Thapsigargin is non-competitive inhibitor of a class of enzymes known by the acronym SERCA, which stands for sarco / endoplasmic reticulum Ca2+ ATPase. Structurally, thapsigargin is classified as a sesquiterpene lactone, and is extracted from a plant, Thapsia garganica. It is a tumor promoter in mammalian cells. The anti-malarial drug artemisinin is also a sesquiterpene lactone, leading to a proposal that this class of drugs works by inhibiting the SERCA of malaria parasites such as Plasmodium falciparum; this hypothesis awaits confirmation.
