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 cause cancer Hydroxychloroquine and imodium Oct 01, 2018 Chloroquine is deposited in the tissues in considerable amounts. In animals, from 200 to 700 times the plasma concentration may be found in the liver,spleen, kidney, and lung; leukocytes also concentrate the drug. The brain and spinal cord, in contrast, contain only 10 to 30 times the amount present in plasma. Find patient medical information for Chloroquine Oral on WebMD including its uses, side effects and safety, interactions, pictures, warnings and user ratings. In addition to its p53-activating effects, chloroquine may also inhibit glioma cell growth via p53-independent mechanisms. Our results clarify the mechanistic basis underlying the antineoplastic effect of chloroquine and reveal its therapeutic potential as an adjunct to glioma chemotherapy. 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).

Glioblastoma GBM, the most common and aggressive primary brain tumor, is characterized by excessive growth and infiltration of the normal brain which prevents the complete surgical resection. These tumors also are refractory to standard treatment strategies. Chloroquine inhibits the malignant phenotype of glioblastoma.. Chloroquine activates the p53 pathway and induces apoptosis.. Anti-malaria Drug Chloroquine May Help Combat Some Brain Tumors. Because autophagy seems to contribute to promote cancer, chloroquine may sensitize cancer cells through inhibiting autophagy. The dosage of chloroquine usually ranges between 100 and 500 mg/day. Side effects are minimal at low doses, while many more toxic effects occur at higher doses, such as visual disturbances, gastrointestinal upset, electrocardiographic changes, headache, and pruritus. If chloroquine could decrease the toxicity of Tf-CRM107 without decreasing antitumor efficacy, an improved therapy for brain tumors may be possible. The BBB may be expected to limit the amount of chloroquine that can pass into the cerebral fluid, bathing brain tumor cells, and may prevent enough chloroquine from entering the brain to block the. Addition of chloroquine can improve clinical outcomes. These ﬁ ndings suggest that CNS tumors with BRAF V600E are autophagy-dependent and should be targeted with autophagy inhibition in combination with other therapeutic strategies. SIGNIFICANCE Autophagy inhibition may improve cancer therapy, but it is unclear which tumors will beneﬁ t.
