    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.

    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. A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen. 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.

  5. 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.

    Mechanism. Endosomal Acidification Inhibitor Chloroquine is a lysosomotropic agent that prevents endosomal acidification 1. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. Hydroxychloroquine and chloroquine are antimalarial drugs commonly used for the treatment of rheumatic diseases. Aug 24, 2017 Taken together, our data indicate that CQ effectively targets the lysosome to sensitise towards cell death but is prone to a glucose-dependent resistance mechanism, thus providing rationale for.

    Chloroquine - Wikipedia Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion.
