With renewed efforts to eradicate malaria – a disease which kills up to one million people every year, most of them young children – the global demand for antimalarials is set to increase dramatically over the next four years.
The report, launched at a special meeting of the All Party Parliamentary Group for Malaria at Westminster, assesses a portfolio of new technologies, collectively known as The Artemisinin Enterprise:
• The Centre for Novel Agricultural Products at the University of York is using fast-track plant breeding to increase yields of artemisinin from the medicinal plant.
• The Institute for One World Health is using synthetic biology to produce artemisinin through fermentation and subsequent chemical conversion.
• The Medicines for Malaria Venture is developing novel synthetic artemisinin-like compounds.
The World Health Organization recommends artemisinin combination therapies (ACTs) as the most effective treatments available today. Around 100 million Artemisinin-based Combination Therapies (ACTs) were sold in 2006, but forecasts show that demand will at least double over the next four years, potentially growing to over 300 million doses annually.
Artemisinin is extracted from the medicinal plant Artemisia annua but production of the drugs is expensive and the quality variable. Uneven supplies have caused prices to vary from USD $1200/kg to $120 between 2005 and 2008 leading to high levels of uncertainty in the market for growers and pharmaceutical companies.There is growing concern that the current global supply of artemisinin cannot reliably and affordably produce the quantities or quality that will be required for ACT production.
Today’s report concludes that the outputs from all three technologies can collectively help satisfy the projected global demand for malaria treatments by providing alternative sources of artemisinin, stabilising the supply of effective antimalarial drugs such as ACTs and reducing the cost of artemisinin production.
The new technologies will only be used to support the production of high quality combination therapies for malaria. Such therapies are essential to counter the development of artemisinin resistance, a major threat to effectively fighting the disease. These technologies are envisaged to come online in the next three to seven years.
The report recommends measures to help to ensure the effective introduction of the new technologies of the Artemisinin Enterprise into the ACT supply chain. It also highlights suggestions for the wider malaria community, aimed at improving the supply of ACTs in other ways. These include creating buffer stocks, harmonizing the regulatory approach for faster ACT approvals and improving demand forecasting.
The report is based on the conclusions of the Artemisinin Enterprise Conference 2008, which was sponsored by the Bill and Melinda Gates Foundation and the Roll Back Malaria Partnership and hosted by the University of York.

Adjusting the thermal conductivity of materials is one of the challenges nanoscience is currently facing. Together with colleagues from the Netherlands and Spain, researchers from the University of Basel have shown that the atomic vibrations that determine heat generation in nanowires can be controlled through the arrangement of atoms alone. The scientists will publish the results shortly in the journal Nano Letters.
In the electronics and computer industry, components are becoming ever smaller and more powerful. However, there are problems with the heat generation. It is...

Scientists at the University Würzburg and University Hospital of Würzburg found that megakaryocytes act as “bouncers” and thus modulate bone marrow niche properties and cell migration dynamics. The study was published in July in the Journal “Haematologica”.
Hematopoiesis is the process of forming blood cells, which occurs predominantly in the bone marrow. The bone marrow produces all types of blood cells: red...
For some phenomena in quantum many-body physics several competing theories exist. But which of them describes a quantum phenomenon best? A team of researchers from the Technical University of Munich (TUM) and Harvard University in the United States has now successfully deployed artificial neural networks for image analysis of quantum systems.
Is that a dog or a cat? Such a classification is a prime example of machine learning: artificial neural networks can be trained to analyze images by looking...
An international research group led by scientists from the University of Bayreuth has produced a previously unknown material: Rhenium nitride pernitride. Thanks to combining properties that were previously considered incompatible, it looks set to become highly attractive for technological applications. Indeed, it is a super-hard metallic conductor that can withstand extremely high pressures like a diamond. A process now developed in Bayreuth opens up the possibility of producing rhenium nitride pernitride and other technologically interesting materials in sufficiently large quantity for their properties characterisation. The new findings are presented in "Nature Communications".
The possibility of finding a compound that was metallically conductive, super-hard, and ultra-incompressible was long considered unlikely in science. It was...
