摘要: Hypoestoxide (HE) is a diterpene isolated from Hypoestes rosea (Acanthaceae), plant indigenous to Nigeria. Previous studies demonstrated that HE exhibited potent anti-inflammatory and anti-cancer activities in well established animal models but weak vitro both the anti-inflammation screening systems. We now report similar observation vivo systems for antimalarial activity. The results indicate while exhibits relatively activity (IC(50) = 10 microM versus 0.11 chloroquine) against different strains of cultured P. falciparum parasites, dose required reduce parasitemia by 90% Plasmodium berghei-infected mice, much lower than standard antimalaria drugs (SD(90) 250 microg/kg 5mg/kg chloroquine). Furthermore, doses were more effective higher inhibiting parasite development. implications these findings are discussed.
