    Chloroquine raises the pH in host-cell lysosomes, which interferes with viruses’ attempts to acidify the lysosomes, a prerequisite to formation of the autophagosomes that cells use to eat themselves. In the Cell Research paper, the researchers found that the drug was effective at inhibiting the virus as it was both entering and exiting cells.

This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs.

  4. Chloroquine is also a lysosomotropic agent, meaning it accumulates preferentially in the lysosomes of cells in the body. The pK a for the quinoline nitrogen of chloroquine is 8.5, meaning it is about 10% deprotonated at physiological pH as calculated by the Henderson-Hasselbalch equation. This decreases to about 0.2% at a lysosomal pH of 4.6.

    From these findings, we infer that chloroquine caused the disruption of lysosomes in the living cells, and that lysosomes treated with chloroquine were easily disrupted by homogenization or. CQ is a weak base and therefore it can raise the pH of cellular compartments. This has led to the assumption that CQ blocks the autophagic flux through the same mechanism as BafA 1, which increases lysosomal pH and thus inhibits the activity of resident hydrolases 14 – 16. 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 the generic form of the brand-name prescription medicine Aralen, which is used to prevent and treat malaria — a mosquito-borne disease caused by a parasite — and to treat amebiasis, an infection of the intestines caused by a parasite.

    Aralen Chloroquine Uses, Dosage, Side Effects, Interactions, Warning Before using chloroquine for prophylaxis, it should be ascertained whether chloroquine is appropriate for use in the region to be visited by the traveler. Chloroquine should not be used for treatment of P. falciparum infections acquired in areas of chloroquine resistance or malaria occurring in patients where chloroquine prophylaxis has failed.
