    It accumulates inside the acidic parts of the cell, including endosomes and lysosomes. This accumulation leads to inhibition of lysosomal enzymes that require an acidic p H, and prevents fusion of endosomes and lysosomes. TLR7/8-Mediated Activation of Human NK Cells Results in Accessory Cell-Dependent IFN- Production.

    Chloroquine concentrates in the food vacuole up to 1000-fold. Chloroquine, exists in unprotonated form, CQ, monoprotonated form, CQ + and diprotonated form, CQ ++ form 13. Unprotonated form of chloroquine is membrane permeable and it freely diffuses into the red blood cell. It then continues to diffuse into the DV. The IC50 value for the chloroquine-sensitive NF54 strain was 97 μΜ and 501 µM for the R strain. Monitoring polyamine pools after treatment with dicyclohexylamine leads to a significant decrease in the intracellular spermidine content, which was nearly reversed by supplementation with spermidine. Phytochemical analysis of the extracts revealed the presence of saponins, tannins, flavonoids, alkaloids and cardiac glycocides. Fagaramide isolated from Z. chalybeum had a higher activity IC50 2.85µg/mL against the chloroquine-resistant strain than against the chloroquine-senstive IC50 16.6µg/mL strain used in the study.

    Moreover, Chloroquine inhibits autophagy as it raises the lysosomal p H, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation [4]. Chloroquine is commonly used to study the role of endosomal acidification in cellular processes [2, 3], such as the signaling of intracellular TLRs.

    The compounds were screened in vitro against the HM1 IMSS strain of Entamoeba histolytica and NF54 chloroquine-sensitive strain of Plasmodium falciparum. Among the synthesized compounds six exhibited promising antiamoebic activity with IC50 values 0.14-1.26μM lower than the standard drug metronidazole IC50 1.80μM. Strains against chloroquine as indicated by IC50's of HI 0.0365 /lID and NF54 0.183 /lID, as booth were originally chloroquine sensitive, may be due to the number of passages in vitro undergone by the parasite' line cultures at the time of experiment. Experiments on NF54 strain were carried out after more passages 394 Med J Malaysia Vel 52 Ne The IC50 value for the chloroquine-sensitive NF54 strain was 97 microM and 501 microM for the R strain. Monitoring polyamine pools after treatment with dicyclohexylamine leads to a significant decrease in the intracellular spermidine content, which was nearly reversed by supplementation with spermidine. Since spermidine is an important.

    Hydroxychloroquine-induced cardiomyopathy and heart. Introduction. Hydroxychloroquine HCQ is one of the antimalarial drugs that have been used for decades to treat rheumatic diseases. Retinal toxicity, neuromyopathy, and cardiac toxicity are recognized toxicities following prolonged use. HCQ-induced cardiomyopathy is one of the rare but severe complications which could be reversible with early withdrawal of the drug.
