    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.

    The alkalinizing lysosomotropic drugs chloroquine, hydroxychloroquine, amodiaquine, and azithromycin had a similar effect on the overall production of mature bioactive TGFβ. Reduced levels of secreted TGFβ were also associated with a decrease in Smad2 signaling. Mice treated with chloroquine showed a decrease in bronchoalveolar lavage fluid TGFβ. 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. Chloroquine is a lysosomotropic agent that causes marked changes in intracellular protein processing and trafficking and extensive autophagic vacuole formation. Chloroquine may be cytotoxic and has been used as a model of lysosomal-dependent cell death.

    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).

    Chloroquine CQ or its derivative hydroxychloroquine HCQ has been widely tested in preclinical cancer models as an inhibitor of the autophagy–lysosomal pathway. 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. DNA degradation can be inhibited either by inactivating the lysosomal enzymes or obliterating endosome fusion to lysosomes using lysosomotropic agents. We report here the effects of individual lysosomotropic agents such as chloroquine, polyvinylpyrolidone PVP and sucrose on β-gal expression in cultured fibroblasts COS, 293 and CHO.

    500 mg chloroquine phosphate (300 mg base) orally on the same day each week Comments: -If possible, suppressive therapy should start 2 weeks prior to exposure; if unable to start 2 weeks before exposure, an initial loading dose of 1 g chloroquine phosphate (600 mg base) may be taken orally in 2 divided doses, 6 hours apart.

  8. Skin Sarcoidosis - when to start hydroxychloroquine. I have good luck with hydroxychloroquine and skin lesions. It also helps with joint pain, I notice it particularly in my hands. If this is something you decide to go ahead with, it takes months before you may begin to see results, whereas the injections or systemic prednisone works fast.
