De novo PROTAC Design Solution

Targeted protein degradation by Proteolysis-Targeting Chimeras (PROTACs) for undruggable drug targets.

Context

PROTACs for undruggable drug targets

Proteolysis Targeting Chimeras (PROTACs) represent a paradigm shift in drug discovery and therapeutic intervention, offering a powerful approach to address previously “undruggable” targets. By harnessing the cell’s own protein degradation machinery, PROTACs open new avenues for treating diseases ranging from cancer to neurodegenerative disorders.

Why Choose PROTACs?

Biologic therapies (like monoclonal antibodies and oligonucleotides) offer some solutions, but they suffer from delivery limitations, particularly to specific tissues.

PROTACs can potentially overcome limitations of traditional small molecule inhibitors, particularly for challenging targets such as transcription factors and scaffold proteins.

Unlike small-molecule inhibitors that bind to a target protein and block its activity, PROTACs bind to a target protein and then facilitate its degradation by leveraging the UPS (ubiquitin-proteasome system), which is the cell's natural protein disposal system.

Our Solution

The Aganitha Advantage

  • Advanced Structural Modeling: We begin with precise modeling of the Protein of Interest (POI) and E3 ligase complex, ensuring a solid foundation for PROTAC design. 
  • High-Affinity Ligand Screening: Our GPU-accelerated virtual screening platform rapidly identifies high-affinity ligands for both the POI and E3 ligase. 
  • Synthesizable Linkers: We employ a library of laboratory tested synthesizable linkers.
  • Comprehensive Hit Identification: Our automated PROTAC construction and evaluation process considers multi-parameter optimization, binding affinity, and predicted degradability of the ternary complex.
  • Advanced Hit-to-Lead Optimization: We utilize deep learning-based degradability prediction to optimize PROTAC architecture, and MD simulations to refine candidates, ensuring optimal ternary complex formation and stability.
