    Chloroquine resistance in china


    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 resistance was first reported in both South America and South East Asia in late 1950s. Since then chloroquine resistant strains have spread throughout the ranges where the conditions are favorable for the development of the parasite especially in the regions of sub-Saharan Africa 6. There is Chloroquine resistance in a number of places in China, including the Hainan and Yunnan provinces. This is a particular problem because these are the two regions in which malaria is an endemic. Lariam and Mefloquine are usually prescribed for China but Mefloquine will not work if you are along the border of Burma in west Yunnan. Chloroquine-resistant P. falciparum first developed independently in three to four areas in Southeast Asia, Oceania, and South America in the late 1950s and early 1960s. Since then, chloroquine resistance has spread to nearly all areas of the world where falciparum malaria is transmitted.

    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.

    A severe eye problem has happened with chloroquine. This may lead to lasting eyesight problems. The risk may be higher if you have some types of eye or kidney problems. The risk may also be higher with some doses of chloroquine, if you use chloroquine for longer than 5 years, or if you take certain other drugs like tamoxifen. Summary. Resistance of Plasmodium falciparum to chloroquine CQ is determined by the mutation at K76T of the P. falciparum chloroquine resistance transporter pfcrt gene and modified by other mutations in this gene and in the P. falciparum multidrug resistance 1 pfmdr1 gene. Following the war, chloroquine and DDT emerged as the two principal weapons in WHO’s global eradication malaria campaign. Subsequently, chloroquine resistant P. falciparum probably arose in four separate locations starting with the Thai-Cambodian border around 1957; in Venezuela and parts of Colombia around 1960;
