    Chloroquine mechanism of action autophagy


    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    The first US Food and Drug Administration FDA-approved agent capable of inhibiting autophagy was chloroquine, a drug previously used to treat malaria and arthritis, which also blocks autophagy. 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. MHY1485 has the ability to penetrate the cell. It prevents the ultraviolet-induced oxidative stress in keratinocytes and fibroblasts. MHY1485 is mTOR activator that potently inhibits autophagy by suppression of fusion between autophagosomes and lysosomes.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

  3. Autophagy is involved in the pathophysiology of numerous diseases and its modulation is beneficial for the outcome of numerous specific diseases. Several lysosomal inhibitors such as bafilomycin A1 BafA1, protease inhibitors and chloroquine CQ, have been used interchangeably to block autophagy in in vitro experiments assuming that they all primarily block lysosomal degradation.

    In parallel with these findings, another study demonstrated that autophagy is a key mechanism for anti-leukemic effects of ATO in AML cell lines and leukemic progenitors from AML patients, and this induction of autophagy flux is associated with mitogen-activated protein kinase kinase MEK/extracellular signal-regulated kinase ERK-dependent autophagic cell death. Chloroquine, autophagy and immune response Autophagy is an important cellular mechanism developed to degrade aged and dysfunctional proteins and organelles, as well as a mean to overcome lack of nutrients during starvation and it is also involved in eliminating some microorganisms. Abstract. Chloroquine is thought to exert its antimalarial effect by preventing the polymerization of toxic heme released during proteolysis of hemoglobin in the Plasmodium digestive vacuole. The mechanism of this blockade has not been established. We incubated cultured parasites with subinhibitory doses of 3Hchloroquine and 3H quinidine.
