  Malaria is a protozoal parasitic disease that is widespread in tropical and subtropical regions of Africa, Asia, and the Americas and causes more than 800,000 deaths per year. The continuing emergence of multidrug-resistant Plasmodium falciparum drives the ongoing need for the development of new and effective antimalarial drugs. Our previous work has explored the preliminary structural optimization of 4(1H)-quinolone ester derivatives, a new series of antimalarials related to the endochins. Herein, we report the lead optimization of 4(1H)-quinolones with a focus on improving both antimalarial potency and bioavailability. These studies led to the development of orally efficacious antimalarials including quinolone analogue 20g, a promising candidate for further optimization.

  Ethyl 1,4-dihydro-1-ethyl-4-oxoquinoline-3-carboxylate and 29 of its mono-, di- and tri-fluoro and/or -chloro derivatives were synthesized and their H-1, C-13 and F-19 NMR spectra were recorded. H-1,C-13 and F-19 chemical shifts, J(HH), J(FH), J(CF) and J(FF) coupling constants are reported. The C-13 substituent chemical shift values of the chloro and fluoro substituents were calculated by linear multiple regression.
