According to legend it was first brought to Europe by a Countess who had been treated with it in Peru in the 1600s. In 1820, two French chemists isolated quinine from the cinchona bark and quinine became a treatment of reference for intermittent fever throughout the world. Quinine remains an important and effective treatment for malaria today, despite sporadic observations of quinine resistance.

In discussions of SAR, particular emphasis has been given to activity versus chloroquine resistant strains of Plasmodium falciparum. Objective Malaria is an infectious disease commonplace in tropical countries. For many years, major antimalarial drugs consisted of natural products, but since 1930s these drugs have been largely replaced with a series of synthetic drugs. This article. These compounds belonged to a new class of antimalarials, the four-amino quinolines. Research by German scientists to discover a substitute for quinine led to the synthesis in 1934 of Resochin (chloroquine) and Sontochin (3-methyl-chloroquine).

Chloroquine is an aminoquinoline used for the prevention and therapy of malaria. It is also effective in extraintestinal amebiasis and as an antiinflammatory agent for therapy of rheumatoid arthritis and lupus erythematosus. Pharmacology of Chloroquine Mechanism of Action As mentioned earlier, chloroquine is effective against the erythrocytic form of the Plasmodium parasite. Chloroquine is able to accumulate at very high concentrations within the acid compartments of the parasite. At present, the absolute mechanism of accumulation of the drug is still under debate. Chloroquine — Chloroquine was the first drug produced on a large scale for treatment and prevention of malaria infection. Chloroquine has activity against the blood stages of P. ovale, P. malariae, and susceptible strains of P. vivax and P. falciparum.
