    Chloroquine phosphate synthesis


    Visit Stack Exchange My intuition tells me that the nitrogen in the ring is more nucleophilic than the exocyclic amine. All this is not very promising and any attempt to optimize this reaction is fighting problems you would not have if you had decided for a more reasonable and well-established alternative in the first! A quick-and-dirty electrostatic potential calculation using B88LYP/6-31G(d) on the PM3 geometry shows a large electron density (blue and violet) on the ring nitrogen and lower density (yellow) on the exocyclic amine: Are there conditions that might work? That would be the synthesis of chloroquine from 4,7-dichloroquinoline and 4-diethylamino-1-methylbutylamine, where both starting materials are available through well-known procedures.

    Note 250 mg of chloroquine phosphate is equivalent to 150 mg of chloroquine base. Chloroquine dose for the chemoprophylaxis of malaria 500 mg of chloroquine phosphate 300 mg base once a week on the same day each week. Initiate treatment one to two weeks before entering the endemic area and continue for four weeks after leaving it. Mar 22, 2018 [email protected] This feature is not available right now. Please try again later. Chloroquine phosphate is freely soluble in water—practically insoluble in alcohol, in chloroform and in ether. Two polymorphic forms of chloroquine phosphate are exhibited by differential scanning calorimetry DSC. A mixture of the two crystal forms may be demonstrated also by the transition temperatures.

    It's a pretty untypical approach to chloroquine and you didn't tell how you would synthesize 7-chloro-3-aminoquinoline and the secondary chloride. There is a good chance that the planned reaction will furnish a quarternary ammonium salt as a side product: The reaction will not necessary stop at this point.

  5. Chloroquine, introduced into medicine in the 1940s, is a member of an important series of chemically related antimalarial agents, the quinoline derivatives. Chloroquine is administered orally as chloroquine phosphate. It also can be given by intramuscular injection as chloroquine hydrochloride.

    Each tablet contains 500 mg of Chloroquine phosphate USP, equivalent to 300 mg Chloroquine base. Inactive Ingredients colloidal silicon dioxide, dibasic calcium phosphate, hydroxypropylmethylcellulose, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polysorbate80, pregelatinized starch. 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 then becomes protonated to CQ2+, as the digestive vacuole is known to be acidic pH 4.7; chloroquine then cannot leave by diffusion. Chloroquine caps hemozoin molecules to prevent further biocrystallization of heme, thus leading to heme buildup. Chloroquine binds to heme or FP to form the FP-chloroquine complex; this complex is.
