abstract: 23 derivatives 17a--z of 6-(4-diethylamino-1-methylbutylamino)-5,8-dimethoxyquinoline (1a) were synthesized with the aim of studying the influence of an increased lipophilicity on the biological activity. 17a--z are active against P. vinckei (mouse), but none of these derivatives is superior to the 2,4-dimethyl derivative 1d. Flat molecules (e.g. 17k and 17e) and their bulky hydrogenated derivatives (17I and 17f) show a comparable activity. This indicates that a flat structure is not essential for the activity of the 6-aminoquinolines.
