Synthesis and characterization of novel oxazines and demonstration that they specifically target cyclooxygenase 2 [PDF]

open access: yes, 2015
In the present study, we used solution combustion synthesis-bismuth oxide (Bi2O3) as catalyst for the simple and efficient synthesis of 1,2-oxazine based derivatives of 6-fluoro-3-(piperidin-4-yl)benzo[d]isoxazoles, 1-arylpiperazine and carbazoles.

Synthesis and reductive cleavage of 3-(2-flurophenyl) and 3-(4-flurophenyl)-cyclopent-5-en[d]isoxazolines by raney nickel in trifluroacetic acid [PDF]

open access: yes, 2013
3-Fluoro arylcycloopent-5-en[d]isoxazolines have been obtained via the 1,3-dipolar cycloaddition of cyclopentadiene to aromatic nitrile oxides. The reductive cleavage of these isoxazolines by Raney nickel in trifluoroacetic acid led to corresponding ...

Synthesis, Antimicrobial Evaluation, and Docking Study of Some New Isoxazoline Derivatives Derived from Chalcones

open access: yesJournal of the Turkish Chemical Society, Section A: Chemistry
New 2-Isoxazoline derivatives containing furan moieties were synthesized from chalcones as starting materials, followed by antimicrobial activity. Chalcones were synthesized by reacting p-methoxy acetophenone or 3,4-(methylenedioxy)acetophenone with ...

Inhibition of oncogenic transcription factor REL by the natural product derivative calafianin monomer 101 induces proliferation arrest and apoptosis in human B-lymphoma cell lines [PDF]

open access: yes, 2015
Increased activity of transcription factor NF-κB has been implicated in many B-cell lymphomas. We investigated effects of synthetic compound calafianin monomer (CM101) on biochemical and biological properties of NF-κB.
