Drug Discovery & Optimization

JPT applies its proprietary peptide technologies, bioinformatic and medicinal chemistry know-how and decade-long track record managing R&D projects and R&D collaborations in the following areas: 

Peptide Chemistry     Peptide Optimization 

Our experience in drug discovery and optimization can be applied in peptide based drug and vaccine projects, in the discovery of peptidic additives for the cosmetic and nutritional industry, in the development of affinity ligands for the purification of biomolecules, as well as in content determination for novel immune diagnostics.



  • Discovery of peptidic agonistic or antagonistic ligands for proteins, protein complexes or antibodies
  • Optimization of peptides in terms of binding affinity, agonistic or antagonistic efficacy and physicochemical and PK properties 
  • Identification and optimization of affinity ligands for the purification of therapeutic proteins or antibodies
  • Identification and optimization for the development of alternative binding assays for complicated target proteins (e.g. membrane proteins) 
  • Development of peptides as active ingredients or excipients in drug formulations (e.g. to increase stability) or nutritional and cosmetic products, respectively
