Abstract: Herein, we describe 39 novel quinolone compounds bearing a hydrophilic amine chain and varied substituted benzyloxy units. These compounds demonstrate broad-spectrum activities against acid-fast bacterium, Gram-pos. and -neg. bacteria, fungi, and leishmania parasite. Compound 30 maintained antitubercular activity against moxifloxacin-, isoniazid-, and rifampicin-resistant Mycobacterium tuberculosis, while 37 exhibited low micromolar activities (<1 μg/mL) against World Health Organization (WHO) critical pathogens: Cryptococcus neoformans, Acinetobacter baumannii, and Pseudomonas aeruginosa. Compounds in this study are metabolically robust, demonstrating % remnant of >98% after 30 min in the presence of human, rat, and mouse liver microsomes. Several compounds thus reported here are promising leads for the treatment of diseases caused by infectious agents.

The mixture was stirred at 50°C for 18 h, and then the reaction was filtered under vacuum. The solvent was removed under reduced pressure and the crude product was purified on a Biotage pre-packed silica gel column (EtOAc:Hexane 12percent to 100percent EtOAc) to afford ethyl l-(3- bromobenzyl)-5-methyl-lH-l,2,4-triazole-3-carboxylate (1.25 g, 60percent) as a viscous oil.

KOH (112 mg, 1 mmol, 5 eq) and phase transfer catalyst 1k (12.1 mg, 0.02 mmol, 10 mol%) followed by p-xylene (1 mL). After the mixture was stirred at rt for 30 min, BnBr (71.3 uL, 0.6 mmol, 3 eq) was added, and the stirring was continued at rt for additional 12 h (monitored by TLC analysis).
