    Synthesis of chloroquine phosphate


    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.

    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. Occasionally it is used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. Sigma-Aldrich offers a number of Chloroquine phosphate products. View information & documentation regarding Chloroquine phosphate, including CAS, MSDS & more. Chloroquine is a synthetic aminoquinoline that acts by binding to the protozoal or parasitic DNA and preventing DNA and RNA production and subsequent protein synthesis; it is active against the asexual erythrocytic forms of Plasmodium and Entamoeba species.

    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.

    This gene is imprinted, with preferential expression from the maternal allele. Mutations in this gene have been found in Wilms' tumor and lung cancer. This protein may act as a transporter of organic cations, and have a role in the transport of chloroquine and quinidine-related compounds in kidney. Chloroquine phosphate exhibits essentially no optical activity, existing as a racemic mixture. Chloroquine phosphate exists in two polymorphic forms giving rise to two melting ranges. Chloroquine phosphate is freely soluble in water—practically insoluble in alcohol, in chloroform and in ether. It influences Hb digestion by increasing intravesicular pH in malaria parasite cells and interferes with the nucleoprotein synthesis of the patient. It is also effective in extra intestinal amoebiasis. In RA chloroquine and more effectively hydroxychloroquine have a -modifying effect.
