Dehydroabietinol在体外抑制红细胞中的氯喹敏感及氯喹抵抗型疟原虫，IC50为26-27 μM.

Dehydroabietinol inhibits growth of chloroquine-sensitive as well as chloroquine-resistant strains of Plasmodium falciparum cultivated in erythrocytes in vitro (IC 50 26-27 microM).

Dehydroabietinol isolated from Hyptis suaveolens (L.) Poit. was found to inhibit growth of chloroquine-sensitive as well as chloroquine-resistant strains of Plasmodium falciparum cultivated in erythrocytes in vitro (IC 50 26-27 microM). However, erythrocytes exposed to Dehydroabietinol were transformed in a dose-dependent manner towards spherostomatocytic forms with concomitant formation of endovesicles, as disclosed by transmission electron microscopy. The erythrocyte shape alterations caused by Dehydroabietinol correlated well with its apparent IC 50 value. CONCLUSIONS: Thus, Dehydroabietinol incorporates into the erythrocyte membrane, and since invasion and survival of Plasmodium parasites is known to depend on the function of the erythrocyte membrane, the observed antiplasmodial effect of Dehydroabietinol is presumably an indirect effect on the host cell. Because of these findings, microscopic investigations should be generally used to support claims of antimalarial effects of apolar natural products[1].
