The title of the article was 《Design, Synthesis, Biological Evaluation and Molecular Docking Studies of 1,4-Disubstituted 1,2,3-Triazoles: PEG-400:H2O Mediated Click Reaction of Fluorescent Organic Probes under Ultrasonic Irradiation》.Application of 624-28-2 The author mentioned the following in the article:
A PEG-400:H2O mediated highly versatile, efficacious and selective “”Click reaction”” of fluorescent organic Probes under ultrasonic irradiation were reported. A rapid and efficient approach for the synthesis of 1,4-Disubstituted 1,2,3-triazoles I [R = (4-fluorophenyl)methyl, 2,4-dioxo-pyrimidin-5-yl, etc.] under Copper (I)-Catalyzed Azide-Alkyne [3 + 2] Cycloaddition (CuAAC) conditions in good to excellent yields in less time were described. This synthetic protocol were proved to endorse easy work-up under benign reaction conditions. The green solvent system employed was efficaciously reused several times without any loss of its activity in an aqueous medium. All the title compounds were characterized by using elemental anal., 1HNMR, 13CNMR, FTIR, and mass spectral data. The newly synthesized compounds were biol. evaluated for their antioxidant activity. The antioxidant activity resulted demonstrate that all compounds showed good to excellent antioxidant activity, particularly the compounds I [R = (4-bromophenyl)methyl, 5-bromo-2-pyridyl, pyrimidin-2-yl, 2,4-dioxo-pyrimidin-5-yl] exhibited promising radical scavenging activity. Further, photophys. properties of the compounds were accomplished using spectrofluorimeter. Compounds I [R = (3-chlorophenyl)methyl, (4-nitrophenyl)methyl, (4-cyanophenyl)methyl, thiazol-2-yl, 5-bromo-2-pyridyl, pyrimidin-2-yl, 2,4-dioxo-pyrimidin-5-yl] exhibited fluorescence in the visible region. Mol. docking studies suggested the antioxidant activity of synthesized compounds were due to the inhibition of neuronal nitric oxide synthase (HnNOS). In the experiment, the researchers used 2,5-Dibromopyridine(cas: 624-28-2Application of 624-28-2)
2,5-Dibromopyridine(cas: 624-28-2) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.Application of 624-28-2
