Article abstract of DOI:10.1021/jm00350a016

A series of nuclear and side-chain analogues of 4-methylprimaquine incorporating an alkoxy group in 5-position of the quinoline nucleus has been prepared.The compounds were tested for suppresive antimalarial activity against Plasmodium berghei in mice and for radical curative antimalarial activity against Plasmodium cynomolgi in the rhesus monkey.Although the toxicity problems characteristic of the 8-aminoquinolines were not overcome, several of the compounds, suprisingly, were highly effective as both blood and tissue schizonticidal agents.
