The effect of 16 alpha-acetoxy-26-hydroxycholest-4-ene-3,22-dione (SN-1) isolated from Solanum nudum Dunal (a Solanaceae traditionally used for treating fever in Colombia) on Plasmodium falciparum erythrocyte stages and its in vitro antiplasmodial activity when combined with the following conventional drugs was studied: chloroquine (CQ), amodiaquine (AQ), desethylamodiaquine (desethyl-AQ), quinine (QN), artemisinin (AR), atovaquone (ATV) and quinine (QN). It was found that SN-1 targeted trophozoites and had a synergistic effect when combined with CQ and QN; however, it had an antagonist effect when used with the other combinations.
