Synthesis and preliminary biological evaluation of potent and selective 2-(3-alkoxy-1-azetidinyl) quinolines as novel PDE10A inhibitors with improved solubility

We report the discovery of a novel series of 2-(3-alkoxy-1-azetidinyl) quinolines as potent and selective PDE10A inhibitors. Structure-activity studies improved the solubility (pH 7.4) and maintained high PDE10A activity compared to initial lead compound 3, with select compounds demonstrating good oral bioavailability. X-ray crystallographic studies revealed two distinct binding modes to the catalytic site of the PDE10A enzyme. An ex vivo receptor occupancy assay in rats demonstrated that this series of compounds covered the target within the striatum.

Utilization of optically active secondary phosphine-boranes: synthesis of P-chiral diphosphines and their enantioinduction ability in rhodium-catalyzed asymmetric hydrogenation

Abstract Both enantiomers of tert-butylmethylphosphine-borane have been used for the synthesis of P-chiral diphosphines and/or their borane complexes. The enantiopure borane complex of 1,2-bis(tert-butylmethylphosphino)ethane (t-Bu-BisP?) was prepared in high yield from the secondary phosphine-borane and 1,2-dichloroethane. A mono-chelated Rh-complex of t-Bu-MiniPHOS was prepared and its catalytic activity was examined in the asymmetric hydrogenation of some representative functionalized alkenes. Synthesis of three new P-chiral phosphine ligands with quinoline or quinoxaline backbone is also described together with their enantioinduction ability.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Application In Synthesis of 2,3-Dichloroquinoxaline, you can also check out more blogs about2213-63-0

Conformational behavior of pyrazine-bridged and mixed-bridged cavitands: A general model for solvent effects on thermal “vase-kite” switching

The controllable switching of suitably bridged resorcin[4]arene cavitands between a “vase” conformation, with a cavity capable of guest inclusion, and a “kite” conformation, featuring an extended flattened surface, provides the basis for ongoing developments of dynamic molecular receptors, sensors, and molecular machines. This paper describes the synthesis, X-ray crystallographic characterization, and NMR analysis of the “vase-kite” switching behavior of a fully pyrazine-bridged cavitand and five other mixed-bridged quinoxaline-bridged cavitands with one methylene, phosphonate, or phosphate bridge. The pyrazine-bridged resorcin[4]arene cavitand displayed an unexpectedly high preference for the kite conformation in nonpolar solvents, relative to the quinoxaline-bridged analogue. This observation led to extensive solvent-dependent switching studies that provide a detailed picture of how solvent affects the thermal vase-kite equilibration. As for any thermodynamic process in the liquid phase, the conformational equilibrium is affected by how the solvent stabilizes the two individual states. Suitably sized solvents (benzene and derivatives) solvate the cavity of the vase form and reduce the propensity for the vase-to-kite transition. Correspondingly, the kite geometry becomes preferred in bulky solvents such as mesitylene, incapable of penetrating the vase cavity. As proposed earlier by Cram, the kite form is preferred at low temperatures due to the more favorable enthalpy of solvation of the enlarged surface. Furthermore, the kite conformation is more preferred in solvents with substantial hydrogen-bonding acidity: weak hydrogenbonding interactions between the mildly basic quinoxaline and pyrazine nitrogen atoms and solvent molecules are more efficient in the open kite than in the closed vase form. Vase-to-kite conversion is entirely absent in dipolar aprotic solvents lacking any H-bonding acidity. Thermal vase-kite switching requires fully quinoxaline- or pyrazinebridged cavitands, whereas pH-controlled switching is also applicable to systems incorporating only two or three such bridges.

A family of molecular nickel hydrogen evolution catalysts providing tunable overpotentials using ligand-centered proton-coupled electron transfer paths

Two new nickel dithiolate derivatives have been examined for their electrocatalytic activity for the hydrogen evolution reaction (HER) in attempts to clarify whether the overpotential for the HER can be tuned upon varying the ligand-centered reduction potential that triggers the HER by the catalysts. We demonstrate the validity of this approach to achieve desirable tunability in the overpotential for the HER.

Searching for Practically Useful P-Chirogenic Phosphine Ligands

In this account, the design, synthesis, and application of P-chirogenic phosphine ligands that have been mainly carried out in our laboratory over the last three decades are described. Various enantiopure P-chirogenic phosphine ligands have been efficiently prepared by using phosphine boranes as intermediates. Conformationally rigid and electron-rich P-chirogenic phosphine ligands possessing C2 symmetry as well as a bulky alkyl group and a small group at the phosphorus atoms exhibit excellent enantioselectivities and catalytic efficiency in a variety of transition-metal-catalyzed asymmetric reactions. Enantiopure 2,3-bis(tert-butylmethylphosphino)quinoxaline (QuinoxP*) is an air-stable crystalline solid that shows superior enantioinduction ability in catalytic asymmetric syntheses. Mechanistic studies of Rh-catalyzed asymmetric hydrogenation using structurally simple P-chirogenic phosphine ligands, such as tBu-BisP*, are briefly described. (Figure presented.).

Computational and electrochemical analysis on quinoxalines as corrosion inhibitors for mild steel in acidic medium

In this investigation, quinoxaline derivatives namely, 2-(5-(2-chlorophenyl)-3-phenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (CPTQ) and 2-(3,5-diphenyl-4,5-dihydro-1H-pyrazol-1-yl)naphtho[2,3-d]thiazole (DPTQ) were synthesized and applied as corrosion inhibitors for mild steel (MS) in15% HCl solution. The corrosion inhibition behaviour of CPTQ and DPTQ was studied through weight loss measurement, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The maximum corrosion inhibition efficiency of DPTQ and CPTQ was found to be 96.01 and 95.62%, respectively at 100 ppm concentration and 303 K temperature. Potentiodynamic polarization studies showed that CPTQ and DPTQ act as mixed type inhibitors. Surface morphology of uninhibited and inhibited MS specimens was characterized using AFM and SEM studies. DFT, molecular dynamic simulations and calculation of Fukui functions were performed for correlation of theoretical parameters with the experimental results.
