Pharmaceutical R&D

Genetic code expansion (GCE) allows the site-specific incorporation of non-canonical amino acids (ncAAs), which serve as new building blocks for studying and altering proteins. Leveraging the innovative GCEngine platform with deep expertise in preclinical services, our company empowers pharmaceutical researchers to overcome traditional limitations in drug discovery and development. By enabling the site-specific incorporation of ncAAs into target proteins, this cutting-edge technology facilitates the creation of novel molecular entities with enhanced properties, supporting the development of next-generation therapeutics.

Applications of ncAA Incorporation in Pharmaceutical R&D

GCE technology provides a foundational technology for designing the next generation of biologics. By enabling the site-specific incorporation of ncAAs, it unlocks a diverse array of powerful applications critical to modern drug development.

  • ncAA Incorporated Peptide Engineering
    Enhances the metabolic stability and bioavailability of therapeutic peptides by incorporating ncAAs that resist protease degradation or improve physicochemical properties, thereby addressing challenges like rapid clearance.
  • ncAA Incorporated Antibody Engineering
    This technology enables site-specific conjugation, generating homogeneous antibody-drug conjugates (ADCs) with defined drug-to-antibody ratios (DAR). This results in more effective and safer targeted therapies with reduced off-target toxicity.
  • ncAA Incorporated Vaccine Development
    It facilitates the creation of novel vaccines by incorporating precisely modified antigens to elicit a stronger and targeted immune response. This strategy can be particularly valuable for designing vaccines against complex pathogens and cancer.
  • ncAA Incorporated Protein Engineering
    Site-specifically introducing novel functional groups into protein therapeutics to modulate their activity, stability, and pharmacokinetics. This capability accelerates the development of optimized protein drugs and bioconjugates.
