Current Opinion in Allergy and Clinical Immunology, 2003
Quinolones are potent antibacterial agents that can cause drug hypersensitivity reactions affecting different organs. A better understanding of the underlying mechanism and the level of crossreactivity within different quinolones is needed to handle and prevent these diseases.The adverse side-effects caused by quinolones are the result of different ...

Pacing and Clinical Electrophysiology, 2003
Quinolones block the rapid component of the delayed rectifier potassium current (Ik) in a dose dependent manner. This electrophysiological action translates into prolongation of the QT interval and may predispose to development of torsades de pointes. QT prolongation appears to be a class effect but there is a wide range of potency among class members.

Quinolone antibacterial agents were first introduced into the clinical environment in the early 1960s. The first qumolone to be clinically used was nalidixic acid, which was used for the treatment of enteric and urinary tract infections. As a result of increased clinical resistance to this drug, its use has declined.

Pharmaceutisch Weekblad Scientific Edition, 1986
The quinolones are synthetic antibiotics chemically related to nalidixic acid. Since its introduction, several structural analogues have been synthesized. A fundamental breakthrough was the addition of a fluorine atom. The quinolones interfere with bacterial DNA transcription by inhibiting the enzyme DNA gyrase, that so far has only been found in ...

Fluoroquinolones have broad antibacterial spectra and are active against most Gram-negative and many Gram-positive species. They exhibit excellent oral bioavailability, extensive tissue penetration, low protein binding, and a long elimination half-life.

Fluorinated quinolones — new quinolone antimicrobials
1992Paul Ehrlich started his research, called experimental chemotherapy, in 1902, and discovered Trypanrot in 1904 and Salvarsan in 1909. This was the first success of chemotherapy using man-made chemotherapeutic agents against microorganisms. Since the original observation by Fleming in 1929 of the effect of Penicillium notatum on a culture plate in his ...

Generation of ArS- and ArSe-Substituted 4-Quinolone Derivatives Using Sodium Iodide As an Inducer.
Journal of Organic Chemistry, 2018An operationally simple sodium iodide-mediated C-S and C-Se bond formation protocol involving substituted 4-quinolone and thiols/diselenide to generate different ArS/ArSe-substituted 4-quinolone derivatives in excellent yields was developed.
