Targeted Protein Degradation

Why TPD?

Protein degradation offers advantages to improve clinical outcomes:

  1. Target enzymatic and non-enzymatic roles
  2. Opportunity to target less conserved regions of the protein of interest vs related family members
  3. Target historically “undruggable” proteins
  4. Catalytic mechanism reduces the drug concentration required at site of action
POI (protein of interest) added to E2/E3 ligase complex, with ubiquitin. Multiple ubiquitous added to target for degradation. Ubiquitinated POI recruited to proteasome. Proteasome degrades POI.

Targeted Protein Degradation

Cells have innate machinery called the Ubiquitin Proteasome System (UPS) to control the expression levels of proteins in normal and disease settings. Targeted heterobifunctional and molecular glue degraders can hijack the cell’s UPS to degrade disease-causing protein.

Breaking Through the Limits of TPD

SK Life Science Labs’ R&D leadership team has a proven track record in drug hunting. Together with our team of exceptional scientists, SK Life Science Labs integrates innovative platforms with deep drug-hunting expertise to defeat disease and improve patients’ lives.

Heterobifunctional TPD companies primarily use CRBN and VHL, Molecular glue TPD companies predominantly exploit CRBN of phenotypic discovery. SKLSL target-centric approach and MOPED platform expands access to a wider range of targets and E3s. (Abbreviations: CRBN, cereblon; VHL, von Hippel-Lindau)

Our team utilizes AI-enabled target identification to prioritize novel drug targets. Our core TPD platform, built upon a strong TPD knowledge base, novel E3 ligands & linkers, and machine-learning based ternary complex modeling, is further complemented by a proprietary MOPED™ molecular glue platform. SK Life Science Labs’ capabilities are leveraged from target identification through preclinical development to deliver first or best-in-class medicines to patients.
