Studies on the prophylactic and radical curative activity of RC-12 against Plasmodium cynomolgi in Macaca mulatta

The compound 4-(2-bromo-4,5-dimethoxyphenyl)-1,1,7,7-tetraethyldiethylenetriamine (RC-12) has been shown to be active against the exoerythrocytic (EE) stages of the malaria parasite. Experiments on Plasmodium cynomolgi in rhesus monkeys showed that single weekly doses of 25 mg per kg of body weight would prevent the development and/or maturation of EE stages. The usefulness of RC-12 for effecting radical cures is, however, still open to doubt.
