Abstract (EN):
The synthesis and antimalarial properties of twelve new chlorinated 9H-xanthones, carrying a [2(di ethylamino)ethyl] amino group in position 1, are reported. All compounds were found to be active towards the chloroquine-susceptible and chloroquine-resistant strains 3D7 and Dd2, resp., of the protozoa parasite Plasmodium falciparum. Especially one compound, 6-chloro-1-{[2-(diethylamino)-ethyl]ami no}-9H-xanthen-9-one (1k), was found to exhibit significant in vitro activity (IC50=3.9 mu M) towards the resistant Dd2 strain.
