    Chloroquine endocytosis inhibitor

    Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

    Chemical treatment of cells with an endosomal trafficking inhibitor that blocks endosome progression, bafilomycin A1, resulted in a significant decrease in eTE. However, treatment of cells with lysosomotropic agents chloroquine and ammonium chloride had little effects on eTE. For non-specific adsorptive endocytosis and of anti-plasma membrane IgG specific IgG, a specific ligand of cell-surface antigens. At 4"C, methylamine and chloroquine inhibit the binding of control IgG to the cell surface, probably by a reversible competition. These two drugs, methylamine more than chloroquine, considerably slow down the rate 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.

    The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

    Endocytosis following binding to integrin heterodimers can occur by several endocytic pathways, the most intensively studied of which is clathrin-mediated endocytosis. Clathrin-mediated endocytosis is a process by which ligand-receptor binding at the plasma membrane results in receptor clustering and coated pit formation. To inhibit different forms of endocytosis. Typically, both non-specific and specific chemical inhibitors of endocytosis are tried in order to “classify” entry of a new plasma membrane protein into one of the various types of endocytosis. This classification can be confirmed through genetic approaches of protein depletion Amines such as phenothiazines, MDC and chloroquine inhibit clathrin-dependent endocytosis by affecting the function of clathrin and clathrin-coated vesicles Salisbury et al. 1980; Wang et al. 1993. Monensin is a monovalent ionophore that inhibits clathrin-dependent endocytosis by dissipating a proton gradient Dickson et al. 1982.

    WHO Model Prescribing Information Drugs Used in Parasitic. Injection 50 mg, 100 mg base as phosphate or sulfate per ml in 2-ml ampoule chloroquine base 150 mg is equivalent to chloroquine sulfate 200 mg or Chloroquine phosphate 250 mg General information Policy regarding the use of this drug as an antimalarial must be determined nationally since in many areas P. falciparum is now resistant to chloroquine.
