Because of the spread of drug-resistantPlasmodiumspecies, there is an urgent need for novel effective antimalarial agents. A series of arylene bis(methylketone) compounds were screened in vitro against a number ofPlasmodium falciparumclones and in vivo againstPlasmodium berghei. 2-amino-4-(3,5-diacetylphenyl)amino-1,6-dimethylpyrimidinium chloride (Cytokine Network Inc. [CNI]-H0294) was the most effective of the compounds in vitro, with an IC50of 1.5–4.0 µ/Magainst parasite clones with a wide range of sensitivities to chloroquine and pyrimethamine. Other compounds in the series had in vitro IC50values of 20–25 µ/M. In a 4-day test for suppression ofP. bergheiparasitemia in vivo, 50 mg/kg/day CNI-H0294 significantly decreased parasitemia by >90%. The compound was found to have low toxicity in mice, with an LD50of 590 ± 66 mg/kg intraperitoneally, and rapid plasma kinetics. These results show that CNI-H0294 has considerable antimalarial activity and merits further study.
