    Inhibitors of endosome acidification such as chloroquine block the viral permeabilization event in endosome Stuart and Brown 2006. Treatment with chloroquine significantly reduces the replication of caliciviruses including porcine enteric calicivirus, murine norovirus‐1 and feline calicivirus in vitro Shivanna et al. 2014. Borna disease. Nov 29, 2016 Chloroquine inhibits acidification of the endosome, consequently inhibiting the low pH-induced conformational changes required for the fusion of the envelope protein of flaviviruses with the endosomal membrane. Usual Adult Dose for Malaria Prophylaxis. 500 mg chloroquine phosphate 300 mg base orally on the same day each week Comments-If possible, suppressive therapy should start 2 weeks prior to exposure; if unable to start 2 weeks before exposure, an initial loading dose of 1 g chloroquine phosphate 600 mg base may be taken orally in 2 divided doses, 6 hours apart.

    Approved indication: For acute attacks of malaria due to P vivax, P malariae, P ovale, and susceptible strains of P falciparum CDC Recommendations: Chloroquine-sensitive uncomplicated malaria (Plasmodium species or species not identified): 600 mg base (1 g salt) orally at once, followed by 300 mg base (500 mg salt) orally at 6, 24, and 48 hours Total dose: 1.5 g base (2.5 g salt) Comments: -For the treatment of uncomplicated malaria due to chloroquine-sensitive P vivax or P ovale, concomitant treatment with primaquine phosphate is recommended. 60 kg or more: 1 g chloroquine phosphate (600 mg base) orally as an initial dose, followed by 500 mg chloroquine phosphate (300 mg base) orally after 6 to 8 hours, then 500 mg chloroquine phosphate (300 mg base) orally once a day on the next 2 consecutive days Total dose: 2.5 g chloroquine phosphate (1.5 g base) in 3 days Less than 60 kg: First dose: 16.7 mg chloroquine phosphate/kg (10 mg base/kg) orally Second dose (6 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Third dose (24 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Fourth dose (36 hours after first dose): 8.3 mg chloroquine phosphate/kg (5 mg base/kg) orally Total dose: 41.7 mg chloroquine phosphate/kg (25 mg base/kg) in 3 days Comments: -Concomitant therapy with an 8-aminoquinoline compound is necessary for radical cure of malaria due to P vivax and P malariae.

    Apr 09, 2018 Key Difference – Endosome vs Lysosome. The key difference between the Endosome and the Lysosome is based upon its formation and its function in the cell. Endosome is formed by endocytosis, whereas the lysosome is a membrane bound vesicle containing degrading hydrolytic enzymes. Chloroquine is a medication used to prevent and to treat malaria in areas where malaria is known to be sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. It is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. It is taken by mouth. Common side effects include muscle problems, loss of appetite, diarrhea, and skin rash. Serious Dec 22, 2006 To examine the effect of chloroquine treatment on endocytic pathway compartments, we performed Western blotting of lysates of the cells, which had been treated with 1 μM chloroquine for 5 days, using antibodies specific to Rab5, Rab7 and Rab4, which are proteins specifically associated with early endosomes, late endosomes and recycling vesicles, respectively.

    Hydroxychloroquine sulfate C18H28ClN3O5S - PubChem Hydroxychloroquine Sulfate is a synthetic derivative of quinolyl with chemotherapeutic and antibiotic properties, Hydroxychloroquine Sulfate acts against erythrocytic malarial parasites Plasmodium vivax, ovale, and malariae by concentrating in food vacuoles. It inhibits plasmodial heme polymerase and acts through other unknown mechanisms.
