corresponding hydroxy and methoxy substituted acetophenone derivatives, 3-acetylindole and 2-acetylbenzofuran, while the alpha-iodo derivative was the main product in the case of iodination of 1,5,6,7-tetrahydro-4H-indol-4-one and 6,7-dihydro-1-benzothiophene-4(5H)-one.

Quinolinyl-Thienyl Chalcones as Monoamine Oxidase Inhibitors and their in Silico Modeling Studies

Mitochondrial enzymes, monoamine oxidases (MAO) are thought to be emerging and useful therapeutic target for neurodegenerative disorders. Monoamine oxidases have two isoforms, A and B. MAO-A is related to metabolism of amine neurotransmitters in the brain whereas MAO-B is concerned with aging related neurodegenerative disorders. Therefore, the identification, characterization and discovery of new and potent MAO-A and B inhibitors is crucial in advancing neurodegenerative therapeutic research. A series of quinolinyl-thienyl chalcones were tested against MAO-A and B and most of them revealed potent MAO-A and B inhibition. Compound 5i exhibited most potent MAO-A inhibition activity, having IC50 value of 0.047 muM, while 4l showed maximum inhibitory potency against MAO-B having IC50 value of 0.063 muM. Molecular modelling studies were performed against human MAO-A and MAOB to rationalize most probable binding site interactions.
