CYpHER technology offers a novel approach to targeted protein degradation (TPD) by utilizing pH-dependent endolysosomal delivery and recycling. This method enhances drug potency and reduces off-target risks for treating diseases like cancer.
Area of Science:
- Biochemistry
- Molecular Biology
- Drug Discovery
Background:
- Conventional inhibitors often fail to address multiple pathogenic mechanisms of disease-causing proteins.
- Targeted protein degradation (TPD) offers a strategy to eliminate disease proteins by hijacking cellular machinery.
- Existing TPD strategies involve E3 ligases or endolysosomal pathway uptake.
Conclusions:
- CYpHER technology provides a potent and durable TPD strategy.
- Its pH-dependent and TfR-mediated mechanism offers advantages in efficacy and safety.
- CYpHER shows promise for treating EGFR-driven cancers and other TfR-expressing tumors.

The Proteasome
In this pathway, the target proteins are first tagged with small proteins called ubiquitin. A series of enzymes carry out the ubiquitination of the target proteins - E1 (ubiquitin-activating enzyme), E2 (ubiquitin-conjugating enzyme), and E3...
