    Chloroquine resistance development

    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.

    Chloroquine is commonly used to study the role of endosomal acidification in cellular processes 2, 3, such as the signaling of intracellular TLRs. Moreover, Chloroquine inhibits autophagy as it raises the lysosomal pH, which leads to inhibition of both fusion of autophagosome with lysosome and lysosomal protein degradation. Factors that promote the development of drug resistance are more intense with P. falciparum compared to P. vivax and this explains the higher incidence of resistance in P. falciparum. Mechanisms of resistance. The biochemical mechanism of resistance has been well understood in cases of chloroquine, the antifolates, and atovaquone.

    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).

    In contrast, for Central American countries except Panama and the island of Hispaniola, CQ continues to be the first line of treatment of P. falciparum malaria, because there is no evidence for the presence of CQ resistance in Central America outside of Panama, Mexico, or the Caribbean islands. Also contributing to the development of resistance was the widespread availability of chloroquine in shops and private pharmacies, lax regulation of use of the drug, and the absence of effective. The malaria parasite's development of resistance to the drug chloroquine is a major threat to world health. A protein likely to be involved in chloroquine resistance has recently been identified; this discovery is important, but raises as many questions as it answers.
