The mechanism of action of artemisinin and its derivatives, the most potent of the anti-malarial drugs, is not completely understood. Here we present an unbiased chemical proteomics analysis to directly explore this mechanism in Plasmodium falciparum. We use an alkyne-tagged artemisinin analogue coupled with biotin to identify 124 artemisinin covalent binding protein targets, many of which are involved in the essential biological processes of the parasite.

Article Synopsis
  • Chloroquine was an effective treatment for the malaria-causing parasite Plasmodium falciparum, but resistance has developed, prompting research on ways to overcome this resistance.
  • A new fluorescent chloroquine-BODIPY conjugate, LynxTag-CQGREEN, has been introduced as a safer alternative to monitor chloroquine accumulation in the parasite's digestive vacuole, showing stronger effects on chloroquine-sensitive strains than resistant ones.
  • Studies on parasite strains indicated that LynxTag-CQGREEN's uptake was affected by the type of PfCRT protein and was influenced by known chemosensitizers, with correlations found between drug uptake and genetic mutations related to drug resistance.
