artemisinins

Wednesday 31 May 2006

Combinations of an artemisinin with other antimalarial drugs are now recommended treatments for Plasmodium falciparum malaria in most endemic areas.

Several individual molecules have been proposed as targets for artemisinins, in addition to the idea that artemisinins might have many targets at the same time.

Artemisinins could inhibit the parasite-encoded sarco-endoplasmic reticulum Ca(2+)-ATPase (SERCA) PfATP6. A polymorphism in the gene encoding PfATP6 is associated with in vitro resistance to artemether in field isolates of P. falciparum.
