    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. 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. Rationales for lysosomotropic amines. Chloroquine is a diprotic weak base pK a1 = 8.1, pK a2 = 10.2 at 37°C that can exist in both protonated and unprotonated forms Figure 2 and Table 2. Unprotonated chloroquine can diffuse freely and rapidly across the membranes of cells and organelles to acidic cytoplasmic vesicles late endosomes and.

    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).

    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 Chloroquine CQ or its derivative hydroxychloroquine HCQ has been widely tested in preclinical cancer models as an inhibitor of the autophagy–lysosomal pathway. Haploid cells of opposite mating type of Saccharomyces cerevisiae conjugate to form zygote. During the conjugation process, the degradation or reorganization of the cell wall and the fusion of the two plasma membranes take place. Since chloroquine inhibits cellular events associated with the reorganization of the plasma membrane, the effect of the drug on conjugation was studied. Chloroquine.
