    Chloroquine is a lysosomotropic agent that prevents endosomal acidification 1. 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 pH, and prevents fusion of endosomes and lysosomes. Chloroquine is an aminoquinoline that is an inhibitor of autophagy and has antimalarial and anticancer activities. 1,2,3 Chloroquine inhibits autophagosome-lysosome fusion in HeLa cells when used at a concentration of 100 µM. 1 It is active against the chloroquine-sensitive GC03 strain of P. falciparum IC 50 = 29.2 nM but has decreased activity against mutant pfcrt P. falciparum IC 50 s. Owing to its lysosomotropic properties, CHQ accumulates primarily in the lysosome, where the increase of the lysosomal pH leads to a blockage of the lysosome-autophagosome fusion, a critical event during the late stage of autophagy. Good solubility and rapid absorption are attractive pharmacological properties of CHQ.

  4. Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped. Protonated chloroquine then changes the lysosomal pH, thereby inhibiting autophagic degradation in the lysosomes.

    Chloroquine is a known lysosomotropic agent that increases lysosomal pH by accumulating within lysosomes as a deprotonated weak base. To study the effects of lysosomal dysfunction in ARPE-19, it was necessary to establish an in vitro model utilizing chloroquine. May 11, 2015 However, V-ATPase-deficient lysosomes remain competent to fuse with autophagosomes and endosomes, resulting in a time-dependent formation of giant autolysosomes. In contrast, BafilomycinA1 prevents autophagosome–lysosome fusion in these cells, and this defect is phenocopied by depletion of the Ca 2+ pump SERCA. Because the Class C VPS complex is essential in both the endosome-lysosome and the autophagosome-lysosome fusion processes 7, 29, 30, we thus examined whether disruption of the autophagy pathway could contribute to enhanced tumor overgrowth and metastasis.

    Chloroquine-resistance transporter – NIH Director's Blog Researchers also hope that this model will allow drug designers to make structural adjustments to old, less effective malarial drugs and perhaps restore them to their former potency. Perhaps this could even be done by modifying chloroquine, introduced in the 1940s as the first effective antimalarial.
