    Synthesis of chloroquine phosphate slideshare


    One of these ways consists of reacting 3-chloroaniline with ethoxymethylenmalonic ester to make (3-choroanilino)-methylenemalonic ester (37.1.1.4), which then undergoes high-temperature heterocyclization to make the ethyl ester of 7-chloro-4-hydroxyquinolin-3-carboxylic acid (37.1.1.5). Hydrolyzing this with sodium hydroxide gives 7-chloro-4-hydroxyquinolin-3-decarboxylic acid (37.1.1.6), which when heated at 250–270 C is decarboxylated, forming 7-chloro-4-hydroxyquinoline (37.1.1.7).

    Chloroquine inhibits polymerization of heme and accumulation of heme. • Chloroquine binds to heme or fp to form what is known as the fp-chloroquine complex, this complex is highly toxic to the cell and disrupts membrane function. Action of the toxic compound results in cell lysis and ultimately parasite cell autodigestion. 13. [email protected] This feature is not available right now. Please try again later.

    Alkaline hydrolysis of the ethyl ester of the 7-chloro-4-hydroxyquinolin-2-carboxylic acid (37.1.1.9) and subsequent high-temperature decarboxylation of the resulting acid (37.1.1.11) gives 7-chloro-4-hydroxyquinolin (37.1.1.7). Treating this with phosphorus oxychloride gives one of the desired components for synthesis of chloroquine – 4,7-dichloroquinoline (37.1.1.1) [The second method of preparing of 4,7-dichloroquinoline (37.1.1.1) consists of reacting 3-chloroaniline with the diethyl ester of oxaloacetic acid in the presence of acetic acid to give the corresponding enamine (37.1.1.8), which when heated to 250 °C undergoes heterocyclization to the ethyl ester of 7-chloro-4-hydrozyquinolin-2-carboxylic acid (37.1.1.9) accompanied with a small amount of 5-chloro-4-hydroxyquinolin-2-carboxylic acid (37.1.1.10), which is separated from the main product by crystallization from acetic acid.

    Can we get chloroquine from 4-amino-7-chloroquinoline 7-chloroquinolin-4-amine by adding 4-chloro-N,N-diethylpentan-1-amine $\ce{CH3CHClCH23NEt2}$ ? Stack Exchange Network Stack Exchange network consists of 175 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their. The clinical usefulness of chloroquine, and in some recent cases of quinine as well, has been much reduced by the evolution and spread of chloroquine resistant malaria parasites. The mechanism of resistance involves a reduced accumulation of the drug, although again the mechanism involved is controversial. 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.

    Treating Lupus with Anti-Malarial Drugs Johns Hopkins Lupus Center Three anti-malarial drugs are prescribed for lupus symptoms. Hydroxychloroquine Plaquenil is the most commonly prescribed because it is generally believed to cause fewer side effects; chloroquine Aralen has a reputation for more serious side effects, but it may be prescribed in situations where hydroxychloroquine cannot be used.
