Thompson, Department of Cancer Biology, Abramson Family Cancer Research Institute, 421 Curie Boulevard, 450 BRB II/III, Philadelphia, Pennsylvania 19104, USA. Chloroquine is a lysosomotropic agent that prevents endosomal acidification [1].

    Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. It is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. It is taken by mouth. Common side effects include muscle problems, loss of appetite, diarrhea, and skin rash. Serious Aug 26, 2018 Chloroquine CQ, a known autophagy inhibitor, disrupts lysosomal function by increasing lysosomal pH, thereby causing acidification, which, in turn, inhibits autophagy. The lung cancer cells were pretreated with CQ to determine whether AZD9291 induced an autophagic flux. On the other hand, the very effect of chloroquine to inhibit autophagy could also sensitize kidney cells to chemotherapy, leading to acute kidney injury. Consistent with this notion, chloroquine-treated mice 60 mg/kg, daily are more vulnerable to kidney injury from ischemic–reperfusion injury than vehicle-treated mcie. This study may indicate possible additional effect of chloroquine in chemotherapy-induced kidney injury.

    This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes. TLR7/8-Mediated Activation of Human NK Cells Results in Accessory Cell-Dependent IFN- Production. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes.

  5. 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.

    Damaged proteins and organelles accumulate in aged organs. We have previously reported that cardiac-specific Atg5 autophagy-related gene 5-deficient mice, in which the gene was floxed out early in embryogenesis, were born normally, and showed normal cardiac function and structure up to 10 weeks old. Autophagy is a key pathway in the development of endocrine resistance in breast cancer, and targeting autophagy can reverse antiestrogen resistance. Chloroquine, an antimalarial drug, inhibits autophagy by preventing degradation of autolysosomes. Chloroquine diphosphate is an antimalarial and anti-inflammatory drug widely used to treat malaria and rheumatoid arthritis. Chloroquine diphosphate is an inhibitor of autophagy and toll-like receptors TLRs.
