    Chloroquine autophagy mechanism


    Pharmacological modulators of this pathway have been extensively utilized in a wide range of basic research and pre-clinical studies. Bafilomycin A1 and chloroquine are commonly used compounds that inhibit autophagy by targeting the lysosomes but through distinct mechanisms.

    Jul 11, 2018 In the present study, the cytotoxic mechanism underlying the autophagy inhibitor CQ in cholangiocarcinoma QBC939 cells was elucidated through in vitro experiments. ER stress and autophagy inhibition occur during the stimulation of cells by CQ, resulting in intrinsic, extrinsic and autophagy-dependent apoptosis. Hydroxychloroquine and chloroquine are antimalarial drugs commonly used for the treatment of rheumatic diseases. Multiple mechanisms might explain the efficacy and adverse effects of these drugs. Autophagy is an adaptive survival mechanism that recycles amino acids through degradation of damaged organelles and macromolecules under conditions of cellular stress, such as nutrient deprivation or caloric restriction. 1 In mammal cells, autophagy is a multistep process starting with an initiation and a nucleation step in which there is a de.

    To address this, we cultured primary rat cortical neurons from E18 embryos and used the Seahorse XF96 analyzer and a targeted metabolomics approach to measure the effects of bafilomycin A1 and chloroquine on bioenergetics and metabolism. Since it is now clear that mitochondrial quality control, particularly in neurons, is dependent on autophagy, it is important to determine whether these compounds modify cellular bioenergetics.

    Autophagy is a process by which a cell breaks down macromolecules in response to starvation or stress signals. While it is closely linked with apoptosis, autophagy is primarily characterized as a catabolic mechanism by which cellular energy homeostasis is maintained, and by which cellular organelles and proteins are degraded. Autophagy is a homeostatic cellular recycling system that is responsible for degrading damaged or unnecessary cellular organelles and proteins. Cancer cells are thought to use autophagy as a source of energy in the unfavorable metastatic environment, and a number of clinical trials are now revealing the promising role of chloroquine, an autophagy inhibitor, as a novel antitumor drug. On the. The antimalarial drug chloroquine CQ disrupts autophagy by inhibiting the acidification of the lysosomes that fuse with the autophagosomes, thereby preventing the degradation of metabolic stress products and inducing apoptosis. Chloroquine-mediated inhibition of autophagy has been demonstrated in melanoma.

    Chapter 33 Antivirals, Antimalarials, and Anthelmintics. For malaria prophylaxis, chloroquine is given 500 mg/dose weekly for 2 weeks prior to travel and then weekly until 6 to 8 weeks after exposure. The dosing schedule of 1000 mg once, followed by 500 mg in 6, 24, and 48 hours is used to treat acute malaria. 10. A patient is taking chloroquine Aralen to treat acute malaria.
