Synthesis of novel azabicyclo derivatives containing a thiazole moiety and their biological activity against pine-wood nematodes

To explore a new skeleton with nematicidal activity, a series of novel azabicyclo derivatives containing a thiazole moiety were designed, synthesized and evaluated for their nematicidal activities. The bioassay results against pine-wood nematodes (Bursaphelenchus xylophilus) showed that most of the title compounds displayed nematicidal activity at a concentration of 40 mg/L. Especially, the title compounds2-((8-methyl-8-azabicyclo[3.2.1]octan-3-yl)oxy)-4-(4-chlorophenyl)thiazole (7e), 2-((8-methyl-8-azabicyclo[3.2.1]octan-3-yl)thio)-4-phenylthiazole (10a) and 2-((8-methyl-8-azabicyclo [3.2.1]octan-3-yl)thio)-4-(4-chlorophenyl)thiazole (10e) exhibited more than 90% mortality against Bursaphelenchus xylophilus.

Antimicrobial evaluation and action mechanism of chalcone derivatives containing quinoxaline moiety

Abstract: A series of chalcone derivatives containing quinoxaline moieties were synthesized, and their antibacterial activities were evaluated. Antibacterial bioassays indicated that some of the compounds exhibited significant antibacterial activity against Xanthomonas axonopodis pv. Citri (Xac), Xanthomonas oryzae pv. oryzae (Xoo), and Ralstonia solanacearum (Rs) at the concentrations of 50 or 100?mug/cm3. 50% effective concentration (EC50) values of (E)-3-(pyridin-2-yl)-1-[4-(quinoxalin-2-yloxy)phenyl]prop-2-en-1-one against Xac, Xoo, and Rs were 6.72, 15.17, and 9.29?mug/cm3, respectively, which were better than those of bismerthiazol (44.31, 42.46, and 62.36?mug/cm3, respectively). Scanning electron microscopy (SEM) was employed to analyze the mechanism of antibacterial action of that compound toward Xac. Graphical abstract: [Figure not available: see fulltext.].

Electrophile-Induced Cyclization of 3-Alkynyl-2-arylquinoxalines: A Method for Benzo- and Naphthophenazine Synthesis

A facile synthesis of benzo[a]-, naphtho[1,2-a]- and naphtho[2,1-a]phenazines by ICl-promoted 6-endo-dig cyclization of 3-alkynyl-2-arylquinoxalines has been developed. The starting 3-alkynyl-2-arylquinoxalines were synthesized from 2,3-dichloroquinoxaline by two successive Sonogashira and Suzuki?Miyaura reactions. The method works well for 3-alkynyl-2-arylquinoxalines bearing various functional groups at the alkyne moiety. The arrangement and nature of the substituent in the 2-aryl fragment affect the regioselectivity of the cyclization. For the substrate of one particular type, namely 2-(4-methoxyphenyl)-3-(p-tolylethynyl)quinoxaline, the treatment with ICl leads to the alternative 5-endo-dig cyclization followed by demethylation of the methoxy group to give a spirocyclohexadienone derivative.

Synthesis and Photophysical Characterization of Several 2,3-Quinoxaline Derivatives: An Application of Pd(0)/PEG Nanoparticle Catalyst for Sonogashira Coupling

We have reported synthesis of monoalkynyl- and dialkynyl-quinoxalines using Pd(0)/PEG nanoparticles as a catalyst and the tandem cyclization of the dialkynequinoxalines with sodium azide in high yields. The structures of all synthesized compounds were confirmed by IR, NMR and ESI-MS. The derivatives showed the absorption maxima at the region of 370 to 442?nm and emission maxima at the region of 386 to 539?nm with high fluorescence intensity in chloroform. It suggests that compounds 4b, 4c, 5b and 5c can be potential candidates for optical device applications.

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.
