چکیده

As a part of our ongoing research in the exploration of novel antimicrobial agents, we report herein novel synthesis of hybrid molecules 4-methyl-7-(2-oxo-2-(5-(substitutedthio)-1,3,4oxadiazol-2-yl)ethoxy)-2H-chromen-2-ones and 4-substitutedbenzylidene-3-methyl-1-(2-((4methyl-2-oxo-2H-chromen-7-yl)oxy)acetyl)-1H-pyrazol-5(4H)-ones by combining coumarin ring with 1,3,4-oxadiazole and pyrazole scaffolds respectively. All the synthesized compounds have been characterized by chemical analysis, IR, H NMR, C NMR and mass spectroscopy. All the compounds have been evaluated for their in vitro antimicrobial activity against Staphylococcus aureus, Escherichia coli and fungi Aspergillus niger using serial broth dilution method. All the synthesized compounds displayed antimicrobial activity. Among all the compounds 7c and 7d have been emerged as highly potent molecules with 75 μg/mL potency.

Novel Oxadiazole Thioglycosides as Potential Anti- Acinetobacter Agents

The glycosylation of 1,3,4-oxadiazole-2-thiones has been performed with peracetylated β-pyranosyl bromide in the presence of potassium carbonate. Deprotection of acetylated thioglycosides was necessary for increasing their antibacterial effects. The structure of nucleosides were confirmed by 1H NMR, 13C NMR and HRMS. The anomeric protons of nucleosides c1–4 were assigned to the doublet, confirm...
