Antimalarial activities of salts of aminoquinolines with hydroxyaromatic acids were found to be higher than the parent components. The IC50 values of the salts were in the range of 5.9-20.3 μM against the chloroquine-resistant strain. Antimalarial actions on the parasites were found to be independent of iron chelation, inhibition of haemozoin formation, as well as independent of the anti-oxidant activity of the salts. A covalently linked amide containing compound N-(quinolin-8-yl)-2-(quinolin-8-yloxy)acetamide was identified to have potency similar to the other salts studied in the article.
