Design, Synthesis, and Biological Evaluation of Novel, Fluorinated Camptothecin Derivatives as Potential Topoisomerase I Inhibitors

Abstract Camptothecin (CPT), a classical topoisomerase I (TOP I) inhibitor, shows potent antitumor activity but is limited by toxicity and lactone instability. Herein, structural optimization of the CPT scaffold was conducted via A-ring fluorination and C-7 and C-17 modifications...
