Electroreductive Intermolecular Coupling of 4‑Quinolones with Benzophenones: Synthesis of 2‑Substituted 4‑Quinolones [PDF]
ACS Omega, 2019 The electroreductive coupling of 1-alkoxycarbonyl-4-quinolones with benzophenones in the presence of trimethylsilyl chloride gave adducts reacted at the 2-position of 4-quinolones as trimethylsilyl ethers. The adducts were transformed to 2-(diarylhydroxymethyl)-4-quinolones.

Interactions of the 4-quinolones with other antibacterials [PDF]
Journal of Medical Microbiology, 1989 The effect of sub-inhibitory concentrations of 16 antibacterials on the bactericidal activity of the 4-quinolones nalidixic acid, ciprofloxacin and ofloxacin against Escherichia coli KL16 in nutrient broth was investigated. Sub-inhibitory concentrations of rifampicin, clindamycin, chloramphenicol, erythromycin or tetracycline antagonised the ...
