II/IV enzyme (the target in most Gram-positive bacteria) or DNA gyrase (the target in Gram-negative bacteria), preventing the bacteria from unwinding their DNA and undergoing either DNA replication or transcription. The majority of drugs in clinical use are actually quinoline derivatives that belong to the subset fluoroquinolones, which have a fluorine atom attached to the central ring system, often at the C-6 or C-7 position.

The synthesis of 4-hydroxyquinolines and 4-quinolones is of great importance to a variety of fields, but most notably to the medical sciences due to their use as chemotherapeutic bactericidal drugs through their ability to kill bacteria. This mechanism involved disabling the bacterial topoisomerase

of the molecule via an electrocyclic ring closing. For this step, the Schiff base must be heated to ~250 °C for the ring closure to occur. Furthermore, the type of solvent used is very important to ensuring high yields of the 4-hydroxyquinoline product. In the early work, the cyclization was

accomplished by heating the Schiff base without a solvent and the yields were very moderate (below 30%). Limpach reported many years later that the yields in the cyclization were raised to 95% in many cases when an inert solvent, such as
