    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.

    Such substances are referred to as lysosomotropic agents, and via this mechanism, trapped substances may accumulate to concentrations hundredfold that of the cytosolic concentration 22 Figure 1. Several well-known drugs used in the clinic have documented lysosomotropic abilities including the antimalarial drug chloroquine, several Dec 02, 2016 In this study, we aimed to investigate the influence of lysosomotropic agent, chloroquine, on the efficacy of obinutuzumab-mediated cytotoxicity. As PCD is dependent on lysosomal destabilization, we hypothesized that combination of obinutuzumab with lysosome-destabilizing agent would result in increased cell death. Apr 12, 2011 Fusion of the HCV envelope proteins is triggered by low pH within the endosome. Lysosomotropic agents LA such as Chloroquine and Ammonium chloride NH₄Cl are the weak bases and penetrate in lysosome as protonated form and increase the intracellular pH.

    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).

  6. 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 activity, but did not result in cell necrosis.

    Freshly isolated embryonic chick tendon fibroblasts were incubated in suspension culture for six hrs in the presence or absence of ammonium chloride or chloroquine. Both agents caused a marked reduction in collagen production without inhibiting non-collagen protein synthesis. 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. Treatment of cells with the macrolide antibiotic bafilomycin A1, an inhibitor of vacuolar V-ATPase, or with the lysosomotropic agent chloroquine, has been shown to pharmacologically inhibit autophagy as evidenced by an accumulation of autophagosomes, which in turn causes Bax-dependent apoptosis. However, bafilomycin A1 has also been reported to inhibit chloroquine-induced apoptosis.
