    Chloroquine diphosphate salt autophagy


    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.

    Background References. Antitumor and antimetastatic activities of chloroquine diphosphate in a murine model of breast cancer. Jiang et al. Biomed. Pharmacother. 2010;9 Chloroquine potentiates the anti-cancer effect of 5-fluorouracil on colon cancer cells. Chloroquine diphosphate is an inhibitor of autophagy and toll-like receptors TLRs. Chloroquine diphosphate is an antimalarial and anti-inflammatory drug widely used to treat malaria and rheumatoid arthritis. - Mechanism of Action & Protocol. 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.

    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.

    Autophagy is a key pathway in the development of endocrine resistance in breast cancer, and targeting autophagy can reverse antiestrogen resistance. Chloroquine, an anti-malarial drug, inhibits autophagy by preventing degradation of autolysosomes. Chloroquine diphosphate salt powder or crystals, 98.5-101.0% dry basis Standard anti-malarial drug. Substrate for MRP in multidrug resistant cell line and inhibits photoaffinity labeling of MRP by quinoline-based photoactive drug IAAQ N-4-1-hydroxy-2-dibut ylaminoethylquinolin-8- yl-4-azidosalicylamide. Chloroquine diphosphate is used as an antimalarial drug and also functions to increase sensitivity of tumor cells to radiation and chemotherapy via inducing autophagy 1. Chloroquine diphosphate has been reported as an adjuvant for radiation and chemotherapy for inducing cell autophagy to anti-cancer cells proliferation or metastasis 2.
