One of these ways consists of reacting 3-chloroaniline with ethoxymethylenmalonic ester to make (3-choroanilino)-methylenemalonic ester (126.96.36.199), which then undergoes high-temperature heterocyclization to make the ethyl ester of 7-chloro-4-hydroxyquinolin-3-carboxylic acid (188.8.131.52). Hydrolyzing this with sodium hydroxide gives 7-chloro-4-hydroxyquinolin-3-decarboxylic acid (184.108.40.206), which when heated at 250–270 C is decarboxylated, forming 7-chloro-4-hydroxyquinoline (220.127.116.11). Does hydroxychloroquine sulfate make you tired Downes sm hydroxychloroquine retinopathy Hydroxychloroquine myositis What does chloroquine do in transfection Chloroquine can inhibit a pre-entry step of the viral cycle by interfering with viral particles binding to their cellular cell surface receptor. Chloroquine was shown to inhibit quinone reductase 2, a structural neighbour of UDP-N-acetylglucosamine 2-epimerases that are involved in the biosynthesis of sialic acids. The sialic acids are acidic. Chloroquine phosphate tablets, Chloroquine phosphate, USP, is a 4-aminoquinoline compound for oral administration. It is a white, odorless, bitter tasting, crystalline substance, freely soluble inwater. Chloroquine phosphate tablets are an antimalarial and amebicidal drug. Chloroquine 4-Aminoquinoline derivatives Uncharged at neutral pH Diffuse freely into lysosome of parasite At acid pH of lysosome, it converted to a protonated, membrane impermeable form and is ‘trapped’ inside the parasite. At high conc. It inhibits protein RNA and DNA synthesis. 13 14. Alkaline hydrolysis of the ethyl ester of the 7-chloro-4-hydroxyquinolin-2-carboxylic acid (18.104.22.168) and subsequent high-temperature decarboxylation of the resulting acid (22.214.171.124) gives 7-chloro-4-hydroxyquinolin (126.96.36.199). Treating this with phosphorus oxychloride gives one of the desired components for synthesis of chloroquine – 4,7-dichloroquinoline (188.8.131.52) [The second method of preparing of 4,7-dichloroquinoline (184.108.40.206) consists of reacting 3-chloroaniline with the diethyl ester of oxaloacetic acid in the presence of acetic acid to give the corresponding enamine (220.127.116.11), which when heated to 250 °C undergoes heterocyclization to the ethyl ester of 7-chloro-4-hydrozyquinolin-2-carboxylic acid (18.104.22.168) accompanied with a small amount of 5-chloro-4-hydroxyquinolin-2-carboxylic acid (22.214.171.124), which is separated from the main product by crystallization from acetic acid.

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.
