    Chloroquine lysosome acidification


    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.

    Chloroquine alkalinizes the lysosome, thus maintaining GFP fluorescence. Leupeptin A does not affect the acidic lysosomal pH, and therefore only RFP fluorescence is observed. C Monitoring autophagosome–lysosome fusion and acidification. Chloroquine enters the red blood cell, inhibiting the parasite cell and digestive vacuole by simple diffusion. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Oct 01, 2018 Excretion of Chloroquine is quite slow,but is increased by acidification of the urine. Chloroquine is deposited in the tissues in considerable amounts. In animals, from 200 to 700 times the plasma concentration may be found in the liver,spleen, kidney, and lung; leukocytes also concentrate the drug.

    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.

    Mar 11, 2002 Inhibitors of endosomal acidification fall into three groups based on their modes of action. The first class of agents is made up of the lysosomotropic weak bases, such as chloroquine, amantadine, and ammonium chloride, which diffuse across membranes in a concentration-dependent manner. It is thus not surprising that chloroquine/hydroxychloroquine is concentrated within acidic organelles such as the endosome, Golgi vesicles, and the lysosomes, where the pH is low and most chloroquine/hydroxychloroquine molecules are positively charged. Excretion of Chloroquine is quite slow,but is increased by acidification of the urine. Chloroquine is deposited in the tissues in considerable amounts. In animals, from 200 to 700 times the plasma concentration may be found in the liver,spleen, kidney, and lung; leukocytes also concentrate the drug.
