Antimalarial flow synthesis closer to commercialisation

Scientists in Germany have demonstrated the large scale and inexpensive production of a range of antimalarial drugs, using a continuous flow system.

The processes yields several artemisinin-derived APIs that are key components in Artemisinin Combination Therapies

An important starting material for various anti-malarial drugs is artemisinin, which until recently could only be obtained by extraction from the plant Artemisia annua. As Peter Seeberger, from the Max Planck Institute for Colloids and Interfaces in Potsdam, explains, ‘the problem is that the drug is too expensive, such that in Africa and south east Asia between 40 and 50% of the artemisinin combination therapies are fake.’

Optimising multi-enzyme reactions – enabling enzymatic encoding

The ability to mimic cascade and linked enzyme reactions has potential applications for disease diagnosis and pharmaceutical manufacturing, to name just two. However, the optimisation of the ratios of the interacting enzymes can be a time consuming step when carried out using standard solution based enzyme assays. With the problem becoming exponentially more difficult with the number of enzymes in the system, Jun Ge and Zheng Liu of the Department of Chemical Engineering at Tsinghua University, with colleagues, have looked to overcome this hurdle by developing a simple, fast and high throughput method based on ink-jet printing. 

The team replaced the colour inks in a standard inkjet printer with enzyme and substrate solutions. The ratio of these solutions could be controlled by varying the overall colour that was printed. Optimisation of cascade and coupled enzymatic reactions could be carried out rapidly and inexpensively compared to the standard solution based method. 

Enzymatic encryption, decoding and deletion of information

Precise two-dimensional control of enzyme placement via ink-jet printing also raises the possibility of creating 2D codes with enzymatic encryption built in, as the figure demonstrates. I don’t want to give the secret of this encryption technique away so you’ll have to read the paper today. 

To read the details, check out the ChemComm article in full:
