Lab Background

Kratena Research Group

Exploring the frontiers of Organic Synthesis and Medicinal Chemistry at TU Wien.

Research Focus

Our group combines synthetic methodology with biological application to solve complex problems in molecular sciences.

Bio-inspired synthesis of terpenoids

Our research in this area focuses on developing biomimetic strategies to access bioactive, rearranged terpenoids. We mimic nature's biosynthetic logic to efficiently transform abundant natural precursors into diverse libraries of high-value molecular scaffolds. This divergent, semi-synthetic platform serves as a powerful engine for uncovering new chemical entities and accelerating drug discovery.

Photoaffinity probes & MCRs

In collaboration with Solgate GmbH, we are designing fragment-based photoaffinity probes. We develop novel methods to synthesize small molecules containing photoactive functional groups (diazirines), employing high-throughput synthesis to create libraries for biological evaluation.
