[Antimalarial 6-aminoquinolines. VIII. 2- and 4-amino derivatives (author's transl)]

Ten 2- or 4-amino derivatives 10b-I of 6-(4-diethylamino-1-methylbutylamino)-5,8-dimethoxyquinoline were synthesised with the aim of studying the influence of these substituents on antimalarial activity and toxicity of the 6-aminoquinolines. The 4-dialkylamino derivatives 10c-h were less active against P. vinckei (mouse) than 4-alkoxy derivatives. The 4-amino derivative 10b was inactive.
