Synthesis and Antimicrobial Studies of 4-3-(3-Fluorophenyl)-4-formyl-1H-pyrazol-1-ylbenzoic Acid and 4-3-(4-Fluorophenyl)-4-formyl-1H-pyrazol-1-ylbenzoic Acid as Potent Growth Inhibitorsof Drug-Resistant Bacteria

摘要

Microbial resistance to antibiotics is an urgent and worldwide concern. Several pyrazole-derived hydrazones were synthesized by using benign reaction conditions. Several of these molecules are potent growth inhibitors of drug-resistant strains of Staphylococcus aureus and Acinetobacter baumannii with minimum inhibitory concentration values as low as 0.39 μg/mL. Furthermore, these molecules are nontoxic to human cells at high concentrations. Some of these molecules were tested for their ability to disrupt the bacterial membrane by using the SYTO-9/propidium iodide (BacLight) assay.
