    Chloroquine autophagy inhibition


    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.

    Similar to bafilomycin, the former malaria drug chloroquine CQ is now widely used as an inhibitor of autophagy in both cell culture and in vivo. 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 7, 8, 9. Tumor cells require autophagy to remove misfolded proteins or damaged cellular organelles. SBI-0206965 was shown to suppress autophagy induced by mTOR inhibition. mTOR signaling is often hyperactive in many tumors and can drive proliferation, so mTOR inhibitors are being investigated as anticancer agents. Autophagy inhibition is a potential therapeutic strategy in cancer, but it is unknown which tumors will benefit. The BRAFV600E mutation has been identified as important in pediatric central nervous system CNS tumors and is known to affect autophagy in other tumor types. We evaluated CNS tumor cells with BRAFV600E and found that mutant but not wild-type cells display high rates of induced.

    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.

  4. Jul 11, 2018 Chloroquine CQ, which is frequently used clinically as an antimalarial agent, is a classic inhibitor of autophagy that blocks the binding of autophagosomes to lysosomes by altering the acidic environment of lysosomes, resulting in the accumulation of a large number of degraded proteins in cells.

    Another autophagy inhibitor that works in a similar way as chloroquine is bafilomycin A1. Bafilomycin block the fusion between autophagosomes and lysosomes by inhibiting vacuolar H+ ATPase. The antimalarial drug chloroquine CQ disrupts autophagy by inhibiting the acidification of the lysosomes that fuse with the autophagosomes, thereby preventing the degradation of metabolic stress products and inducing apoptosis. Chloroquine-mediated inhibition of autophagy has been demonstrated in melanoma. Chloroquine CQ is a lysosomotropic agent with an extensive range of biological effects 1. Historically known for its anti-malarial activity, chloroquine is a widely used biological research tool for studying autophagy inhibition. Research studies demonstrate that chloroquine accumulates in acidic lysosomes and increases the lysosomal pH.
