[Antimalarial 6-aminoquinolines. XIV. 6-(4-Diethylamino-1-methylbutylamino)-4-methoxy-2-methyl- and -2,4-dimethylquinolines with variations of substituents in positions 5 and 8].
3 derivatives 2g--i of 6-(4-diethylamino-1-methylbutylamino)-4-methoxy-2-methylquinoline and 6 derivatives 2k--p of 6-(4-diethylamino-1-methylbutylamino)-2,4-dimethylquinoline were synthesized with variations of substituents in positions 5 and 8 (--H, --OH, --OCH3, --CH3, --Cl) with the aim of studying the influence of these substituents, which facilitate, complicate or prevent oxidation to o- and (or) p-quinones, on antimalarial activity and toxicity. One methoxy group is necessary for activity against Plasmodium vinckei in position 5 or 8, no substituent that prevents oxidation is allowed in para position to this methoxy group.
