    Chloroquine lysing the endosome


    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.

    Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation 4. Inhibitors of endosome acidification such as chloroquine block the viral permeabilization event in endosome Stuart and Brown 2006. Treatment with chloroquine significantly reduces the replication of caliciviruses including porcine enteric calicivirus, murine norovirus‐1 and feline calicivirus in vitro Shivanna et al. 2014. Borna disease.

    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.

  7. Drug release from liposomes in the endosome-lysosomal organelles into cytoplasm is critical to cytotoxicity and anticancer effects. Chloroquine is a lysosomotropic agent that has been reported to enhance in vitro cytotoxicity of basic anticancer drugs. To investigate the mechanism of chloroquine triggering basic anticancer drugs release from liposomes and the potential to treat solid tumors in clinic, daunorubicin was loaded into folate-targeted liposomes by ammonium sulfate remote loading.

    The TLR pathway is then activated, and IFN-α is secreted by these activated pDCs. As chloroquine could potentially inhibit the acidification of the endosome, where the most important steps in pDC activation occurs, it might have potential uses as an anti-AIDS drug by acting to inhibit immune activation and slow disease progression. Aug 13, 2012 Chloroquine could disrupt the endosomal TLR pathway by inhibiting the acidification of the endosome, which is crucial for pDC activation and subsequent IFN-α secretion. 10 Consequently, it is. Since chloroquine inhibited SARS-CoV infection when added before or after infection, we hypothesized that another common lysosomotropic agent, NH 4 Cl, might also function in a similar manner. Ammonium chloride has been widely used in studies addressing endosome-mediated virus entry.
