Peptide Conjugation Services

Peptide conjugation has revolutionized the field of peptide therapeutics for rare diseases. It makes peptides more suitable for clinical applications. Our company offers a full range of peptide conjugation services, which can help you make progress in the development of rare disease peptide therapies.

Introduction to Peptide Conjugation

Intrinsic limitations of peptides have impeded the development of effective rare disease drugs. The two major constraints in peptide drug development are their poor oral bioavailability and short half-life in the bloodstream. However, peptide conjugation offers promise. By attaching molecules to peptides, researchers can improve their drug capabilities and target delivery. This breakthrough approach improves bioavailability and stability, enhancing their therapeutic potential for rare diseases.

Advantages of Peptide Conjugation

  • Extending Plasma Half-life: Conjugating peptides with moieties that increase their size, such as polyethylene glycol (PEG), allows them to evade kidney filtration, resulting in reduced clearance from the bloodstream, leading to sustained therapeutic effects.
  • Enhanced Stability and Protection: The addition of conjugation can stabilize the structure of therapeutic peptides, minimizing enzymatic degradation. Glycosylation and encapsulation are forms of conjugation that offer protection from extracellular proteases, further increasing peptide stability.
  • Improved Pharmacokinetics: Conjugating peptides with drugs that have inherent bioactivity allows them to follow the same metabolism and elimination routes as their endogenous counterparts. This compatibility with the body's natural processes enhances the pharmacokinetics of peptide conjugation, making them well-suited for therapeutic for rare diseases.
