Are mefloquine and plaquenil the same Plaquenil and genetic marker How long before hydroxychloroquine starts working The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. Mechanism of action. Quinine is theorized to be toxic to the malarial pathogen, Plasmodium falciparum, by interfering with the parasite's ability to dissolve and metabolize hemoglobin. As with other quinoline antimalarial drugs, the mechanism of action of quinine has not been fully resolved. Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain.

Although the precise mechanism by which chloroquine exerts anticancer effects is unclear, 1 possible mechanism is its antiautophagic activity. Autophagy is 1 of the physiologic processes affected by chloroquine. These results suggest two possible mechanisms for the action of chloroquine in the synthesis of soluble TNF-R 1 chloroquine may inhibit shedding of TNF-R from the cell surface; or 2 chloroquine may block normal trafficking of these molecules to the cell surface, where shedding is presumed to occur. The uncharged chloroquine is the only membrane permeable form of the molecule and it freely diffuses into the erythrocyte up to the DV. In this compartment, chloroquine molecules become protonated and, since membranes are not permeable to charged species, the drug accumulates into the acidic digestive vacuole 3.
