Since its discovery from the extracts of sweet wormwood (Artemisia annua) in 1979. the anti-malarial drug artemisinin (3) is now the key starting material in the synthesis of life-saving artemisinin-based combination therapies (ACT). Yet. beginning in 2009. mutations in the parasites PfKelch13 protein began conferring artemisinin resistance in the Greater Mekong Subregion (GMS) (Figure 1).Since then. artemisinin resistance has been spreading and some ACT treatment failure rates have reached 26% to 46% in 2015.
