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. Hydroxychloroquine toxicity autofluorescence Do mucinex and plaquenil interact together Chloroquine aralen is effective in treating the what stage Lysosomotropic agents 2497 As a result of this, preferential uptake by certain cells is the rule rather than the exception for materials entering by the endocytic route. A special and particularly interesting form of endocytosis is that described in Fig. 1 as piggyback endocytosis. 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 is a lysosomotropic agent that prevents endosomal acidification 1. It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic pH, and prevents fusion of endosomes and lysosomes. 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).

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.

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. Previous reports have shown that PI3K pathway inhibitors, combined with chloroquine or other lysosomotropic agents, increased cell death in breast or glioma cell lines. In our study, we have shown that 3 different inhibitors Baf A, 3-MA, or chloroquine blocking autophagy at different stages of this process sensitize prostate tumor cells to. Because of the role of lysosomes in some forms of intracellular collagen degradation 6, the effects of the lysosomotropic agents chloroquine and ammonium chloride were evaluated using isolated embryonic chick tendon cells in suspension culture 7. These cells devote approximately 250 of their total protein production to collagen 7,8.
