Predict what's on your test 5 Must Know Facts For Your Next Test Quinolines function by inhibiting the enzyme DNA gyrase or topoisomerase IV, which is essential for bacterial DNA replication. Common examples of quinolines include chloroquine and hydroxychloroquine, which are used primarily for treating malaria. Resistance to quinolines can develop through mutations in the genes encoding their target enzymes or through efflux mechanisms. Quinolines can have side effects such as gastrointestinal discomfort, central nervous system effects, and, in rare cases, cardiotoxicity. They were first discovered in the early 20th century and have since undergone various modifications to improve efficacy and reduce resistance.
