Glycochemistry : sugar engineering and active ingredient delivery

Enhancing the efficacy, stability, and specificity of molecules through glycoscience​

Are you looking to solubilize a hydrophobic active ingredient, develop targeted therapies (AAV), design effective vaccines, or create bio-guided cosmetic ingredients?

To address these challenges, CAPACITÉS transforms the complexity of sugars into concrete R&D solutions for the pharmaceutical, cosmetics, and nutrition industries.

Summary

Services

No matter what challenges you face, our experts provide you with practical and innovative solutions.

Glycochemistry and molecular targeting​

Although your active ingredients show promise, they often lack specificity or cause adverse effects.

The attachment of targeted sugar moieties (site-selective glycoconjugation) transforms your molecules into “guided missiles” recognized by specific cellular receptors (lectins).

  • Increased therapeutic index and reduced toxicity.
  • Modification of the surface of viral capsids (AAV) and antibodies (ADC).
  • Development of glycoconjugate vaccines that elicit a strong immune response.

Solubility and stability of active ingredients​

In fact, many active ingredients remain difficult to utilize due to their insolubility in water or their instability.

Therefore, we use commercially available, chemically modified cyclodextrins to encapsulate and protect the target molecule.

  • A 10- to 100-fold increase in bioavailability and water solubility.
  • Prolonged, time-controlled release (slow-release).
  • Protection against oxidation and masking of odors and bitterness.

Our expertise in sugar chemistry

  • Organic Synthesis: Custom synthesis of complex carbohydrate molecules, from proof of concept to pilot-scale production.
  • Bioconjugation and targeting: Covalent and site-specific grafting of glycan motifs onto proteins, peptides, antibodies, and nanoparticles.
  • Vectorization and Formulation: Design and modification of custom cyclodextrins for the microencapsulation of active ingredients (cyclodextrin encapsulation, improved bioavailability, active ingredient, solubilization of hydrophobic molecules).
  • Interactions and screening: Detailed analytical characterization, quantification of glycomolecules, and validation of inhibition on biological targets (measurement of sugar-protein affinity, lectin inhibition assay, glycan-receptor interactions, HPAEC-PAD quantification)

    Cyclodextrins for Microencapsulation

    Cyclodextrins have an inclusion capacity that enables many hydrophobic compositions to become soluble in an aqueous solution.

    There are many uses for this molecular tool, such as controlling the release of scents and flavors, improving the bioavailability of a therapeutic compound, capturing pesticides, encapsulating toxic organic compounds present in water, etc.
