Scientific Background

More than 10% of the human proteome contains PRM-binding domains – a class of protein-domains specialized in the recognition of proline-rich motifs.

These domains are involved in a multitude of pathologies, such as cancer, Alzheimer’s and other neurodegenerative diseases, cardiovascular diseases, immune-meditated disorders, etc.

However, they are so far considered as „undruggable“, making peptidomimetic and small molecule competitors of PRM urgently needed.

PROSION’s ProM Platform

Through a unique design concept, PROSION established a platform of synthetic Proline-derived modules (ProMs) as the world’s first validated and patented PRM-structure mimicking scaffolds. As stereo-defined building blocks, these can be assembled into urgently needed competitors of PRM. 

Based on this disruptive technology, PROSION is able to develop first-in-class small molecule drugs, for a particularly abundant class of undruggables – finally making PRM binding domains druggable.

Generating ProM-based compounds for drug development

We are striving to push our own drug compounds through pre-clinical and clinical development. The first candidate that we are developing is a highly selective ProM-based inhibitor for addressing solid tumor cancer metastasis.

While this is the first POC, the platform has the potential to address various targets and indications.

Providing ready-to-use ProMs as lead compounds

ProMs are the first reported and patented mimetics of a very abundant secondary structure of our organism and have thus a vast use-potential in a multitude of areas next to drug discovery (e.g. PROTACs, Biotools, etc.).

We therefore offer a broad range of ProMs, enabling our potential partners to gain an in-depth scientific understanding.
