Leveraging the knowledge and synthetic expertise of our seasoned chemists, we also offer custom amino acid synthesis services from laboratory scale to production scale. We customized 12,000+ unnatural amino acids in last 5 years.
Experience Highlights
α-Me-amino acids:
- We utilize the natural amino acid Alanine to design α-Me-amino acid derivatives. This methodology can be extended to other natural amino acids, such as Leucine, Phenylalanine, etc.
N-Me-amino acids:
- We have developed a cyclization process that allows methylation to be achieved in just two steps.
PG series:
- All protecting strategies, including Boc, Fmoc, Cbz, Mtt, DDE, and IVDDE, can be implemented.
α- and β- construction series:
- We have developed enzyme catalyst techniques to construct selectable α- or β-site unnatural amino acids.
NCA series:
- We have developed a process to effectively control the quality of NCAs.
