Alternative ways of producing artemisinins are discussed here in the light of a recent paper in BMC Biotechnology on improving the yield of the precursor artemisinic acid in genetically engineered yeast. Artemisinin derived from sweet wormwood Artemisia annua is the spearhead of anti-malarial chemotherapy. In 2004 the World Health Organization WHO recommendation that artemisinin-based combination therapy ACT should be the norm for the treatment of falciparum malaria in most endemic countries came into effect 1 . Financial backing for this treatment from the Global Fund for AIDS Tuberculosis and Malaria and other international sponsors has led to a massive increase in the demand for artemisinin but with an estimated 12-14 months lead-time from planting of A. annua to artemisinin extraction stepping-up production or adjusting to fluctuations in demand from the plant is not simple and alternative means of producing the raw material by complete chemical synthesis or recombinant technologies are being explored. It would however be naive to believe that the cost of the raw material is the main determinant of the cost of a drug. This article looks at issues surrounding the production of artemisinins particularly in the light of a recent paper by Jay Keasling and colleagues Ro et al. 2 in BMC Biotechnology which describes a way of improving the yield of the precursor .
