Advanced Peptide Synthesis and Semi-Synthetic Technologies

Cenra API Solutions offers a full spectrum of peptide synthesis and semi -synthetic Recombinant peptide technologies, allowing us to handle peptides of varying lengths, structural complexity, and functional requirements.

Liquid Phase Peptide Synthesis (LPPS)

Suitable for short to medium-length peptides and specialized fragments requiring high flexibility or challenging chemistries.
Representative API: Carfilzomib, manufactured through Boc- based LPPS.

Solid Phase Peptide Synthesis (SPPS)

Ideal for medium to long peptides, especially those requiring difficult sequence assembly.
Examples include Etelcalcetide, Difelikefalin, and Setmelanotide, demonstrating our ability to handle disulfide bond formation, small chain peptides, and highly sensitive building blocks.

Fermentation and Semi-Synthetic approach

For complex peptide APIs that leverage both biotechnology and chemical steps.
Representative project: Semaglutide, produced through hybrid fermentation and synthetic methodologies to achieve ultra high purity and effective control of High Molecular Weight Proteins (HMWP) and unidentified impurities.

Hybrid Convergent Peptide Synthesis

Specialized expertise in multi fragment assembly and controlled disulfide bond formation.
Representative project Plecanatide, a medium‑chain peptide containing multiple disulfide bridges and requiring highly sophisticated purification processes.
By leveraging these diverse technologies, we design the most suitable synthetic route for each peptide—achieving optimal cost efficiency, high purity, and robust scalability.

Analytical Capability

Comprehensive analytical services are available, including physical, chemical property testing, polymorph analysis, reference standard preparation and qualification, analytical method development and validation, as well as ICH-compliant stability studies.
