    Is chloroquine a lysosome

    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.

    Sep 15, 2013 Inhibition of the lysosome by concanamycin A and chloroquine significantly increases endogenous expression of BMPR-II in endothelial cells. A Human PAECs were treated for 16 h with DMSO vehicle, concanamycin A 50 n m or chloroquine 100 μ m. Total BMPR-II expression was assessed by immunoblotting and reprobed for α-tubulin to ensure equal loading. Chloroquine raises the pH in host-cell lysosomes, which interferes with viruses’ attempts to acidify the lysosomes, a prerequisite to formation of the autophagosomes that cells use to eat themselves. In the Cell Research paper, the researchers found that the drug was effective at inhibiting the virus as it was both entering and exiting cells. Chloroquine, a medication used to prevent and to treat malaria, has just been confirmed as one of the three anti-viral drug for Coronavirus. The search for the cure of Coronavirus has been on for some time

    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.

  7. Chloroquine is also a lysosomotropic agent, meaning it accumulates preferentially in the lysosomes of cells in the body. The pK a for the quinoline nitrogen of chloroquine is 8.5, meaning it is about 10% deprotonated at physiological pH as calculated by the Henderson-Hasselbalch equation.

    Chloroquine is a lysosomotropic weak base, which in the monoprotonated form diffuses into the lysosome, where it becomes diprotonated and becomes trapped. Protonated chloroquine then changes the lysosomal pH, thereby inhibiting autophagic degradation in the lysosomes. Chloroquine is an established antimalarial agent that has been recently tested in clinical trials for its anticancer activity. The favorable effect of chloroquine appears to be due to its ability to sensitize cancerous cells to chemotherapy, radiation therapy, and induce apoptosis. The present study investigated the interaction of zinc ions with chloroquine in a human ovarian cancer cell line. Chloroquine is a member of quinolone family and is a weak intercalating agent. Chloroquine is used for treating amebiasis, rheumatoid arthritis, discoid and systemic lupus erythematosus. Application DNA intercalator. Also used to increase transfection efficiency. Chloroquine diphosphate salt has been used • in in vitro antiplasmodial assays
