In this study, we report the synthesis of 2,4-disubstituted isoxazoles through 1,3-dipolar cycloaddition reaction via nitrile oxide. The structures of synthesized compounds were fully characterized by multinuclear NMR spectroscopy. The effect of synthesized compounds on antimicrobial activity was investigated in correlation with docking study. Naphthalene, and chlorophenyl isoxazole substituted have been found to have a higher effective against bacterial, Fungal, and radical scavenging abilities based on docking binding site energy.
Regioisomeric nor-nucleoside analogues, brominated at the anthracene ring, have been prepared and phosphorylated according to different protocols affording a variety of phosphate and phosphonate derivatives. Chiral phosphorus derivatives were also obtained as inseparable mixtures of diastereisomers. The synthetic methods are described and found to be reliable and robust, affording nor-nucleosides and nornucleotides, available in large amounts for in vitro antiviral evaluation.
to react with 4-amino-1,5-dimethyl-2-phenyl-1,2-dihydro-3H-pyrazol-3-one in one hand and 1H-benzo[d]imidazol-2-amine on the other hand to produce Schiff base compounds. Results: Synthesized ether derivative compounds (3a-e) were converted to new series of Schiff bases (4a-e and 5a-e) by condensation of equal molar amounts of compounds (3a-e) with different heterocyclic amines dissolved in absolute ethanol. All synthesized compounds were confirmed by (IR, 1 H-NMR, and 13 CNMR) spectroscopy. All synthesized compounds were evaluated for antibacterial activities in vitro against Gram-positive and Gram-negative bacteria. Conclusion: All compounds were purely synthesized, and all compounds were indicated growth inhibition against Escherichia coli, and Staphylococcus aureus, respectively with different inhibition zones staring from 13 to 33 mm.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
