    Chloroquine undergoes appreciable degradation in the body. The main metabolite is desethylChloroquine, which accounts for one fourth of the total material appearing in the urine;bisdesethylChloroquine, a carboxylic acid derivative, and other metabolic products as yet uncharacterized are found in small amounts. Chloroquine, synthetic drug used in the treatment of malaria. 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. 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.

  3. Here we examined the effect of chloroquine on the synthesis and metabolism of TNF-R in human histiocytic U-937 cells. In PMA-stimulated cells, chloroquine reduced the level of soluble and cell surface TNF-R, while cell-associated TNF-R was increased by chloroquine. Chloroquine had no effect on the level of p55 and p75 TNF-R mRNA.

    Additionally the total synthesis give us the opportunity to synthesized chemically relevant analogs, and getting a derivative with higher pharmacological activity. Figure 1 Some naturally occurring compounds which became into approved drugs for the treatment of different diseases. 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. The first total synthesis of malagashanine, a chloroquine potentiating indole alkaloid, is presented. A highly stereoselective cascade annulation reaction was developed to generate the tetracyclic core of the Malagasy alkaloids. This chemistry is likely to be broadly applicable to the synthesis of other memb

    Eye screening for patients taking hydroxychloroquine Plaquenil Abnormal test is the visual field test, you may be asked to repeat it to make sure of the results. You will be told if any other tests are necessary and when you should be screened again.
