Quinolone-3-amidoalkanol: A New Class of Potent and Broad-Spectrum Antimicrobial Agent
Dube, Phelelisiwe S. ; Angula, Klaudia T. ; Legoabe, Lesetja J. , et al. ACS Omega,2023,8(19):17086-17102. DOI: 10.1021/acsomega.3c01406 PubMed ID: 37214682

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.

94% | With sodium carbonate; In N-methyl-acetamide; (2S)-N-methyl-1-phenylpropan-2-amine hydrate; | Production of N-methyl-N-(4'-t-butylbenzyl)-1-naphthylmethylamine <strong>[65473-13-4]N-methyl-1-naphthylmethylamine hydrochloride</strong> (2.1 g; 0.01 mole) was dissolved in 50 ml of dry dimethylformamide, and 3.71 g (0.035 mole) of anhydrous sodium carbonate was added. The mixture was stirred at room temperature, and 2.49 g (0.011 mole) of p-t-butylbenzyl bromide was added. The mixture was reacted at 30 to 40 C. for 5 hours. Ice water was added to the reaction mixture, and the mixture was extracted with toluene. The organic layer was washed with water, and toluene was evaporated. The residue was chromatographed on a silica gel column, and eluted with 5% ethyl acetate/n-hexane. The elude was concentrated to give 2.98 g (yield 94%) of an oily substance. |
