Exploration of the novel fluoroquinolones with high inhibitory effect against quinolone-resistant DNA gyrase of Typhimurium.

Quinolone-resistant nontyphoidal is a pressing public health concern, demanding the exploration of novel treatments. In this study, we focused on two innovative synthetic fluoroquinolones, WQ-3034 and WQ-3154. Our findings revealed that these new compounds demonstrate potent inhibitory effects, even against mutant strains that cause resistance to existing quinolones. Hence, WQ-3034 and WQ-3154 could potentially be effective therapeutic agents against quinolone-resistant Typhimurium. Furthermore, the data obtained in this study will be baseline information for antimicrobial drug development.
