Irini Pateraki tries to elucidate the natural biosynthetic pathway of the medicinal drug forskolin in the plant Coleus forskohlii. She recently was author on a featured publication in the Journal Plant Physiology showing the first results of her project along with in planta localization studies for forskolin.

Research
The labdane diterpene forskolin has long been recognized for its pharmaceutical properties. Most important, forskolin increases intracellular cAMP levels which then assist in the relaxation of human blood and respiratory vessels. In nature, forskolin is produced in the roots of the plant Coleus forskohlii, but until now the precise biosynthetic pathway and production site of forskolin was unknown.
During our task to elucidate the natural biosynthetic pathway of forskolin we were already able to show that the first two steps of the biosynthesis of the drug forskolin are active in Coleus forskohlii root cork cells. Here, forskolin and other bioactive terpenoids are stored in lipid bodies (LBs). This indicates a unique and novel function for these lipophilic intracellular compartments. 


 

Chemical analysis of these root oil bodies revealed that they have the capacity to store an array of terpenoids, including forskolin and its biosynthetic precursor, manoyl oxide. We identified and characterized two diterpene synthases that are involved in the synthesis of manoyl oxide, the first steps of forskolin biosynthesis. These findings will assist in future discoveries of the remaining biosynthetic components, thus potentially leading to sustainable forskolin production through biotechnological applications.
