Abstract

Chloroquine (CQ) is the most successful antimalarial drug ever discovered. Unfortunately, parasites resistant to the drug eventually emerged after its large scale use and are now widespread. Although great progress in our understanding of the mechanisms of CQ action and CQ resistance (CQR) has been achieved over the past two decades, including the identification of the molecules responsible for CQR (e.g., Plasmodium falciparum chloroquine resistant transporter, PfCRT) many questions remain unanswered. Here we highlight recent advances in our understanding of the genetics and molecular mechanisms of CQR, with particular emphasis on the role of genes such as pfcrt and pfmdr1 in the resistance to CQ and other drugs. New drug development and applications will undoubtedly benefit from a better understanding of CQR, eventually leading to more effective malaria control measures.
