    Chloroquine mechanism of action lysosome


    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 p H, and prevents fusion of endosomes and lysosomes.

    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. The combination of chloroquine with zinc enhanced chloroquine's cytotoxicity and induced apoptosis in A2780 cells. Thus chloroquine is a zinc ionophore, a property that may contribute to chloroquine's anticancer activity. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic FP-chloroquine and FP results in cell lysis and ultimately parasite cell autodigestion. In essence, the parasite cell drowns in its own metabolic products.

    Moreover, Chloroquine inhibits autophagy as it raises the lysosomal p H, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4]. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.

    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. Although these drugs are known to accumulate by a weak base mechanism in the acidic food vacuoles of intraerythrocytic trophozoites and thereby prevent hemoglobin degradation from occuring in that organelle, the mechanism by which their selective toxicity for lysosomes of malaria trophozoites is achieved has been subject to much discussion and argument. The primary discovery at this point was chloroquine’s mechanism of action the compound readily crossed the lysosomal membrane and became protonated, causing its accumulation within the lysosome.

    Treating Lupus with Anti-Malarial Drugs Johns Hopkins. Three anti-malarial drugs are prescribed for lupus symptoms. Hydroxychloroquine Plaquenil is the most commonly prescribed because it is generally believed to cause fewer side effects; chloroquine Aralen has a reputation for more serious side effects, but it may be prescribed in situations where hydroxychloroquine cannot be used.
