Abstract Cytochrome bc 1 is a validated drug target of Plasmodium falciparum , the parasite that causes the most lethal form of malaria. The inhibition of cytochrome bc 1 leads to the shutdown of the mitochondrial metabolism and the consequent arrest of pyrimidine biosynthesis essential for parasite development. Aiming to rationalize the stereoelectronic properties and extend the knowledge on a novel series of 4‐pyridonimines guiding the search of antimalarial drugs, we carried out an extensive DFT comparative characterization. Results show electronic similarity with clopidol, a known bc 1 complex inhibitor containing the 4(1 H )‐pyridone scaffold. © 2010 Wiley Periodicals, Inc. Int J Quantum Chem, 2011
