Two deadly flowers could inspire powerful new medicines
Scientists have figured out how two famously poisonous plants create chemicals with surprising medical potential. After tracking thousands of genes in wolfsbane and larkspur, they identified six enzymes needed to build a complex compound called atisinium. The team recreated the process inside tobacco plants, offering a sustainable way to produce and test these rare molecules in larger amounts.
Two poisonous plants, wolfsbane and larkspur, may hold the key to developing powerful new medicines, according to researchers from Michigan State University and the Czech Academy of Sciences. The plants, which have been used in traditional medicine for centuries, contain compounds that can cause nerve damage and paralysis even in low doses.
However, scientists have now identified a way to recreate part of this potent chemistry in a laboratory setting, offering a potential path toward more sustainable treatments based on natural products. The findings, published in the journal Molecular Plant, could lead to innovative ways to test new medicines and address challenges in drug development.
Plants are unparalleled chemists, evolving over millions of years to produce intricate natural compounds that benefit their survival. These compounds have found numerous applications in everyday life, from caffeine and capsaicin to menthol and vanillin. The Hamberger Lab at Michigan State University specializes in studying these specialized metabolites and exploring their practical uses.
In this case, researchers focused on larkspur, also known as delphinium, and its production of diterpenoid alkaloids. These chemicals are highly toxic but may have valuable medical properties. The project involved an unexpected partnership between researchers from Michigan State University and the Czech Academy of Sciences, who joined forces after meeting at a scientific conference in Barcelona.
By identifying the precise sequence of biochemical steps used by the plants to create diterpenoid alkaloids, the international team was able to transfer the genetic instructions for building these compounds into tobacco plants. This allowed the plants to produce atisinium, a diterpenoid alkaloid, demonstrating the success of the research.
The discovery opens up new possibilities for creating sustainable, natural-based treatments inspired by these powerful plants.
