    Chloroquine endosomal acidification inhibitor


    The autophagic process is also used to remove intracellular microbial pathogens. Several signaling pathways sense different types of cell stress, ranging from nutrient deprivation to microbial invasion, and converge to regulate autophagy at multiple stages of the process.

    Mar 11, 2002 Inhibitors of endosomal acidification fall into three groups based on their modes of action. The first class of agents is made up of the lysosomotropic weak bases, such as chloroquine, amantadine, and ammonium chloride, which diffuse across membranes in a concentration-dependent manner. Chloroquine is a weak base which can partition into acidic vesicles such as endosomes and lysosomes, resulting in inhibition of endosomal acidification and lysosomal enzyme activity. Because acidic pH of endosomes is a prerequisite of endosomal TLR activation, chloroquine can serve as an antagonist for endosomal TLRs. At least ten clinical trials are testing chloroquine, approved as an antimalarial and autoimmune disease drug. In vitro, the endosomal acidification fusion inhibitor blocked infection of a clinical isolate of SARS-CoV-2.

    Inhibitors of positive regulators of of the ULK complex and Beclin1 have been demonstrated to block autophagy. The primary step in inducing autophagy involves membrane nucleation, controlled by ULK complex and Beclin1.

  4. Inhibitors of positive regulators of of the ULK complex and Beclin1 have been demonstrated to block autophagy. These include inhibitors to the MAP kinases, JNK1, ERK and p38. The induction of Atg protein and LC3 proteins is required for vesicle expansion and formation. Inhibitors of the class III PI3 kinases can block autophagy.
