Abstract

Systematic variation of the branching and basicity of the side chain of chloroquine yielded a series of new 7-chloro-4-aminoquinoline derivatives exhibiting high in vitro activity against four different strains of P. falciparum. Many of the compounds tested showed excellent potency against chloroquine sensitive and resistant strains. In particular 4b, 5a, 5b, 5d, 17a, and 17b were found to be significantly more potent than chloroquine against the resistant strains Dd2 and FCB.
