Jena, March 19, 2026 – An international research team led by Jena has achieved a historic breakthrough. Scientists have solved the centuries-old mystery of how the cinchona tree produces the life-saving malaria drug quinine.
- Success: Complete decoding of quinine biosynthesis
- Research Team: Max Planck Institute for Chemical Ecology (Jena) and University of Georgia
- Benefit: Paving the way for resource-efficient laboratory production of anti-malarial agents
Step by step to the complex molecule
The cinchona tree produces valuable alkaloids, including quinine, which is used against malaria. Exactly how the plant builds this molecular framework was considered a mystery in science for centuries. Now, researchers from the Max Planck Institute for Chemical Ecology in Jena, together with colleagues from the University of Georgia, have found the decisive puzzle pieces.
In their current study, the scientists were able to demonstrate the specific steps in which the plant synthesizes quinine. In doing so, they specifically identified the enzymes responsible as catalysts for the complex chemical reactions within the tree.
New paths for pharmacy
The findings from Jena have far-reaching consequences for medical research and the pharmaceutical industry. By understanding the exact biosynthesis, new possibilities are opening up for the efficient and sustainable production of natural substances such as quinine and closely related active ingredients directly in the laboratory in the future. This could reduce dependence on natural resources and optimize the global supply of the essential medication.
Background: Jena as a science location
The Max Planck Institute for Chemical Ecology is located on the Beutenberg Campus in the south of Jena. The campus is the heart of modern research in Thüringen and brings together numerous institutes dealing with life sciences, physics, and optics. Chemical ecology specifically researches the chemical interactions between plants, insects, and their environment – an area in which the Jena location is one of the world’s leading addresses.
