    Synthesis of chloroquine from m-chloroaniline


    Chloroquine phosphate is a white, odorless, crystalline powder having a bitter taste: it discolors gradually on exposure to light. The fluorescence spectrum of chloroquine phosphate obtained on a solution of 0.2 mg/ml p H 7.9 phosphate buffers using an Aminco–Bowman spectrophotofluorometer.

    Synthesis of AQ analogues. AQ analogues were synthesized as described previously 9–12. Briefly, as an example, 7-chloro-AQs were synthesized by the condensation of m-chloroaniline with ethyl ethoxymethylene malonate to produce 4,7-dichloroquinoline. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite. Chloroquine-resistance malaria species. This thesis describes research targeted at the modification of lead reversed chloroquine molecules to discover new and effective moieties, as well as to improve pharmacokinetic-related properties. An especial emphasis of this project is the addition of a sulfonamide functional group to a reversed chloroquine.

    Chloroquine phosphate exists in two polymorphic forms giving rise to two melting ranges. Chloroquine phosphate exhibits essentially no optical activity, existing as a racemic mixture.

  3. Anti‐malaria drugs chloroquine and amodiaquine and their metabolites were synthesized to incorporate 13 C and 15 N starting from U‐ 13 C–labeled benzene to give M + 7 isotopomers. Chloroquine and its metabolites were prepared from 7‐chloro‐1,2,3,4‐tetrahydroquinolin‐4‐one through an aryl substitution with the corresponding.

Chloroquine and its analogs inhibit synthesis of nucleic acids of the parasite by affecting the matrix function of DNA. This happens by preliminary binding of the drug through hydrogen bonds with the purine fragments, and subsequent introduction of the chloroquine molecule between the orderly arranged base pairs into the spirals of the DNA of the parasite.
