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. Does hydroxychloroquine affect immune system Can hydroxychloroquine affect memory Lysosomotropic agents such as Chloroquine and NH 4 Cl, have been used to demonstrate the pH sensitivity of virus entry. We therefore tested the infectivity of HCVpp after treatment of target cells with different concentrations of Chloroquine and NH 4 Cl. 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 Title = "Lysosomotropic agents induce morphological and functional changes in human muscle cells in vitro.", abstract = "We studied the distribution of lysosomes in differentiating human muscle cells in culture treated with propranolol, leupeptin and chloroquine. 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). Lysosomotropic agent chloroquine which Chloroquine - Wikipedia, Lysosomotropic agents impact on lysosomal membrane. Plaquenil for ovarian cancer CQ sensitises cells to a range of cellular stressors. CQ use in breast cancer has shown promise, but the full potential remained unclear. 9, 14, 26, 29 As such, we explored combinations of CQ with. Lysosomotropism depends on glucose a chloroquine.. Lysosomotropic agents induce morphological and functional.. Blocked Autophagy Using Lysosomotropic Agents Sensitizes.. 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. Chloroquine CQ is a lysosomotropic agent with an extensive range of biological effects 1. Historically known for its anti-malarial activity, chloroquine is a widely used biological research tool for studying autophagy inhibition. Research studies demonstrate that chloroquine accumulates in acidic lysosomes and increases the lysosomal pH. 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.
