    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.

    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. 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. Protein synthesis in situ by chloroquine in the culture, the parasite eukaryotic initiation factor 2a- eIF-2a is phospho- rylated in the parasite lysate to a greater extent than that observed in the control culture.

    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.

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. Chloroquine might be getting new life as an antiviral treatment for the novel coronavirus that emerged in Wuhan, China in late 2019 and has infected some 25,000 people in more than 25 countries. For decades, the drug was a front-line treatment and prophylactic for malaria.
