Pairing algorithm

With hundreds of cancer selective intracellular protein markers and hundreds of proteins with essential function to choose from, we have developed an algorithm to help select complementary pairs to begin the RIPTAC therapeutic design.

Ligands and linkers

There are three critical components to a RIPTAC therapeutic:

• Ligand for the tumor-specific targeting protein
• Linker
• Ligand for the protein with essential function

Halda takes advantage of today’s advanced tools for structure-based drug design and internal expertise of bifunctional molecule design and synthesis to ensure proper alignment of proteins to drive the formation of neo protein-protein interactions and selective cell death.

In Vitro / In Vivo Analysis

Once designed, we iteratively test the kinetics of ternary complexes containing the RIPTAC therapeutic and both proteins, and we assess the downstream pharmacodynamic effects.
