Total and semi synthesis of natural product derived drugs

Natural products are a rich source of bioactive compounds with promising potential to be further developed into drug candidates. However, natural products often need to be chemically modified in order to improve their pharmacokinetic properties or increase their bio activity to serve as candidates for drug developement. 

Furthermore, some natural products have to be generated by total synthesis to be able to modify certain molecular positions or provide the compound in sufficient amounts.

One natural compound currently in focus of our research is Griselimycin, a cyclodepsi decapeptide which have been isolated from Streptomyces griselius, showing selective antimycobacterial activity including activity against MDR Mycobacterium tuberculosis. We are working on semi synthetic derivatization and total synthesis of novel Griselimycin derivatives in order to eliminate off-target effects and increase activity.
