    Lysosomes ph and the antimalarial action of chloroquine

    For decades, the drug was a front-line treatment and prophylactic for malaria. In a three-page paper published Tuesday in Cell Research, scientists at the Wuhan Institute of Virology’s State Key Laboratory of Virology write that both chloroquine and the antiviral remdesivir were, individually, “highly effective” at inhibiting replication of the novel coronavirus in cell culture.

    In this video, I will explain into one of the main antimalarial drug, chloroquine. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive. Somes and lysosomes such as STX17 could be used at least in cell culture experiments, pharmacological inhibition is more kinetically controllable, and is the most frequently employed strategy for both in vitro and in vivo studies. The most widely employed chemicals that inhibit the last stage of autophagy are chloroquine CQ, bafilomycin A 1 BafA The resulting slight elevation in endosomal pH in macrophages may influence the assembly and trafficking of molecules important in immune regulation. This hypothetical model of antimalarial drug action suggests methods for screening additional drugs for the ability to modulate the immune response.

    “It’s interesting in that it really lacks a lot of details but, nevertheless, if you look at the data as presented, at least in vitro, it seems like chloroquine can be used as an early-stage drug,” he said. Their drug screen evaluated five other drugs that were not effective. Though the paper is brief, John Lednicky, a professor at the University of Florida’s Emerging Pathogens Institute, found its results intriguing.

    The primary discovery at this point was chloroquine’s mechanism of action the compound readily crossed the lysosomal membrane and became protonated, causing its accumulation within the lysosome. Chloroquine’s continued sequestration caused a significant increase in the lysosome’s pH, inactivating acid hydrolase enzymes and rendering the lysosome nonfunctional 22–24. In the case of malaria, in which parasites hijack the lysosomal system within red blood cells to provide a. MALARIA parasites 1 or mammalian liver 2 suitably exposed to chloroquine rapidly form autophagic vacuoles; in the case of the parasites, these are visible under the light microscope because they contain clumps of pigment, the remains of haemoglobin digestion Fig. 1. These striking morphological changes are well known but not correspondingly well understood. Although the precise mechanism underlying the antimalarial effects of chloroquine remains unknown, chloroquine seems to exert its effects through the weak-base lysosome-tropic feature. When chloroquine enters the lysosome, it becomes protonated because of the low pH within the lysosome, and accumulation of the protonated form of chloroquine within the lysosome leads to less acidic conditions and, thereby, decreased lysosomal function.

Plaquenil probably have less side effects than the other meds you get for may have no side effects at all, probably just tiredness and dizziness for a week. Sure, read up on side effects, but I only become hypochondric if I do! If I notice something really odd, I take note and call my doc.
