[Antimalarial 6-aminoquinolines XV. 6- and 4-aminoquinolines with a tertiary basic alkylated amino group]

Antimalarial 6-aminoquinolines (1a-c) were acylated (3a-c, 5a) and alkylated (4a-c, 6a) at the secondary aromatic 6-amino group with the aim of studying the influence of a tertiary aromatic 6-amino group on antimalarial activity and toxicity. 4 derivatives (9e-g) of 4-amino-7-chloroquinoline with a tertiary aromatic 4-amino group were synthesized to study the influence of such a variation on the biological activity of the 4-aminoquinolines. The N-alkylated derivatives 4a-c, 6a, 9f-g were active against malaria (P. vinckei/mice).
