Malaria is a fatal yet preventable and treatable disease. It is commonly spread through the bite of an infected Anopheles mosquito. Malaria parasites belong to the Plasmodium genus and can be caused by the falciparum, malariae, ovale, vivax, and knowlesi species. Artemisinin is an endoperoxide lactone extracted from qinghaosu (Artemisia annua L. or sweet wormwood). It and its derivatives possess uncharacteristically rapid action against Plasmodium falciparum. Artemisinin is unique in its effectiveness in deadly cerebral malaria. The endoperoxide bridge is crucial for its antimalarial activity; however, how it aids in killing the parasite is unknown. While there are multiple suggested …

Part A: Antimalarial Agents modified at the C-16 position of Artemisinin. Malaria is a widespread tropical and subtropical parasitic disease which is caused by malarial parasites and transmitted by the infected anopheles mosquitoe. The natural product artemisinin and its derivatives are currently considered the most effective drugs against drug resistant plasmodium falciparum. However, its undesired physicochemical proprieties have limited its usage. In order to improve its effectiveness, scientists around the world have developed novel methodology to synthesize artemisinin derivatives on different positions of the artemisinin skeleton. Previous work in our group has shown that many analogues modified at the C-16 …
