1-Phenyl-2-trifluoromethyl-4-quinolone [PDF]
Acta Crystallographica Section E Structure Reports Online, 2007 In the title mol-ecule, C(16)H(10)F(3)NO, the N-bound phenyl ring is oriented nearly orthogonal to the quinolinyl ring in order to avoid steric clashes with the trifluoro-methyl substituent [dihedral angle 89.7 (1)°].

Regiocontrolled Nitration of 4-Quinolones at Ambient Conditions [PDF]
Synthetic Communications, 2015 Regiocontrolled nitration of 4-quinolone, the highly privileged scaffold, has been developed at ambient conditions. The nitro group can selectively be introduced at diverse positions simply by tuning the reactivity of the moiety. Discrimination is being achieved through the selective functionalization of the free N-H group.

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 ...
