Used in the synthesis of antimalarial agents due to its quinoline core and amino side chain, which are critical for activity against Plasmodium species. The structure allows for modification to enhance drug resistance profiles and improve pharmacokinetics. Employed in research for developing next-generation antimalarials with better efficacy and reduced side effects. Also explored for its potential in treating autoimmune diseases and certain cancers due to immunomodulatory properties linked to quinoline derivatives.
