    Each drug entry includes links to check for clinical trials listed in NCI's List of Cancer Clinical Trials. A 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities.

    Since most of the tumor cells survive on autophagy mechanism, inhibition of autophagy inducers Unc-51 serine/threonine-protein kinase-like autophagy activating kinase ULK1 and ULK2 might be useful in cancer therapy. Nov 15, 2015 Indeed, current clinical trials are trying to use chloroquine or hydroxychloroquine, alone or in combination with other drugs to inhibit autophagy during breast cancer therapy since chemotherapy and radiation, regimens that are used to treat breast cancer, are known to induce autophagy in cancer cells. Aug 23, 2018 Autophagy is receiving a lot of attention for the role it may play in preventing or treating cancer, too. “Autophagy declines as we age, so this means cells that no longer work or may do harm.

    This agent may also interfere with the biosynthesis of nucleic acids. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite.

  5. Chloroquine enters the red blood cell by simple diffusion, inhibiting the parasite cell and digestive vacuole. Chloroquine then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion.

    Chloroquine's potential chemosensitizing and radiosensitizing activities in cancer may be related to its inhibition of autophagy, a cellular mechanism involving lysosomal degradation that minimizes the production of reactive oxygen species ROS related to tumor reoxygenation and tumor exposure to chemotherapeutic agents and radiation. In the last two decades, accumulating evidence pointed to the importance of autophagy in various human diseases. As an essential evolutionary catabolic process of cytoplasmatic component digestion, it is generally believed that modulating autophagic activity, through targeting specific regulatory actors in the core autophagy machinery, may impact disease processes. Both autophagy upregulation. Autophagy is a homeostatic, catabolic degradation process whereby cellular proteins and organelles are engulfed by autophagosomes, digested in lysosomes, and recycled to sustain cellular metabolism. Autophagy has dual roles in cancer, acting as both a tumor suppressor by preventing the accumulation of damaged proteins and organelles and as a mechanism of cell survival that can promote the.
