    Chloroquine mode of autophagy inhibition

    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.

    Inhibition of autophagy is an exciting and emerging strategy in cancer therapy. In this vein, our results describe a novel mechanism of action for TQ as an autophagy inhibitor selectively targeting glioblastoma cells. Abstract. Autophagy is a lysosome-dependent degradative process that protects cancer cells from multiple stresses. In preclinical models, autophagy inhibition with chloroquine CQ derivatives augments the efficacy of many anticancer therapies, but CQ has limited activity as a single agent. Mechanism of chloroquine, a lysosomotropic agent often used to interrogate effects of autophagy inhibition. Although chloro-quine is antiproliferative and synergizes with targeted anticancer drugs, these effects are independent of macroautophagy. Future studies are needed to identify appropriate genetic stratification

    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.

    Chloroquine inhibits autophagic flux by decreasing autophagosome., Autophagy inhibitor Lys05 has single-agent antitumor activity.

  7. 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. References. 1.

    Targeting the inhibition of autophagy in cancer patients would remove the tumor-protective properties that autophagy is believed to have established in cancer. Therapies being investigated target the lysosome portion of the autophagy process and include the medications chloroquine and hydroxychloroquine. In addition, chloroquine pre-treatment followed by taxol 10 nM treatment did not show significant toxicity towards non-carcinomas WI38 cells lung fibroblast cells. Thus autophagy inhibition by CQ pre-treatment can be used as a fruitful strategy to combat the phenomenon of paclitaxel resistance development as well as metastasis in lung cancer.

The autophagic process is also used to remove intracellular microbial pathogens.
