    Lysosomotropic agent chloroquine


    Note: based on a RGCC chemosensitivity analysis I have seen at a German clinic, Hydroxychloroquine has been effective in killing the cancer cells of 5 out 7 patients that were tested. It is one of very few available drugs that inhibits autophagy, a mechanism associated with its anticancer properties.

    Lysosomotropic agents e.g. chloroquine, accumulate preferentially in the lysosomes of cells in the body. These agents tend to have both lipophilic or amphiphilic compounds with basic moieties. Once inside the acidic environment of the lysosome, the drug becomes protonated and trapped in the organelle 2. Nov 15, 2015 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. Chloroquine has been used for decades for the treatment of malaria and rheumatoid arthritis, and has been shown to achieve some level of anti-HIV activity. Chloroquine is also known to be an inhibitor of autophagy by blocking acidification of the lysosome, preventing fusion with autophagosome and, thus, represents a clinical opportunity.

    In cancer, authophagy is the process used by cancer cells to “self-eat” in order to survive. Specifically, if authophagy is prolonged this will become a lethal process to cancer. duing chemotheraphy, radiotheraphy, etc.) authophagy is used by cancer cells to survive. However, note that Chloroquine has other properties as well that may be very well related to anti cancer mechanism, such as zinc ionophore, and others (see below the section on mechanisms).

  7. Furthermore, this report addresses a long-standing question regarding the mechanism of chloroquine, a lysosomotropic agent often used to interrogate effects of autophagy inhibition. Although chloroquine is antiproliferative and synergizes with targeted anticancer drugs, these effects are independent of macroautophagy.

    • Macroautophagy is dispensable for growth of KRAS mutant..
    • Blocked Autophagy Using Lysosomotropic Agents Sensitizes..
    • Chloroquine-Induced Neuronal Cell Death Is p53 and Bcl-2..

    Hydroxychloroquine and chloroquine have been recommended by Chinese and South Korean health authorities for the experimental treatment COVID-19. In vitro studies in cell cultures demonstrated that hydroxychloroquine was more potent than chloroquine against SARS-CoV-2. Apr 12, 2011 Lysosomotropic agents such as Chloroquine and NH 4 Cl are weak bases which have a tendency to accumulate in these compartments. Lysosomotropic agents are captured by protonation inside the lysosomes and accumulate there Figure Figure3. 3. The ratio of intra/extra lysosomal concentrations of these substances is equal to the ratio of. Mar 08, 2011 Chloroquine is a known lysosomotropic agent that increases lysosomal pH by accumulating within lysosomes as a deprotonated weak base. To study the effects of lysosomal dysfunction in ARPE-19, it was necessary to establish an in vitro model utilizing chloroquine. We determined the concentration of chloroquine that substantially changed lysosomal.

    Mixed Connective Tissue Disease MCTD - Bone, Joint, and. Mixed connective tissue disease damages the muscle fibers, so the muscles may feel weak and sore, especially in the shoulders and hips. Tasks such as lifting the arms above the shoulders, climbing stairs, and getting out of a chair can become very difficult.
