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...

Design and Synthesisof Potential Quinoline-BasedSDH Inhibitors Inspired by Quinine Alkaloids with Activity againstPhytopathogenic Fungi and Bacteria

Abstract In pursuit of environmentally friendly agrochemicals, we employed the natural quinine alkaloid scaffold as a lead for the design and synthesis of three series of structurally diverse quinine derivatives and systematically evaluated their in vitro antibacterial and antifu...
