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. Chloroquine ic 50 Chloroquine phosphate show up on drug test Chloroquine phosphate chemical structure Furthermore, this report addresses a long-standing question regarding the mechanism of chloroquine, a lysosomotropic agent often used to interrogate effects of autophagy inhibition. Although chloroquine is antiproliferative and synergizes with targeted anticancer drugs, these effects are independent of macroautophagy. Hydroxychloroquine and chloroquine have been recommended by Chinese and South Korean health authorities for the experimental treatment COVID-19. In vitro studies in cell cultures demonstrated that hydroxychloroquine was more potent than chloroquine against SARS-CoV-2. Chloroquine CQ or its derivative hydroxychloroquine HCQ has been widely tested in preclinical cancer models as an inhibitor of the autophagy–lysosomal pathway. 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 is a lysosomotropic agent, which has been extensively used as an antimalarial drug in the past, before parasite resistance started to limit its efficacy in. Chloroquine Interference with Hemoglobin Endocytic.. Lysosomotropism depends on glucose a chloroquine.. RESEARCH Open Access Chloroquine treatment of ARPE-19 cells.. 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. 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. Dec 02, 2016 In this study, we aimed to investigate the influence of lysosomotropic agent, chloroquine, on the efficacy of obinutuzumab-mediated cytotoxicity. As PCD is dependent on lysosomal destabilization, we hypothesized that combination of obinutuzumab with lysosome-destabilizing agent would result in increased cell death.
