Used in pharmaceutical research as a key intermediate in the synthesis of antimalarial drugs. It serves as a building block for quinoline-based compounds that exhibit activity against Plasmodium species. Also investigated for its potential in developing anticancer agents due to its ability to intercalate DNA and inhibit topoisomerase enzymes. Shows promise in the development of kinase inhibitors for treating inflammatory diseases and certain types of tumors. Its derivatives are explored for antimicrobial and antiviral properties, particularly in targeting RNA viruses. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug candidates.
