About the project

Naturally occurring active agents with often interesting physiological properties have been of huge interest in all times. Several cytotoxic agents could be isolated from marine organisms that are considered to be potential anti‐tumour agents. The families of bryostatins and pederins are two interesting classes of natural products which were actually isolated from marine organisms. An efficient access to the key structures of Bryostatin and Psymberin is desirable.

The focus of the project lies on the central tetrahydropyran (THP) which can be found as a substructure of both natural products. An efficient synthesis should be achieved by chemo‐enzymatic methods using aldolases. However, the desired key structure may not be accessible by using a wild type aldolase because of it’s stereoselectivity and in addition, the usage of a sterically challenging aldehyde as the substrate. Using directed evolution, the wild type enzyme should be adapted to its particular duty. The variants should be obtained by an enzyme screening based on fluorescence.
