title: Synthesis of 2-[3-(7-Chloro-quinolin-4-ylamino)-alkyl]-1-(substituted phenyl)-2,3,4,9-tetrahydro-1H-beta-carbolines as a new class of antimalarial agents.
abstract: A series of hybrid molecules 2-[3-(7-Chloro-quinolin-4-ylamino)-alkyl]-1-(substituted phenyl)-2,3,4,9-tetrahydro-1H-beta-carbolines have been synthesized and screened for their in vitro antimalarial activity against chloroquine-sensitive strains of Plasmodium falciparum. Compounds 26, 32, and 34 have shown MIC in the range of 0.05-0.11 microM and are in vitro several folds more active than chloroquine.
