Mechanism of Action

Mefloquine, like chloroquine and quinine, is a blood schizonticidal agent and is active against the intraerythrocytic stages of parasite development. Similar to chloroquine and quinine, mefloquine appears to interfere with the parasite's ability to metabolize and utilize erythrocyte hemoglobin. The antimalarial activity of mefloquine may depend on the ability of the drug to form hydrogen bonds with cellular constituents; results of structure-activity studies indicate that the orientation of the hydroxyl and amine groups with respect to each other in the mefloquine molecule may be essential for antimalarial activity. While the precise mechanism of action of mefloquine is unknown, it may involve mechanisms that differ from those proposed for chloroquine., The effects of the antimalarial drug, mefloquine, on the uptake and release of Ca2+ by crude microsomes from dog brain were investigated using a spectrophotometric method. Mefloquine inhibited the inositol-1,4,5-phosphate (IP3)-induced Ca2+ release with an IC50 of 42 uM, but was a weaker inhibitor of the uptake of Ca2+ into the vesicles (IC50: 272 uM). These effects of mefloquine are in contrast to its actions on Ca2+ uptake and release by skeletal muscle microsomes, where its predominant effect was seen to be the inhibition of Ca2+ uptake into the vesicles. Mefloquine was found to be more potent than quinine as a specific inhibitor of Ca2+ release from IP3-sensitive stores in dog brain microsomes. The possibility of the drug affecting cellular IP3-linked signal transduction processes should be considered.
