Chloroquine has been extensively used in mass drug administrations, which may have contributed to the emergence and spread of resistance. It is recommended to check if chloroquine is still effective in the region prior to using it.

Chloroquine and hydroxychloroquine have been prepared for pharmacological studies, the synthesis of their stable labeled internal standard has not been described in details. In this paper, the synthetic route to 2H 4 chloroquine, 2H 5 hydroxychloroquine and their metabolites were described in detail. EXPERIMENTAL SECTION General Hydroxychloroquine HCQ, sold under the brand name Plaquenil among others, is a medication used for the prevention and treatment of certain types of malaria. Specifically it is used for chloroquine-sensitive malaria. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth. The Centers for Disease Control and Prevention recommend against treatment of malaria with chloroquine alone due to more effective combinations. In areas where resistance is present, other antimalarials, such as mefloquine or atovaquone, may be used instead.

Hydroxychloroquine - Wikipedia. A practical synthesis of the enantiomers of hydroxychloroquine. Abstract. The effects of hydroxychloroquine on the growth of several mammalian cell lines have been studied. ML-388 cells were no more sensitive to hydroxychloroquine than were other cell lines tested; all cell lines, including the steroid-resistant ML-388R, required about 1 x 10-5 M hydroxychloroquine for 50% inhibition of growth. Hydroxychloroquine inhibits the IL-1β synthesis from SAA-stimulated neutrophils. Neutrophils were pretreated with the indicated concentrations of hydroxychloroquine or iberiotoxin IBTX for 1 h and stimulated with SAA 10 μg/ml for 24 h, and supernatants were analyzed for IL-1β production by ELISA. In 1950, chemists Alexander R. Surrey and Henry F. Hammer at the Sterling–Winthrop Research Institute Rensselaer, NY published a synthesis of hydroxychloroquine. The parent company, Sterling Drug, obtained a US patent on the compound and its method of preparation the same year.
