Exploration of Novel “Ferroxazide/Ferrazone” Derivatives as Antitrypanosomatid Agents: Design, Synthesis, and Biological Efficacy

open access: yesApplied Organometallic Chemistry, Volume 39, Issue 1, January 2025.
A series of novel ferrocene derivatives, mimics of the clinical antibiotics, nifuroxazide and nitrofurazone, termed ferroxazides and ferrazones, respectively, were synthesized and evaluated for antitrypanosomatid activities. The ferroxazide 15 bearing dimethylamino moiety was identified in vitro as hit against Trypanosoma congolense strain but ...
