C. Matias et al., SYNTHESIS AND ANTIMALARIAL ACTIVITY OF NEW 4,6-DIALKOXY-PYRIDO[3,2-G]QUINOLINE AND 4,6-BIS(ALKYLTHIO)PYRIDO[3,2-G]QUINOLINE DERIVATIVES, Heterocycles, 43(8), 1996, pp. 1621-1632
A set of 4,6-dialkoxy- and 4,6-bis(alkylthio)pyrido[3,2-g]quinoline de
rivatives was prepared from 2,8,10-trimethylpyrido[3,2-g]quinoline-4,6
-dione as starting material. The latter was synthesized in a simple an
d convenient two step procedure. These compounds were tested in vitro
on chloroquinosusceptible and chloroquinoresistant strains of Plasmodi
um falciparum. Two of them possess a 50% inhibitory concentration (IC5
0) lower than 100 nM against both strains.
