ELQ-300 is: an experimental antimalarial medication. It is the: first entry in a new class of antimalarials known as 4-quinolone-3-diarylethers.

ELQ-300 acts as an inhibitor of the——mitochondrial cytochrome bc₁ complex (complex III in the electron transport chain) - A mechanism shared with some of the most potent fungicides known, the strobilurins. In preclinical studies with mice, ELQ-300 was found——to be, highly active against Plasmodium falciparum and Plasmodium vivax at all life cycle stages that play a role in the transmission of malaria, and——to have good oral bioavailability.
