    Chloroquine raises ph


    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.

    When chloroquine or NH 4 Cl are added after infection, these agents can rapidly raise the pH and subvert on-going fusion events between virus and endosomes, thus inhibiting the infection. In addition, the mechanism of action of NH 4 Cl and chloroquine might depend on when they were added to the cells. The estimated digestive vacuole pH varied with the concentration and pK a of the dye, ranging from ∼3.7-6.5. However, at low dye concentrations the estimated digestive vacuole pH of both the chloroquine-resistant and chloroquine-sensitive strains converged in the range 4.5-4.9. Binds to and inhibits DNA and RNA polymerase; interferes with metabolism and hemoglobin utilization by parasites; inhibits prostaglandin effects; chloroquine concentrates within parasite acid vesicles and raises internal pH resulting in inhibition of parasite growth; may involve aggregates of ferriprotoporphyrin IX acting as chloroquine receptors causing membrane damage; may also interfere with nucleoprotein synthesis

    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. 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.

    As the pH in lysosomes is optimal for lysosomal enzymes involved in hydrolysis, by increasing the pH of endosomal compartments 85, chloroquine and hydroxychloroquine might impair the maturation of. 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. As far as I know, chloroquine may accumulate in the lysosome and gradually increase lysosomal pH and impair its function.
