Anti-Plasmodium falciparum activity of quinoline–sulfonamide hybrids
2015
Fifteen quinoline–sulfonamide hybrids, with a 7-chloroquinoline moiety connected by a linker group to arylsulfonamide moieties with different substituents in the 4-position were synthesized and assayed against Plasmodium falciparum. The compounds displayed high schizonticidal blood activity in vitro, with IC 50 values ranging from 0.05 to 1.63 l M, in the anti-HPR2 assay against clone W2-chloroquine-resistant; ten of them showed an IC 50 (ranging from 0.05 to 0.40 l M) lower than that of chloroquine and sulfadoxine. Among them, two compounds inhibited Plasmodium berghei parasitemia by 47% and 49% on day 5 after mice inoculation. The most active, in vivo, hybrid 13 is considered to be a new prototype for the development of an antimalarial drug against chloroquine-resistant parasites
