Abstract
Improvement in the treatment of malaria has been demonstrated with 5-arylalkoxy primaquine compounds of the formula ##STR1## wherein R.sub.2 represents H or methyl, R represents an alkylene group having from about 2 to about 12 carbon atoms, R' represents a substituted or non-substituted aryl moiety, such as phenyl and napthyl, and pharmaceutically acceptable salts thereof, wherein the salt forming acid may be organic or inorganic in nature. These primaquine related compounds are effective in malarial chemotherapy, by exerting plasmodicidal activity on malarial parasites present in both the blood and formed tissues of the mammalian host. The 5-arylalkoxy primaquine compounds of the invention are at least as effective in malarial treatment as the prior art 5-alkoxy primaquine compounds, but are not as toxic as the 5-alkoxy compounds at higher dosage ranges.
