    Chloroquine autophagy inhibitor


    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.

    Autophagy has a pro-tumorigenic role in established tumors and consequently the vast majority of clinical trials focus on autophagy inhibition in cancer. Over the last decade, a dozen Phase I and I/II clinical trials have been completed and published using the autophagy inhibitors, Chloroquine CQ or hydroxychloroquine HCQ in cancer. These lysosomal targeting compounds were originally approved for use in humans as anti-malarial drugs but have been repurposed as autophagy targeting cancer. Results Autophagy was induced in colon cancer models by exposure to both hypoxia and oxaliplatin. Inhibition of autophagy, either with chloroquine or by downregulation of beclin1 or of ATG5, enhanced sensitivity to oxaliplatin under normal and hypoxic conditions in a synergistic manner. Both bevacizumab and oxaliplatin treatments activate autophagy in HT29 murine xenografts. The addition of chloroquine to bevacizumab-based treatment provided greater tumor control in concert with evidence of. Autophagy-related proteins Fig. 1D and a resultant high degree of autophagy inhibition Supplementary Fig. S2B. Because chloroquine is a potent autophagy inhibitor that is FDA-approved and available for rapid translation to pedi-atric clinical trials, we evaluated its effects on our CNS tumor cells.

    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.

    Similar to bafilomycin, the former malaria drug chloroquine CQ is now widely used as an inhibitor of autophagy in both cell culture and in vivo. Chloroquine has a long history of human use and is currently being tested as a sensitizing agent for certain cancers, making understanding its mechanisms of action both topical and important 7, 8, 9. Inhibition of autophagy with either chloroquine or ATG5 short hairpin RNA shRNA enhanced the ability of either p53 activation or alkylating drug therapy to induce tumor cell death. These studies provide evidence that autophagy serves as a survival pathway in tumor cells treated with apoptosis activators and a rationale for the use of autophagy inhibitors such as chloroquine in combination with therapies designed to induce apoptosis in human cancers. Chloroquine has long been used in the treatment or prevention of malaria from Plasmodium vivax, P. ovale, and P. malariae, excluding the malaria parasite Plasmodium falciparum, for it started to develop widespread resistance to it.

    Chloroquine - FDA prescribing information, side effects and uses Oct 01, 2018 Mechanism of Action Chloroquine, a 4-aminoquinoline, is an anti-protozoal agent. The precise mechanism by which Chloroquine exhibits activity is not known. Chloroquine, may exert its effect against Plasmodium species by concentrating in the acid vesicles of the parasite and by inhibiting polymerization of heme. It can also inhibit certain enzymes by its interaction with DNA.
