[en] Eight naturally occurring anhydronium bases and the synthetic quaternary compound Nb-methylharmalane were tested against Plasmodium falciparun (strain K1) in vitro. Cryptolepine was found to have similar activity to that of chloroquine but alstonine, 5,6-dihydroflavopereirine, matadine, Nb-methylharmalane, melinonine F, normelinonine F, strychnoxanthine and serpentine were found to have little activity. Cryptolepine, given orally to mice infected with Plasmodium berghei berghei was found to have moderate antimalarial activity; parasitemia was suppressed by 80% at 50 mg/kg/day.
