    Mechanism of chloroquine on lysosome


    Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. This medication is used to kill the malaria parasites living inside red blood cells.

    Oct 01, 2018 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 enzymes by its interaction with DNA. Although the precise mechanism underlying the antimalarial effects of chloroquine remains unknown, chloroquine seems to exert its effects through the weak-base lysosome-tropic feature. When chloroquine enters the lysosome, it becomes protonated because of the low pH within the lysosome, and accumulation of the protonated form of chloroquine. Chloroquine has a long history of human use and is currently being tested as a sensitizing agent for certain cancers, making understanding its mechanisms of action both topical and important. Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped.

    Both drugs may be needed for a complete cure and to prevent the return of infection (relapse). In some cases, you may need to take a different medication (such as primaquine) to kill the malaria parasites living in other body tissues.

    Sep 15, 2013 Accumulation of chloroquine in the lysosome inhibits phospholipase A2. It has recently been shown that antagonists of cytoplasmic phospholipase A2 inhibit multiple endocytic pathways 42. In this case, chloroquine could be maintaining BMPR-II at the cell surface via another mechanism other than lysosomal inhibition. The effect peaks after 1-2 hours of ingestion, and it has a terminal elimination half-life of 1-2 months since it is stored and trapped in lysosomes. Mechanism The exact mechanism of chloroquine is unknown but there are many postulated theories. An important component of red blood cells, heme, is broken down by parasites. Chloroquine resistance is associated with a decrease in the amount of chloroquine that accumulates in the food vacuole, the site of action for chloroquine. The mechanism for this decreased accumulation is controversial. Some studies have shown that the decrease in drug accumulation is due to an increase in drug efflux.
